Bare Developer – Cross-Platform Runtime Engineer

About the role

We are looking for a Bare Developer to join a partner company’s engineering team. The role focuses on building and evolving a lightweight cross‑platform runtime and its ecosystem of native modules, bridging C and JavaScript to expose OS‑level capabilities.

Key responsibilities

• Design, develop and maintain native modules in C and JavaScript, owning the full lifecycle from implementation to production deployment.
• Build cross‑platform system integrations (Bluetooth, networking, filesystem, cryptography) accessible through JavaScript APIs.
• Maintain and improve cross‑compilation toolchains and CI pipelines for macOS, Linux, Android and iOS.
• Contribute to the runtime core, enhancing module systems and native addon architecture.
• Debug complex, multi‑OS issues to ensure stability, performance and reliability of native modules.

Required profile

• Strong professional experience in C programming with ability to write and debug native, cross‑platform system‑level code.
• Advanced JavaScript expertise and solid understanding of runtime internals and module systems (e.g., Node.js).
• Experience developing native addons using N‑API, node‑gyp or equivalent frameworks.
• Familiarity with asynchronous I/O systems such as libuv and event‑driven architectures.
• Proficiency in cross‑platform development across macOS, Linux, Android (NDK) and iOS (Xcode), including cross‑compilation workflows.
• Strong written communication skills and a self‑directed, autonomous working style.

Required skills

• C programming
• JavaScript
• Node.js runtime
• N‑API
