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, * 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 ## Description 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, * 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. ## Related Videos - [Intro to Flutter Development](https://www.wearedevelopers.com/videos/170-intro-to-flutter-development) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Minimal infrastructure for Real‑Time Phone Agents: transcripts in, responses out](https://www.wearedevelopers.com/videos/1736-minimal-infrastructure-for-real-time-phone-agents-transcripts-in-responses-out) - [There's an app for that - on the role of cross platform development in the app development ecosystem](https://www.wearedevelopers.com/videos/278-there-s-an-app-for-that-on-the-role-of-cross-platform-development-in-the-app-development-ecosystem) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Leveraging Server-Sent Events (SSE) for Efficient Data Streaming in UI Development](https://www.wearedevelopers.com/videos/905-leveraging-server-sent-events-sse-for-efficient-data-streaming-in-ui-development) ## Related Articles - [React Developer Salary [2023]](https://www.wearedevelopers.com/magazine/198-react-developer-salary-2023) - [16 Best Free React UI Libraries in 2025](https://www.wearedevelopers.com/magazine/148-16-best-free-react-ui-libraries-in-2025) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Cross Platform Mobile Development Frameworks to Use in 2025](https://www.wearedevelopers.com/magazine/404-cross-platform-mobile-development-frameworks-to-use-in-2025)
