Job summary

Nexamp is seeking a Senior Electrical Performance Engineer to improve reliability, availability, and performance across a portfolio of solar PV and BESS assets. You’ll translate field data into optimized settings and operating standards, collaborating with Operations, Asset Management, Controls, and OEMs to maximize asset value.

You will drive protection strategy, diagnose grid-interaction issues with utilities, and lead reliability and loss-reduction initiatives across the fleet.

Qualifications

• Bachelor's degree in Electrical Engineering.
• 7+ years of electrical engineering experience.
• 2+ years of solar and protection relays experience.
• Professional Engineer license is a plus.
• Strong communication and collaboration skills.
• Ability to analyze data and identify root causes.
• Drive for improvements and ownership mentality.
• Ability to build relationships with customers and stakeholders.

Responsibilities

• Own plant protection, controls, and compliance strategy by reviewing and coordinating protection settings across OCPDs, relays, inverters, and plant controllers; managing required setting changes with third-party vendors; and securing utility approvals to ensure safe, reliable operation.
• Engage directly with utilities on complex grid-interaction issues related to protection schemes, relay settings, and plant control behavior; diagnose misalignment between plant and utility protection philosophies; and negotiate technically sound solutions that optimize availability and interconnection compliance.
• Improve system reliability and energy performance by evaluating and optimizing protection schemes, breaker coordination, relay timing, circuit configurations, and inverter control functions (Volt/VAR, Volt/Watt, frequency-watt, ramp rates, ride-through).
• Partner with Engineering to improve design standards and fleet consistency, including relay database templates, equipment specifications, standard drawings, and protection philosophies, with a focus on maintainability, operability, and lifecycle cost.
• Lead data-driven reliability and loss reduction efforts by analyzing inverter logs, relay events, EMS dispatch data, and waveform captures; conducting root-cause and 8D investigations; quantifying production and financial impacts; and recommending corrective actions, upgrades, or repowering strategies.
• Own fleetwide monitoring and diagnostics strategy by refining alert thresholds, logic, and escalation workflows to reduce false positives, minimize alert fatigue, and accelerate incident response.
• Develop analytical models, diagnostic frameworks, and performance standards for Nexamp’s PV and BESS fleet, integrating power systems engineering with data analytics to identify constraints and improvement opportunities.
• Influence organizational capability and decision-making by representing Performance Engineering in cross-functional initiatives, providing actionable feedback to development and engineering teams on design and procurement decisions, and mentoring junior analysts through training and documented best practices.
