Senior Backend Engineer

Depending on your preferences and skill sets you either work solely on the backend or in the full stack but for this role we put a lot of emphasis on the backend side.
As a senior engineer, we believe one of your priorities will be to enable your junior/mid level colleagues to grow. This means you will spend time on things like coaching, leading/facilitating code reviews and pair/mob programming sessions, onboarding new engineers and holding/facilitating workshops/sessions around areas such as code quality, refactoring, performance, testability and working with tests and service-oriented architecture.
With your experience, you will bring a long-term perspective to building software and while implementing new features you will keep in mind the long-term stability of our system and the quality of the code. You understand, and can advocate for, the need to choose the right tool for the job in question rather than pushing for one size fits all.
You will try to strike a good balance between discovery and implementation work, between new customer facing features and managing tech debt and technical initiatives.
Since Employee Experience (also known as Developer Experience) is very important to us, we hope that you will raise your voice by influencing which tools, programming languages, and technologies you work with while helping us ensure we have a smooth software pipeline for continuous and fast delivery.


Skills & Requirements
We believe you have at least five years of experience as a full-stack or backend developer, mainly in web development.
If you are not already comfortable with Ruby, we believe you have a solid history in one or several other languages such as perhaps .NET, Java, Python or node.js. Your current language of choice is not as important as a passion to learn but Ruby would definitely be a plus.
We believe you agree with us that upskilling others is a core task for a senior engineer and hopefully you have a history of mentoring others. Another important way of upskilling others is through knowledge sharing. We would love it if you want to do this in some way. Maybe you like writing blog posts and/or articles, maybe you prefer public speaking or maybe you are more comfortable facilitating internal knowledge sharing sessions. Or perhaps you take a more hands-on approach and prefer 1:1 technical mentoring.
In addition to being a good cultural fit (see below), we hope that you bring a passion for software development, scalable architecture and building great products. For us, is it important that everyone cares about code quality so an interest in testing and automation is needed. Excellent communication skills and being able to work both independently and in a team are some other traits we are looking for in all of our colleagues.
Last but not least: Having a curious mindset, being open to learn & share knowledge and of course: that you are interested in working with our tech stack.
