Job description

Serve First is a fast-moving, well-funded startup turning customer feedback into live dashboards and AI-driven alerts. 2025 roadmap: overhaul user journeys, add a design system, and launch new AI-powered workflows.

You’ll own the end-to-end product experience and iterate fast—low bureaucracy, maximum autonomy.

What You’ll Do

• Shape end-to-end UX. Map and optimize critical B2B workflows (survey creation, analytics, alerting). Product journey maps, wireframes, and interactive prototypes.
• Own the design system. Define UI patterns, components, and accessibility rules in Figma; partner with engineering for pixel‑perfect implementation.
• Drive user research. Plan and run interviews, usability tests, and feedback sessions with enterprise customers; translate insights into actionable design changes.
• Iterate relentlessly. Ship small, test, and improve. Use data (Heap, GA, in-app analytics) and qualitative feedback to refine flows.
• Collaborate cross‑functionally. Work side‑by‑side with Product, Backend, and Frontend teams; clarify requirements, hand off specs, review builds.
• Leverage AI wisely. Use AI design/copy tools to accelerate work, but validate everything—you own the outcome.
• Document everything. Keep flows, components, and rationale well documented for the distributed team.

Must Haves

• 5+ years designing complex B2B SaaS products (dashboards, workflows, admin interfaces).
• Portfolio that shows user‑centred process from research prototypes to shipped UI.
• Strong UX research chops: interviews, surveys, usability tests, heuristic reviews.
• Mastery of Figma (or Sketch/Adobe XD/etc.) and prototyping tools.
• Comfortable working with design systems and handing off to React engineers.
• Solid grasp of accessibility (WCAG) and responsive design principles.
• Excellent written & verbal communication—async first.

Nice to Haves

• Experience with customer‑feedback/survey or analytics platforms.
• Familiarity with React component libraries (Storybook, Chakra, MUI, etc.).
• Motion/interaction design skills (Lottie, Framer Motion).
• Basic HTML/CSS to tinker directly in code.

What We Offer

• Competitive salary
• Hybrid in Milton Keynes, at least 2 days a week
• Standard UK pension, 20 days holiday + public holidays.
• Generous kit & software budget.
• Small team = direct impact on the product experience.
