About The Position

Firestorm is seeking a Senior Electrical Engineer to join its Munitions Group and own the electrical design, integration, testing, and certification of Electronic Safe-and-Arm Devices (ESAD) and Electronic Safe-Arm-and-Fire (ESAF) systems across tactical sUAS platforms. The role is responsible for firing electronics, energy storage and management, environmental sensing, and arming logic that keep weapons inert until they are intentionally armed and enable reliable operation on command. The engineer will translate safety requirements into fielded hardware, from initial design through deployment, while balancing technical rigor, compliance, and operational needs. The work spans schematic capture and PCB layout, lab characterization of arm/fire sequences, environmental and electromagnetic analysis, and support for range testing and effect-on-target evaluation. The role also owns electrical interface definition and documentation, design reviews, qualification activities, and coordination across embedded software, mechanical, payload, program, and external partner teams. The position is based at Firestorm's San Diego, California headquarters and requires up to 20% CONUS and OCONUS travel. PPE is provided, and compliance with safety protocols and environmental controls is mandatory; the role requires the ability to lift 30 pounds.

Requirements

Bachelor's degree in Electrical Engineering, Electrical & Computer Engineering, or a related STEM field, or equivalent engineering experience in lieu of a degree.
At least 7 years of electrical engineering experience, including at least 3 years directly supporting safe-and-arm, fuzing, or munitions firing electronics.
Hands-on experience designing firing-set or initiation electronics, including energy storage and management, charge/fire circuitry, and electric-initiator interfaces.
Working knowledge of fuze and weapon safety design criteria, including MIL-STD-1316 and related safe-and-arm standards.
Familiarity with environmental, EMI/EMC, and HERO considerations for ordnance electronics.
Strong communication, presentation, and interpersonal skills, including the ability to work across departments and act as a prime technical contact.
Customer-focused approach and ability to formulate and implement plans to resolve technical engineering problems.
U.S. citizenship and ability to obtain and maintain a U.S. Government security clearance.

Nice To Haves

Direct experience designing ESAD/ESAF systems for guided munitions, loitering munitions, or air-delivered weapons.
Experience taking a safe-and-arm device through Fuze Safety Review Board (FSRB) qualification.
Hands-on experience with electric initiation systems such as exploding bridgewire (EBW), exploding foil initiators (EFI), or hot-wire devices.
Working knowledge of MIL-STD-1901, MIL-STD-1911, STANAG 4187, and related fuze safety and interoperability standards.
Proficiency with schematic capture and PCB layout tools, mixed-signal design, and electrical bring-up and debug of prototype hardware.
Experience collaborating closely with embedded software/firmware teams on arming logic and built-in test.
Familiarity with Modular Open Systems Architecture (MOSA) and store/payload interface standards.
Experience working with DoD customers or within the defense acquisition environment.
Proficiency with Jira, Confluence, or similar project tracking tools.
Hands-on field experience supporting ground or flight testing of UAS platforms or weapon systems.
Experience working with military range authorities and supporting Explosive Safety Submissions (ESS).
Active DoD security clearance.

Responsibilities

Own ESAD/ESAF integration across 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 electric-initiator interfaces.
Architect arming and safety logic, including independent environmental sensing and arming features, to meet 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 operating envelope.
Define and document electrical interfaces among the ESAD/ESAF, flight controller, payload bus, and host platform through Interface Control Documents (ICDs).
Lead environmental, EMI/EMC, and HERO analysis and testing for safe operation in deployed electromagnetic environments.
Plan and execute bench, environmental, ground, and flight test campaigns; support test readiness reviews, arm/fire sequence characterization, and post-test data analysis.
Ensure safe-and-arm designs comply with applicable DoD fuze safety standards, airworthiness requirements, and export regulations.
Lead or support Fuze Safety Review Board (FSRB) qualification, 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 payloads teams and external partners on initiation systems, fuzing, and energetic materials to close the effector chain.
Collaborate with program managers to align technical execution with program objectives, schedules, and constraints.
Support proposals, white papers, and early-phase concept development for future safe-and-arm and fuzing capabilities.
