We’re looking for a Senior Backend Engineer to join our MAT – Backend (Main Application Team). In this role, you’ll play a key part in designing and evolving the backend systems that power Rossum’s core product, supporting complex document processing workflows and data flows used by customers at scale. This role goes beyond implementation; our engineers knew that technical debt and scalability were problems we needed to solve, and we’re looking for you to help shape those solutions. You’ll work closely with Product, Frontend, and other Backend teams to deliver features that balance immediate needs with long-term maintainability.

The atmosphere here pushes you to explore things, to think – quality really matters here. We're all geeks who go home after work and keep coding on our own stuff, and there’s this cool Silicon Valley garage culture. People don’t leave Rossum to join MasterCard – they leave to build their own things, and I think that’s really cool.
What You'll Do
You will be a critical contributor to our backend efforts, managing day-to-day operations while identifying strategic improvements to keep our systems reliable and easy to build on.
Key responsibilities include:
- Design, implement, and maintain backend services and APIs in Rossum’s core platform.
- Take ownership of larger backend features or components from initial design through to production.
- Write high-quality, well-tested code with a constant focus on scalability, reliability, and security.
- Partner across departments, participating in code reviews to offer constructive guidance and collaborating with Frontend and Product teams.
- Proactively identify and address performance, reliability, and operational issues to drive technical excellence.
The Rossum team embraces challenges to the status quo and possesses a strong aptitude for rapid learning. We are continually advancing in technology, and the optimal path for our growth evolves year after year.
Who You Are
We’re looking for a peer who is a "bullshit-free" problem solver and isn't afraid to challenge assumptions. You should bring:
- Strong professional experience in backend engineering within a production environment.
- Advanced knowledge of Python (or a similar backend language) and a solid understanding of relational databases.
- A balance of hands-on execution and strategic thinking, specifically in designing REST APIs and operating backend services.
- Experience with AI coding tools and a proven track record of owning features through their full lifecycle.
- A proactive and empathetic approach to communication and cross-functional collaboration.
- Bonus points for:
- Experience with distributed systems, messaging, and cloud-based architectures.
- Familiarity with Docker, CI/CD pipelines, or infrastructure tooling.
- A passion for mentoring junior engineers or acting as a technical point of contact.
What Success Looks Like
- Within 3 Months: You’ll build a strong understanding of our backend architecture and start delivering changes independently as a reliable contributor to the team.
- Within 6 Months: You’ll own larger features end-to-end and begin improving existing systems through refactoring or performance tuning.
- Within 12 Months: You'll act as a go-to engineer for specific backend areas, helping shape technical direction and raising the engineering bar across the MAT team.
What we offer
- Creative Work - Engage in innovative projects where your ideas and solutions can make a real impact. We value creativity and encourage out-of-the-box thinking.
- Diverse Responsibilities - Enjoy a variety of tasks that keep the job interesting and challenging. You'll have the opportunity to work on different aspects of our infrastructure and continually learn new skills.
- Small but Active Team - Be part of a small, dynamic team where everyone's contributions are significant. You'll work closely with passionate and driven colleagues in a collaborative environment.
