Lead structural dynamics analysis, verification, and model validation for satellites to ensure survivability through launch and thermal cycling in a clean energy technology company.
О компании
- Overview Energy is a mission-driven team committed to building a new layer of energy infrastructure: satellites in geosynchronous orbit that redirect solar energy to terrestrial solar projects via passively safe near-infrared (NIR) light. We're in the earliest phase, where every structure we launch is analyzed, tested, and proven end-to-end by a small, dedicated team. Headquartered in the Northern Virginia / Washington, DC area and backed by world-class investors, we are advancing the next generation of clean energy technology.
Обязанности
- We're hiring a Structural Dynamics Lead to build Overview Energy's structural analysis, verification, and model validation capability from scratch. You'll bring structural dynamics fully in-house, replacing work we currently send to outside contractors.
- Every structure we put into orbit has to survive launch and years of thermal cycling. Your analysis is what stands between a design and a satellite that fails silently nearly 36,000 km away. Get it right, and solar farms already on the ground keep producing power after dark.
- Working daily in our Ashburn, VA office, you'll work alongside our structural, optics, mechanisms, and systems engineering teams. You'll run the simulations, define the tests, build the fixtures, and command the room when the shaker table turns on. Along the way, you'll build the tools, procedures, and test capability this practice runs on for years to come.
- Build Nastran models from scratch for the primary structure, deployables, and the structure holding our optics
- Own loads and margins of safety for every flight structure, from launch vibration and shock to bolted joints
- Deliver Craig-Bampton models to launch providers and interpret the coupled loads results that come back
- Define static and dynamic test requirements: levels, durations, notching, sensor placement, and pass criteria
- Design and survey test fixtures, run test campaigns in person, and process the data yourself
- Correlate every model to test data and recommend design changes before hardware is released
- Predict how thermal cycling stresses our structures and correlate it to strain data from thermal tests
- Supply thermal distortion results to the optics team for Structural Thermal Optical Performance (STOP) analysis
- Write the analysis standards and validation procedures the next analyst inherits
Требования
- A bachelor's degree in Mechanical, Aerospace, or Structural Engineering
- 5-10 years of structural analysis experience on flight hardware: spacecraft, launch vehicles, or aircraft
- Hands-on experience across the full analysis cycle on multiple flight structures: build the model, define the test, correlate, and recommend the fix
- Expertise in Nastran structural dynamics (sine, random, and shock) using Femap, Patran, or Simcenter 3D
- Experience defining static and dynamic test requirements and designing the fixtures to run them
- Hands-on Siemens NX experience, from preparing geometry for analysis to modeling test fixtures
- This position is subject to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR). Candidates must be a U.S. citizen, lawful permanent resident, protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
Условия
- The salary range for this position is $120,000 - $170,000 commensurate with experience. Individuals with demonstrated exceptional ability may be considered beyond this band.
- We take care of our people. In addition to competitive salary and equity, Overview Energy offers comprehensive medical, dental, vision, disability, and life insurance coverage, a health and wellness stipend, 4 weeks paid time off, 2 weeks sick leave, parental leave, and 401(k) matching. Benefits are subject to change at the Company's discretion.

- Experience with thermal distortion or STOP analysis on optical systems
- Proficiency in Python or MATLAB for Nastran post-processing and test data reduction
- Familiarity with GEVS, NASA-STD-5001, SMC-S-016, or launch-provider structural requirements
- A record of trading mass against stiffness on satellite structures, backed by GD&T and DFM/DFA
