Job description

Responsibilities

Vehicular System Design and Development

• Lead the definition, design, and validation of vehicle-level systems, encompassing conventional and hybrid-electric drive architectures.
• Translate customer and mission requirements into clear system and subsystem specifications, ensuring performance, reliability, and safety targets are met.
• Conduct competitive benchmarking and trade-off analysis to guide platform design evolution and technology selection.
• Establish and maintain configuration baselines across multiple vehicle variants, ensuring design integrity and full traceability throughout the product lifecycle.
• Drive system integration of new technologies, such as digital architectures, power management systems, and advanced driveline solutions (HED, BEV) into existing vehicle platforms.

Implementation and Integration

• Oversee end-to-end implementation and integration activities, coordinating with multidisciplinary internal teams and key external partners or OEM suppliers.
• Develop and execute validation and verification (V&V) plans, including bench tests, subsystem integration, and vehicle-level trials.
• Lead root-cause investigations and implement robust corrective actions to address system issues, ensuring continuous system reliability improvement.

Documentation, Governance, and Compliance

• Review engineering documentation, including System Requirement Specifications, Interface Control Documents, and Design Validation Plans.
• Ensure strict adherence to automotive and defence standards (ISO 26262, ISO 9001, MIL-STD, GVA, J1939) and regulatory compliance.
• Oversee configuration control, BOM accuracy, drawings, and part numbering discipline through PLM systems, maintaining consistency across project baselines.

Continuous Improvement and Innovation

• Identify and drive system level optimisation initiatives to enhance performance, reduce cost, and simplify maintenance.
• Lead technical studies and R&D investigations on emerging automotive and defence technologies, such as electrification, digital architecture, and modular system design.
• Mentor junior engineers in system design methodologies and configuration management practices.

Cross-Functional Collaboration and Technical Leadership

• Collaborate closely with mechanical, electrical, software, and manufacturing engineering teams to deliver fully integrated and validated vehicle solutions.
• Serve as a technical focal point in cross-functional project teams, aligning engineering decisions with business strategy, cost, and delivery objectives.
• Engage with project managers, product leads, and customers to ensure engineering deliverables meet contractual and performance commitments.

Requirements

• Bachelor’s in Mechanical, Automotive, Electrical, or Systems Engineering.
• 8–10 years of experience in automotive system design, integration, or platform development—preferably within defence, heavy-duty or off-road vehicles.
• Strong technical expertise in vehicle architectures, hybrid-electric systems, and subsystem integration (powertrain, driveline, suspension, braking, electrical).
• Proficiency in system engineering tools (e.g., MATLAB/Simulink, Teamcenter, or equivalent tools).
• Demonstrated experience in configuration management, engineering change control, and lifecycle documentation.
• Proven analytical, problem-solving, and decision-making capabilities with a structured, data-driven approach.
• Excellent communication and stakeholder management skills, able to represent engineering priorities at programme and customer reviews.
• Experience mentoring or leading small engineering teams and contributing to capability development
