Test Technician

About the Role As a Test Technician at Astra, you will play a hands-on role testing the Astra Spacecraft Engine (ASE) Hall‑effect thruster modules in vacuum environments that simulate space conditions. You will prepare, operate, and maintain vacuum chambers, assemble test setups, and support critical R&D and production test campaigns. This is a highly technical, safety-focused role that requires attention to detail, mechanical and electrical aptitude, and a strong desire to work on systems that will operate in space. What You'll Do

• Operate vacuum chambers: Safely operate and monitor thermal vacuum systems, ensuring test environments meet mission requirements for pressure, cleanliness, and thermal control.
• Test support: Assist in setup, execution, and teardown of propulsion system tests—including thrusters, feed systems, and support electronics.
• Troubleshoot issues: Diagnose and resolve problems with test hardware, instrumentation, and vacuum systems in real time during test operations.
• Assembly & fabrication: Assemble mechanical and electrical test setups from engineering drawings and schematics.
• Maintain systems: Perform routine maintenance and troubleshooting of vacuum hardware, pumps, and instrumentation.
• Safety first: Follow safety protocols around high voltage, pressure systems, and hazardous materials.
• Data logging & documentation: Support test execution by logging data, completing checklists, and ensuring proper documentation of procedures and outcomes.
• Cross-team collaboration: Work closely with test engineers, software developers, and manufacturing technicians to ensure smooth and safe test operations. What We're Looking For
• 2+ years of hands-on experience working in test labs or with vacuum systems, mechanical assemblies, or high-voltage systems.
• Proven troubleshooting skills in electrical, mechanical, or vacuum systems.
• Experience operating or supporting vacuum chamber testing, especially in a space/aerospace environment.
• Comfortable using multimeters, pressure gauges, and other diagnostic tools.
• Familiarity with basic electrical schematics and mechanical drawings.
• Willingness to work non-standard hours (evenings/weekends) as needed to support mission-critical testing.
• High school diploma or GED; technical certification or associate degree in a related field preferred.
• The ability to think critically, troubleshoot under pressure, and adapt quickly to evolving test conditions. Nice to Have
• Experience working with thruster or propulsion system testing.
• Familiarity with cleanroom procedures, vacuum safety, or contamination control.
• Basic skills in soldering, wiring, or fabrication.
• Understanding of pressure systems, cryogenics, or high-voltage safety.
• The ability to think critically, troubleshoot under pressure, and adapt quickly to evolving test conditions. Compensation & Benefits
• Salary: $40 - $50 per hour (USD), targeted base pay in the San Francisco Bay Area; excludes bonus and benefits.
