The Role
Own ground testing for large deployable antenna structures, including test requirements, procedures, fixture development, deployment execution, instrumentation, data analysis, anomaly investigation, and reporting. Design and characterize gravity-offload systems, measure forces, motion, timing, and deployed geometry, and assess repeatability. Collaborate with mechanism and structures teams to correlate test results with deployment models and distinguish hardware behavior from ground-test artifacts.
Summary Generated by Built In
Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place!
E-Space is bridging Earth and space to enable hyper-scaled deployments of Internet of Things (IoT) solutions and services. We are building a highly-advanced low Earth orbit (LEO) space system that will fundamentally change the design, economics, manufacturing and service delivery associated with traditional satellite and terrestrial IoT systems.
We’re intentional, we’re unapologetically curious and we’re 100% committed to innovate space-based communications and deliver actionable intelligence that will expand global economies, protect space and our planet and enhance our overall quality of life.
We are looking for a hands-on Mechanical Test Engineer to own ground testing of the physical unfolding of E-Space’s large deployable antenna structure. You will work with deployable structures, deployment mechanisms, test fixtures, and gravity-offload equipment: building test setups, operating hardware, measuring its motion and forces, and investigating unexpected behavior.
You will turn hardware observations into evidence that the antenna can deploy reliably and reach its required geometry. This role calls for mechanical intuition, careful experimentation, and the ability to distinguish the behavior of the antenna from effects introduced by the ground test equipment.
On-site in Arlington, Texas. Hands-on bench work and test facility presence are required. Some travel between sites expected.
What you will do:
- Own the antenna assembly’s mechanical deployment test program, from test requirements and procedures through fixture development, test execution, data reduction, and reporting.
- Design, build, and improve gravity-offload and support fixtures for large flexible structures. Characterize rig friction and compliance so their effects can be separated from antenna behavior.
- Set up and run physical deployment tests. Measure force and torque profiles, boom tip trajectories, deployment timing, and deployed shape using appropriate instrumentation and optical measurement methods.
- Investigate unexpected motion, inconsistent deployment, and geometry outliers through inspection, measurements, and controlled follow-up tests.
- Establish deployment repeatability against defined requirements, and characterize sensitivity to sequencing, temperature, and lubricant state where required by the test plan.
- Work with the deployment mechanism team to characterize actuator output and locked-state stiffness and backlash.
- Coordinate subsystem testing and assembly-level deployment testing with the responsible engineers.
- Work with the IAS structures analyst to correlate test results with the structural and deployment models, quantify ground-test artifacts, and bound what the results establish about flight deployment.
Required qualifications:
- BS, MS, or PhD in Mechanical or Aerospace Engineering, or equivalent practical engineering experience.
- Hands-on experience testing physical mechanisms or deployable hardware, with clear examples of personally setting up, operating, measuring, and troubleshooting hardware.
- Practical mechanical judgment: able to reason about forces, motion, friction, stiffness, alignment, and the influence of a test fixture on the hardware being measured.
- Experience developing test procedures and using force, torque, motion, or optical measurement instrumentation to obtain repeatable data.
- Ability to investigate an anomaly systematically and explain what the evidence supports, what remains uncertain, and what to test next.
- Understanding that a ground test under gravity does not automatically reproduce flight deployment conditions.
Preferred qualifications:
- Deployment testing of antennas, solar arrays, booms, or other flexible flight structures.
- Design or operation of gravity-offload rigs, including characterization of friction and support compliance.
- Experience with deployable booms (rollable, telescoping, hinged, or coilable lattice) and membrane or other tensioned deployable hardware.
- Photogrammetry or other optical measurement of deployed shape and motion.
- Experience with mechanism friction and lubrication across temperature ranges, thermal-vacuum deployment tests, or deployment model-test correlation.
Additional Requirements
This is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.
This is a full time, exempt position, based out of our Arlington, TX office. The total compensation packaged will be determined by various factors such as your relevant job-related knowledge, skills, and experience.
We are redefining how satellites are designed, manufactured and used—so we’re looking for candidates with passion, deep knowledge and direct experience on LEO satellite component development, design and in-orbit activities. If that’s your experience – then we’ll be immediately wow-ed.
E-Space is not currently able to provide employment sponsorship for candidates who do not hold work authorization for the location of this role.
