Principal Engineer, Solid Rocket Motor

About the role

EDGE is looking for a Principal Engineer for Solid Rocket Motors (SRM) to lead the design, development, testing, qualification and optimisation of next-generation missile propulsion systems. This is a critical technical authority role that guides multidisciplinary engineering teams through the complete SRM lifecycle, combining deep expertise in solid rocket motor design, internal ballistics and propulsion simulation with the ability to mentor engineers and deliver mission-critical programmes.

Key responsibilities

• Lead the design, development, optimisation and performance assessment of SRM propulsion systems.
• Provide technical authority for rocket motor architecture, safety analysis and subsystem integration.
• Review and approve rocket motor designs, ensuring performance, manufacturability, reliability and safety requirements are met.
• Plan and run CFD simulations and internal ballistic analyses to validate propulsion performance.
• Lead investigations into design anomalies and resolve discrepancies between analytical predictions and test results.
• Develop best practices, methodologies and standards for SRM design, modelling and simulation.
• Drive R&D on next-generation propulsion technologies and advanced manufacturing methods.
• Support missile system integration and review technical reports, design reviews, test reports and programme recommendations.
• Mentor propulsion engineers and ensure lessons learned and engineering knowledge are documented.

Required profile

• Bachelor's degree in Aerospace, Mechanical or Chemical Engineering, or a related discipline.
• 10-15 years of experience in SRM design, development, analysis or missile propulsion engineering.
• Demonstrated technical leadership in complex defence, aerospace, missile or space propulsion programmes.
• Proven experience supporting propulsion development through design, testing, qualification and production transition.
• Preferred: led a complete SRM development and qualification programme, and previous experience as Chief Engineer, Lead Engineer or Technical Authority.
• English proficiency required.

Required skills

• Solid rocket motor design and analysis, internal ballistics modelling and CFD simulation.
• Propellant chemistry, energetic materials and rocket motor safety assessment.
• Static test planning, qualification and verification activities, root cause analysis and technical reviews.
• Leadership competencies: mentoring, stakeholder engagement and cross-functional team leadership.

What we offer

• Competitive, tax-free salaries.
• Benefits that may include family visas, annual flight tickets, medical insurance for dependents and education allowances for children.
• A learning academy and digital learning platforms, plus career support.
