Job Description

Test Engineer – Hands-On Role in Next-Generation Propulsion Development!

El Segundo, CA | Onsite

Opportunity Summary

We are a venture-backed, pre-seed stage startup developing advanced propulsion technologies for spacecraft. With active government contracts and strategic partnerships, our small but fast-moving team is building hardware from the ground up to enable more efficient, scalable in-space mobility. As our first dedicated Test Engineer, you will work directly with the CEO and CTO in a hands-on lab environment to design, build, and execute experimental test campaigns. This role is ideal for someone who thrives on solving problems creatively, developing test systems with limited resources, and wearing multiple hats across electronics, mechanical, and software domains. You’ll play a critical role in validating propulsion hardware, shaping experiments, and ensuring our systems perform under real-world conditions.

About Us

We are an early-stage propulsion company focused on enabling the next generation of spacecraft mobility. Our systems are designed for high-efficiency performance, with applications spanning both commercial and defense missions. With deep aerospace and defense expertise, active government contracts, and a lean, mission-driven team, we are positioned to rapidly advance propulsion technology from lab-scale demonstrations to flight-ready hardware.

Job Duties

• Develop and execute test plans for propulsion hardware, subsystems, and components.
• Operate and maintain laboratory test setups, including vacuum chambers, pumps, gauges, and sensors.
• Build and configure hardware test rigs, integrating mechanical and electrical subsystems.
• Program and automate test setups using Python, Arduino, or similar tools.
• Conduct hands-on work with machining tools (e.g., drilling, modifying fixtures) to enable rapid prototyping.
• Design and assemble circuits, integrate sensors, and troubleshoot electronics in support of tests.
• Collect, analyze, and report experimental data for leadership and partners.
• Collaborate closely with the CEO and CTO to define technical milestones and adapt to evolving requirements.
• Work flexibly across different test environments and equipment, often under resource constraints typical of startups.
