Details: Competitive hourly rate (Senior, Fractional). Long-term engagement if mutually successful

Job ID: 26FRA301

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.

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.

• 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

• 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

• 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

• Define how PrimeNG components are used (tables, forms, filters, modals)

• Establish behavioral standards:

• States

• Errors

• Permissions

• Progressive disclosure

• Prevent almost-the-same component variants

• 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

• Review v0 prototypes and early implementations

• Provide fast, opinionated feedback

• Help PMs reason through UX tradeoffs

• Establish clear guardrails PMs can confidently operate within

• 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.

• 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

• 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.
