Senior Software Engineer, Agentic Infrastructure

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:

Dark Matter Lab is a research group within Relativity Space focused on advanced aerospace systems agentic engineering and technologies outside the conventional build the infrastructure needed to turn new ideas into engineering capabilities people can actually depend on.

About the Role:

We run a stack of interconnected agentic systems SybilClaw yapCAD Mechatron Multigraph local LLM inference an inter-agent message bus parametric CAD pipelines a print farm and the infrastructure connecting it all. We need an engineer who can own and evolve these systems as they move from prototypes into production engineering infrastructure.

This role is for someone who has deployed an agentic harness (OpenClaw Hermes SybilClaw or something comparable) in a real work environment. You understand what it takes to make these systems reliable when engineers depend on them every learn the stack improve it and work with forward-deployed engineers to package portions of it for deployment with internal and external customers.

• Own the reliability of our agentic infrastructure: agents sessions model routing context pipelines inter-agent communication and supporting services
• Build and maintain infrastructure where good off-the-shelf solutions dont yet exist
• Deploy and operate local LLM inference across Mac Studio and GPU hardware
• Manage Linux/macOS systems Proxmox VMs and containers storage backups and recovery
• Maintain multi-site networking including L3 routing VLANs DNS firewalls and connectivity
• Build CLIs dashboards automation and internal tools that make engineers faster
• Improve observability debugging and automated failure recovery
• Contribute upstream to open-source projects we rely on
• Help design practical security around local compute data handling and access controls
• Package and deploy portions of the stack into internal and customer environments
• Work directly with engineers to understand what they need and turn recurring problems into better infrastructure

About You:

• 5 years of experience building and operating complex software and compute infrastructure with hands-on work across hardware operating systems networking and automation
• Experience deploying an agentic harness such as OpenClaw Hermes SybilClaw or a comparable system in a real work environment
• Strong Linux and macOS systems experience including debugging services processes storage permissions and networking
• Experience operating physical infrastructure VMs or containers in production
• Strong networking fundamentals including routing VLANs DNS and firewalls
• Ability to build software scripts CLIs and integrations when existing tools arent sufficient
• Meaningful experience contributing to or maintaining open-source software
• Strong judgment around reliability security performance and simplicity

Nice to haves but not required:

• Experience with ITAR-regulated air-gapped export-controlled or similarly constrained environments
• Experience operating local LLM inference with Ollama MLX vLLM or similar
• Experience with model routing context management tool execution agent state or multi-agent systems
• Experience building internal developer infrastructure used daily by other engineers
• Experience deploying systems into customer or forward-deployed environments
• A GitHub Gitea or other body of work where we can see what youve built

This role requires in-office presence at least three days per week with flexibility to work remotely when the work allows. Much of this infrastructure is physical local-first and best built alongside the engineers using it.
