Job description

Senior Software Engineer, Agentic Infrastructure

Long Beach, California, United States

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:

Dark Matter Lab is a research group within Relativity Space focused on advanced aerospace systems, agentic engineering, and technologies outside the conventional roadmap. We 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 day. You’ll 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 don't 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 aren't 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, llama.cpp, 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 you've 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.

At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job‑related factors.

Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more! To see some of the benefits & perks we offer, please visit here.

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service‑connected disability.

A "recently separated veteran" means any veteran during the three‑year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval, or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way.
