Product Designer responsible for mobile experience in Aphex's Diary app, bridging quality between mobile and web designs. Join a senior design team shaping product direction.
Responsibilities
Own Mobile Design
End-to-end design of mobile features from briefing through to shipped UI
Define and evolve interaction patterns that feel native and considered
Design for real constraints: gloved hands, outdoor visibility, shared devices, patchy connectivity
Work closely with Flutter engineers to ensure designs translate faithfully
Bridge the quality gap between web and mobile
Ship with the Team
Daily collaboration with PMs on feature scoping—they bring user context, you bring design thinking
Partner with Flutter engineers on feasibility and implementation fidelity
Review builds, catch issues before they ship
Be the person who says 'this isn't right yet' when it matters
Build the System
Evolve Aphex's design system, particularly mobile components
Work with the Head of UX on standards and quality benchmarks
Ensure consistency across web and mobile where it counts
Requirements
4+ years product design experience, with 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
Flutter experience and understanding of cross-platform mobile constraints (highly valued)
Experience designing for field workers, industrial users, or non-desk environments (highly valued)
Vertical SaaS or B2B experience (highly valued)
Design systems experience (highly valued)
Construction or infrastructure industry knowledge (highly valued)
Benefits
Remote-first role working across UK, Europe, and Australia time zones
Flexible working hours with async collaboration
Join a team that takes ownership, focuses on quality, and genuinely enjoys solving hard problems together
