Lead MV Electrical Engineer, PE - Power & Infrastructure

Monterra is a new kind of consulting engineering firm specializing in power infrastructure for modular data centers, battery storage, microgrids, onsite generation, and EV charging. Our licensed PEs work with AI agents developed in-house to deliver engineering services faster while remaining in responsible charge of every design.

Since launching the service a few months ago, we've been winning and delivering projects, and our client base is quickly growing.

We're hiring our first MV Electrical Engineer, who will serve as the technical authority and in-house subject matter expert on medium-voltage power systems. You’ll work closely with our Principal Electrical Engineers on projects ranging from modular AI data center deployments and battery storage to heavy-duty truck charging hubs. You’ll own MV technical design, lead the development of our MV engineering standards and processes, and help translate your engineering expertise into the AI-powered workflows that make Monterra different.

In this role, your time will be split across:

• Client project delivery (~60%): full-cycle electrical design, from site layout and one-lines through utility/AHJ review and construction support.

• Discipline building (~20%): establish and continuously improve Monterra's MV engineering standards, design practices, and quality controls.

• Shaping the AI (~20%): set the standards and design rules our AI agents follow, and work with our product & engineering team to make them better on every project.

• Design customer-owned substations and MV distribution for data centers, BESS, microgrids, and large charging sites: develop one-line and three-line diagrams, physical layouts, grounding, and raceway.

• Specify power transformers, breakers, switch gear, reclosers, and instrument transformers.

• Integrate generators and BESS at the MV level, including paralleling and transfer schemes.

• Perform short-circuit, load flow, arc flash, and grounding grid studies, and use the results to drive equipment selection.

• Run the protection coordination study, including relay settings and CT/PT sizing, and develop the MV protection philosophy.

• Familiarity with substation calculations like system X/R calculation, DC Battery System sizing, surge arrestor sizing, and Harmonic Distortion.

• Take MV design packages through utility service and interconnection review.

• Coordinate equipment pads, duct banks, and site layout with our civil engineer.

• Respond to utility and AHJ comments and support construction RFIs and submittals.

• Seal substation and MV sheets on projects where you serve as the engineer in responsible charge.

• Own Monterra's MV engineering standards, including standard details, design templates, and QC checklists.

• Define the technical rules our AI agents follow, review and validate their engineering output, and work with our AI platform team to continuously improve the system.

You're a power engineer who loves and takes pride in your craft, but also a little frustrated by the monotony and the slow pace of change in the industry. You've designed MV power systems end to end, you know what a utility reviewer looks for, and you can lay out a ring bus lineup any day. But you're also the person on your team who is always trying out and evangelizing new ideas and tools, experimenting with new ways of working, and building spreadsheets or scripts to automate your own studies.

If that sounds like you, this could be the right role for you!

• Active electrical PE license, with willingness to obtain comity licensure in other states we work in.

• 7+ years of engineering experience, including…
