Full Job Description
đź“‹ Description
- • UX/UI Designer (Mobile) at Aphex Technologies Inc. in London, responsible for owning mobile experience design across the Diary product, which is the company's biggest revenue lever for 2026 and used by construction teams in field environments.
- • Day-to-day responsibilities include end-to-end design of mobile features from briefing to shipped UI, defining interaction patterns for real-world constraints like gloved hands and patchy connectivity, collaborating daily with PMs and Flutter engineers, reviewing builds for quality, and evolving the design system with a focus on mobile components.
- • Aphex Technologies Inc. is a market-leading construction planning platform replacing outdated spreadsheets with multiplayer tools used by major contractors like Acciona and CPB Contractors to deliver projects from £50 million to multi-billion pound infrastructure, with a founding thesis that owning the planning layer enables solving high-friction adjacent processes in project orchestration.
- • The role offers the opportunity to shape what gets built, visit construction sites, push back on designs that don’t meet the bar, and grow into a Senior Designer or Mobile Design Lead as the team and product surface expand, working directly with the Head of UX and CEO.
🎯 Requirements
- • 4+ years product design experience with a strong mobile portfolio (iOS, Android, or cross-platform)
- • Proven ability to design for complex workflows, not just simple consumer apps
- • Solid interaction design skills: flows, states, and edge cases—not just screens
- • Comfortable working within platform constraints—a design that can't be built isn't a good design
- • Can work across the full design process: exploration, detailed design, QA
- • Remote-first mindset: write clearly, give and receive feedback asynchronously
🏖️ Benefits
- • Remote-first role working across UK, Europe, and Australia time zones with flexible working hours and async collaboration
- • First dedicated mobile designer—define what good looks like with a path to Senior Designer or Mobile Design Lead
- • Work directly with Head of UX and CEO (acting Head of Product) with genuine influence on product direction
- • Annual offsite: In 2025 the team met in Da Nang, Vietnam—you'll need to join us to see where we have planned in 2026
- • Join a team that takes ownership, focuses on quality, and genuinely enjoys solving hard problems together
