Senior Onboard Robotics Sensor & Systems Engineer

Gram Games; El Segundo (CA); On-site; USD 180,000 - 220,000; Full time

Job summary

GRAM is seeking a hardware-centered engineer to own the architecture and integration of onboard sensing, compute, and communications for insectoid machines. You will specify sensor suites, compute placement, and interfaces, coordinating across mechanical, electrical, and software domains on benches and assembled machines.

Based in El Segundo, this role requires real-time software responsibility and strong C++/Python skills with experience integrating cameras, lidar, IMUs, and buses such as

Qualifications

• Experience integrating multi-sensor robots with custom hardware and real-time software.
• Selected and integrated cameras, lidar or ranging sensors, IMUs, encoders, force or contact sensing, compute modules, or comparable onboard subsystems using quantitative requirements and interface documentation.
• Proficiency in C++ or Python on Linux with experience in device integration, structured telemetry, calibration, and at least one real-time bus or network such as CAN, EtherCAT, Ethernet, or SPI.

Responsibilities

• Define the onboard sensing, compute, and communications architecture, including sensor coverage, compute placement, network topology, power allocation, and subsystem partitioning.
• Select cameras, lidar and ranging sensors, IMUs, encoders, contact and force sensors, compute modules, and interface devices against field of view, accuracy, rate, latency, bandwidth, power, thermal, environmental, and packaging constraints.
• Define and maintain mechanical, electrical, and software interface contracts across mounts, alignment datums, connectors, pinouts, power rails, buses, network protocols, coordinate frames, data schemas, and configuration parameters.
• Establish end-to-end timing, timestamping, synchronization, latency, bandwidth, and calibration chains across sensing, compute, embedded nodes, and downstream consumers.
• Integrate released boards, sensors, compute, harnesses, mounts, drivers, middleware, configuration, and telemetry into working onboard subsystems, writing C++ or Python integration code where required.
• Diagnose interaction faults such as dropped frames, clock drift, bus saturation, power transients, grounding noise, calibration mismatch, thermal throttling, connector intermittency, and configuration incompatibility.
• Maintain a versioned compatibility and calibration record that connects each subsystem configuration to its firmware, drivers, physical interfaces, measured timing, and known limitations.
