Our super-duper Engineering Team lies at the core of the value we offer to our customers. We solve complex problems by working not only within our squads, but also by collaborating with other teams across the organization. If you are excited by solving complex technical challenges, this is the right place for you!

WHAT YOU'LL DO

As a Fullstack Engineer, your technical knowledge and autonomy will let you build complete designs for our applications and features.

• Designing and implementing intuitive user interfaces to collect and review information.
• Building and maintaining robust APIs that automate decision-making processes.
• Writing, testing (from unit to end-to-end), and delivering clean, maintainable code.
• Actively participating in releases, deployments, and monitoring of solutions in production.
• Contributing to technical migrations, modernization efforts, and architectural improvements as our platforms evolve.

Performance, scalability and quality are key challenges to solve in order to deliver and review code. You are part of a team and collaborate with your teammates (software engineers, data scientists, QA, UX, product managers) to constantly receive and give feedback and improve the agile development process.

We work with modern technologies and always encourage our team to explore what’s new in the market. Our main tools are:

• Frontend: React/Redux/TS/Vanilla Extract/LESS/Dev Container with Vite
• Backend: ASP.NET, C#, Java, MSSQL, Elasticsearch

• Cloud: Microsoft Azure
• Foundational toolchain: GitHub Enterprise, GHAS, GH Copilot + coding agent
• CI/CD: GitHub Actions / TeamCity, Cypress, GH Packages (npm, NuGet), Octopus
• Collaboration: Slack, Jira, Confluence

WHO YOU ARE

• You have a first experience as a Software Engineer, at least as an apprentice
• Backend wise, you have used C# and Java - it's a MUST!
• You have some Frontend experience as well - any framework works; we work with ReactJS!
• You are a true Fullstack: Frontend is part of your job, as much as Backend!
• Your projects are beautifully designed and cleanly written
• You are dynamic, curious and eager to learn, always looking to expand your fields of expertise
• You are proactive and take ownership of your work
• You want your work to have an impact: rather than a cog, you see yourself as the engine
