Job technologies

Your role in the team

  • We are looking for a Backend Engineer (5+ years of experience) to join our Assess engineering team, building secure, scalable financial products.
  • You will work directly alongside our other engineers to own, build, and scale our Assess backend infrastructure and product offering from the ground up.
  • While your primary strength and passion lie in backend systems (Python, Go, and Kubernetes), we value a pragmatic, product-driven mindset.
  • You should be comfortable occasionally jumping into our React frontend when needed to get features over the line, even if backend is where you do your best work.
  • Co-own the entire back-end stack: Design, build, and maintain our core microservices in Python and Go.
  • Leverage AI-first workflows: Use AI-first development workflows to act as a force multiplier, moving fast without sacrificing code quality.
  • Focus on creating detailed plans for agents to execute rather than writing code directly.
  • Use your technical and analytical skills to evaluate the outcome and ensure that the generated code meets all requirements.
  • Own our infrastructure: Manage, deploy, and scale our services using Kubernetes, ensuring high availability and system reliability.
  • Collaborate on product & architecture: Partner directly with the team to make rapid architectural, tool selection, and product roadmap decisions.
  • Optimize for speed and security: Build fast, but maintain the high security and compliance standards required for financial systems.
  • Wear multiple hats: Run DevOps, monitor production systems, and occasionally work on the React/TypeScript frontend to unblock feature releases.

Our expectations of you

Qualifications

  • Deep, production-level expertise in Go and/or Python (comfort switching between both is key).
  • AI Tool Fluency: Highly proficient in leveraging AI-first coding workflows to maximize your output and troubleshoot rapidly.
  • Product-oriented, 'founder' mindset: You care about the user and the business, not just the code.
  • You know when to build a perfect system and when to ship a scrappy MVP.

Experience

  • 5+ years of experience building and scaling production-grade back-end systems.
  • Hands-on Kubernetes experience: Ability to set up, debug, and manage containerized environments independently.

What we offer

  • Impact & Ownership: An environment where your ownership is valued and strengthened.
  • Flexibility: A modern, hybrid working model across our Berlin and Munich locations.
  • We work in a hybrid setup, with a strong focus on teamwork and efficient collaboration.
  • Personal growth: We support your development with a personal budget, semi-annual feedback, and clear growth paths.
  • Pioneering spirit: Become part of a team with genuine passion for the future of open banking.
