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 Team

The Astra Test Team is responsible for verifying that flight hardware will successfully operate in space. We execute testing for increasingly high-throughput production of our thruster modules and related subsystems, plus continual development testing for new programs and capabilities. To make this all happen, we also develop and operate state-of-the-art facilities for testing plasma thrusters in conditions that simulate the space and launch environment - high vacuum, thermal, vibration, and shock. 

The Opportunity 

As a Senior Test Systems Engineer at Astra, you'll support all aspects of testing our Astra Spacecraft Engine (ASE) Hall-effect thruster modules—ensuring mission success from ground to orbit. Your responsibilities will span hands-on system and subsystem testing, commissioning and operating test facilities for both R&D and production, and contributing across the entire test lifecycle—from development through qualification and acceptance. You'll also play a key role in mentoring junior engineers and test technicians and helping shape our testing culture.

You’ll thrive in this role if you bring experience from a fast-paced, high-performance environment, and have a strong track record of delivering technically challenging projects while collaborating across diverse engineering teams.

How You'll Fulfill Your Mission

• Prioritize Safety: Work safely around hazards including cryogenics, pressure systems, and heavy equipment—predicting, mitigating, and managing risks to prevent injury.
• Execute Testing: Perform functional and performance tests on flight hardware including plasma thrusters, propellant feed systems, and power electronics.
• Stand Bring-Up: Commission, maintain, and improve advanced test stands, data acquisition systems, and ground test infrastructure.
• Build & Assemble: Fabricate and assemble test fixtures and setups using CAD models, electrical schematics, and mechanical drawings.
• Troubleshoot: Diagnose and resolve electrical and mechanical issues in test setups and hardware systems.
• Document Rigorously: Develop and maintain detailed test procedures, reports, and SOPs to ensure consistency and traceability.
• Mentor & Guide: Support the growth of early-career engineers and test technicians through hands-on coaching and technical leadership.

Why We Value You

• 5+ years of hands-on experience in test engineering, fabrication, or system integration—including hardware/software interface work
• Proficient with bench test equipment: multimeters, power supplies, oscilloscopes, and current/voltage probes
• Experience working with fluid systems, pressure vessels, and related safety protocols
• Skilled in Python and LabVIEW, with experience using NI hardware and data acquisition systems
• Willingness to support critical test operations, including evenings or weekends as needed
• Excited to be part of a team launching real hardware into space
• Bachelor’s degree in Mechanical, Electrical, or Aerospace Engineering—or equivalent hands-on experience in a technical lab or industrial environment

Desired Multipliers 

• Familiarity with space systems and/or vacuum systems
• Experience soldering and crimping wiring harnesses
• Ability to interpret test results and independently design new test plans
• Proactive in suggesting design improvements based on test outcomes
• Ownership mindset—you take pride in the fact that this is your hardware going to space

The pay range for this role is: $150,000 - 185,000 per year

The stated compensation range reflects only the targeted base salary range in the San Francisco Bay Area and excludes additional earnings such as bonus and benefits. If your salary requirements fall outside of the range, we still encourage you to apply.
