Software-defined networking platform for zero-trust connectivity across devices and networks
ZeroTier operates a lean, engineering-focused team (11–50 employees, 6 engineers hiring) building distributed networking infrastructure in Go, Rust, and C/C++. The tech stack—PostgreSQL, Redis, Google Cloud Pub/Sub, and OpenFGA—reflects a platform designed for scale and access control rather than classical network appliances. Active projects span central API development, management portal, and client software, while pain points cluster around platform scaling and customer success friction, suggesting the company is transitioning from product-led to sales-led motion.
ZeroTier delivers software-defined networking that abstracts away geographic and network boundaries, enabling secure connectivity across local and wide-area deployments. Founded in 2015 and based in San Francisco, the company operates with a small, senior-heavy engineering team (4 senior engineers, 2 directors, 1 staff) and minimal sales headcount, indicating developer-centric go-to-market. The product serves use cases spanning remote access, IoT/IIoT, SDWAN, and cybersecurity. Hiring activity remains steady, with roles in the United States and Netherlands, and active investment in API infrastructure, management portals, and customer success processes.
Go, Rust, C, and C++ form the core. Supporting languages include JavaScript, TypeScript, and Vue for frontend, alongside networking fundamentals like TCP, UDP, and STUN.
Central API development, management portal design, client software, public service interfaces, Vue.js frontend features, CI/CD pipeline improvements, and technical sales enablement assets.
