You will lead the electrical design, manufacturing validation and commissioning of modular data center (MDC) infrastructure for hyperscale customers - translating evolving high density AI compute requirements into practical power architectures from 33 kV utility intake through to liquid cooled GPU rack busway. You will act as an Electrical SME across multi-disciplinary teams, OEM suppliers and global project sites, with a bias for execution and a track record of delivering complex multi-MW builds on schedule. What you'll do: * Lead end-to-end electrical design of modular data center power systems: MV/LV distribution (11-22 kV transformers, 480V/415V switchboards), UPS systems (2N/2(N+1)), and diesel generator parealleling for multi-MW AI compute loads. * Define and specify rack and row level power distribution including busbar systems (48V/400V/800V DC or low voltage AC), current ratings, clearances, creepage, short-circuit withstand, thermal units, and insulation requirements. * Act as Electrical SME on modular skid and E-house design; produce one-line and three-line diagrams, point-to-point schematics, harnessing drawings and full BOM for all electrical systems. * Size, select and support procurement of switchgear, UPS, transformers, MCCs, VFDs, PDUs, busway, RPPs, conductors, conduit, and control systems; evaluate DFM/cost trade-offs with suppliers. * Collaborate with mechanical and thermal teams to ensure electrical layouts are compatible with high-density liquid cooling architecture (CDUs, manifolds, cold plates), including cable/busbar proximity to high-heat and high-flow components. * Model load flows, fault levels, protection coordination, arc flash hazard, and grid transient compliance using ETAP, SKM, or equivalent; apply Uptime Institute Tier III/IV methodology to availability calculations. * Define and validate protection and selectivity strategy (breakers, fuses, protective relays) across the full distribution chain; specify telemetry and controls requirements including metering, waveform capture, breaker/relay status, UPS and battery health, and CDU/coolant alarms. * Drive compliance with NEC/NFPA 70, NFPA 70E, IEC 60364/61439, UL, IEEE, and OCP/ORV3 standards; manage AHJ submissions and support permit processes. * Lead vendor qualification for busbar, switchgear, UPS, and rack power OEMs; review shop drawings, ITP documents, and FAT/SAT procedures; witness first-of-kind quality inspections at vendor facilities. * Author integrated systems test (IST) and commissioning plans; lead HV/LV energization witnessing; support burn-in, reliability, and interoperability testing for rack deployments. * Conduct DFMEA/FMEA and design reviews covering failure modes such as loose connections, hot spots, arcing, and coolant-leak interaction; lead risk assessments and corrective action tracking. * Generate and maintain design documentation: specifications, interface control documents (ICDs), test plans, as-built drawings, O&M procedures, spare parts registers, and IOM manuals. * Provide technical input to sales and proposal teams on bid tabs, cost estimates, and customer-facing specifications; represent Submer in technical discussions with hyperscale customers and OEM partners. * Drive continuous improvement of MDC reference designs; contribute to PUE/WUE optimisation and energy efficiency targets. ## Related Videos - [WebAssembly Revolution: Elevating JavaScript's Reach and Performance](https://www.wearedevelopers.com/videos/1149-webassembly-revolution-elevating-javascript-s-reach-and-performance) - [DevOps at Netflix](https://www.wearedevelopers.com/videos/270-devops-at-netflix) - [What makes Cybersecurity different for critical infrastructure?](https://www.wearedevelopers.com/videos/571-what-makes-cybersecurity-different-for-critical-infrastructure) - [Leading with Reliability: Applying SRE Principles to Build Stronger Engineering Organizations](https://www.wearedevelopers.com/videos/100185-leading-with-reliability-applying-sre-principles-to-build-stronger-engineering-organizations) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Resilient by Design: Building Robust Architectures in High-Stakes Financial Systems](https://www.wearedevelopers.com/videos/2106-resilient-by-design-building-robust-architectures-in-high-stakes-financial-systems) ## Related Articles - [A Guide to Green Tech and Green IT Careers](https://www.wearedevelopers.com/magazine/374-a-guide-to-green-tech-and-green-it-careers) - [Top 6 Hackathons for Developers in 2023](https://www.wearedevelopers.com/magazine/263-top-6-hackathons-for-developers-in-2023) - [6 Emerging Technologies We’ll Learn About in 2025](https://www.wearedevelopers.com/magazine/381-6-emerging-technologies-we-ll-learn-about-in-2025) - [Best US AI Conferences for CTOs in 2026: Build vs. Buy, Vendor Evaluation, and Peer Intelligence](https://www.wearedevelopers.com/magazine/736-best-us-ai-conferences-for-ctos-in-2026-build-vs-buy-vendor-evaluation-and-peer-intelligence) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
