About the Job

Requirements

  • A B.S. in Computer Engineering, Electrical Engineering, Computer Science, or a related field is required.
  • At least 5 years of embedded systems experience, including work on fielded hardware, is required.
  • Strong C and C++ skills, plus Python or Bash for tooling and automation, are required.
  • Hands-on experience developing embedded software, including device drivers, hardware bring-up, and embedded build tools, is required.
  • Experience integrating sensors over common interfaces such as Ethernet, CAN, UART, SPI, and I2C is required.
  • Experience designing watchdogs, health monitoring, or fault handling for systems that must run unattended is required.
  • Comfort with lab equipment such as oscilloscopes and logic analyzers, and with reading schematics, is required.
  • Comfort working in the lab and in the field alongside hardware, software, and test teams is required.
  • Willingness to travel up to 50% of the time when needed is required.
  • U.S. person status, as defined by 22 CFR 120.62, is required for access to ITAR/EAR-controlled data.

Responsibilities

  • Develop and maintain embedded software on onboard vehicle computers, including board support packages, device drivers, boot configuration, and system services.
  • Integrate sensors and I/O, including IMUs, GNSS receivers, radar, cameras, and payloads, over interfaces such as Ethernet, CAN, serial, SPI, and I2C.
  • Manage time synchronization and timestamping across sensors and compute, such as PTP and PPS, so autonomy and GNC receive accurate data.
  • Build health monitoring, watchdogs, and fault detection that report system status and trigger safe behavior when components fail.
  • Implement fail-safe and degraded-mode behaviors for uncrewed operation with the GNC, autonomy, and systems teams.
  • Harden onboard systems, including secure boot, access control, and reliable field software updates.
  • Profile and optimize performance, latency, and resource use on constrained hardware.
  • Bring up new hardware with the electrical team, and debug issues on the bench, in hardware-in-the-loop setups, and in the field.
  • Document interfaces, configurations, and procedures.

Desired Qualifications

  • Experience with NVIDIA Jetson or similar edge compute platforms.
  • Experience with real-time operating systems on microcontrollers or embedded processors.
  • Familiarity with time synchronization, including IEEE 1588 PTP and GNSS PPS.
  • Experience running ROS 2 or DDS on embedded targets.
  • Knowledge of secure boot, system hardening, or cybersecurity requirements for defense systems.
  • Eligibility to obtain a U.S. Secret or higher security clearance; an active clearance is not required.
  • Experience with marine electronics standards such as NMEA 0183 or NMEA 2000, or with harsh-environment systems.
  • Background with uncrewed or autonomous vehicles.
