Mechanical Design Engineer / Mechanical EngineerLocation: Houston, TXPackage: $110,000 - $140,000 + equityThe 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.ResponsibilitiesLead mechanical design of high-performance components and assembliesBuild and prototype your own concepts using in-house tools, fixtures, and experimental setupsExecute testing (thermal, vibration, structural, performance) and use results to drive design iterationDevelop mechanical architectures for power systems, battery modules, enclosures, packaging, and thermal structuresOwn the full engineering lifecycle: requirements, design, simulation, prototype, validation, releaseCollaborate closely with electrical, thermal, and systems engineers on integrated hardwareSupport flight hardware development and qualificationContribute to rapid development cycles where "test-iterate-test" is the normRequirements5+ years mechanical engineering experience in hardware product developmentStrong 3D CAD capability (SolidWorks, Creo, NX or similar)Proven hands‑on ability to prototype, assemble, instrument, and test your own designsExperience with one or more: power systems, energy storage (battery modules, packs, enclosures), thermal structures / heat transfer, aerospace or high-reliability hardwareComfort working in fast development cycles with limited information and evolving requirementsStrong understanding of materials, manufacturing processes, tolerances, and DFM/DFAMission-critical hardware for spaceflight, defence and advanced grid systemsHigh-performance mechanical assemblies where weight, reliability and thermal behaviour are essential#J-18808-Ljbffr
