E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems. We are seeking a hands-on Test Engineer to join our Guidance, Navigation & Control (GNC) team. You will design, build, and operate testbeds and ground support equipment to validate sensors, actuators, and the end-to-end GNC subsystem. This position is based in Saratoga, CA.

  • Design, assemble, and operate hardware testbeds and ground support equipment (GSE).
  • Develop scripts and tools for test automation, data processing, and logging.
  • Develop and execute characterization, qualification, and acceptance test procedures for GNC sensors, actuators, and for system-level Assembly, Integration, and Tests (AIT).
  • Document test results and process data to support calibration and performance model updates.
  • Participate in spacecraft AIT campaigns, including flat sat and environmental testing, ensuring continuity from subsystem validation through to on-orbit commissioning.
  • Prepare documentation, present findings, and participate in design and test reviews.
  • BS +5 years / MS +3 years in Electronics, Mechatronics, Robotics, Aerospace, or related field.
  • Organized and proactive problem solver; thrives in hands-on fast-paced startup environment.
  • Direct experience testing and delivering critical hardware, with associated processes and practices (clean room, ESD protocols, access controls, etc.).
  • Proficiency with CAD modeling and 3D printing for rapid prototyping.
  • Skilled in Unix/Linux, Bash, Python, MATLAB, and collaborative version control (git-based workflows).
  • Experience building and operating testbeds using microcontrollers or embedded systems (e.g., Raspberry Pi, Arduino, Pixhawk).
  • Familiarity with typical GNC sensors and actuators (e.g., IMUs, GNSS, magnetometers), and associated testing and calibration methods.
  • Excellent technical communication and presentation skills.
  • Experience with a spacecraft AIT, launch campaign, and spacecraft on-orbit operations.
  • Knowledge of GNC estimation (e.g., Kalman filters) and control (e.g., PID, LQR) algorithms.
  • Understanding of space environment effects on hardware.
  • Experience reading PCB schematics, debugging PCBs and building simple harnesses.
  • An opportunity to really make a difference
  • Sustainability at our core
  • Fair and honest workplace
  • Innovative thinking is encouraged
  • Competitive salaries
  • Continuous learning and development
  • Health and wellness care options
