Project engineers must independently model facility loads and validate interconnection capacity to ensure grid readiness before construction begins.

Ryan Mahoney

Why this role is hard · Ryan Mahoney

The hardest part is finding engineers who can turn complex grid data into solid decisions while staying calm when contractors push back. You need someone who actually listens to utility inspectors during interconnection meetings rather than just waiting for their turn to talk. That habit stops expensive redesigns when depot charging loads spike past what the transformers can handle. I see candidates nail the load modeling tests every time, but they completely stall when we ask them to negotiate make ready terms under a tight deadline. Real skill in this role comes down to clear communication and the willingness to shut down unsafe field changes before we bring power online.

Active Listening

Active listening is a deliberate communication competency characterized by fully concentrating on, understanding, responding to, and accurately interpreting both explicit technical directives and implicit operational constraints. In engineering and cross-functional environments, it requires suspending premature judgment, asking clarifying questions that uncover root causes rather than surface symptoms, and systematically synthesizing fragmented or non-technical inputs into coherent frameworks without distortion, omission, or cognitive bias.

Walk me through how you would synthesize conflicting site survey data from an EPC contractor and a municipal utility when finalizing a service entrance layout.

Positive indicators

  • Prioritizes field verification over desk assumptions
  • Outlines a clear validation protocol
  • Maintains neutrality between conflicting parties

Negative indicators

  • Picks one dataset arbitrarily
  • Blames contractor for inaccuracies without checking
  • Proceeds without reconciling the conflict

Coding Test

Live Interview · Coding Test

Without AI

Implement the validation logic. Focus on accurate threshold comparison and clear violation reporting.

Implement `validate_coordination` to check if upstream relay pickup current exceeds downstream fault current with a 1.2x safety margin. Return a list of violations with relay IDs and margin deltas.

With AI

Use AI for syntax, but design for extensibility across relay types and mandatory audit logging. Document your architectural decisions.

Extend the validator to support multiple relay types (inverse-time, instantaneous) and configurable safety margins per voltage class. Implement a clear logging strategy for audit trails and handle edge cases where telemetry data is sparse or contradictory. Explain how you verified AI output against these extensibility and compliance requirements.

Work Simulation Scenario

Scenario. During active construction of a multi-phase transit electrification facility, a conflict has emerged between the life-safety building code requirements for automatic transfer switch (ATS) logic and the high-capacity BEB charger sequencing needed for fleet readiness. You must facilitate a 40-minute decision discussion between two stakeholders to approve a compliant, operational design without delaying the project.

Problem to solve. Drive a cross-functional decision that resolves the ATS logic conflict, satisfies life-safety compliance, and maintains fleet operational readiness within the construction timeline.

Format

cross-functional-decision · 40 min · ~2 hr prep

Success criteria

  • Identify the core technical and operational tradeoffs between ATS sequencing and charger availability
  • Propose a compliant, phased, or engineered solution that satisfies both parties
  • Establish clear handoff protocols, testing milestones, and accountability boundaries

What to review beforehand

  • ATS logic fundamentals and life-safety load prioritization
  • BEB charger sequencing and temporary power constraints
  • Construction phase change-control and compliance review workflows

  • Demand practical, minimally disruptive workarounds
  • Remain open to engineered solutions that protect schedule

Do not

  • Do not concede on core operational requirements without a viable alternative

Motivation. Ensure absolute compliance with NFPA and local fire codes for emergency power transfer and life-safety load prioritization.

Constraints

  • Zero tolerance for life-safety code deviations or unverified bypasses
  • High liability exposure and upcoming municipal inspection deadlines
  • Mandatory sequential transfer protocols for critical loads

Tensions to introduce

  • Reject any temporary bypasses that compromise life-safety sequencing
  • Demand strict adherence to code-compliant ATS logic before energization
  • Threaten stop-work orders if testing or commissioning deviates from approved plans

In-character guidance

  • Cite code sections and prioritize human safety over operational convenience
  • Remain firm but professional, focusing on compliance verification
  • Accept engineered alternatives that include certified testing and documentation

Do not

  • Do not solve the technical design or propose ATS configurations
  • Do not become hostile or issue ultimatums beyond professional boundaries
  • Do not relax code requirements without a certified, testable alternative

Scoring anchors

Exceeds
Structures a clear decision framework, uncovers hidden constraints, proposes a compliant and operationally viable resolution, and establishes firm accountability milestones.
Meets
Facilitates a productive discussion, identifies core tradeoffs, and guides stakeholders toward a workable compromise with minor facilitation gaps.
Below
Struggles to manage competing incentives, fails to clarify constraints, or leaves the conflict unresolved without a clear path forward.

Response time
