Wargamer; Robotics Simulation Engineer

140-190k/yr + equity + benefits | U.S. Persons Only | On-Site in San Francisco, CA

Mara is building a horde of small, autonomous robots to defend the free world. Our first product, Spike, is a portable counter-drone swarm that stops deadly drone attacks
.

We are looking for non-stop builders with a need to be challenged beyond their capabilities daily. If you can’t wait to contribute to the defense of human liberty, apply.

As a Wargamer at Mara, you will be responsible for building and maintaining our simulation infrastructure that trains, validates, and deploys our robots. You'll work with NVIDIA Isaac Sim and other simulation platforms to create high-fidelity environments where our ML models and control systems can iterate s role involves working closely with ML engineers, robotics software engineers, and controls engineers on a regular basis.

You must be stellar at:

• Open and direct communication, whether it's writing up issues, codebase documentation, or face-to-face feedback during a 1:1
• Independently learning new technical skills to unblock yourself mid-build
• Architecting simulation systems that serve multiple stakeholders (ML training, control validation, end-to-end testing)

And completely comfortable with:

• NVIDIA Isaac Sim as your primary simulation environment
• Building custom tools, APIs, and plugins that extend the engine
• Physics simulation, sensor simulation, and rendering at production scale
• Python and C++ for automation and engine extensions
• Real-time performance optimization in simulation
• Sim2
  
  Real workflows: closing the gap between simulation and real hardware
• Managing simulation datasets and training pipelines
• Spotlessly documenting simulation architecture and tooling

Bonus Points for:

• Experience with multiple game engines or simulation platforms
• GPU-accelerated simulation or differentiable simulation
• Personal projects involving UAVs, ML, or robotics
• Open source contributions to simulation or robotics projects
• General awareness of cybersecurity concepts

• Strong proficiency in C++ and Python
• Experience with NVIDIA Isaac Sim, or equivalent robotics simulation platform
• (optional) A degree in Computer Science, Computer Engineering, or a related field

• Building and optimizing simulation environments for training and validation
• Extending Isaac Sim with custom tools, sensor models, and domain-specific plugins
• Developing automation pipelines for data generation and model evaluation
• Collaborating with ML and controls engineers on sim requirements
• Identifying and closing Sim2
  
  Real gaps through iteration and testing
• Building lightweight internal tools to support engineering workflows
• Documenting simulation architecture, data formats, and best practices
• Periodically assisting with real world testing efforts (may involve travel)

Mara is an Equal Opportunity Employer. We will always hire folks from any and every background and lived experience, because we know that’s how the strongest teams in the world are built. Empowerment, equity, and liberation bring strength, resilience, and growth; which is why we believe in the vigorous defense and continuous improvement of the free nations of the world.

Folks of all genders and creeds who are Black, Indigenous, people of color, queer, trans, non-binary, disabled, parents, immigrants, and anyone who has experienced systemic oppression are encouraged to apply.
