What this job asks for AI summary
A stealth-mode robotics startup is hiring a software engineer to own simulation infrastructure and model deployment for a fleet of 100 humanoid robots. The role centers on building and maintaining high-fidelity simulation environments (Newton, MuJoCo), working with robot URDFs and retargeting pipelines, and deploying trained world models to real hardware. It suits engineers with prior hands-on simulation experience in robotics domains such as self-driving, humanoid, cobot, or industrial platforms.
Senior level
We read this from the posting text with AI. Skim the description below before ruling yourself out.
Why we read it this way (8)
Location is not stated in the posting — CBSA and state are left blank. The role may be on-site at an undisclosed stealth-mode company; remote status is assumed false given the physical-robot fleet context, but this is a judgement call.
The posting names Newton (NVIDIA's robotics simulation framework) as a hard requirement alongside MuJoCo; both are listed under 'You Should Have'.
'Robot URDF' and retargeting workflows are listed as required but represent a domain-specific file format/workflow rather than a standalone commercial tool — included as a named technical requirement.
Model deployment and fleet management for physical robots appear only under 'Nice to Have', so they are marked preferred.
Experience at NVIDIA or Google on robotics/simulation teams and familiarity with humanoid platforms specifically are also listed under 'Nice to Have' — these are not emitted as discrete skills since they describe employer background rather than a concrete technology.
No compensation, employment type, or degree requirement is stated in the posting.
SOC confidence is Medium: robotics simulation engineering sits at the intersection of software development (15-1252) and specialized robotics/embedded systems work (15-1299); the primary deliverable is production software, so 15-1252 is the stronger fit.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): fleet management.
