What You’ll Be Doing:

• Specify and qualify wetted metals & alloys (e.g., Cu/CuNi, Ni-braze, 316L/2205 SS, Ti, Al), polymers and composites (PPSU, PEEK, PVDF, PTFE), elastomers (EPDM, FKM/FFKM, NBR, HNBR), solders/brazes, sealants/adhesives, coatings/linings, and surface treatments (passivation, phosphating, anodizing).

• Define fluid compatibility envelopes for single-phase glycols/water and two-phase working fluids/refrigerants, includingoils/additives/biocides/inhibitors;write cleanliness, chemistry, and monitoring specs (e.g., pH, conductivity, chlorides, hardness, TOC, particle count).

• Architect corrosion and erosion control programs, including mitigation of galvanic couples between Al–Cu and other dissimilar metals, crevice and under-deposit corrosion, MIC, and slurry erosion; establish flow velocity and operational limits to prevent erosive wear in all fluid systems.

• Lead test and qualification plans: coupon and assembly-level testing (ASTM/ISO/G-series), electrochemical methods (EIS, potentiodynamic), elastomer swell/durometer retention, pressure/thermal cycling, HALT/HASS, cleanliness verification (ISO 4406/MIL-STD-1246C), life modeling & acceleration factors.

• Run failure analyses and close the loop with design and suppliers: root-cause via SEM/EDS, XRD, XPS, FTIR, GC-MS, ICP-OES/MS, ion chromatography; drive corrective actions (8D/FRACAS) and update specifications.

• Write and enforce material and process specifications for partners (AEC/MEP, OEMs, CMs, vendors); review P&IDs, BoMs, weld maps, braze/filler selections, flange/gasket stacks, passivation & flushing procedures, preservation & layup plans.

• Integrate materials intelligence into digital twins: providetemperature-/chemistry-dependentproperty libraries anddegradation modelsfor SimReady assets (used in hydronic/thermal/CFD and reliability simulations).

• Engage with industry standards bodies such as ASHRAE, ASME, and the Open Compute Project (OCP) to advance industry standards, testing methodologies, and materials best practices for liquid-cooled data centers.

• Ensure regulatory and sustainability alignment: guide compliance for RoHS/REACH/TSCA, potable/non-potable water use, refrigerant transitions, PFAS minimization strategies, and end-of-life considerations.

• Partner across NVIDIA (DCE, product cooling, reliability, controls) and with external vendors to ensure designs are manufacturable, serviceable, and scalable at GW scope.

What we need to see:

• BS/MS (or equivalent experience) in Materials Science/Engineering, Metallurgy, Chemical Engineering, or related field; PhD a plus

• 12+ years in materials for mission-critical infrastructure (data centers, power, process, aerospace, or semiconductor fabs) with emphasis on wetted systems.

• Hands-on expertise in corrosion science, fluid–material compatibility, and elastomer/polymer selection for mixed-metal hydronic and refrigeration systems.

• Proven experience crafting material and cleanliness specifications, test plans, and supplier qualification packages; strong command of ASTM/ISO test methods.

• Ability to analyze and mitigate galvanic corrosion between dissimilar materials, with knowledge of coatings, isolation methods, and material pair optimization.

• Experience defining fluid flow and erosion limits to maintain material integrity and long-term reliability.

• Proficiency with materials characterization and FA (SEM/EDS, XRD, XPS, ICP-OES/MS, FTIR/GC-MS) and interpretation into actionable design rules.

• Ability to translate lab results into field-relevant life models and operating guard-bands (chemistry, temperature, velocity, ΔP, vibration).

• Clear, concise technical communication; effective collaboration with design, manufacturing, and vendor teams.

Ways to stand out from the crowd:

• Experience with AI/HPC and data center cooling systems (CRAHs, CDUs, HXs, manifolds, plants, towers, dry coolers) and knowledge of two-phase fluids, refrigerants, and seal/oil compatibility.

• Knowledge of MEP codes, ASME/PED standards, welding/brazing, NDE, and water-treatment programs for reliable, long-life operation.

• Experience linking materials data to digital twins and CFD/hydronic models, collaborating with suppliers and standards bodies (ASHRAE, ASME, OCP, ASTM).

• Demonstrated engagement with standards bodies (ASHRAE TC9.9,ASME, OCP, ASTM) and contribution to new test or specificationdevelopment.

• Track record driving multi-supplier alignment, cost-reliabilitytradeoffs, and sustainability targets (heat reuse, low-toxicity
