• Motivated and engaged team
• Open communication and active knowledge sharing
• Direct support from project leadership
• Clear specifications and well-defined requirements
• Opportunity to contribute to a high-impact, nationally relevant initiative

The Role 
Our app is packed with powerful features, but users complain it's confusing: they get lost, don't know the next step, and navigate too many places. We need a senior UX strategist (not a UI/visual designer) who excels at turning dense, overwhelming products into clear, guided, intuitive experiences.

This is a high-impact role focused on fixing core confusion through better information architecture, navigation, flows, and progressive disclosure. You’ll own the experience strategy end-to-end.

Key Responsibilities

• Analyze current journeys to pinpoint confusion, lost users, and excessive navigation.
• Redesign IA, navigation, user flows, and guidance so users always know what to do next.
• Create wireframes, interaction models, and prototypes focused on structure and behavior (not visuals).
• Raise overall UX maturity and mentor where needed.
   

Must-Haves

• 6+ years UX design experience, with 3+ years on complex, feature-heavy SaaS/web/mobile apps (enterprise tools, dashboards, creative suites—not simple websites).
• Strong portfolio with case studies showing simplification of confusing products: before/after flows, reduced steps, clearer guidance, and measurable improvements (task success, time-on-task, etc.). Include process and research—not just final screens.
• Expertise in: information architecture, user flow design, progressive disclosure, wayfinding, onboarding for dense products.
• Proven user research & testing skills to drive structural changes.

• Ability to explain/defend strategic UX decisions to stakeholders.

   

We don’t need 
Visual/UI polish—you won’t be primarily doing interfaces or aesthetics.
 

Nice-to-Haves

• B2B/enterprise experience with “tons of functionality.”

• Systems thinking or service design background.

   

Why This Role? 
Real ownership to solve our #1 user complaint. If you love making complex feel simple, this is your chance to make a massive difference.

Work Engagement
This is a contracted project-based position and has been listed as part-time.  All work is 100% remote.

Apply 
If selected for follow up we will ask for your previous UX designs.  If you cannot provide these we prefer you do not apply.

Job Description
We are looking for a Senior React / Supabase / TypeScript Developer who will take ownership of refactoring and hardening an existing SaaS platform. The core product logic, UI, and data layer are functional — this is not a rebuild. The goal is to elevate code quality, architecture, and operational reliability to production standards.

• Backend: Supabase (PostgreSQL, RLS, Deno Edge Functions, Auth, Realtime).
• Payments: Stripe (subscriptions, webhooks, metered billing).
• Auth: Google OAuth via Supabase Auth.
• Deployment: Currently Lovable Cloud (migration to Vercel or similar is in scope).
• AI Layer: External LLM API calls orchestrated through Edge Functions (you won’t need to write prompts, but you will need to understand and refactor the function architecture around them).

Scope of Work
The engagement is structured across three sequential phases.
Phase 1 — Audit & Architecture Proposal. Full codebase audit with a written proposal and prioritised recommendations. Sign-off from the client required before proceeding to Phase 2.
Phase 2 — Refactor & Harden. Systematic refactoring of the frontend architecture, Edge Functions, RLS policies, Stripe integration, and performance optimisation.
