Senior Backend Engineer, UK

Drive Technical Direction: Design and ship moderate to complex backend features with minimal guidance, making pragmatic choices between modular-monolith code, shared components, or independently operated services.

Raise the Bar: Advocate for product quality, security, availability, and performance. You will define backend standards for style, maintainability, testing, APIs, and operational readiness.

Mentor & Lead: Mentor associate and intermediate engineers, remove technical blockers, and improve team delivery practices through code and design reviews.

Operational Excellence: Diagnose and prevent performance/reliability issues at scale. Participate in incident response and act as a technical owner where appropriate.

AI Integration: Use AI in production engineering work to improve outcomes, evaluate its effectiveness, and coach others on responsible, high-judgment use.

Deep Backend Expertise: A strong command of backend architecture, APIs, data systems, and performance tuning in a complex product or service environment.

Adaptability: Proficiency in modern backend languages and a deep understanding of systems programming. We value the ability to learn and adapt over mastery of a single language.

Architectural Judgment: Experience designing or evolving modular backend boundaries, bounded contexts, and migration-safe architectures.

Influence: Ability to lead through influence, technical judgment, and clear written communication, effectively bridging the gap between product needs and technical reality.

Agentic AI Expertise: Proven experience building or operating agentic systems in production—moving beyond prompt engineering to architecting loops, tool-use, and error-handling strategies that ensure reliability at scale.

Experience with high-throughput distributed systems, concurrency, or profiling.

Hands-on experience with containerized production operations (e.g., Kubernetes).

Deep database performance knowledge (e.g., PostgreSQL, ClickHouse, schema evolution, partitioning).

Background in large-scale modular monoliths or event-driven systems.

Public technical communication, open-source maintenance, or experience in developer-focused SaaS.
