Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of Relativity Space as an employer.

What you need

  • 5+ years of experience building and operating complex software and compute infrastructure
  • 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

Nice to have

  • 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

What you get

  • Competitive salary and equity
  • Generous PTO and sick leave policy
  • Parental leave
  • Annual learning and development stipend

Worth weighing

  • In-office presence required at least three days per week
  • Compensation is based on experience and qualifications, with a stated range of $154,000 to $230,000
  • Much of the infrastructure is physical and local-first, which may limit remote work opportunities
