Founding Full-Stack Software Engineer
Company Overview
At Open Ring (www.o-ring.tech), we’re behind the world’s first open-source smart ring platform, built for researchers, startups, and developers. We’re building a community-driven ecosystem for wearable tech innovation. As we scale, we’re eager to welcome exceptional talent ready to contribute to a global movement.
Role Overview
We’re building an open smart-ring platform that brings together wearable hardware, embedded firmware, mobile applications, web products, APIs, and developer tools. We’re looking for a strong Full-Stack Software Engineer to own and ship software across the product stack, from our WordPress/CMS website and web applications to backend services, mobile integrations, internal tools, and developer-facing platform features.
In this role, you’ll build and maintain customer-facing web experiences, dashboards, admin tools, backend APIs, data workflows, and mobile-connected product features. You’ll work with sensor data from wearable hardware, support BLE/mobile integration, and help create the software layer that enables data synchronization, visualization, exports, SDK access, and integrations for developers and researchers. It’s a broad, high-ownership engineering role for someone who can move confidently across frontend, backend, mobile, CMS, APIs, and platform development, and who is comfortable shipping practical, reliable software in a fast-moving startup environment.
Key Responsibilities
- Own full-stack feature development across web applications, backend services, mobile-connected product features, internal tools, and developer-facing platform products.
- Maintain and extend our WordPress/CMS website, including custom templates, plugin integrations, landing pages, analytics, performance, technical SEO, security, and backend integrations.
- Build customer-facing dashboards, admin tools, developer portals, onboarding flows, and data-management interfaces.
- Extend iOS and Android app functionality for wearable-device workflows, including BLE discovery, pairing, GATT interactions, background sync, offline data capture, and reconnection handling.
- Design and maintain backend services, REST APIs, authentication, database schemas, data models, background jobs, and third-party integrations.
- Build sensor-data workflows for ingestion, synchronization, storage, visualization, logging, exports, analytics, and data-quality checks.
- Collaborate with the embedded systems engineer on BLE protocol design, GATT services/characteristics, payload formats, device-state handling, and firmware/mobile integration testing.
- Build developer-facing tools, including SDKs, API documentation, sample applications, integration guides, and data-export utilities.
- Improve reliability, performance, security, observability, testing, deployment, and maintainability across the software stack.
- Work closely with the founding team, users, researchers, and partners to prototype quickly, test with real hardware, and ship production-ready features.
Qualifications
- 5+ years of software engineering experience, with strong full-stack web development experience.
- Strong JavaScript/TypeScript skills and experience with React, Next.js, Vue, or similar frontend frameworks.
- Backend/API experience using Node.js, Python, PHP, Ruby, Go, or similar, including REST APIs and database-backed applications.
- Experience with databases such as PostgreSQL, MySQL, Firebase, Supabase, MongoDB, or similar.
- Comfortable with WordPress/CMS development, including theme/plugin customization, PHP, performance, SEO, security, and maintenance.
- Mobile development experience is a strong plus, especially React Native, Swift/iOS, Kotlin/Android, or native integrations.
- Bonus: experience with IoT, BLE/GATT, wearable devices, device connectivity, or sensor-data workflows.
- Able to own features end-to-end, communicate clearly, and ship quickly in a lean startup environment.
Why Join Us
- Work directly with a small founding team and own meaningful parts of the product across web, mobile, hardware integrations, and platform.
- Build a next-generation wearable platform that opens sensor data to developers, researchers, and partners through APIs, SDKs, dashboards, and data tools.
- Move quickly from prototype to pilot to production with real hardware and early users.
- Shape the architecture across web applications, backend services, mobile apps, data workflows, and device integrations.
- Equity-based compensation with long-term upside.
