Product Design Engineer

Design Engineer (AI Products) – National News Platform

Day rate: £650 (Inside IR35)

Duration: 6 months

Location: Central London (Hybrid – 3 office days)

We’re looking for a Design Engineer with strong UX/UI craft, interaction design expertise, and front‐end product-building experience to redefine the future of AI‐driven digital experiences for a major national news platform used by millions.

This is not a backend engineering role.

This is a role for someone who lives at the intersection of product design and front‐end engineering. Someone who cares deeply about user experience, visual quality, interaction detail, and how design translates into a real shipped product.

You’ll prototype new concepts in Figma, validate interactions rapidly, and bring them to life with polished, production-ready UI. You’ll collaborate with product designers, UX researchers, and engineering leads to shape AI‐powered interfaces that feel intuitive, elegant, and deeply user‐centred.

You’ll Thrive Here If You...

  • Are a designer‐builder who loves crafting beautiful interfaces and then bringing them to life in code
  • Obsess over interaction design, micro‐interactions, and user flow improvements
  • Have strong opinions on layout, hierarchy, typography, visual polish, and motion
  • Can translate complex AI capabilities into clear, human‐centred UX
  • Think like a Product Designer but build like a UI Engineer
  • Believe great design is measured by how it ships, not just how it looks in a file

What You’ll Do

  • Design and build AI‐powered user experiences, focusing on clarity, usability, and interaction quality
  • Prototype rapidly in Figma, exploring content discovery, search, summarisation, and intelligent UI behaviour
  • Translate prototypes into high‐quality React interfaces
  • Work hands‐on with design systems to create accessible, scalable, reusable UI components
  • Collaborate with designers to test, refine, and elevate user journeys
  • Bring AI capabilities (LLMs, RAG, embeddings) to life in a way that feels natural and user‐first
  • Influence product direction by demonstrating what’s possible through UX‐led prototypes

Essential Requirements:

  • Strong UX/UI and interaction design background — with a portfolio showing shipped, consumer-facing digital products
  • Experience building rich, interactive UIs in React
  • A designer’s eye for detail: spacing, motion, feedback, clarity, and hierarchy
  • Ability to take an ambiguous user problem and shape it into an elegant, thoughtful experience
  • Experience integrating AI/LLM features into user interfaces
  • Comfortable owning a feature end‐to‐end, from concept sketches to polished UI

Your ideas could shape how millions experience the news. If you’re ready to build what’s next, please apply with an up-to-date CV to get a conversation rolling.
