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

- 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: $80-$130 per hour, based on experience and role fit
