Serious Development

## **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.

**Work Arrangement:** Remote (U.S. Based)

**Hours:** Part-time, 20-30 hours per month

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

**Job ID:** 26FRA301
