## Description

Senior Backend Software Engineer / Developer (Python) London / WFH to £120k

Are you a technologist with start-up experience looking for your next opportunity?

You could be progressing your career at a tech start-up that is producing an AI native data pipelining platform.

As a Senior Backend Software, you'll own the orchestration engine that controls scheduling, execution, state, retries, concurrency and cancellation, using Python, FastAPI and AWS in a high velocity production environment. You'll design for unpredictable workloads, solving challenges around capacity, back pressure and isolation, while building the AI native layer that will underpin the next generation of the product.

You'll own your infrastructure end-to-end, writing Terraform, monitoring what you ship and resolving issues in production. Working across the full development lifecycle, you'll take features from idea through to production, collaborate directly with customers to solve complex real-world problems and use your technical insight to influence the product roadmap. As part of a small, ambitious engineering team, you'll also have a genuine opportunity to shape engineering standards, culture and ways of working.
