AI Software Engineer

• The Terrestrial Software team is building the foundation for an automated rocket factory and integrated launch platform
• Their mission is to automate and streamline workflows across the entire lifecycle of Terran R, from raw material intake to launch operations and eventually manufacturing on Mars
• Today, that means partnering directly with teams across design, materials, manufacturing, and test and launch to design, implement, and deploy end-user enterprise-wide applications, industrial automation, data analytics infrastructure, and next-generation AI to solve real problems and accelerate progress
• Long term, the team is laying the groundwork for a modular, scalable software platform that can power highly autonomous operations on Earth and beyond
• This is a team for builders and thinkers who thrive on cross-functional impact and want to shape the digital backbone of our future in space
• The AI, Data and Platform Engineering team leads Relativity’s initiative to make AI a core part of how we design, build, and test rocket hardware
• We build the applications, agents, data foundations, and platform that put AI in the hands of engineers and operators across the company
• We are a small, high-ownership team that ships quickly, works directly with users, and treats reliability and evaluation as first-class parts of every AI product
• You will help build AI systems used by engineers and operators across the company, working across the full software development life cycle: concept, design, implementation, and ongoing iteration
• Build AI-powered applications and agents on top of foundation models, and make them reliable in production
• Follow agile development practices and ship quality software that is continuously integrated and deployed
• Solve complex problems with simple solutions
• Work directly with users and stakeholder teams to define requirements, implement solutions, and iterate
• Technologies we use: Python, React, TypeScript, Go
• Foundation models (Claude and others), agent and orchestration frameworks, retrieval and vector search, LLM evaluation tooling
• Spark, Iceberg, DuckDB, Redshift, DBT, Postgres, Mongo
• AWS, Kubernetes (cloud and on-prem), Terraform, Helm
