## About the Role

 + Familiarity with component-based design systems
 + Experience working with engineers directly

## Description

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.**, + 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
