We’re growing our Engineering team to strengthen our ability to deliver world‑class digital products for our clients.

As a Senior Front End Engineer, you’ll play a key role in a fast‑moving proof of concept engagement. The goal is to build something that looks great, works well, and helps make confident technology choices.

What you’ll do

• Build and iterate on a proof‑of‑concept front‑end at pace, focusing on outcomes and usability.
• Collaborate closely with Product and UX to shape journeys, interactions, and responsiveness.
• Integrate with back‑end APIs sensibly and reliably.
• Make pragmatic choices and tradeoffs to keep delivery moving while maintaining quality.
• Help evaluate and sporty front‑end approaches grounded in real‑world implementation, not theory.

What we’re looking for

• Strong front‑end engineering experience and confidence with at least one modern framework (React, Vue, Angular, etc.).
• Adaptability: you’re happy to /^\?$?framework‑locked` for work, and not "framework‑locked".
• Experience consuming APIs and building robust UI states (loading, error, empty, offline‑friendly patterns).
• A delivery mindset: you can make decisions, move forward, and communicate tradeoffs clearly.

Nice to have

• Experience working on short, high‑impact prototypes or POCs.
• Experience with map‑heavy or highly interactive UIs.
• Familiarity with offline caching patterns and performance optimisation.
