What you will do

• Review long-horizon tasks involving data-center cooling, hydronic and process-water systems, coolant distribution units, heat exchangers, HVAC and equipment integration, electrical systems, building controls, and commissioning

• Check engineering assumptions, calculations, code and standards use, equipment data, operating sequences, redundancy, and constructability

• Identify ambiguity, conflicting source documents, missing constraints, or unrealistic deliverables

• Improve task prompts, supporting artifacts, acceptance criteria, rubrics, and programmatic checks

• Produce clear technical findings and validate corrected tasks end to end

Who we are looking for

• Relevant roles include Senior or Lead Mechanical Engineer, Electrical Engineer, Plumbing or Process Engineer, Controls or BAS Engineer, Commissioning Engineer, MEP Design Manager, or Technical Director

• Strong command of data-center systems and relevant codes and standards; PE or a recognized commissioning credential is preferred

• Experience at a leading multidisciplinary, mission-critical, or consulting engineering firm is strongly preferred

• Able to interpret large document sets, drawings, schedules, calculations, equipment submittals, and machine-readable data

• Precise, detail-oriented, and able to explain technical issues clearly in writing

Details

• Approximately 5–10 hours per week initially

• Immediate start

• Compensation: $100–$140 per hour, based on experience and role fit
