If you’re any good at Ruby, this is probably not the first job ad you’ve seen, so we’ve done our best to stand out while also accurately presenting what we’re all about. If it sounds like you would enjoy working with us, don’t hesitate to apply or drop us a line with questions on engineering-recruitment@silverfin.com.

Ahum. Here it comes.

What’s a Silverfin?

At Silverfin we’re trying to apply the promise of software to the age-old industry of accounting. With our SaaS we’re automating a large chunk of the busy-work that accountants are currently handling manually, and are building new tools so they can provide better services to their customers. We aim to optimize their workflow in such a way that accountants can spend more time on the much more impactful and rewarding work of advising their customers, the business owners.

The good news is we’re succeeding in doing exactly that. Every day more than 15.000 financial service professionals use Silverfin to help and advise more than 200.000 businesses. Our customers adore us! The even better news is there’s still plenty left to work on, and that’s where we hope you come in.

What makes the engineering team at Silverfin special?

We’re a remote-first engineering team of 25 people distributed in 14 different countries. A priority for us is maintaining proper work-life balance. We avoid meetings as much as possible, accept deadlines only when absolutely necessary, and never expect anyone to work longer hours than they’ve signed up for. A day in our working lives is pretty boring in this regard, and we feel that’s exactly how it should be.

Working with us means you can be flexible with your schedule. It’s OK to disappear for a few hours in the middle of the day to run some errands, get a haircut, pick up the kids — whatever reason, you don’t need to explain yourself. You also fully decide when you take time off: our team is sufficiently varied and well organized that there are always enough people around to handle the load, and in the rare cases it’s not, we will decrease the load instead of asking people to move their holiday.

Being remote-first means we favor asynchronous communication. We don’t shy away from chatting in Slack, but the important decisions or discussions are done in Gitlab issues, over email, or in our wiki, so there’s a written, persisted record. We’re mindful of maintaining long chunks of focussed time, which means we avoid @-mentions or PMs on Slack, and other triggers and interrupts. We encourage using Slack’s DnD function, especially when you’re not working!

We’d be really happy to welcome you in our #dev channel, but it’s not just virtual: we make sure we regularly get to see each other in real life too. Twice a year we fly the whole engineering team together to a different location in Europe, and at least once a year we join up with the rest of the company so we can spend some time together with the other departments.

What does working at Silverfin look like?

We work in nimble teams around 5 people in size, with each team taking ownership of a specific set of features of the application. Teams are responsible for a full slice across the stack, so both the backend as well as the frontend of each part is maintained by the same people.

You’ll be supported by our UI designer who develops and maintains HTML and CSS components into a reusable UI-framework, and even builds Vue.js prototypes where necessary, handling compatibility problems with different browsers for you, and making sure everything is responsive as well.

Our ops team ensures things run smoothly, deploys happen correctly, and will work with you when issues should arise. We’re enthusiastic followers of the devops mindset, which means ops and developers work together to solve problems, and empower each-other to be self-sufficient, instead of throwing problems over the wall to the “other side”.

Our stack is Vue.js and vanilla JS with a sprinkling of jQuery on the frontend and an up-to-date Rails monolith on the backend. We use PostgreSQL and Redis for persistence and caching, and everything is running on a Kubernetes cluster in Google Cloud. Our daily tools include GitLab, Quip and Slack, with Zoom as our remote conferencing tool of choice.

No code gets deployed without a code-review by a peer and testing is a must. Our pipeline automates deployment when the suite is green, and deploys happen dozens of times a day. Each team is currently doing Kanban, but they’re free to follow whatever process suits them best. There are regular retros held to work towards continuous improvement.

Software for accountants is not considered to be very exciting, but we have our fair share of technical challenges. To give you a sense of scale: our database exceeds 7TB*, and our largest table recently crossed the 10 billion row mark. We interface with more than 30 different external APIs, and provide third parties an API of our own.

*: Our ops team noted that this actually isn’t that hard to achieve if you’re just indexing everything, but it still sounds impressive, right?

What does your future look like?

Personal growth is key to staying motivated. At Silverfin you don’t need to move to management in order to get promoted. We see the individual contributor track and the management track as two different growth paths which every engineer can follow and switch between. You can be promoted, including pay raises, as a contributor just like as a manager.

Everyone has a €1000 yearly budget to spend on conferences, courses, workshops or other training to improve their skills and level up. This also includes accommodation, travel costs. If the conference is on a workday you’ll get paid like any normal day. Silverfin colleagues regularly visit conferences across the world. Are you going to Euruko this year? Come say hi!

We’re looking to hire a lot of new colleagues, and by the end of the year we’d like to have a couple of more teams. Each new team would also need a new teamlead, and we prefer to promote from within the engineering team. This means if you’d like to step onto the management track, there will be plenty of opportunities to do so in the near future. We pro-actively keep track of who would be interested, and provide feedback and learning opportunities to work towards such a goal.

What are we looking for?

  • You’re experienced in both Ruby and Rails, and also understand where the boundaries lie between them. You can code in Ruby without any of Rails’ training wheels if necessary.
  • You’re up for mentoring coworkers and can give in-depth, productive feedback during code reviews. While you appreciate the small stuff, you recognize bikeshedding and can avoid its pitfalls.
  • You code with reason and can justify the important decisions you made during development.
  • You can communicate clearly in English, both written and verbally.
  • You know and can apply best practices when relevant. That means the usual like version control, testing, and refactoring; but also higher level concepts such as good object oriented design.
  • You're aware of the trade-offs involved in proper engineering and can make balanced business decisions, keeping in mind all the stakeholders of the project.
  • You’ve got opinions on code design and you can discuss them, but you’re professional enough to not let those opinions get in the way of a consensus if necessary.

What can we offer you?

  • Actual, proper work-life balance
  • Choose your own working hours and work 100% remotely
  • Personal growth training and opportunities
  • Join a distributed remote-first engineering team with 25 colleagues in 14 different countries
  • A refreshing work environment with professional, friendly and welcoming colleagues
  • A €1000 yearly budget for conferences, courses, workshops or other expenses that will improve your skills

Requirements

  • You have at least 4 years of experience working with Ruby, or 2 years of experience with Ruby and 4 years in other languages.
  • You get Rails
  • Your work hours have some overlap with EU business hours (we require your local timezone to be within CET +/- 3h)

Nice to have’s

These would be nice but are definitely not necessary. Don’t worry if none of the following applies to you.

  • Experience as a remote worker in a fully remote team
  • Experience with Javascript (ES6) and frontend frameworks
  • Experience working with large datasets and the problems they bring
  • Experience in Fintech
  • Accounting knowledge

  • Remote Anywhere
  • Full-time

July 8, 2020

This job post is over 30 days old. It's very likely the position is already filled.
Try applying to a more recent job post instead.

We’re looking for talented individuals interested in joining a new and growing global company. At Slang, you’ll be an early team member of a well-funded startup spun out from MIT. We’re building a world-class team to revolutionize language learning with cutting-edge technology and beautiful design.

What we’re working on at Slang

Slang started at MIT as a research project on using AI and NLP to make learning a new language as efficient as possible. Our technology powers a highly adaptive e-learning platform that offers an unprecedented variety of specialized English courses and proficiency tests for career development in over fifty fields like Sales, Finance, Logistics, Medicine, and Law. With just a small team, we’ve already created the largest professional English offering in the world. Now, we’re scaling up to release 1,000 more courses over the next three years.

Learn more about our unique approach at slangapp.com. We’d love to field any questions you have about our product and vision!

What this role is about

If you’re interested in pioneering a way to apply cutting-edge technologies to online education, we would love to tell you more about our opportunity.

In this role, you’ll be involved in both product development and company strategy and execution — you’ll own the research, design, and development of the back ends of new features and you’ll help us refine our product roadmap. We have tens of thousands of active users and many subproblems in language learning to tackle.

As a senior-level member of the team, you will also have the opportunity to step into a technological leadership role as our Engineering Team grows over the next year. There is room at Slang for both technology-focused and management-focused senior-level engineers; a career path which best suits your own professional goals will be established.

In addition to day-to-day engineering needs, technology-focused senior engineers will be responsible for architecting full solutions to complex technological problems and establishing best practices for our engineering processes. Management-focused senior engineers will be responsible for mentorship of junior engineers, recruitment, and structuring the growth of Slang’s Engineering Team. All senior-level engineers play a strong role in code review and coaching.

Our codebase is built with best practices in mind and our product is designed with proper user and developer experience at the forefront of development. The work we’re facing encompasses interesting infrastructural hurdles and data-heavy modeling and algorithmic tasks.

Some of our technology comes from the open-source community, so be prepared to contribute back!

Some interesting problems we’re tackling:

  • How can we determine what parts of a language a user already knows from a small sample of test exercises? How should we decide which parts of a language a user should learn next? How can we answer these questions quickly?

  • How should we architect our database to support the growing number of activities our users submit every week (currently at more than a million per week)?

  • How can we aggregate and communicate the learning statistics of a company’s employees for display to their managers?

  • How can we analyze and leverage the massive amount of learner and content data we have to improve our learners’ experience?

Skills and technologies

  • Five or more years of experience in modern back-end web development, including:

  • Extensive experience with modern web API stacks and related technologies, with a preference for Ruby on Rails and/or Java experience.

  • Extensive experience with database technologies, data structures, and related optimization. We currently deal with large amounts of data in PostgreSQL and Redis.

  • Experience in engineering leadership roles, perhaps in a position like “tech lead” or “engineering manager.”

  • A strong desire to maintain a clean, reliable, maintainable, and efficient codebase.

  • Excellent discipline and focus, especially in autonomous environments, and strong English communication skills. We’re a small team and we’re moving quick!

  • A plus: interest or experience with computational linguistics, natural-language processing (NLP), language-learning, speech recognition, data science, or machine learning.

To make things easy, include your résumé, GitHub username, and/or a short description or link to something you’ve worked on that’s software- or tech-related. Perhaps a Ruby gem or an interesting data-science paper — surprise us!

Slang is an equal-opportunity employer. We celebrate diversity and are excited about creating an inclusive and healthy environment for all employees.

What Slang can offer you

Our compensation package includes a competitive salary and unique benefits.

Most importantly, we offer the special experience of being part of a fast-moving and quickly growing international company within the entrepreneurial ecosystems of Boston and MIT.

Where we're located

Wiki Education Software Developer
  • Remote Anywhere
  • Full-time

May 15, 2020

This job post is over 30 days old. It's very likely the position is already filled.
Try applying to a more recent job post instead.

As Wiki Education’s Software Developer, you will work with our Chief Technology Officer to build and maintain the Wiki Education Dashboard, an open source web app built with React and Ruby on Rails that empowers thousands of instructors, librarians, and others across the globe to organize newcomer-friendly Wikipedia editing projects and track the contributions of these new Wikipedians. You’ll create new features that help people do more and better work on Wikipedia, Wikidata, and other free educational projects. You’ll talk with the Wiki Education staff, instructors, and students who rely on your work. You’ll fix bugs, solve user experience problems, make accessibility improvements, and remove performance bottlenecks. You’ll contribute patches to the upstream projects we depend on. You’ll provide technical mentorship to interns and volunteer code contributors. You’ll refactor, write tests, monitor deployments, and ensure that we maintain a livable, newcomer-friendly codebase. Sometimes you’ll pair program, or work on WordPress and Salesforce, or use any of a wide variety of technical tools in the wider Wikimedia ecosystem. With the rest of the Wiki Education team, you’ll help make Wikipedia a more reliable and comprehensive resource for the millions of people across the world who rely on it every day.

Background

Wikipedia is an incredible community and a valuable educational resource. But the experience for new users has fallen behind, holding back Wikipedia’s potential to achieve its goal: a world in which every single human being can freely share in the sum of all knowledge. There remains a large gap between traditional knowledge institutions — universities, libraries, archives, museums — and Wikipedia. Wiki Education’s mission is to bridge that gap, finding ways to bring new contributors and new knowledge to Wikipedia. As a small nonprofit with a technology stack outside of Wikipedia’s own legacy infrastructure, we have the freedom to experiment with new ideas, iterate quickly, and tackle big problems. We’ll build great free and open source technology, nurture a vibrant development community, and — if we can pull it off — save Wikipedia by supporting the next generation of contributors.

Minimum qualifications

  • Excellent communication skills
  • Strong frontend JavaScript skills
  • Strong HTML and CSS skills
  • Experience with React
  • Experience with Ruby on Rails

Bonus qualifications

  • Experience deploying and scaling Rails apps
  • Experience maintaining open source software projects with many contributors
  • Experience mentoring junior developers
  • Visual and UI design expertise
  • i18n and/or a11y expertise
  • Salesforce configuration experience
  • Experience with payment systems
  • WordPress development experience
  • Wikipedia editing experience
  • Familiarity with the US higher education system

About the position

We’re open to candidates with a range of experience levels. The ideal candidate will be a senior-level developer with extensive experience designing and building modern web applications; junior- and mid-level developers with a strong foundation in JavaScript and Ruby will also be considered. The position is full-time and remote.

Trips to San Francisco for Wiki Education all-staff meetings are required twice per year. Applicants must be legally authorized to work in the United States.

Salary

$80,000 – $110,000 (depending on experience), with generous benefits
