SpaceXAI’s mission is to create AI systems that can accurately understand the universe and aid humanity in its pursuit of knowledge. Our team is small, highly motivated, and focused on engineering excellence. This organization is for individuals who appreciate challenging themselves and thrive on curiosity. We operate with a flat organizational structure. All employees are expected to be hands‑on and to contribute directly to the company’s mission. Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates. We are looking for exceptional engineers and builders with great taste, strong product sense, excellent prioritization, and outstanding communication skills. You will own and elevate our mission‑critical research platform that directly accelerates SpaceXAI's frontier work. Our team is contributing to Toolbox — our unified Research Platform for model training orchestration, evaluations, benchmarking, and experiment management. You will design, build, and ship delightful, performant, and scalable systems that researchers and engineers love to use every day. This role values product ownership, taste and narrow specialization. We are open to all levels from new grads to senior engineers.
