Mechanical Design Engineer

We’re supporting a rapidly growing technology company at the forefront of space systems, advanced energy storage, grid technology, and defense applications. This innovative company develops cutting-edge solutions that push the boundaries of performance and reliability, addressing critical needs in mission-critical environments across various industries.

Mechanical Engineer / Mechanical Design Engineer

Location: Houston, TX
Level: 5+ years’ experience

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
Commutable or local to Houston, TX
