About The Position

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.

Requirements

• 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.

Responsibilities

• 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.
