Senior Mechanical Engineer

**Applicants must be U.S. Citizens or U.S. Permanent Residents (Green Card holders) to meet customer and regulatory requirements** Who We Are We are pioneering modular motion technologies to power the next generation of innovation for Industrial, Aerospace and Defense. If you're excited about disrupting legacy industries, and passionate about motor control technology, let's chat! We are at the forefront of innovation, crafting exclusive motion control components that propel the industrial, aerospace, and defense sectors into the future. A couple other things: We are open to relocating you We have great benefits We are well funded, and already generating revenue We are located in beautiful Hawthorne, CA and just moved into a new large hangar facility What you'll do: We are seeking a versatile, high-impact Engineer to lead the development of mission-critical hardware. This is a "full-lifecycle" role where you will own everything from the initial conversion of ambiguous concepts into rigorous requirements to the hands-on assembly and environmental qualification of flight hardware. Requirements Architecture: Translate high-level, ambiguous mission needs into actionable functional and operational requirements for complex electromechanical systems. Precision Mechanism Design: Design and iterate on electromagnetic actuators and intricate mechanisms, integrating components such as precision gears, bearings, lead screws, braking systems, and encoders. Ruggedized Avionics: Develop high-performance avionics enclosures, focusing on innovative thermal management (heat rejection) and structural survivability in extreme, high-vibration, or vacuum environments. Environmental Qualification: Architect the test equipment and methodologies required for formal hardware qualification, ensuring total compliance with DO-160 and MIL-STD-810 standards. Cross-Functional Leadership: Act as a technical anchor across the organization, guiding integration efforts and supporting multidisciplinary teams through complex system testing. Supply Chain & Quality Advocacy: Partner closely with external suppliers to ensure the delivery of conforming hardware; proactively manage manufacturing deviations to maintain rigorous quality and schedule standards. Hands-on Execution: Maintain a "design-build-test" mindset, taking personal responsibility for the assembly, bring-up, and debugging of your own hardware prototypes. What you need: Education: Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related technical discipline. Experience: 5+ years of experience through the full product lifecycle—from initial ideation and prototyping to high-fidelity production. Technical Expertise: A deep intuition for electromagnetic principles and a mastery of mechanical load paths and load cases. Analysis & Simulation: Proficiency in sizing analysis for strength, fatigue, and life cycles of actuator components (gears, shafts, housings). <li data-leveltext="" data-font="Symbol" data-listid="8" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="5" data-aria-level=
