Astra Spacecraft Engine Test Technician

Astra's mission is to improve life on Earth from space by creating a healthier and more connected planet. Today, Astra offers one of the lowest cost-per-launch dedicated orbital launch services, and one of the industry's leading flight-proven electric propulsion systems for satellites, the Astra Spacecraft Engine.

The Opportunity

As a Test Technician at Astra, you will play a hands-on role in testing our Astra Spacecraft Engine (ASE) Hall-effect thruster modules in vacuum environments that simulate space conditions. You'll be responsible for preparing, operating, and maintaining vacuum chambers, assembling test setups, and supporting 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.

How You'll Fulfill Your Mission

• 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 testsincluding 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

Why We Value You

• 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
• You take pride in high-quality, detail-oriented work
• High school diploma or GED required; technical certification or associate degree in a related field preferred

Desired Multipliers

• 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
