- Experience supporting utility energization, load-bank testing, generator testing, and operational readiness activities.
- Experience feeding commissioning findings and lessons learned back into design standards, commissioning procedures, and reference designs.
Preferred:

- Protective relay testing experience (SEL, Client, ABB, Schweitzer, etc.).
- EPMS and SCADA platform experience.
- NETA Certification (II, III, IV), PE License, CxA, CCP, BCxP, or similar credentials.
- Experience commissioning AI, hyperscale, colocation, or modular data center environments.
The Commissioning Team
Examples of key problems the team is working on:
- Stand up the commissioning program for 10s to 100s of GWs of capacity this decade.
- Run commissioning and QA-QC for first-of-a-kind modular data centers.
- Automate Level 4 and Level 5 commissioning.
Role Scope:
- Commission electrical distribution from utility interface to rack: switchgear, UPS, generators, and EPMS from Level 2 through Level 5.
- Write and run test scripts covering protection, transfer schemes, and failure scenarios at full load.
- Oversee NETA testing and vendor startups, verifying results rather than filing them.
- Run integrated systems tests proving the site rides through utility events the way the design says it will.
What We're Looking For:
- You've commissioned electrical systems on mission critical facilities through pull-the-plug testing.
- You read one-lines, protection studies, and coordination curves, and catch errors in them.
- You've run load bank testing at megawatt scale.
- You hold vendors to test standards under schedule pressure.
- Bonus: MV and HV systems. EPMS platforms. Protective relay testing. PE license.
BENEFITS SUMMARY:
Individual compensation is determined by skills, qualifications, experience, and location. Compensation details listed in this posting reflect the base hourly rate or annual salary only, unless otherwise stated. In addition to base compensation, full-time roles are eligible for Medical, Dental, Vision, Commuter and 401K benefits with company matching.

Mid Level Commissioning Engineer Jobs: Frequently Asked Questions
How do I get a mid level commissioning engineer job?
Position yourself around ownership, not just participation. Highlight projects where you led commissioning from factory acceptance testing through site startup, wrote or reviewed commissioning procedures, and resolved technical issues independently. Employers at this level want evidence you can manage scope without constant supervision, so lead your resume with outcomes, equipment types you have commissioned, and any client-facing experience you have handled.
Which companies hire mid level commissioning engineers?
Companies hiring mid level commissioning engineers right now include Amazon, Jobot, and EPS, based on current listings on Migrate Mate as of August 2026. At this level, hiring covers large engineering and construction firms, industrial equipment OEMs, and specialized commissioning contractors that staff long-term capital projects.
Are there remote mid level commissioning engineer jobs?
Yes, though most commissioning work is inherently site-based. About 20% of mid level commissioning engineer openings are remote or hybrid as of August 2026, and those roles tend to cover document control, engineering review, or project coordination duties rather than hands-on startup work. Fully remote positions are the exception, not the norm, at this level.
How do I move up to a mid level commissioning engineer role?
The progression from entry level to mid level is built on demonstrated ownership. Focus on expanding the systems you commission, volunteering to lead smaller startups independently, and developing expertise in the documentation and safety protocols your sector requires. Measurable impact matters: engineers who can point to successful system handovers, punch-list closures they managed, and client sign-offs they earned make a clear case for the mid level step.
Which industries hire the most mid level commissioning engineers?
Mid Level commissioning engineer roles concentrate in Consulting & Professional Services, Technology & Software, and Staffing & Recruiting, based on current listings on Migrate Mate as of August 2026. Those sectors drive demand because they rely on large-scale facility buildouts, equipment installations, and regulatory startup requirements that need engineers experienced enough to own the commissioning process rather than simply assist.
