Jobbeschreibung

We’re expanding our existing team for one of our core products at Shiftmove, and we’re looking for one talented Senior Software Engineer focusing on the backend to join us!

You will join a cross-functional team working on one of Shiftmove's most critical and complex products: the Logbook. The team focuses on maintaining, improving, and evolving a mature, large-scale system with many dependencies across mobile, web, and internal tools. You will collaborate closely with backend, frontend, and mobile engineers, product management, design, and engineering leadership to continuously improve system quality, reliability, and clarity.

If you’re thoughtful, collaborative, and eager to grow then we’d love to meet you!

What You Will Do

• Design and evolve backend systems and architectures to improve scalability, reliability, and long-term maintainability
• Analyse complex, legacy-heavy systems to identify risks, bottlenecks, and opportunities for simplification
• Develop and refine backend services and APIs with a strong focus on correctness, performance, and code quality
• Challenge technical assumptions and proposals by evaluating trade-offs and offering well-reasoned alternatives
• Drive technical initiatives that reduce complexity, improve system foundations, and increase team effectiveness

OUR TECH STACK

• Backend: Python, Flask, FastAPI
• CI/CD: AWS CodePipeline/CodeBuild
• Cloud: Amazon Web Services
• AI: TensorFlow, Python, SpringAI, Gemini

YOUR PROFILE

• You have meaningful experience designing and evolving systems and making architectural trade-offs around performance, cost, and maintainability.
• You write clean, testable, and maintainable code and are comfortable working in large, existing codebases.
• You apply strong analytical and critical thinking to break down complex problems, identify edge cases, and assess risks before implementation.
• You confidently challenge assumptions and use data, logs, or system insights to support your decisions and recommendations.
• You lead by example through influence, mentorship, and clear communication rather than formal authority.

Why should you join us?

• Real impact: work on products used by thousands of customers across Europe.
• Engineers get a top-spec laptop, using the platform of their choosing
• Mental health support: access to Nilo.health platform if you could use a session with a psychologist.
• 30 paid vacation days per year + 1 mental health day
• 12 weeks of remote work from any country or continent you want!
• The choice of a range of Company Benefits, such as an Urban Sports Club membership, JobRad, or a BVG ticket grant
• Hybrid setup: 2 days/week in our Berlin office, flexible remote options otherwise.
• A dog-friendly office and plenty of flexibility to take care of what matters most
