This is an emerging defense technology startup building counter-UAS applications. The company is focused on platforms designed to neutralize threats in real-time using precision beam-control and automated targeting technology.

Role Overview

This is a hands-on mechanical engineering role focused on thermal management, structural analysis, and field-deployable hardware for defense-grade systems. The ideal candidate will bring experience in mechanical simulation, vibration and shock testing, thermal system optimization, and prototype fabrication. The role spans early-stage design through manufacturing readiness, with a strong emphasis on iterative testing in harsh conditions.

Key Responsibilities

  • Develop thermal management solutions (active and passive) for high-power modules
  • Run conjugate heat transfer simulations and transient thermal analyses to validate performance
  • Perform FEA simulations for stress, vibration, modal, and impact response
  • Use tools like ANSYS or SolidWorks Simulation to optimize for strength, weight, and field durability
  • Design components and assemblies in CAD (SolidWorks, Creo, etc.)
  • Rapidly prototype hardware using CNC machining, additive manufacturing, or other fabrication methods
  • Plan and execute vibration, shock, and environmental tests to validate field-worthiness
  • Build and deploy test rigs to simulate real-world deployment environments
  • Conduct DFM reviews to ensure components are production-ready and cost-effective
  • Select appropriate materials and tolerances for scalable production with external vendors
  • Analyze metals, polymers, and composites for strength, EMI compatibility, and thermal conductivity
  • Plan mechanical and environmental qualification tests as needed
  • Generate BOMs, GD&T drawings, and assembly documentation
  • Support prototype-to-production handoff with clear, test-validated deliverables
  • Work closely with electrical, firmware, optical, and control teams to ensure full-system integration
  • Support assembly, alignment, and testing in lab and field environments

Qualifications

  • 2–8 years of experience in mechanical, aerospace, or hardware engineering (defense or ruggedized products preferred)
  • Strong CAD skills (SolidWorks, Creo, or similar)
  • Proficiency in FEA tools (ANSYS, SolidWorks Simulation)
  • Hands-on prototyping background and experience building functional mechanical systems
  • Expertise in thermal analysis and simulation (CFD, thermal modeling tools)
  • Experience with vibration, shock, or environmental qualification testing
  • Solid understanding of stress analysis, materials science, and manufacturing processes
  • BS or MS in Mechanical Engineering, Aerospace Engineering, or a related discipline

Nice to Have

  • Experience with environmental chambers or vacuum testing
  • Familiarity with laser safety standards and optical/mechanical alignment
  • Background in EMI/EMC shielding and rugged electronics packaging
  • ITAR experience or eligibility for U.S. security clearance
