About this role

## Software Engineer, Research Tooling **SpaceXSI** is building Super Intelligence to help humanity understand the universe. The Research Tools team builds the infrastructure and applications that enable researchers to iterate quickly, run complex experiments, and extract insights. ### About the Role This is a **full-stack product-engineering** role. You’ll work directly with researchers and engineers to understand workflows, identify bottlenecks, and rapidly ship solutions that multiply productivity. Your work may include platforms for experiment orchestration, visualization tools for model evaluation, and abstractions for understanding model behavior at scale. **No prior ML or research experience is required.** ### What You’ll Do - Build and maintain full-stack applications and infrastructure researchers rely on daily (experiment setup, feedback collection, results analysis). - Own complete product areas end-to-end: user needs → design → implementation → iteration, setting standards for research app development. - Create reusable platforms and tools to speed up new research applications; prototype, ship, and iterate based on real usage. - Partner with research teams to turn workflows and pain points into intuitive interfaces and abstractions. ### You May Be a Fit If - You’ve built tools, platforms, or infrastructure for technical users (engineers, researchers, data scientists, analysts, etc.). - You’ve shipped full-stack products and owned systems from UI to storage/services, using technologies such as **TypeScript + React** with **Node, Python, or Go**. - You’ve built dense, data-facing tools (e.g., transcript viewers, diffing systems, review queues, observability products, operational dashboards) and care deeply about how structured data is rendered. - You have strong product instincts, can identify the right problems, and can move from concept to working prototype quickly. - You move fast under ambiguity, collaborate closely with researchers/domain experts, and take open-ended problems to reliable products. ### Applying If there’s a fit, you’ll be contacted to schedule **2–3 short technical interviews**, followed by an **onsite** where you’ll work on a small project, discuss ideas, and meet the team.
