Lead Engineer – Aero Engine Power & Thermal Management Systems; PTMS

Role Summary

The Senior / Lead PTMS Engineer is responsible for the architecture, analysis, optimization, and integration of aero engine power and thermal management systems
. This role serves as a technical focal for engine-level PTMS, leading system trade studies, requirements definition, and verification activities while working closely with OEM and airframers, Integrated Product Teams (IPTs), CDS Accessories, and industrial partners to deliver compliant, robust, and producible PTMS solutions.

System Modeling, Analysis & Optimization

• Develop and maintain engine PTMS system models capturing electrical, thermal, pneumatic, and mechanical domains.
• Define and manage heat transfer allocations for Functional sizing, Duty cycle definition
• Utilize PTMS Control design and optimization environments to support collaborative system development.
• Utilize PTMS-PSA engine system trade study environments to assess performance, operability, and integration impacts.
• Lead integration and performance assessment of engine heat management subsystems
  , including ACCA / ICCA / buffer architectures, Customer, start, inlet, and fan bleeds, Anti-ice systems, Engine and aircraft heat exchangers
• Manage engine-to-airframe PTMS integration
  , ensuring compliance with Aircraft power requirements and Heat rejection requirements
• Ensure solutions meet packaging, weight, maintainability, and physical integration constraints through collaborative design with airframer and internal IPTs.
• Share responsibility with CDS Accessories for fuel system integration, specifically for engine-control-related fuel system aspects.
• Support engine PTMS functional and physical requirements
  , including allocation, traceability, and change management.
• Manage requirement verification and validation (V&V) activities in coordination with airframers and internal certification teams.
• Support compliance and certification through discipline reviews, documentation, and design reviews.
• Mentor engineers and support PTMS capability and process development within the organization.
