Overview

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


Responsibilities

* 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.


Values

* 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.


Requirements

* UX, UI, and service design across app, web, and in‑store journeys.
* Retail/e‑commerce experience.
* Experience working in a start‑up / scale‑up.
* Rapid prototyping and creating test collateral for weekly experiments.
* Designing AI‑powered and personalized experiences in partnership with Data/ML.
* Design systems: building/extending components and tokens; aligning to enterprise systems (e.g., Tesco).
* Accessibility and inclusive design baked into delivery.
* Mixed‑methods research and experiment design.
* Operating under NDA with strong documentation and stakeholder storytelling.
* Interaction design and prototyping.
* Creation and implementation of design systems.
* Accessibility principles.


Operational Experience

* Run hypothesis‑driven design sprints: plan weekly cycles, define testable bets, facilitate workshops and keep momentum high.
* Experiment ops: create test plans, recruit GDPR‑compliant participants, manage incentives/scheduling, capture insights and playback to the wider team.
* 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 qualitative and quantitative research.
