Product Design Engineer

Accountabilities:

• • Explore product opportunities through user research, experimentation, prototyping, and iterative design to identify the strongest solutions.
  • Carry product concepts through to production-ready front-end experiences, combining design decisions and implementation within the same workflow.
  • Help define what is worth building by engaging with users, challenging assumptions, validating problems, and shaping scope with the product squad.
  • Design and build intuitive supervisory interfaces for AI-native workflows, including triage queues, confidence and citation patterns, briefings, and other decision-support experiences.
  • Use AI tools throughout the product development lifecycle, including research, design, prototyping, development, and testing.
  • Evaluate AI-generated outputs critically, applying strong product and design judgment rather than relying on automated results without review.
  • Collaborate closely with software engineers responsible for the underlying systems and ensure the final experience works effectively with the technical architecture.
  • Take ownership of front-end quality, including performance, accessibility, responsive behaviour, cross-device compatibility, and perceived speed.
  • Continuously iterate on products based on user feedback, technical constraints, and real-world usage.
  • Deliver polished, production-ready experiences that balance usability, functionality, technical feasibility, and visual quality.

  Requirements:

  • Proven experience designing and building front-end products through to production, with ownership of both the experience and implementation.
  • Strong design judgment and visual/product taste, with the ability to distinguish genuinely excellent experiences from interfaces that are merely functional.
  • Strong product instinct and the ability to challenge assumptions, reduce unnecessary scope, and validate ideas with real users.
  • Fluency in modern web development and front-end engineering practices.
  • Demonstrated experience using AI tooling across multiple stages of product development, including research, design, prototyping, coding, and testing.
  • Strong understanding of AI limitations and failure modes, with the ability to identify when AI-generated output appears correct but is not.
  • Experience creating data-rich, complex, or high-stakes interfaces for demanding professional users.
  • Ability to communicate credibly with domain experts and translate complex workflows into clear, effective product experiences.
  • Strong understanding of responsive design, accessibility, performance, and cross-device behaviour.
  • Ability to work effectively in a multidisciplinary product squad alongside software engineers and other stakeholders.
  • Candidates may come from design, engineering, or multidisciplinary backgrounds; the key requirement is the ability to design, build, and ship high-quality products.

  Benefits:

  • Fully remote working opportunity within the UK or Europe.
  • Opportunity to combine product design and front-end engineering without traditional handoffs between design and development.
  • Significant influence over product direction, scope, and user experience.
  • Opportunity to work on AI-native product experiences where human oversight, judgement, and authorisation are central.
  • Hands-on ownership from early exploration and prototyping through to production.
  • Collaborative product environment alongside experienced software engineers and product specialists.
  • Opportunity to use modern AI tools throughout the full product development lifecycle.
  • High level of autonomy and responsibility for the quality and impact of shipped experiences.
  • Opportunity to work on complex, data-rich products designed for demanding professional users.
