We start with the cliff notes about the position. If this appeals to you, continue reading for a longer text about working at Silverfin and your role ð

At Silverfin, we're an equal opportunity employer and value diversity at our company. Although we know weâre not perfect yet, we are working hard on it and always open for your feedback.

According to our vision to build a diverse, equitable and inclusive organisation, our policy is to only make a final hiring decision once underrepresented underrepresented groups are sufficiently reflected in the list of candidates applying for the position. For this reason itâs possible interviews get slightly delayed until weâve reached that goal.

We're committed to elevating talent by creating an environment where we can all thrive together. So if you think you have what it takes, but don't necessarily check every single box, please consider applying. We'd love to hear how you might contribute to our mission and our team.

What can we offer you?

  • Actual, proper work-life balance

  • A salary range of â¬88.000 - â¬120.000 a year

  • Employee Stock Option Plan

  • Flexible working hours and possibility to work 100% remotely

  • Experienced engineers as mentors 

  • Personal growth training and opportunities

  • Join a distributed remote-first engineering team with 35 colleagues in 14 different countries on 2 continents 

  • A refreshing work environment with professional, friendly and welcoming colleagues

  • A â¬1000 yearly budget for conferences, courses, workshops or other expenses that will improve your skills

  • Two engineering retreats per year, somewhere in Europe 

  • For the third year in a row, we offer monthly company-wide Wellbeing Days for all employees (once a month in 2023, except in July and August)

What will you work on?

  • A production SaaS application used by thousands of customers on a global scale.

  • The best ways to solve a customer or business problem in close collaboration with a product manager, a product designer and other engineers 

  • User facing functionalities 

  • Maintenance, support and bug fixes of existing functionality

What are we looking for?

  • Youâre experienced in both Ruby and Rails, and also understand where the boundaries lie between them. You can code in Ruby without any of Railsâ training wheels if necessary.

  • You have some experience using Javascript framework(s), understand the value of them, but also know when plain Javascript is enough.

  • You're interested in getting to know our customers to find the best solution for a given challenge. 

  • You code with reason and can justify the important decisions you made during development.

  • You can communicate clearly in English, both in writing and verbally.

  • You know and can apply best practices when relevant. That means the daily tools of the trade 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.

If youâre any good at Ruby, this is probably not the first job ad youâve seen, so weâve done our best to stand out while also accurately presenting what weâre all about. If it sounds like you would enjoy working with us, donât hesitate to apply or drop us a line with questions on [email protected].

Whatâs a Silverfin?

At Silverfin weâre trying to apply the promise of software to the age-old industry of accounting. With our SaaS weâre 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 optimise 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 weâre succeeding in doing exactly that. Every week more than 15.000 financial service professionals use Silverfin to help and advise more than 400.000 businesses. Our customers adore us! The even better news is thereâs still plenty left to work on, and thatâs where we hope you come in.

What does working at Silverfin look like?

The Silverfin engineering team consists of two main types of teams. A product team is a cross-functional team where engineers work together closely with product managers and product designers. The team's input comes from users or from a business problem that it can solve with a high degree of autonomy. Product teams are supported by a handful of platform teams that focus on the application's architecture and stability, while providing internal tooling and APIs.

Our ops team ensures things run smoothly, deploys happen correctly, and will work with you when issues should arise. Weâre 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 âother sideâ.

We run an up-to-date Rails monolith on the backend, with 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 theyâre 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 10TB*, and our largest table has crossed the 10 billion row mark a long while back. 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 isnât that hard to achieve if youâre just indexing everything, but it still sounds impressive, right?

What makes the engineering team at Silverfin special?

Weâre a remote-first engineering team of 35 people distributed in 14 different countries over two continents. 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 theyâve signed up for. A day in our working lives is pretty boring, and we feel thatâs exactly how it should be.

Working with us means you can be flexible with your schedule. Itâs 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 donât need to explain yourself. You also fully decide when you take time off: our team is sufficiently varied and well organised that there are always enough people around to handle the load, and in the rare cases itâs not, we will decrease the load instead of asking people to move their holiday.

Being remote-first means we favour asynchronous communication. We donât shy away from chatting in Slack, but the important decisions or discussions are done in Gitlab issues, over email, or in Quip, so thereâs a written, persisted record. Weâre 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 Slackâs DnD function, especially when youâre not working!

Weâd be really happy to welcome you in our #engineering channel, but itâs 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 your future look like?

Personal growth is key to staying motivated. Our team of experienced engineers is there to mentor you and help you hone your craft and improve as an engineer. You will have a chance to get to know and work with a state-of-the-art software development workflow on a real life Rails app at a large scale..

It's also good to know that later on at Silverfin you donât need to move to management in order to advance. 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 or as a manager.

Everyone gets a â¬1000 yearly budget to spend on conferences, courses, workshops or other training to improve their skills and level up. This also includes accommodation and travel costs. If the conference is on a workday youâll get paid like any normal day.


  • You have at least 2 years of experience working with Ruby, or 1 year of experience with Ruby and 3 years in one or more other programming languages

  • Your work hours have some overlap with EU business hours (we require your local timezone to be within CET +/- 3h)

  • You can communicate clearly in English, both in writing and verbally

Nice to haves

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

  • Experience as a remote worker in a fully remote team

  • Experience working with large datasets and the problems they bring

  • You have some experience using Javascript framework(s), understand the value of them, but also know when plain Javascript is enough

  • Experience in Fintech

  • Accounting knowledge


You can apply today and weâll start having interviews from 11/09. Thereâs no benefit to applying early, so you can take your time answering the application questions.
