Performance Engineer
About You We are seeking an experienced, data-driven Performance Engineer to selectively analyze and manage the performance of our growing portfolio of over 600 solar and BESS assets across the United States. You will report directly to the Senior Manager of Analytics & Asset Management, working alongside a small team of monitoring analysts that serve as the operational intelligence layer for the entire organization. Approximately 70% of your time will be spent identifying underperformance by interpreting production and weather data, trend analysis, quantifying energy losses, and coordinating with Regional Asset Managers (RAMs) to drive resolution. The remaining 30% focuses on admin work like the digital onboarding of new sites into our analytics ecosystem—ingesting pro-formas and PVSyst models, validating AlsoEnergy Advanced Site Configurations, and assessing as-built drawings to ensure every site is set up correctly from day one. You will work daily inside our Power BI dashboards, internal monitoring systems, Snowflake data tables, and DAS platforms (AlsoEnergy, SolarEdge, SCADA) to surface insights that protect revenue and improve fleet health. This is a role for someone who can look at a site producing at 85% Performance Ratio and immediately start asking the right questions: Why is a site underperforming if all inverters are operational? A soiling issue? A weather anomaly? A data gap? If you thrive on pattern recognition, root-cause investigation, and translating data into action—this is your role.
About Us
We’re one of the fastest-growing solar asset owners in the country. We manage hundreds of commercial and industrial solar sites across the U.S. We believe that the people in the field, in the weeds, and in the office deserve just as much respect as the folks in the boardroom. We’re serious about performance, safety, and world-class operations of our solar and battery fleet.
Key Responsibilities
Performance Analysis & Underperformance Detection (50%) Analyze weekly, and monthly production data across ~600+ solar and BESS sites using Power BI dashboards and monitoring systems. You will not be monitoring every site, you will be looking for trends that our monitoring analysts didn’t catch. Evaluate key performance metrics including Performance Ratio (PR), Weather-Adjusted PR, insolation gap, availability, capacity factor, and forecast-vs-actual variance to assess site health. Investigate root causes of underperformance—distinguishing between equipment failures, inverter outages, soiling/snow loss, weather anomalies, curtailment, and data quality issues. Flag confirmed underperformance to the appropriate Regional Asset Manager with clear, concise summaries of the issue, affected capacity, estimated performance loss, and recommended next steps. Monitor sub-inverter-level performance across the fleet to detect issues, string-level degradation, and equipment-specific trends that site-level metrics may obscure. Track and follow up on open issues to ensure timely resolution Contribute to monthly production reporting, including data validation, cleaning flags, and variance commentary. Reporting & Data Insights (20%) Support weekly and monthly reporting workflows. Prepare variance analyses comparing actual production against P50/P75 forecasts (Models) and flag sites trending below expectations. Analyze weather data (POA irradiance, GHI, Solcast actuals) alongside production to separate weather-driven shortfalls from controllable losses. Document recurring underperformance patterns and contribute to the team’s institutional knowledge base for fleet-wide trend analysis. Administration & Data Organization (50%) Digitally onboard new sites into the analytics ecosystem as they reach operations, ensuring all performance baselines are established. Ingest and validate pro-forma and PVSyst energy models, mapping expected production, degradation assumptions, and design parameters into the ecosystem Validate AlsoEnergy Advanced Site Configuration (ASC) files against as-built drawings and equipment schedules—confirming inverter counts, string configurations, meter assignments, and sensor mappings are accurate. Assess and ingest as-built electrical drawings (single-lines, string layouts, combiner maps) to build a complete digital representation of each site’s equipment hierarchy, and identify/flag discrepancies between design documents, ASC configurations, and actual DAS data feeds—coordinating corrections with the DAS provider or O&M team before the site enters active monitoring. What You Bring 5+ years of expert-level experience in commercial and utility solar monitoring using DAS/SCADA platforms (AlsoEnergy or Power Factors strongly preferred, not residential platforms like Enphase and SolarEdge that lack electrical production details needed for advanced analysis). Deep understanding of solar performance metrics: Performance Ratio, availability, capacity factor, insolation, degradation, and inverter-level diagnostics. Demonstrated ability to interpret production and weather data to identify underperformance, distinguish equipment issues from environmental factors, and quantify energy losses. Experience reading and interpreting PVSyst models, pro-forma energy projections, single-line diagrams, and string layout drawings. 1+ year of experience using Power BI preferred. Strong proficiency with Microsoft Excel and the broader Microsoft suite. Excellent written English; capable of writing clear, professional issue summaries and email communications. Demonstrated critical thinking: ability to look at a dataset and identify what’s wrong before being told. Enjoys structured , detail-driven work with consistent daily patterns—perfect for someone who enjoys clear routines and predictable execution. Comfortable operating independently with minimal instruction. Organized, detail-obsessed, and proactive about solving problems before they grow. Willingness to work U.S. Eastern hours, including occasional weekends. Technical Setup Requirements Because this is a fully remote role, we require the following: Personal computer (2022 or newer) with minimum specs: Intel i5/Ryzen 5 or better, 8GB RAM minimum, 256GB SSD Hardwired primary internet connection + cellular backup (minimum +10 Mbps, Apply To This Job
