At Tether, we’re building the next generation of decentralized, peer‑to‑peer communication and data‑sharing tools (including KEET and future products) on top of cutting‑edge P2P technology.
We are looking for an experienced full‑stack/mobile/desktop developer who loves shipping rock‑solid cross‑platform applications and has a strong interest (or existing experience) in peer‑to‑peer and distributed systems.
You’ll work in a small, high‑impact team alongside the core Holepunch engineers, helping bring fully decentralized apps to hundreds of millions of users worldwide.

- Ship new features rapidly, participate in code reviews, write tests, and optimize performance.
- Help external partners and the open‑source community build on the platform.
- Occasionally contribute improvements and bug fixes back to the underlying open‑source modules.
- 5+ years of professional software engineering experience
- Strong production experience with React Native and/or Electron (shipping apps that real users love)
- Very comfortable with Node.js and modern JavaScript/TypeScript ecosystems
- Proven experience designing and building local‑first applications where the local data model is the primary source of truth

- Familiarity with end‑to‑end encryption and secure local storage.
- Solid grasp of asynchronous programming, networking, and data synchronization concepts
