A highly respected, product-led software company is hiring a UX-focused Product Designer to take ownership of user experience across complex, data-heavy product areas. This is not a brand, marketing, or visual-polish role. You’ll be designing for power users, elite SW Engineers and technical teams who work daily inside dense, mission-critical interfaces. These products sit at the heart of real production systems, where clarity, efficiency, and correctness matter more than surface-level aesthetics.
If you enjoy hard problems, systems thinking, and working shoulder-to-shoulder with SW Engineers, this role will suit you.
Who this role is for
- Product Designer (Complex Systems / B2B)
- UX Designer for developer tools or technical platforms
- Interaction Designer working on dense, state-heavy interfaces
- Design Technologist or UX Engineer (design-leaning)
- Systems-minded Designer who enjoys complexity rather than hiding it
If your background is primarily brand, marketing websites, or purely visual design, this is unlikely to be a good fit.
What you’ll be doing
- Owning UX design for complex, data-intensive product areas
- Understanding real user workflows, mental models, and constraints in production environments
- Designing interaction models, workflows, and behaviours — not just screens
- Producing practical design artefacts: wireframes, interaction specs, prototypes, and documentation
- Working closely with engineers to ensure designs are feasible, performant, and implemented correctly
- Iterating designs based on user research, usability testing, and real usage data
- Helping define and evolve UX standards and design language across the product
- Occasionally contributing small frontend changes (React-based) to close the loop between design and delivery
- Supporting user research to uncover genuine customer pain points and opportunities
What you’ll need
- Solid experience as a Product Designer, UX Designer, or Interaction Designer on complex software products
- Proven ability to design for power users and data-heavy workflows
- Strong grounding in interaction design, usability principles, and information architecture
- Experience planning and running user research and usability testing
- Technical fluency, including:
- Ability to inspect DOM, layout, and interaction behaviour
- Comfortable collaborating with engineers and reading frontend code
- Working comfortably with Git
What’s in it for you
- Shape interaction models used inside thousands of real production systems
- High autonomy and ownership over meaningful product areas
- Close collaboration with experienced engineers who care about quality
- Minimal process, low ceremony, and no design theatre
- A product where UX decisions have long-term impact at serious scale
- Competitive salary, strong benefits, and a flexible hybrid working model
