Software Engineer - Internal Tools
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. This role values product ownership, taste and narrow specialization.
Our team is contributing to Toolbox — our unified Research Platform for model training orchestration, evaluations, benchmarking, and experiment management. We are open to all levels from new grads to senior engineers.

Outstanding communication skills — you can clearly articulate trade-offs, technical decisions, and product thinking to both technical and non-technical stakeholders
Strong product intuition and ownership mindset
Strong taste & sensitivity — you have a sharp sense for quality. You can naturally feel and detect what feels good versus what feels off or uncomfortable across everything you build (frontend interfaces, backend APIs, data flows, system architecture, etc.).
Proven technical excellence in at least one area (UX/frontend, backend, data, agentic systems, etc.)
PREFERRED SKILLS AND EXPERIENCE:
Previously founded a startup or joined a fast-growing early-stage startup
Familiarity with AI/ML workflows, annotation tools, or research platforms
