Senior Python Developer

Responsibilities

• Design, build, and operate Python services and APIs that carry production traffic, with performance, reliability, and security as first-order concerns rather than afterthoughts.
• Own data pipelines end to end: ingestion, transformation, validation, and the monitoring that tells you when something has gone wrong before a partner does.
• Make architecture decisions and defend them. You will be the person in the room with the strongest opinion on how a system should be shaped, and you will be expected to have one.
• Build AI-assisted features into internal and customer-facing products where they earn their place, working with LLM APIs, retrieval, and structured extraction.
• Review code with real rigor, and raise the standard of the code around you by doing it.
• Diagnose production issues under time pressure, fix the cause rather than the symptom, and write down what happened.
• Mentor mid-level engineers and give them the context to make good calls without you.
• Work as part of our Ukraine-based Python team, taking technical direction from their lead and coordinating daily on sequencing, code review, and handoffs.
• Work directly with product, data, and operations partners to turn a business problem into a scoped technical one.
• Working with AI
