Commissioning Mechanical Lead, Data Centers

DevOps Engineer

• Deploy and validate data center network infrastructure (front-end, back-end, BMS, management): configure switches, install and validate optics, coordinate cabling, and drive deployments to completion.
• Ensure physical connectivity meets production standards: coordinate fiber remediation, validate insertion loss and OTDR traces, troubleshoot optical-layer issues, and document as-builts.
• Manage hardware logistics: device staging, rack/stack coordination, RMA, DCIM updates, inventory, and vendor shipments so devices are ready when deployments need them.
• Partner with DC Operations, ICT, Hardware, and Network Engineering to identify blockers early, escalate decisively, and keep multi-team efforts on track.
• Maintain cutsheets, as-builts, validation results, and lessons learned, and contribute to the deployment playbook that lets the team scale.
• Provide operational support during and after deployments: incident response, troubleshooting, and break-fix.

Sourcing Lead

Project Manager

• Drive the planning, budgeting, and risk-management engine behind global data centers, turning capacity targets into executable project plans and keeping every stakeholder aligned from kickoff to customer handover.
• Build integrated schedules (Primavera P6, MS Project) across design, procurement, construction, and commissioning, and own the master construction schedule from site mobilization through substantial completion and turnover.
• Own project budgets, cash-flow forecasts, and change-order governance, and report earned-value KPIs weekly.
• Facilitate phase-gate and design reviews, maintain RACI matrices and action logs, and manage contract lifecycles: RFP, bid analysis, award, PCO tracking, and close-out.
• Identify critical-path and long-lead risks (transformers, chillers, switchgear) and drive mitigation, and act as the single source of truth for internal leadership and external partners.
• Lead cross-functional delivery teams (project managers, construction managers, superintendents), develop staffing plans, and run standups, reviews, and retrospectives.

Senior Project Manager

• Drive end-to-end delivery of utility-scale solar and BESS projects from development handoff through commercial operation, owning budget, schedule, scope, and risk across civil, electrical, substation, gen-tie, and interconnection workstreams.
• Build and own integrated project schedules (Primavera P6, MS Project) across engineering, procurement, construction, and commissioning, and maintain the master schedule as the single source of truth from site mobilization through energization.
• Own project budgets, cash-flow forecasts, and change-order governance, report earned-value KPIs weekly, and flag cost and schedule deviations with recovery options before they compound.

Pre-Construction Manager

Executive

Project Executive

• Take the on-call escalation when a site hits trouble and triage it virtually, using real knowledge of the team and the systems to decide what to escalate, when, and how to keep the field crew focused without burying them.
• Get on a plane when it matters: travel site to site (50%+) to work live incidents and post-incident reviews on the floor, and bring the practices that worked elsewhere with you.
• Own root cause analysis on significant events through to closure and track corrective actions to done, killing the underlying class of failure rather than the one instance in front of you.
• Read the patterns across the fleet’s incidents and RCAs, push the few highest-value learnings through to closure, and stay honest about what’s achievable and what to drop instead of boiling the ocean.
• Carry learnings and practices from one campus to the next so a fix at one site becomes the standard everywhere before the failure repeats.
• Write the operational Assessment standard and audit each campus against it, feeding what you find straight back into the corrective-action loop.

Principal Operations Engineer – Reliability, Data Center Operations

Full-stack Engineer

• Lead, coach, and develop a multi-disciplinary team of delivery and lifecycle engineers; own hiring, onboarding, performance management, career development, and retention.

• 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.
• 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 of mechanical and electrical infrastructure.
• Chair the site Change Control Board; own the process, cadence, quorum, and decision record.
• Review and approve all technical changes to data center systems and to the way those systems operate, including BMS/EPMS logic changes, setpoint and Sequence of Operations changes, electrical topology changes, and mechanical configuration changes.
• Set the standard for what a CCB-grade change package looks like: risk assessment, blast radius, MOP/SOP/EOP impact, rollback plan, validation criteria, and communications plan.
• Ensure every approved change is properly documented, executed against an approved MOP, validated, and reflected in as-builts, point lists, one-lines, and program backups.
• Track CCB throughput, change success rate, and change-induced incidents as engineering KPIs, and drive continuous improvement of the change process.
• Serve as the senior technical escalation point for the Operations team across all disciplines; lead root-cause analysis on complex, cross-system faults and drive corrective actions to closure.
• Review and approve MOPs, SOPs, and EOPs authored by Operations or vendors; own the engineering content of those procedures even though execution sits with Operations.
• Analyze trend, historian, and alarm data across BMS/EPMS/DCIM to identify degradation, tune performance, and convert findings into CCB-approved changes.
• Lead engineering participation in incident response, drills, and post-incident reviews; ensure lessons learned land as documented changes, not tribal knowledge.
• Maintain the engineering source of truth for the site: as-builts, one-lines, point lists, Sequences of Operations, controls program backups, and the asset and documentation library.
• Ensure all engineering and delivery work is performed in compliance with NFPA 70E, including PPE selection, arc flash boundary awareness, and energized work permitting.
• Own engineering enforcement of LOTO/LOTOTO procedures for work on or near energized electrical and mechanical equipment, including during construction tie-ins and commissioning.
• Ensure the site meets applicable codes and standards (NEC, NFPA, OSHA) and maintains audit-ready engineering and change documentation.
