Job description

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, defense and advanced grid systems

High-performance mechanical assemblies where weight, reliability and thermal behavior are essential
