Principal Aeronautical Engineer

Heaviside Industries; Los Angeles (CA); On-site; USD 180,000 - 260,000; Full time

Job summary

Heaviside Industries, based in Los Angeles, is seeking an experienced Senior Aerodynamics Engineer to own airframe design across launch, cruise, and terminal flight. You will drive analyses with CFD and wind tunnel data and build robust aero databases for 6-DOF weapons simulation.

We expect 10+ years in missiles or military aviation, with hands-on design-to-flight-test ownership and wind tunnel planning. ITAR considerations apply; this is an on-site role in Los Angeles.

Qualifications

• 10+ years of aerodynamics or flight sciences experience on missiles, munitions, military UAS, or tactical aircraft.
• Ownership of an air vehicle's aerodynamic design from concept through flight test.
• Proficiency in CFD (STAR-CCM+, Fluent, OpenFOAM) and low-order aero-prediction tools (Missile DATCOM, AVL).
• Strong foundation in flight mechanics, stability and control, and aero databases for 6-DOF weapon simulation.
• Experience with wind tunnel test planning, execution, and data reduction.
• U.S. Person as defined by ITAR (22 CFR 120.62).

Responsibilities

• Own the aerodynamic design of Heaviside's munition airframes across launch, cruise, and terminal flight.
• Lead aerodynamic analysis from conceptual sizing through detailed design using CFD and wind tunnel data.
• Develop and maintain vehicle performance models—range, endurance, dash speed, and terminal maneuver.
• Generate stability and control derivatives and aero databases for GNC design.
• Lead propulsion-airframe integration for electric and small air-breathing propulsion.
• Plan and execute aerodynamic test campaigns: wind tunnels, flight tests, and parameter identification.
• Mentor engineers and set the technical standard for analysis quality.

Job description

About Heaviside Industries

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.

What You Will Do

• Own the aerodynamic design of Heaviside's munition airframes: configuration development, airfoil and planform selection, and performance optimization across launch, cruise, and terminal flight.
• Lead aerodynamic analysis from conceptual sizing through detailed design using low-order methods and CFD, anchored by wind tunnel and flight test data.
• Develop and maintain vehicle performance models — range, endurance, dash speed, and terminal maneuver capability — that drive design trades and customer commitments.
• Generate stability and control derivatives and aerodynamic databases for GNC design, including folding-surface deployment transients and tube-launch separation aerodynamics.
• Lead propulsion-airframe integration for electric and small air-breathing propulsion, including propeller/motor performance matching.
• Plan and execute aerodynamic test campaigns: wind tunnel entries, instrumented flight tests at DoD ranges, and parameter identification.
• Mentor engineers across the vehicle design team and set the technical standard for analysis quality.

What We Are Looking For

• 10+ years of aerodynamics or flight sciences experience on missiles, munitions, military UAS, or tactical aircraft — with hardware that flew.
• Demonstrated ownership of an air vehicle's aerodynamic design from concept through flight test.
• Expert proficiency in CFD (e.g., STAR-CCM+, Fluent, OpenFOAM) and low-order aero-prediction tools (e.g., Missile DATCOM, AVL), with sound judgment on when each is appropriate.
• Strong foundation in flight mechanics, stability and control, and the generation of aero databases for 6-DOF weapon simulation.
• Experience with wind tunnel test planning, execution, and data reduction.
• Working fluency in performance analysis for small, fast, or long-endurance tactical air vehicles under real employment constraints.
• [BONUS] Experience with high-subsonic/transonic munition aerodynamics or folding/tube-launched configurations.
• [BONUS] Experience correlating CFD and flight test data through parameter identification on defense programs.
• U.S. Person as defined by ITAR (22 CFR 120.62)
