• Make pragmatic decisions about trade-offs (scope, performance, scalability, security) in a fast-moving environment.
• Act as the day-to-day technical and delivery lead for a squad of engineers
• Define and manage the work: break down Product Requirement Documents and user stories into clear tasks, estimate effort, set priorities and timelines, and track progress to ensure on-time delivery.
• Run or participate in ceremonies (stand-ups, planning, reviews) to keep work aligned and unblock issues quickly.
• Take ownership of complex or high-impact pieces of work, especially where the architecture, integrations or performance considerations are non-trivial.
• Design, build and optimise the journeys of our service using our tech stack: Backend: Python Frontend: React + Flutter Data / Infra: Postgres, AWS (S3, ECS etc.)
• Write high-quality, testable code and contribute to our continuous integration and deployment pipelines.
• Take ownership of technical design as part of a small, fast-moving team.
• Help evolve our platform architecture for performance, resilience, observability and security as we scale.
• Identify and drive improvements to developer experience, tooling and internal processes (e.g. testing, release, monitoring, on-call), in collaboration with both in-house and outsourced engineers.

Requirements

• Degree in Computer Science or related developer education (e.g. a reputable coding bootcamp) or equivalent practical experience.
• 7+ years’ experience designing, developing, shipping and maintaining backend applications using Python and front-end web applications using modern JavaScript frameworks (ideally React.js), including operating at lead level.

• Experience of working with continuous deployment pipelines (you don’t have to build everything yourself, but should be comfortable working within and improving such setups).
• Strong understanding of industry trends and development best practices – especially regarding security, application performance and scalability.
• Has a strong sense of ownership, attention to detail and the ability to work independently with a team-oriented work ethic.
