About the role

Key responsibilities & impact

Provide expert judgment and analysis for the design, development, and implementation of refrigerant heat exchangers and related technologies.
Act as technical owner / SME for condensers, evaporators, IRDs, and desiccant technologies across vehicle programs.
Develop the strategic vision for these components as integral parts of their sub-systems and drive the strategy application forward.
Lead innovation projects to support strategic vision.
Manage and approve engineering solutions from suppliers for heat exchanger core designs, manifolds, headers, integrated receiver driers, desiccant packaging, and interfaces.
Support and/or lead Product Development Teams (PDTs) as necessary to ensure component designs are properly coordinated with vehicle packaging, airflow, thermal systems, and manufacturing constraints.
Work with VPOs to decompose vehicle level performance requirements to the subsystem and component level.
Drive virtual analysis with internal teams and external suppliers to ensure performance.
Own and manage component cost, mass, performance, and quality strategy to have the best in industry TEC.
Manage component timing plan templates, ensuring alignment with program milestones, sourcing events, and validation deliverables.
Develop and maintain Interface Control Documents (ICDs) and KCDS for components.
Author and release component spec C2 for sourcing Statement of Requirements (SOR).
Participate in and lead technical reviews, peer reviews, and sourcing support activities, including supplier technical evaluations.
Conduct quality reviews and lead DFMEAs for components and linking with system-level FMEAs.
Drive design issue resolution using the Problem Resolution Tracking System (PRTS).
Lead and support benchmarking activities for current and emerging heat exchanger technologies (materials, architectures, manufacturing methods) to ensure the component strategy meets customer expectations with the lowest TEC.
Track, analyze, resolve and read across warranty and field issues, including root cause analysis and corrective action implementation.
Document and read across lessons learned into the appropriate document (Best Practice, K-PAC, GMW, etc).
Technically support DREs for assigned architectures, ensuring adherence to engineering best practices, peer review standards, and documentation requirements.
Support special projects (EWS, TierN etc) and advanced technology initiatives under ETL guidance.
Lead and influence others, often directing technical work without direct authority.
Exhibit a high degree of creativity, autonomy, and technical depth.
