Data Center Controls Technician, US-West, PHX

As a member of the Global Controls Team, you will collaborate with highly motivated operators, engineers and technicians in the data center industry to maintain and optimize critical infrastructure systems. You will be responsible for troubleshooting and maintaining the Building Management System (BMS) and Electrical Power Monitoring System (EPMS) while developing new processes and standards that drive innovation in the controls space.

AWS data centers utilize sophisticated industrial control systems to automatically operate mechanical equipment, maintaining optimal temperature and pressure conditions throughout the facilities. These systems integrate and monitor multiple critical components, including generators, uninterruptible power sources, diesel generators, electrical switchgear, power distribution units, variable frequency drives, automatic and static transfer switches, air-cooled and water-cooled chillers, pumps, cooling towers, heat exchangers, Computer Room Air Handlers (CRAHs), and air economizers. Within this industrial control system infrastructure, the BMS serves as the primary control platform for all mechanical systems within the data center, while the EPMS functions as the primary monitoring platform for all electrical systems. This position offers the opportunity to work with cutting-edge technology in mission-critical environments while contributing to the reliability and efficiency of AWS"s global infrastructure.

Key job responsibilities

Manage small to medium-sized projects and programs.

Perform point-to-point checkouts, first-line diagnostics, troubleshooting, and maintenance of BMS/EPMS code and hardware.

Provision servers, controllers, industrial PCs, and networks; test communication with third-party devices.

Install, replace, configure, and calibrate sensors.

Read and interpret electrical schematics and control panel drawings, applying closed-loop controls and field sensor scaling.

Supervise low-voltage contractors per AWS requirements.

Provide commissioning and systems-level testing; create red-lined drawings and documentation.

Follow change management processes for work requests and methods of procedures.

Participate in factory witness tests and perform root cause analysis during testing and commissioning.

Monitor ticketing systems, prioritize tasks, and manage service agreements (vendor scheduling, QA, invoice review).

Enforce on-site safety methodology.

Physical Requirements Lift and move up to 50 lbs; use ladders, platforms, and OSHA-standard PPE including safety harnesses.

A day in the life

As a Data Center Controls Technician, your primary customers are Data Center Engineering Operations (DCEO), who rely on you to keep Building Management Systems (BMS) and Electrical Power Monitoring Systems (EPMS) healthy and operational. On a given day, you are the boots on the ground solving problems that directly impact data center availability. You might diagnose a controller communication loss, calibrate instruments feeding inaccurate data to operators, or supervise vendors performing quarterly maintenance. For new builds, you perform point to point testing and support commissioning alongside construction teams.
