The Role
Technical Specialist - Heat Exchangers (Condensers, Evaporators, IRD & Desiccant)
The Technical Specialist is recognized as a subject matter expert (SME) with extensive experience in the design, specification, validation, and manufacturing of heat exchangers. A strong understanding of heat
transfer, fluid dynamics, materials, joining methods, and high-volume automotive manufacturing processes is required. Knowledge of refrigerant behavior, oil migration, and system-level HVAC / heat pump operation is expected.
This role includes global requirement development and strategy rollout, supporting execution and evaluation of BOM management, design, analysis, testing, validation, cost, quality, and durability of refrigerant heat exchanger components. Creativity, initiative, and a high level of independent technical judgment are required. The TS consults with the ETL, DREs, systems engineers, and cross-functional partners as needed and plays a key role in quality, reliability, durability, and warranty resolution activities. Support and regular travel to Lockport production facility is required.
What You'll Do
As a fully qualified individual contributor you will 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, developing the strategic vision for these components as integral parts of their sub-systems and driving 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 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.
This role requires the ability to lead and influence others, often directing technical work without direct authority. A high degree of creativity, autonomy, and technical depth is expected.
Your Skills & Abilities
Extensive experience in automotive refrigerant heat exchanger development, sourcing, validation, and production launch.
Demonstrated technical expertise in condenser, evaporator, IRD, and desiccant design, including system integration considerations.
Strong understanding of:
Heat transfer and thermodynamics
Refrigerant flow distribution and oil management
Airflow and pressure drop tradeoffs
Materials selection and corrosion durability
Experience managing suppliers on technical deliverables, including design, analysis, validation, and manufacturing readiness.
Demonstrated skill in supplier technical management and purchasing strategy support
Experience developing and executing RASICs for cross-functional engineering deliverables (CAE, Dimensional Engineering & GD&T, Manufacturing Bill of Process, CAD/PLM, Engineering Release/ECR).
Experience with component and system-level testing, including thermal performance, pressure cycling, vibration, environmental durability, and vehicle integration testing.
Strong oral and written communication skills, with the ability to communicate complex technical topics clearly to diverse audiences.
High level of analytical ability to solve unusual and complex engineering problems.
Understanding of DFSS methodologies; Black Belt / Red X knowledge preferred.
Ability to work effectively with cross-functional partners to meet shared objectives.
Strong demonstration of innovation and owning the outcome.
Demonstration of Artificial Intelligence tool usage applied to productivity enhancement (ex: analysis of CAE results, customer complaints, etc.)
What Will Give You a Competitive Edge
Deep technical experience in heat exchanger manufacturing processes, such as:
Aluminum brazing (CAB, vacuum brazing)
Tube/fin and microchannel architectures
Header and manifold joining methods
Desiccant integration and sealing strategies
Experience with HVAC and automotive heat pump systems for ICE and BEV applications.
Demonstrated expertise in heat exchanger integration with vehicle airflow, packaging
constraints, and assembly manufacturing requirements.
Experience developing service and UPC/FNA BOM strategies.
Familiarity with PE diagrams, refrigerants, and system-level thermal architectures.
Master's degree in Science or Engineering.
