AI Software Engineer II

At Relativity Space were building rockets to serve todays needs and tomorrows breakthroughs. OurTerran R vehicle will deliver customer payloads to orbit meeting the growing demand for launchcapacity. But thats just the start. Achieving commercial success with Terran R will unlock newopportunities to advance science exploration and innovation pioneering progress that reaches beyondthe known.

Joining Relativity means becoming part of something where autonomy ownership and impact exist at every level. Here youre not just executing tasks; youre solving problems that havent been solved before helping develop a rocket a factory and a business from the ground up. Whether youre in propulsion manufacturing software avionics or a corporate function youll collaborate across teams shape decisions and see your work come to life in record time. Relativity is a place where creativity and technical rigor go hand in hand and your voice will help define the stories were writing together. Nowis a unique moment in time where its early enough to leave your mark on the product the process andthe culture but far enough along that Terran R is tangible and picking up momentum. The mostmeaningful work of your career is waiting. Join us.

About the Team:

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 Relativitys 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.

About the Role:

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.

About You:

• Bachelors degree or higher in Computer Science or a related engineering field (Computer Software Electrical Aerospace)
• 3 to 5 years of experience building shipping and iterating on applications and services
• Practical experience building AI features with large language models such as agents retrieval-augmented generation tool use or evaluation and shipping them to real users
• Hands-on experience building with large language models whether through coursework projects or self-directed work
• Experience designing in collaboration with non-software stakeholders
• Proficient in the languages and tools you love most and willing to learn new ones

Nice to haves but not required:

• Experience designing and scaling AI or service architectures that support high-performance user-facing applications
• Experience building evaluation and observability systems that keep AI reliable in production
• Background in data engineering applied machine learning or building and maintaining knowledge bases and ontologies
• Experience turning research into working prototypes and reading current AI literature to inform design choices
• Experience developing debugging and shipping software products on large code bases that span platforms and tools
• Exposure to manufacturing hardware robotics or other physical-world domains

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race religion color national origin gender sexual orientation age marital status veteran status or disability status.
