Sr. Quality & Reliability Engineer, Hardware Engineering Services

About the role

AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. In other words, we’re the people who keep the cloud running. We support all AWS data centers and all of the servers, storage, networking, power, and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems, with thousands of variables impacting the supply chain — and we’re looking for talented people who want to help.

Responsibilities

• Define and execute reliability validation strategies for liquid cooling components and subsystems
• Develop test plans (e.g., HALT, stress testing, lifecycle validation) aligned to real-world use conditions
• Lead DFMEA and Design for Reliability (DFR) activities to identify and mitigate risks early
• Partner with system teams to ensure proper integration testing and margin validation
• Drive root cause analysis for component qualification and fleet failures
• Drive corrective and preventive actions with internal teams, manufacturing partners and component suppliers
• Translate failure mechanisms into actionable design, material, and process improvements
• Lead Supplier Quality
• Define critical-to-quality requirements and process controls for suppliers
• Conduct supplier audits and support qualification readiness
• Partner with suppliers to improve process capability, reliability performance, and defect detection
• Analyze fleet performance data (e.g., failure trends, AFR, ARR) for liquid cooling components
• Apply statistical methods (e.g., Weibull analysis) to predict risk and inform actions
• Drive systemic issue identification and resolution across platforms
• Influence Cross-Functional Decisions
• Communicate risks clearly
• Provide data-driven input to design and architecture tradeoffs

Qualifications

• Experience in developing functional specifications, design verification plans and functional test procedures
• 5+ years of root cause analysis and process design experience
• Knowledge of process improvement and quality measures
• Experience working across teams and influencing teams that are not your own
• Experience that includes strong analytical skills, attention to detail, and effective communication abilities
• Bachelor's degree in Reliability Engineering, Physics, Material Science, Mechanical engineering or related field
• 5+ years of Quality, Reliability, and/or mechanical design engineering work (experience with server platforms or data center operations preferred)
• Strong background in reliability engineering methods (DFMEA, ALT, statistical analysis) at the sub-assembly or component level

Preferred Qualifications

• Experience working with interdisciplinary teams to execute product design from concept to production
• Experience with the project management of technical projects
• Master's Degree or PhD in Reliability Engineering, Quality Engineering, or related field
• Demonstrated ability to uncover systemic issues prior to NPI
• Experience with liquid cooling technologies (e.g., cold plates, quick disconnects, fluid systems) strongly preferred
• Knowledge of fluid system failure modes (leakage, corrosion, clogging, material compatibility)
• Analytical, test plan, and test procedure development experience related to server platforms or high-tech hardware
• Demonstrated ability to drive failure analysis activities to root cause swiftly and accurately
• Able to work in a diverse team
• Experience operating in ambiguous environments where requirements are not fully defined, including establishing reliability strategies, test plans, and risk frameworks from first principles
• Reliability modeling and materials characterization experience
• Ability to influence development teams, procurement and external partners
• Experience working with global suppliers and ODM/OEM partners
