Salary DKK50,000 - DKK65,000
Equity To be negotiated
JOIN OUR TEAM IN COPENHAGEN OR ODENSE! Abtion is a creative technology company with over 10 years of history delivering of great products to clients. Abtion builds mobile apps, websites, and hardware projects with a purpose on daily basis. Our team is at the core of everything we do and what ultimately leads to our success in innovating for clients.


We’re looking for engineers who like dynamic client/agency projects, and who write and maintain extensible, well-tested code that can be easily handed off to customers. You are a great fit because you are kind, enjoy dialog, and have spent 5+ years as a developer. You have a strong understanding of some of our technologies, and have prior experience working with legacy code bases. You care about the end user of the product as much as the developer who will work on your code next. You don’t need to have a degree, or to have worked with all of our technologies before. If you’re strong with ruby/rails OR javascript, that is ok.


As a senior software engineer, you will help us lead projects for clients from Maersk to Lego to Sennheiser. You’ll also be helping to shape our daily process and work: test driving new features, pairing on refactor code, helping our sales team to scope the work that is scheduled, collaborating with designers to produce mocks that are technically informed, mentoring junior engineers, and experimenting with new technologies.


Most often, you will see a backend rails api paired with react or react native. We make extensive use of Ruby/Rails, Javascript, AWS, Heroku, Docker, Postgres, Redis, CircleCI, New Relic, Rspec, and Jest. We also have some growing interest in infrastructure as code.


We like to keep it as short as possible while also getting to know each other. We expect to spend about 16 hours on you, and you to spend 8 hours on us.

  1. Initial Meet - coffee or phone chat to see if there’s mutual interest

  2. Basic skills & Career desires - 1.5 hour pairing session or take home task and conversation about your career

  3. Lunch & Coding - 3 hr morning or afternoon working with a real team

  4. Recap - exchange feedback with us
