Position Overview:
We are seeking a Senior Systems Engineer – Electrical to own the detailed design validation, analysis, and optimization of Fleet’s data center power distribution topology from utility through the rack. This role requires a deep understanding of Fleet data center power topology, including breakers, PDUs, UPS systems, generators, busways, tap boxes, R-boxes, and whips, and how these elements behave across normal, maintenance, and failure scenarios.
The ideal candidate combines strong electrical engineering fundamentals with practical data center experience, ensuring rack-level power requirements are met, specifications and counts for power components are correct, and failover behaviors are well understood. This role is accountable for end-to-end electrical system integrity, including feed-down simulations, outage analysis, and upgrade impact assessments to optimize uptime SLAs and minimize power stranding.
Key Responsibilities:
Power Topology Ownership & Rack-Level Alignment:
- Develop and maintain a deep understanding of Fleet data center power topology, from utility through medium-voltage and low-voltage distribution, busways, tap boxes, R-boxes, and rack whips, down to rack power supplies and power shelves
- Ensure that tap box and R-box ratings meet rack power requirements, including continuous, peak, and redundancy constraints (e.g., N, N+1, 2N)
- Review and validate rack SKUs and associated power supply or power shelf specifications, ensuring compatibility with upstream distribution (feed counts, breaker ratings, connector types, redundancy configurations)
- Partner with rack engineering, capacity planners, and operations to ensure that rack layouts and deployment plans are electrically feasible within Fleet’s standard power lineups and site-specific constraints
Configuration, Specification, and Data Accuracy:
- Define, review, and maintain R-box specifications and counts, tap box specifications and counts, and whip specifications and counts for each deployment
- Ensure that all specifications and quantities are accurate, documented, and transmitted to capacity planners and procurement teams in a timely manner so they can plan, model, and procure required infrastructure
- Create and maintain standardized BOM templates and configuration libraries for electrical distribution components (busways, tap boxes, R-boxes, whips, breakers, PDUs, etc.) tied to specific rack SKUs and power tiers
- Collaborate with DCIM and tooling teams to ensure electrical topology, ratings, and connectivity are modeled with high fidelity and kept current
Electrical Failover & Outage Analysis:
- Perform electrical failover analysis across the power chain to ensure that credible outage scenarios (utility loss, generator failure, UPS failure, breaker trips, busway/tap/R-box faults, rack-level faults) do not lead to cascading failures
- Analyze breaker coordination, protective device settings, and selective tripping behavior to confirm faults are isolated without compromising redundant paths
- Model and validate how breakers, PDUs, UPS systems, generators, busways, tap boxes, R-boxes, and whips behave under fault, overload, and transfer conditions, and identify design or configuration changes to reduce operational risk
- Work closely with Site Operations and Facilities Engineering to incorporate lessons learned from real incidents into design standards, operating procedures, and protection settings
Feed-Down Simulation & System-Level Optimization:
- Simulate feed-down scenarios (e.g., loss of a feed, maintenance bypass, partial generator availability, UPS module failures) to understand upstream and downstream effects on the entire power lineup
- Use these simulations and scenario analyses to keep failure and maintenance events within uptime SLAs
- Minimize power stranding by balancing capacity across feeds, phases, and power paths while preserving redundancy
- Identify structural constraints or choke points and propose improvements
- Translate simulation results into clear requirements and guidance for capacity planning, rack deployment policies, and operational runbooks
