(Senior) Full-stack Developer (Next.js / Node.js)
Your mission
Your mission is to develop and maintain intuitive, high-performance web applications and APIs that provide seamless access to OKAPI:Orbits’ end‑to‑end solutions across Mission Design, Space Situational Awareness (SSA), Space Traffic Management (STM), Flight Dynamics (FD), and Space Traffic Coordination (STC) — supporting the entire lifecycle of satellite operators.
You design and implement elegant user interfaces and robust service integrations that connect complex space-data pipelines with an accessible, reliable user experience.
You work on the systems that enable satellite operators and space agencies to visualize, plan, and manage their missions efficiently in an increasingly dynamic orbital environment.
Research shows that women are less likely than men to apply for a position unless they meet 100% of the listed requirements. Please know that if it’s your case — but you are passionate about space technology, building reliable software, and contributing to a more sustainable space environment — we strongly encourage you to apply.
OKAPI:Orbits already brings together a highly diverse team, and we actively continue to strengthen this diversity, as research consistently shows that heterogeneous teams achieve higher performance and drive innovation.
