About The Position

Firestorm Labs is seeking an experienced Firmware Engineer specializing in embedded platforms to support the development, integration, and deployment of avionics and embedded systems for next-generation unmanned aerial systems (UAS). The role advances flight-critical firmware and avionics systems to meet performance and reliability standards and enable mission readiness. The engineer will work with cross-functional teams to integrate flight-critical systems, resolve complex technical issues across domains, and support independent research and development (IRAD) and field operations. The work is hands-on and detail-oriented in a fast-paced environment where rapid iteration and field validation are central. The role is based at Firestorm’s San Diego, California headquarters and requires on-site presence. It typically operates in an office and manufacturing environment, with possible exposure to loud noise, heat, cold, dust, or chemicals while using appropriate PPE. Travel of up to 15% domestically is required for field operations, integration events, customer support, and testing. Relocation assistance may be included in an offer where appropriate. The U.S. salary range is $132,000–$178,000, with actual compensation dependent on factors such as experience, education, skills, location, and business needs.
