At Relativity Space, we’re building rockets to serve today’s needs and tomorrow’s breakthroughs. Our Terran R vehicle will deliver customer payloads to orbit, meeting the growing demand for launch capacity. But that’s just the start. Achieving commercial success with Terran R will unlock new opportunities to advance science, exploration, and innovation, pioneering progress that reaches beyond the known.
Joining Relativity means becoming part of something where autonomy, ownership, and impact exist at every level. Here, you're not just executing tasks; you're solving problems that haven’t been solved before, helping develop a rocket, a factory, and a business from the ground up. Whether you’re in propulsion, manufacturing, software, avionics, or a corporate function, you’ll 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 we’re writing together. Now is a unique moment in time where it’s early enough to leave your mark on the product, the process, and the culture, but far enough along that Terran R is tangible and picking up momentum. The most meaningful 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.
About the Role:
As a Lead Software Engineer on the Factory Platform team, you'll combine hands-on technical leadership with direct people management. You'll own the full software development lifecycle for your squad — from concept and trade study through implementation, deployment, and iteration — while also being accountable for the growth, performance, and hiring of the engineers on your team.
Manage a team of software engineers: conduct 1:1s, write and deliver performance reviews, support career development, and drive hiring
Set and uphold engineering standards for your team: code quality, testing, deployment practices, incident response, and on-call culture
Lead architectural design and trade studies for new features and systems across planning, scheduling, purchasing, manufacturing operations, and test data tooling
Maintain meaningful individual contribution - you are expected to stay technically sharp and ship code, not just review it
Partner with cross-functional stakeholders (manufacturing, operations, propulsion, test launch) to translate domain requirements into software
Mentor and grow engineers at all levels; identify gaps in the team and close them through coaching or hiring
Technologies we use:
Python, React, Typescript, Go
Iceberg, BigQuery, Duckdb, DBT, Postgres
AWS, GCP, Kubernetes (both cloud and on-prem), Terraform, Helm
About You:
Bachelor's or higher in CS or a related engineering field
5+ years of software engineering experience across multiple production systems
Proven track record hiring, retaining, and developing engineers
Expert in React and modern frontend tooling
Fluent in at least one backend language (Go, Python) and willing to range across the stack
Comfortable driving architectural decisions and building buy-in across engineering and non-engineering stakeholders
Strong written and verbal communication - you can write a crisp design doc and also give useful, timely feedback to a struggling engineer
Nice to haves but not required:
2+ years in an engineering management or tech lead-manager role, with direct reports
Experience designing and scaling service architectures for high-performance frontend operations
Background in systems-level programming (synchronization, memory management)
Experience with low-latency or safety-critical software
History of shipping software across large, multi-platform codebases
