About the role

• Senior Backend Engineer developing backend services in Python for fintech startup. Building systems that automate credit and risk decisions for banks and fintechs in real time.

Responsibilities

• Build and operate backend services in Python on AWS - Lambda functions, DynamoDB, Aurora, and event-driven pipelines that handle real production traffic.
• 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.

• 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.

• Learn from experienced mentors and achieve tremendous personal and professional growth.
• Receive a top-of-market equity and cash compensation package.
• Get access to a self-development budget you can use to e.g. attend conferences, buy books or take classes.
• Receive a new Apple MacBook Pro, as well as meaningful home office set-up.
