Senior Design Engineer, Solid Rocket Motor Ignition Systems

## The future of aerospace and defense starts here. Ursa Major was founded to revolutionize how America and its allies access and apply high-performance propulsion, from hypersonics to solid rocket motors, satellite maneuvering and launch. We design and deliver propulsion and defense systems that solve the most urgent and critical national security demands.

We are seeking a highly skilled and motivated Ordnance Engineer to join our propulsion engineering team. In this role, you will lead and support the design, development, qualification, and procurement of ordnance systems and components for advanced Solid Rocket Motor (SRM) applications.

You will serve as the technical subject matter expert (SME) for ordnance components throughout the entire product lifecycle - from initial concept definition through flight qualification and production support.

The ideal candidate will have deep technical expertise in initiators, ignition systems, safe-and-arm devices, flight/thrust termination systems, and stage separation mechanisms. ## Primary Responsibilities - Component Design & Development: Lead the engineering lifecycle of energetic ordnance components, including electro-explosive devices (EEDs), igniters, electronic and mechanical safe-and-arm devices (SADs/ESADs, EISDs), exploding foil devices (LEEFIs) and exploding bridgewire (EBW) systems. - Separation & Termination Systems: Design, analyze, and integrate ordnance subcomponents, including Linear Shaped Charges (LSC) for flight termination (FTS) or thrust termination, as well as exploding bolts, frangible nuts, and pin pullers for stage separation. - Subcontractor & Procurement Technical Management: Author technical procurement specifications, Statements of Work (SOW), and Interface Control Documents (ICDs).

Serve as the primary technical interface to ordnance sub-tier suppliers, ensuring compliance with rigorous aerospace standards. - Testing & Qualification: Author test plans, procedures, and reports for component-level and system-level ordnance testing.

Oversee environmental testing (vibration, shock, thermal vacuum) and energetic firing tests. - Failure Investigation & Risk Analysis: Lead Root Cause and Corrective Action (RCCA) investigations for ordnance manufacturing anomalies or test failures.

Perform Failure Modes, Effects, and Criticality Analysis (FMECA). - Cross-Functional Collaboration: Partner with Systems Engineering, Integration & Test, Safety, Quality Assurance, and programmatic teams to ensure seamless system integration and safety compliance. ## Basic Qualifications - Education: Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Chemical Engineering, or a related STEM discipline. - Experience: Minimum of 5+ years of direct experience in aerospace ordnance, energetic materials, or rocket motor ignition systems (Level/Title can be adjusted based on experience). - Technical Standards: Working knowledge of industry standards such as MIL-STD-1901 , MIL-STD-1576 , MIL-DTL-23659 , and RCC 319 (Range Safety User Requirements). - Security: Must be a U.S.

Citizen with the ability to obtain and maintain a Department of Defense (DoD) Secret Security Clearance. ## Preferred Qualifications - Active DoD Secret or Top Secret Clearance. - Experience with both hot-gas ignition systems and pyrotechnic ignition strings for large-scale solid rocket motors. - Strong familiarity with High-Voltage Detonators (EBW/EFI) - Experience presenting at formal design reviews (CoDR, PDR, CDR) to internal leadership and military customers (e.g., MDA, US Navy, US Air Force, US Space Force, etc).
