Senior Backend Engineer - Team Decide

What You'll Do

• Build and operate backend services in Python on AWS — Lambda functions, DynamoDB, Aurora, and event-driven pipelines that handle real production traffic. You'll leverage agentic AI tools as part of your daily workflow. - Tackle hard backend problems — latency, reliability, and scale are everyday concerns. - Own your systems end-to-end: from architecture and implementation to deployment, monitoring, and incident response. - Make key architectural decisions — you'll have real authority over how things are built, not just what gets built. - Raise the bar for the team through code reviews, mentoring, and improving our development tooling and processes. - Work directly with Product and Design to shape what we build next. ## Requirements

• At least 5 years of professional software engineering experience, with a proven track record of leading complex projects in a senior capacity (2+ years). - Deep expertise in Python and building backend systems on cloud platforms (we use AWS). - Strong system design skills — you're comfortable making architectural trade-offs and defending them. - Depth in at least one of these areas: data pipelines and storage, event-driven architectures, caching and performance, or serverless systems. You don't need all of them. - Strong communication and collaboration skills, with the ability to align technical and non-technical stakeholders on a shared vision. - The ability to work in a hybrid model from our Berlin HQ, the London office, or the Iasi hub. Please note that relocation assistance is not provided for this role. ##
