Mechanical Design Engineer / Mechanical Engineer
Location:
Houston, TX
Package:
$110,000 - $140,000 + equity
The team is building hardware that must perform flawlessly in mission-critical environments - and they’re looking for a Mechanical Engineer who is comfortable owning full product development from concept through to flight-ready hardware.
This is a hands‑on engineering role. You will design, prototype, test, break, iterate, refine, and ultimately ship real hardware that pushes the boundaries of performance and reliability.
Responsibilities
- Lead mechanical design of high-performance components and assemblies
- Build and prototype your own concepts using in-house tools, fixtures, and experimental setups
- Execute testing (thermal, vibration, structural, performance) and use results to drive design iteration
- Develop mechanical architectures for power systems, battery modules, enclosures, packaging, and thermal structures
- Own the full engineering lifecycle: requirements, design, simulation, prototype, validation, release
- Collaborate closely with electrical, thermal, and systems engineers on integrated hardware
- Support flight hardware development and qualification
- Contribute to rapid development cycles where "test-iterate-test" is the norm
Requirements
- 5+ years mechanical engineering experience in hardware product development
- Strong 3D CAD capability (SolidWorks, Creo, NX or similar)
- Proven hands‑on ability to prototype, assemble, instrument, and test your own designs
- Experience with one or more: power systems, energy storage (battery modules, packs, enclosures), thermal structures / heat transfer, aerospace or high-reliability hardware
- Comfort working in fast development cycles with limited information and evolving requirements
- Strong understanding of materials, manufacturing processes, tolerances, and DFM/DFA
- Mission-critical hardware for spaceflight, defence and advanced grid systems
- High-performance mechanical assemblies where weight, reliability and thermal behaviour are essential
