Job summary

Heaviside Industries, based in Los Angeles, develops multi-domain autonomous precision munitions for U.S. and allied forces. The role centers on owning mechanical design from concept to production, with in-house manufacturing and rigorous GD&T standards.

You will lead structural analysis, optimize airframes for launch/shock and extreme temperatures, and drive manufacturability across composites and metals while mentoring engineers.

Qualifications

• 10+ years mechanical design experience in defense or aerospace hardware with products reaching flight or production.
• Ownership of complete mechanical subsystems: requirements, design, analysis, qualification test, and production release.
• Expert 3D CAD proficiency (NX preferred; SolidWorks or CATIA acceptable) and rigorous GD&T per ASME Y14.5.
• Strong structural analysis capability, including FEA (Nastran, ANSYS, Abaqus) validated against test.
• Hands-on experience with composite and machined-metallic airframe design and fabrication methods.
• Experience qualifying hardware to MIL-STD-810 environments, including shock and vibration.

Responsibilities

• Own the mechanical design of munition airframe structures, mechanisms, and payload packaging from concept through production at Heaviside's in-house LA factory.
• Lead structural design and analysis - hand calculations and FEA - for airframes subject to launch loads, flight loads, and terminal conditions.
• Design for the tactical environment: gunfire/launch shock, vibration, thermal extremes, and moisture per MIL-STD-810, with qualification campaigns to prove it.
• Drive design-for-manufacture across composites, machined metallics, and additive processes, working directly with in-house production and RF teams on integrated builds.
• Own thermal management design for dense avionics and RF payload packaging in small tactical airframes.
• Develop single-use-reliability mechanisms: wing/fin deployment, tube-launch separation, folding aerosurfaces, and actuation systems.
• Release production-ready drawing packages with rigorous GD&T per ASME Y14.5, and mentor engineers across the mechanical team.
