Sr. Mgr Liquid Cooling Ops, AWS Hardware Engineering Services

This is a founding leadership role. The Senior Manager, Liquid Cooling Operations will build and lead a new organization responsible for the health and integrity of cooling fluid flowing through AWS's server fleet. The team is being stood up from scratch, and the person who takes this role will define what the function looks like, hire the core engineers, establish the standards, and own the outcomes across three interconnected disciplines: fluid chemistry and health monitoring, leak detection and physical operations, and system performance analytics.

This role sits at the intersection of chemistry, detection engineering, and fleet-scale operations. The successful candidate will be someone who has operated critical fluid infrastructure at scale, understands corrosion and fluid degradation as engineering problems, and has the organizational range to resolve ambiguous ownership boundaries with adjacent teams while keeping their own team focused and productive.


Key job responsibilities
**Fluid Health and Chemistry.** Own coolant specification, qualification, and continuous fleet-wide monitoring. Lead material compatibility validation and make the formal recommendation on fluid chemistry. Monitor deployed fluid for corrosion, microbial growth, and chemical breakdown.

**Leak Detection and Operations.** Own the detection architecture end to end, from sensors through automated shutdown. Drive root cause forensics and feed findings back to hardware teams. Partner with datacetner team all physical fluid operations including commissioning, cleanliness standards, and the fluid-to-facility interface.

**System Performance and Analytics.** Correlate fluid health data with thermal performance, flow dynamics, and fleet-wide trends. Own digital twin models that predict replacement windows and inform design decisions.

Basic Qualifications

- Bachelor’s degree or higher in Chemistry, Chemical Engineering, Mechanical Engineering, Materials Science or equivalent.
- Experience fluid systems, corrosion science, or thermal management at scale
- Experience leading organizations of 20+ engineers across multiple disciplines (chemistry, controls/detection, physical operations, data/analytics) and managing managers
- Track record of standing up new organizations or capabilities from scratch, including hiring, authoring foundational specifications, and establishing operational standards
- Strong operational discipline with a bias toward measurement and data-driven decision-making
- Background in industries where fluid integrity is mission-critical — oil and gas, semiconductor fabrication, pharmaceutical fluid systems, or automotive

Preferred Qualifications

- Advanced degree in chemical engineering, materials science, mechanical engineering, fluid mechanics, or a related field
- 10+ years of engineering experience in fluid systems, corrosion management, thermal management, or a closely related discipline
- 5+ years of experience managing managers
- Proven ability to hire and develop talent from non-traditional engineering backgrounds
- Direct experience with leak detection systems, corrosion monitoring programs, or controlled-environment operations (cleanrooms, contained fluid systems)
- Familiarity with large-scale infrastructure environments (not required — candidates from outside data center backgrounds are encouraged to apply)
