About the Role NovaSource is seeking a Performance Engineer I to support the technical performance of utility-scale solar PV and battery energy storage assets.

In this role, you will help monitor assigned assets, detect and diagnose underperformance, quantify energy losses, and develop practical, data-supported recommendations to improve asset performance and reliability. Your primary focus will be performance analysis and diagnostics, supported by customer communication, reporting assurance, and technical studies.

The position combines data analysis with engineering problem-solving. You will work under the guidance of experienced engineers and alongside cross-functional teams to understand the causes of underperformance, prioritize risks by energy and financial impact, and evaluate whether corrective actions deliver the expected results.

This is an early-career engineering role with structured training and development. It is suited to someone with strong analytical fundamentals, an interest in renewable energy technologies, and a willingness to build deep technical expertise in solar PV and battery storage (BESS) performance.

Key responsibilities

Performance Intelligence & Diagnostics Monitor assigned solar PV and BESS assets to proactively detect underperformance and investigate energy losses and equipment issues. Perform root-cause assessments, help prioritize risks by energy and financial impact, and develop quantified corrective-action recommendations under the guidance of senior engineers.

Asset Value Enhancement Support performance modeling, degradation and loss studies, and asset optimization initiatives under supervision. Identify improvement opportunities, estimate recoverable energy and financial value, and help verify that implemented corrective actions deliver the expected results.

Customer Support Support performance and business reviews for assigned customers. Respond to technical inquiries and help prepare clear technical narratives on performance, operational risks, guarantee exposure, and improvement opportunities. Escalate complex or sensitive customer issues to senior engineers for guidance.

Reporting Assurance & Performance Governance Prepare and review performance reports, KPIs, and contractual calculations, using standardized and automated tools wherever available. Validate data quality and calculation integrity, investigate discrepancies, and help apply consistent KPI definitions and measurement practices.

Organizational Support & Capability Building Collaborate with Operations, Asset Management, and other cross-functional teams on technical investigations, asset onboarding, performance testing, and engineering studies. Contribute to technical documentation, standards and playbooks, lessons learned, and knowledge sharing, and support the validation of analytical tools.

Professional Development Work under the guidance of senior Performance Engineers, with structured training and regular technical review of your analyses and recommendations. Build depth in solar PV and BESS performance, contractual KPIs, and analytical tools, and progressively take on more independent ownership of assigned assets.

Minimum qualifications

• Master’s degree in electrical, Mechanical, Energy, Renewable Energy Engineering, or a related technical discipline preferred. Candidates with a bachelor's degree and 2+ years of professional experience in the Solar PV and BESS energy industry will also be considered.
• Early career experience through academic work, internship, research or professional projects involving technical analysis and datasets.
• Foundational understanding of solar PV and BESS operation and relevant metrics; willingness to develop proficiency across both technologies.
• Ability to use spreadsheets and relevant analysis/query/visualization tools; Proficiency in Python, SQL, Power BI or similar tools is beneficial.
• Familiarity with SCADA, historians, energy modeling, performance ratio, availability, yield, degradation, BESS round-trip efficiency and state-of-health concepts are beneficial.
• Strong analytical discipline, documentation, communication and willingness to seek review of uncertain conclusions.

Success in the role

• Enjoy working with operational data and solving engineering problems.
• Look beyond identifying an issue to understand its underlying cause and quantify its impact.
• Apply engineering fundamentals to real-world operating conditions.
• Learn new analytical tools and technical concepts, including how to automate repeatable analyses.
• Organize findings and communicate them clearly to technical and non-technical audiences.
• Take ownership of assigned work, ask thoughtful questions, and welcome feedback and coaching.
