Senior Electrical Engineer - Weapons

San Diego, CA | Engineering | In office | Full-time

At Firestorm, we are building the future of expeditionary defense manufacturing and autonomous systems. Modern conflict has exposed a fundamental problem: the systems needed most by operators are often too expensive, too slow to produce, and too difficult to sustain estorm exists to change that. We develop mission-adaptable aerial systems and deployable manufacturing infrastructure designed to put capability directly into the hands of the warfighter.

From modular unmanned aircraft to xCell – our deployable microfactory – our goal is to make defense systems rapidly deployable, adaptable, and producible at the point of need.

We are looking for builders, operators, and problem-solvers who want to work on meaningful technology with real-world impact.

Firestorm is building next-generation, deployable combat systems, and we’re looking for a Senior Electrical Engineer to join our Munitions Group. In this role, you’ll own the electrical design, integration, test, and certification of Electronic Safe-and-Arm Devices (ESAD) and Electronic Safe-Arm-and-Fire (ESAF) systems across our tactical sUAS platforms—ensuring every effector stays inert until intentionally armed, functions reliably on command, and remains compliant from concept through field deployment.

This role sits at the heart of how our munitions are made safe. You’ll architect and integrate the firing electronics, energy storage and management, environmental sensing, and arming logic that keep weapons inert until the right conditions are met—then deliver precise, repeatable function on command. Your day may involve schematic capture and PCB layout for a proposed firing set; the next may involve lab characterization of arm/fire sequences, or range support evaluating effect on target.

From interface control documentation and preliminary design reviews to Fuze Safety Review Board qualification, you’ll be the technical owner who turns rigorous safety requirements into fielded, mission-ready hardware.

You’ll work at the intersection of warfighter intent and technical execution, balancing rigor with agility, and compliance with tactical need. This career is for electrical engineers who treat safety as a discipline, sweat the details, and thrive in a fast-moving, multi-disciplinary environment.

• Serve as the technical owner for ESAD/ESAF integration across Firestorm munition payloads—leading electrical design, integration, test, and certification on sUAS platforms.
• Design firing-set electronics—including energy storage and management, charge/fire circuitry, and initiation interfaces for electric initiators.
• Architect arming and safety logic—including independent environmental sensing and arming features—to satisfy fuze design safety criteria and prevent inadvertent function.
• Develop schematic capture, PCB layout, and mixed-signal designs, addressing signal integrity, power integrity, and reliability across the full operating envelope.
• Define and document the electrical interfaces between the ESAD/ESAF, flight controller, payload bus, and host platform via Interface Control Documents (ICDs).
• Lead environmental, EMI/EMC, and HERO (Hazards of Electromagnetic Radiation to Ordnance) analysis and testing to ensure safe operation in the deployed electromagnetic environment.
• Plan and execute test campaigns across bench, environmental, ground, and flight environments—supporting test readiness reviews, arm/fire sequence characterization, and post-test data analysis.
• Ensure all safe-and-arm designs comply with applicable DoD fuze safety standards (e.g., MIL-STD-1316, MIL-STD-1901, STANAG 4187) and applicable airworthiness and export regulations (e.g., ITAR).
• Lead or support Fuze Safety Review Board (FSRB) qualification efforts, including safety assessments, hazard analyses, and qualification test documentation.
• Develop and present technical material at internal and external design reviews, customer meetings, and certification milestones.
• Coordinate with embedded software, mechanical, and payload teams—and with external partners on initiation…
