Summary
About the role
We’re a new team operating with startup urgency to create new customer growth. Expect end‑to‑end ownership—rapid experimentation, fast shipping, and leaning in wherever the work takes you, beyond your job title. If you’re ambitious, hard‑working, and excited to build 0→1 against tall ambitions, you’ll thrive here.
You will be responsible for
- Own end-to-end experience design (UX, UI, service): define experience principles, map future-state journeys/service blueprints that unlock new Tesco customer growth.
- Translate vision into shippable UI: deliver accessible, high-quality interfaces and micro-interactions for MVPs and live trials, aligned to Tesco’s design system.
- Build rapid experiment collateral: clickable prototypes, flows, content/variant packs, and stimuli to enable weekly user tests, A/Bs, and in‑market experiments.
- Drive customer validation: plan/run research and usability, synthesize insights, and convert learnings into prioritized design decisions at speed.
- Collaborate for outcomes: partner with PM, Engineering, and Data/ML to leverage new AI capabilities, define hypotheses/metrics, iterate fast—and operate confidentially under NDA.
As a small and focused team, we need all of our recruits to be excited by a team with a startup mindset -
- Bias to action: you move from idea to test to live quickly, and learn in the wild.
- Scrappy and resourceful: you ship with the tools to hand; progress over perfection.
- Customer‑obsessed: you validate with customers and let insight drive decisions.
- Ownership: you take responsibility for outcomes, not just tasks.
- Transparent communicator: you keep the team and stakeholders in the loop, early and often.
- AI‑forward: you use AI to accelerate research, synthesis, and delivery.

Operational Experience
- Run hypothesis-driven design sprints: plan weekly cycles, define testable bets, facilitate workshops and keep momentum high.

- Backlog and delivery: partner with PM on requirement gathering, discovery and prioritisation
- AI ops: use AI to generate variants, UX copy, and flows; document prompts and guardrails; sanity-check for bias/hallucinations.
- Compliance and privacy: operate under NDA; handle PII in research; align with GDPR and Tesco governance; raise DPIA needs when relevant.
- You excel in the core foundations of UX, UI & research from strategy to delivery, including but not limited to - UX design information architecture, wireframing and prototyping, usability evaluation, user-centred design, product methodologies, UX qual and quant
