#### About the role
Orbit Connection PBC is building a consent-based proximity platform. We're pre-launch, seed-funded, and hiring our first engineer to build the MVP alongside the founder.

The core mechanic:  Two independent users, both moving, both anonymous to each other until mutual consent, navigating toward a convergence point that recalculates continuously. Plus, an instant-disconnect that has to be genuinely instant.

If you've only built location features that pin a user to a fixed destination, this will be new territory.  That's fine, but we need someone who's worked with continuous location streams, not just one-shot geolocation calls.

#### Scope
Roughly 14 weeks across four sprints:
Sprint 1: Auth, biometric verification integration (Persona), profile creation, AI-assisted profile flow
Sprint 2: Proximity radar, mutual consent gate, instant-disconnect
Sprint 3: Convergence navigation, density mapping, venue-facing data endpoints
Sprint 4: Integration testing, third-party security audit remediation, App Store submission

#### Required
- 5+ years mobile, 3+ years React Native in production
- Shipped at least one consumer app to the App Store and Play Store
- Real-time location experience: background location, continuous position streaming, battery-conscious geofencing, handling GPS degradation indoors and in dense urban environments
- Backend competence - Supabase, Firebase, or equivalent.  You'll own the data layer, not just consume an API
- WebSocket or equivalent real-time transport at scale
- Comfortable owning architecture decisions and explaining tradeoffs to a non-engineer founder

#### Strongly preferred
- Two-way or multi-user coordination (rideshare, delivery, live tracking, multiplayer)
- Identity verification integrations
- WCAG accessibility experience
- Have opinions about location privacy and can defend them

#### How we work
- Two-week paid trial scope first: auth flow and profile creation, working and demoable.  If it's a fit on both sides, we extend to the full build.
- Weekly sync with the founder.  Async otherwise.  You'll have direct product access, no layers, no committee.
- Constraints you should know up front
- User data never enters third-party AI training. Inference only.  This is architectural, not aspirational.
- Independent security audit before any user touches the product.  All findings should be resolved.
- Accessibility is a requirement, not a phase-two item.
