About the Role

We are looking for a passionate Engineer to join our cross-functional squad in London. While the role has a strong front-end focus, we are an AI-first engineering organization. The ideal candidate uses agentic AI tools as a force multiplier and is comfortable flexing to tackle backend tasks (Kotlin/Spring) when squad priorities shift.

Responsibilities

  • Build, test, and optimize highly scalable, user-oriented features for our client-facing web application.
  • Take ownership of domain software, contributing to our event-driven microservices platform when backend support is needed.
  • Leverage agentic coding tools (e.g., Claude Code) across the full development lifecycle, reviewing and hardening AI-generated outputs to maintain rigorous quality standards.
  • Collaborate in a two-week delivery window to plan, develop, and release secure, cost-efficient features.

Requirements

  • 3+ years of experience as a front-end engineer utilizing JavaScript/TypeScript and the React library.
  • Daily practical experience with AI-assisted or agentic development tools, with the engineering judgment needed to audit and refine AI outputs.
  • Familiarity with TDD principles, clean architecture concepts, and consuming APIs (e.g., GraphQL).
  • An independent, critical thinker who thrives in collaborative, small-team environments and values continuous feedback.
  • Backend development experience in Java or Kotlin (ideally Spring Boot).
  • Understanding of microservices, database concepts (RDBMS/PostgreSQL), and event-driven architectures (Kafka).
  • Familiarity with containerization (Docker) or cloud deployments (AWS/Kubernetes).
