Join a small, senior product engineering squad at an AI‑first company building a B2B marketplace for second‑hand clothing. As a Senior Full‑Stack Engineer you’ll primarily focus on front‑end, driving user growth and core consumer experience through web and mobile.
The work
- Own end‑to‑end delivery of user‑facing features across web and mobile, directly impacting GMV, activation, and retention.
- Rebuild core product experiences from first principles: item discovery, search, buying flows, and post‑purchase.
- Design, run, and analyse growth experiments (A/B tests) to drive user acquisition and activation, using data to inform next steps.
- Work across React (web) and React Native (mobile), shaping the trajectory of an increasingly critical mobile app.
- Bridge front‑end and back‑end: extend APIs, improve data layers, and shape Node.js/TypeScript systems behind the UI.
What You Bring
- 3‑6 years of professional full‑stack engineering experience, shipping consumer‑facing products at scale.
- Strong proficiency in React (web) and React Native (mobile), with comfort extending into Node.js/TypeScript back‑ends.
- Data fluency: you can write SQL, set up and interpret experiments, and use metrics to drive product decisions.
- A product engineering mindset from a consumer tech or marketplace background, with experience building AI capabilities.
This role is based in London, requiring 3‑4 days in‑office per week.
