Chief Engineer, Hypersonic Missile and Interceptor

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.

Ursa Major is seeking a Chief Engineer, Hypersonic Missile & Interceptor to serve as the technical authority and architectural owner for the Draper Engine Hypersonic program. This individual will be accountable for the end-to-end vehicle technical baseline, ensuring the successful integration of propulsion, structures, avionics, GNC, thermal, and mission systems into a flight-worthy, scalable vehicle solution.

As Chief Engineer, you will provide technical leadership across the full lifecycle—from requirements definition and trade studies through design, integration, test, and flight operations—while partnering closely with Program Management, Manufacturing, Mission Assurance, and Business Development. This role is critical to delivering reliable, high-performance systems to government and commercial customers on aggressive schedules.

Technical Authority & Architecture

• Own and maintain the vehicle system architecture, technical baseline, and configuration for the Draper Engine Vehicle.

• Serve as the final technical decision authority for vehicle-level design trades, requirements allocation, and risk acceptance.

• Ensure propulsion (Draper engine) is fully integrated into the vehicle system with appropriate margins, interfaces, and operational envelopes.

Systems Engineering & Integration

• Lead vehicle-level systems engineering, including requirements flow-down, interface control, verification & validation (V&V), and configuration management.

• Oversee cross-disciplinary integration across:

• Propulsion

• Structures & airframe

• GNC

• Avionics & software

• Thermal & TPS

• Mission & flight systems

• Chair technical reviews including SRR, PDR, CDR, TRR, and FRR.

Program Execution Support

• Partner with Program Management to balance performance, cost, schedule, and risk.

• Support proposal efforts, customer technical interchange meetings (TIMs), and design reviews with government and commercial customers.

• Identify technical risks early and lead mitigation plans through test, analysis, or design iteration.

Test, Qualification & Flight Readiness

• Define and approve vehicle-level test strategies including ground testing, qualification, and flight test.

• Ensure data-driven decisions using analysis, modeling, and test results.

• Provide technical sign-off for vehicle readiness and flight authorization.

Team Leadership & Mentorship

• Provide technical leadership and mentorship to subsystem leads and senior engineers.

• Foster a culture of engineering rigor, accountability, and rapid execution.

• Help scale engineering processes and standards as programs mature.

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or related field (Master’s or PhD strongly preferred).

• 12+ years of experience in aerospace vehicle development, including system-level ownership.

• Prior experience serving as a Chief Engineer, Lead Systems Engineer, or Vehicle Architect on a flight
