Part-time : 20-30 hours per month Details: Competitive hourly rate (Senior, Fractional). Long-term engagement if mutually successful Job ID: 26FRA301 Fractional Product Systems Designer (Web + iOS) - Remote (U.S.- based) Overview Serious Development builds internal business applications at speed using: v0 for prototyping, Angular + PrimeNG for implementation, Native iOS apps that feel like iOS, not web-on-a-phone. We are seeking a Fractional Product Systems Designer (Web + iOS) to design how our products behave over time. Why This Role Exists We build internal business applications at speed using: v0 for prototyping Angular + PrimeNG for implementation Native iOS apps that must feel like iOS, not web-on-a-phone As our velocity increased, traditional screen-based design became unnecessary. What did become necessary is system-level UX ownership . This role exists to ensure our products remain: Predictable Consistent Native to their platforms Easy to learn and hard to misuse You will not be designing every screen. You will be designing how the product behaves over time. Who You Are Required Senior-level product or systems designer Experience with internal or enterprise applications Strong systems thinking; comfortable defining rules and constraints Deep familiarity with iOS as a platform (not just mobile UI) Comfortable challenging PMs and saying “don’t ship that” Pragmatic, opinionated, and not precious about visuals Strong Plus Experience cleaning up inconsistent products Familiarity with component-based design systems Experience working with engineers directly Prior fractional or advisory roles Red Flags (for us) Portfolio-first, system-light background Strong preference for redesigns over convergence Focus on “delight” over clarity and predictability Reliance on Figma as the primary output What You’ll Be Responsible For Product-wide UX coherence Own interaction patterns across the product Ensure similar problems are solved the same way Reduce inconsistency as new modules are added Prevent UX drift as multiple PMs and teams ship in parallel Working within existing products Audit current applications and patterns Identify what already works and should be preserved Drive convergence — not redesign-for-the-sake-of-redesign Respect user muscle memory Web UX (Angular + PrimeNG) Define how PrimeNG components are used (tables, forms, filters, modals) Establish behavioral standards: States Errors Permissions Progressive disclosure Prevent “almost-the-same” component variants iOS UX (Native-first) Ensure strict alignment with Apple Human Interface Guidelines Catch web/Android patterns leaking into iOS Enforce native navigation, gestures, and control usage Prioritize platform correctness over internal consistency when they conflict Partnering with PMs Review v0 prototypes and early implementations Provide fast, opinionated feedback Help PMs reason through UX tradeoffs Establish clear guardrails PMs can confidently operate within What You Will Not Be Doing Pixel-perfect mock production Designing every feature or screen Maintaining Figma parity with code Visual branding or marketing design Creating handoff artifacts for engineers If your default output is screens, this is not the right role. What Success Looks Like UX feels consistent across modules and platforms PMs move fast without inventing new patterns Fewer usability questions from users Faster onboarding with less training No “why does this work differently over here?” moments No large-scale UX rewrites six months later How You’ll Work Review-heavy, not production-heavy Embedded early in feature thinking, not late-stage polish Prefer rules, patterns, and written guidance over visuals Use Figma only when a concept cannot be expressed clearly in text or prototypes Code and prototypes are the source of truth.
