Full Description

🛰 Environmental Test Engineer – Vibration & TVAC | Space Systems

Are you passionate about building hardware that survives launch and thrives in orbit?

We’re supporting a space company that’s building the first and only global cellular broadband network in space, enabling standard mobile phones to connect directly to satellites- no ground infrastructure needed.

They’re hiring an Environmental Test Engineer to join their mission. You'll be hands-on with shakers, TVAC chambers, data systems, and high-stakes flight hardware, verifying spacecraft components through vibration and thermal vacuum testing. This role is perfect for someone who wants to work cross-functionally, build out cleanroom test setups, and ensure mission-critical systems survive launch and space.

You’ll be doing

Writing and executing test plans for vibration (sine, random, shock) and TVAC testing
Setting up and calibrating shakers, vacuum chambers, thermal instrumentation, and DAQ systems
Collaborating with design, manufacturing, and systems engineering to define test requirements
Monitoring and troubleshooting test campaigns in real time
Leading root cause investigations when anomalies occur
Producing detailed test reports (including data, plots, and pass/fail assessments)
Driving continuous improvement across environmental test processes and infrastructure

You’ll need

3+ years of experience in space or defense environmental testing
Strong hands-on background with shakers, TVAC chambers, accelerometers, and thermal sensors
Familiarity with MIL-STD-1540, NASA GEVS, ECSS, or related standards
Solid understanding of test instrumentation, fixturing, and contamination control
Engineering degree (Mechanical, Aerospace, or similar)

Bonus points for

Experience with LabVIEW, TestStand, MATLAB, or Python for automation and data analysis
Satellite or launch vehicle campaign experience
Cleanroom discipline and high-reliability mindset

📍 Location: Onsite role in Texas (relocation supported)
