Mechanical Engineer

Heaviside Industries, Inc.•Marina del Rey, CA

7d•$120,000 - $150,000•Onsite

About The Position

Heaviside Industries builds multi-domain autonomous precision munitions for U.S. and allied special operations and conventional forces. While modern warfare has rapidly evolved with the proliferation of unmanned systems, hyper-precise munitions in contested environments are the future of the battlefield. Economical precision strike capabilities are critical to U.S. and allied war efforts, enabling successful defeat of enemy military assets and infrastructure. Heaviside builds precision munitions designed to operate in GPS-denied and spectrum-jammed battlefields—where traditional systems degrade or fail—without inflated prices or sacrifice to performance. All engineering and manufacturing is conducted in-house in Heaviside's Los Angeles, CA headquarters and Oslo, Norway office. Heaviside is backed by Felicis, Hedosophia, Interlagos, Friends & Family Capital, Menlo Ventures, Flume Ventures, Cantos, and others.

Requirements

B.S. in Mechanical or Aerospace Engineering, or a closely related field.
1–3 years of hands-on mechanical design experience, full-time or on a serious competition or race team.
Proficiency in 3D CAD and creating production-ready drawings with GD&T.
Working knowledge of machining, sheet metal, composites, or additive processes, and how design choices affect cost and lead time.
Comfort doing structural analysis by hand and with FEA tools.
You've built things with your own hands and enjoy being on the shop floor and at the test site.
U.S. Person as defined by ITAR (22 CFR §120.62)

Nice To Haves

Formula SAE, Baja SAE, Formula Student, Solar Car, or similar competition team experience, especially in a lead role.
Time at a race team, motorsports supplier, or automotive OEM (chassis, suspension, powertrain, aero, or vehicle dynamics).
A personal build: a track car, kit car, motorcycle, or EV conversion you designed or modified yourself.
Hands-on skills: TIG welding, manual or CNC machining, composites layup.
Experience with vibration and shock analysis, data acquisition, or test instrumentation.
Exposure to aerospace, defense, or underwater systems.
An active security clearance, or prior military service.

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 Heaviside's in-house production and RF production 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.
