Operations and Delivery Engineering Lead, Critical Facilities

ABOUT FLUIDSTACK We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it. We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI. We hire people who care deeply about this problem space. If that is you, please apply! ABOUT THE ROLE We are seeking an experienced Operations and Delivery Engineering Lead to own the engineering scope of our data centers across their full life cycle — from sites under construction, through turnover, to all subsequent engineering work performed on live infrastructure. This is a senior, people-management role spanning mechanical/cooling, electrical/power, controls/BMS, and fire/life safety. You will lead a multi-disciplinary team of engineers who own technical support of sites under construction, support the commissioning effort through turnover, and act as the engineering owner for any work performed on the building once it is live — additions, modifications, retrofits, controls changes, capacity moves, and incident-driven fixes. The construction-phase presence is deliberate: in partnership with Design Engineering, the team builds a thorough, first-hand understanding of how each building is put together and how it is intended to operate, so that by the time it goes live the engineers who will own its life cycle already know it inside and out. You chair the site Change Control Board (CCB), where you approve technical changes to data center systems and the way they operate. You do not run day-to-day operations — that sits with the Critical Facilities Operations team — and you do not own design or commissioning — those sit with Design Engineering and the Commissioning Agent — but you set the engineering bar both functions execute against and serve as the engineering escalation point when something on site doesn’t behave the way it was designed to. You partner closely with Design Engineering, Construction, Commissioning Agents, Critical Facilities Operations, Capacity Planning, and equipment vendors. You are equally comfortable walking a job site with a GC, red-lining a one-line diagram, reviewing a Sequence of Operations, chairing a CCB, and standing up an engineering bridge during a complex incident. This role requires approximately 50% travel to live job sites and data centers. RESPONSIBILITIES Team Leadership & People Management - Lead, coach, and develop a multi-disciplinary team of delivery and lifecycle engineers; own hiring, onboarding, performance management, career development, and retention. - Set the technical bar across disciplines and ensure each engineer has clear ownership across the projects, buildings, and systems in their portfolio. - Plan and prioritize the team’s workload across construction support, commissioning support, lifecycle engineering work on live infrastructure, and engineering escalations from Operations. - Build and maintain an on-call rotation that provides qualified engineering support to Operations and to active construction sites when issues exceed the operating team’s authority. - Foster a strong safety culture and a blameless, learning-oriented approach to incidents, near-misses, and commissioning findings. Construction & Delivery Engineering - Own technical support of sites under construction in partnership with Design Engineering; embed engineers as the on-site technical resource across mechanical, electrical, controls, and fire/life safety scopes. - Use the construction phase to develop a deep, first-hand understanding of how each building is constructed and how it is intended to operate, so that the engineers who will own its life cycle are fully fluent in the asset before it goes live. - Represent the Operations and Delivery Engineering team in design reviews, constructability reviews, submittal reviews, and RFI/change-order decisions; flag deviations from design intent and route them back to Design Engineering for resolution. - Provide technical support to the Commissioning Agent and Design Engineering through FAT, SAT, and Levels 1–5 commissioning, including review of functional test scripts and witness participation where useful, without assuming ownership of the commissioning program. - Lead the operational readiness and turnover process: ensure new systems are fully documented, alarmed, integrated into BMS/EPMS/DCIM, trained on, and supportable before they carry critical load. - Hold GCs, subcontractors, and vendors to the site’s safety, quality, and documentation standards through energization and turnover. Lifecycle Engineering on Live Infrastructure - Own the engineering scope for any work performed on live data center infrastructure, regardless of size or type — capacity additions, equipment replacements, controls and BMS/EPMS changes, electrical or mechanical configuration changes, retrofits, and incident-driven remediation. - Scope, design, and project-manage lifecycle work in partnership with Design Engineering and Operations, from concept through execution and back-to-service. - Maintain a forward-looking view of site risk, single points of failure, and system interdependencies, and convert that view into a prioritized lifecycle and reliability roadmap. - Provide engineering input to capacity and load reviews so additions and changes stay within the safe operating envelope
