Full Job Description
**Applicants must be U.S. Citizens or U.S. Permanent Residents (Green Card holders) to meet customer and regulatory requirements**

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).
  • CAD Mastery: Advanced design experience in SolidWorks (or equivalent 3D modeling packages), including complex assemblies and configuration management.
  • Manufacturing & GD&T: Fluency in ASME Y14.5 GD&T standards; ability to produce high-quality 2D drawings and collaborate with vendors to solve DFM (Design for Manufacturing) hurdles.
  • Standards & Qualification: Proven track record of qualifying hardware against rigorous aerospace or military standards (DO-160, MIL-STD-810).
  • Grit: A "builder" mindset-you are as comfortable at a computer as you are in the lab spinning wrenches and debugging your own hardware.

Nice to have:
  • Qualification: Experience designing custom test equipment, writing formal procedures, and executing complex qualification test campaigns.
  • Gearbox Specialization: Detailed knowledge of AGMA Standards, gearbox design analysis (ratios, backlash, lubrication), and specialized fabrication methods.
  • Process Versatility: Experience navigating both high-compliance, "heavy" programs and fast-paced, lean R&D environments.


What we have to offer:

We are not just building components. We are reshaping the future of the Aerospace and Defense component industry, which is a $300B+ market! Come join us and help build next generation systems that will make a massive impact at global scale.
  • We offer competitive compensation: $160,000 to $190,000 base salary + equity
  • Exceptional healthcare benefits, Medical is 100% covered by the company
  • Flexible PTO
  • 401K
  • More to come!
