Role summary: A product-minded senior frontend engineer who thrives in fast-growth environments, owns features (and their quality) end-to-end, and uses agentic development workflows to ship faster. Works closely with product and design, not just executing tickets.
Responsibilities:
- Work closely with the Product team to build out core applications for both internal and external users.
Evaluation criteria (in priority order):
- Fast-growth / high-performance startup or scaleup experience (highest weight) - Has worked at a Series A/B (or comparable) startup through a period of rapid scaling, ideally not just a large, stable org. Comfortable with ambiguity, shifting priorities, and shipping under pressure without over-engineering. Signals: early/founding engineer roles, "first N engineers," ownership of significant surface area, demonstrable velocity. Be wary of CVs showing only big-company or agency/consultancy backgrounds.
- Strong agentic workflows / development optimisation - Actively uses AI coding agents (Claude Code, Cursor, etc.) as a core part of how they work, not as an occasional aid. Thinks about optimising their own and the team's development workflow - tooling, automation, spec-driven development. Signals: mentions of agentic/AI-native development, internal tooling, DX improvements, side projects built with agents, relevant OSS contributions (MCP, agent frameworks). Recency matters - this should be current, not aspirational.
- Strong product engagement / design collaboration - Engages with the "why," contributes to product decisions, and pushes back constructively rather than waiting for fully-specced tickets. Collaborates directly with designers; comfortable with Figma handoff and translating design intent into polished UI. Signals: product-led teams, mentions of shaping features, user-facing ownership, design-system or UX-quality work.
- React experience - Solid, current production React. Adjacent modern stack (TypeScript, Next.js) is a plus. Note: lowest-weighted of the ranked criteria - a strong agentic, product-minded scaleup engineer with a slightly different framework background may still be worth considering.
Ownership of quality (baseline expectation): Used to owning their own testing and quality - writes and maintains their own tests, doesn't rely on a separate QA function to catch issues. Signals: TDD/testing discipline, mentions of test coverage ownership, "you build it, you run it" cultures.
Disqualifiers / flags:
- Cannot commute to London.
- Purely backend or infrastructure focus with no frontend ownership.
- No evidence of any of the top three criteria.
