Full Job Description
Responsibilities

We are seeking a Lead Engineer who can bring automation and autonomy to our R&D. A key facet is engineering the physical embodiment of artificial intelligence-translating advanced AI/ML algorithms into robust, fieldable autonomous robotic systems. This role focuses on the hardware implementation of autonomous systems, using advancements in embodied AI to create self-governing systems that have the capability of adapting without human intervention. It requires deep expertise in mechanical engineering, robotics integration, autonomy architectures, and physical/digital test infrastructure development.

The selected candidate will support the design and implementation of integrated robotic platforms, digital twin ecosystems, and laboratory-scale autonomy testbeds that accelerate deployment across air, ground, maritime, subsea, and space domains. This role bridges mechanical design, embedded systems, autonomy software, simulation environments, and sponsor-driven mission needs.

Strategic & Technical Leadership
  • Execute the technical vision for AI-enabled autonomous systems with an emphasis on physical system realization and field transition
  • Lead development of integrated autonomy architectures spanning mechanical systems, sensing, controls, embedded compute, and AI/ML stacks
  • Translate sponsor mission needs into engineered robotic systems and deployable autonomy capabilities
    Establish digital twin and physical prototyping capabilities that accelerate system validation and transition

Mechanical Engineering & Robotic System Development
  • Lead mechanical design and integration of robotic platforms including:
    • Structural systems
    • Actuation and mobility subsystems
    • Power distribution and thermal management
    • Payload integration and sensor mounting architectures
  • Engineer robotic embodiments capable of operating in austere and mission-relevant environments
  • Develop modular hardware architectures to enable rapid prototyping and mission reconfiguration
  • Oversee fabrication, assembly, integration, and validation of robotic platforms
  • Conduct system-level trade studies balancing weight, power, compute, and autonomy performance

Autonomy & AI Integration
  • Design and implement end-to-end autonomy stacks integrating:
    • Perception (EO/IR, LiDAR, IMU, multi-modal fusion)
    • State estimation and navigation
    • Planning and decision-making
    • Controls and low-level actuation
  • Deploy advanced ML architectures onto edge and embedded hardware platforms (e.g., NVIDIA Jetson-class devices)
  • Optimize models for real-time, low-latency operation within power- and compute-constrained robotic systems
  • Develop scalable MLOps pipelines tailored for robotics environments

Digital Twin & Test Infrastructure Development
  • Architect and implement high-fidelity digital twin environments for robotic systems using simulation platforms such as Omniverse, Isaac Sim, Unreal, or equivalent
  • Establish software-in-the-loop (SIL), hardware-in-the-loop (HIL), and human-in-the-loop testing frameworks
  • Design hybrid physical/digital experimentation workflows linking lab hardware with simulation-based validation
  • Develop robotic laboratories and autonomy experimentation facilities capable of supporting multi-domain platforms
  • Build data pipelines for synchronized physical and simulated experimentation
  • Enable rapid iteration between simulated and real-world deployments

Systems Engineering, Test & Evaluation
  • Lead requirements definition, verification, validation, and accreditation (VV&A)
  • Execute Test & Evaluation (T&E) for fieldable systems under sponsor constraints
  • Conduct performance characterization of mechanical, electrical, and autonomy subsystems
  • Ensure systems meet safety, cybersecurity, and compliance requirements for defense applications
  • Lead integration and demonstration efforts during on-site DoD test events

Research, Funding & Mentorship
  • Support internal R&D investments in robotic autonomy and physical AI systems
  • Author and contribute to proposals, journal publications, technical reports, and patent disclosures
  • Sustain and grow sponsor-funded programs
  • Mentor junior engineers in mechanical design, robotics integration, and autonomy development


This position is based in Richland, WA and requires onsite engagement with robotic laboratories and hardware development environments.
