Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud platform, serving millions of customers ranging from startups to Fortune 500 enterprises. AWS operates a massive global infrastructure that powers everything from e‑commerce sites to AI‑driven applications. In India, Amazon has built several state‑of‑the‑art data centres that host critical workloads for customers across the sub‑continent. These facilities are the backbone of the cloud, and keeping them running 24x7 requires a blend of cutting‑edge engineering, rigorous operational discipline, and a culture of relentless improvement. The Data Centre Engineering Operations team is at the heart of this effort, ensuring that every piece of equipment – from power distribution units to cooling towers – functions flawlessly and meets the highest safety and efficiency standards. The role of Data Centre Engineering Operations Engineer is a hands‑on, senior‑level position that acts as the single point of accountability for the mechanical, electrical, and fire‑suppression systems across Amazon’s Indian data‑centre portfolio. You will own the end‑to‑end lifecycle of infrastructure changes, incidents, and preventive maintenance, while collaborating with cross‑functional teams such as construction, security, logistics, and vendor management. The position demands a deep technical background, strong problem‑solving abilities, and the willingness to work in a 24x7 on‑call environment with rotating shifts. You will be instrumental in driving standardisation, automation, and continuous improvement across all facilities. Key responsibilities include: 1. Lead the planning, execution, and documentation of all data‑centre changes, events, incidents, and problem‑resolution activities. 2. Oversee preventive and corrective maintenance of electrical systems (sub‑stations, UPS, generators, PDUs, ATS, battery banks) and mechanical systems (CRAC/CRAH, chillers, cooling towers, pumps, valves). 3. Manage asset and inventory records, ensuring accurate tracking of critical equipment. 4. Develop and maintain method statements, SOPs, emergency response procedures, and technical documentation, driving consistency across sites. 5. Produce regular engineering performance reports, monitoring SLA and KPI compliance for facilities. 6. Provide hands‑on support for rack installations, de‑commissioning, equipment upgrades, and internal audits. 7. Conduct technical compliance audits and ensure timely closure of corrective action plans. 8. Coordinate with landlords, vendors, construction teams, and internal stakeholders to align on project timelines and safety standards. 9. Lead incident communication, trend analysis, and post‑mortem reporting to senior management. 10. Mentor junior engineers and contribute to the automation of routine operational tasks using scripting or infrastructure‑as‑code tools. The technical stack for this role includes a deep understanding of power distribution (transformers, switchgear, VFI UPS, DRUPS), backup power (diesel/gas generators, fuel systems), battery management, surge suppression, and harmonic filtering. On the mechanical side, expertise in HVAC systems (CRAC/CRAH, AHU), chilled water plants, cooling towers, and associated piping and control systems is essential. Familiarity with SCADA, BMS, and monitoring platforms, as well as basic scripting (Python, PowerShell) for automation, will be advantageous. Career growth at AWS is highly merit‑based. Successful engineers can progress to senior engineering roles, lead large‑scale facility programmes, or transition into technical program management, reliability engineering, or data‑centre design leadership. The exposure to cutting‑edge infrastructure, global best practices, and a culture that rewards innovation makes this an attractive opportunity for ambitious engineers. Why join Amazon? Apart from the brand prestige, Amazon offers a fast‑paced environment where you can work on some of the most complex infrastructure challenges in the world. Employees benefit from competitive compensation, comprehensive health benefits, continuous learning programs, and a culture that encourages ownership and long‑term impact. The inclusive work culture, focus on safety, and commitment to sustainability further enhance the employee experience.
