Technical Sr. Engineer Performance Engineer

Job Description : Responsibilities Lead multidisciplinary R&D teams in solar technology projects driving innovation in PV performance and the integration of emerging technologies such as energy storage and advanced control systems. Conduct operational data analysis of complex PV systems defining and monitoring performance metrics and recommending optimization strategies. Design, implement and manage advanced instrumentation systems for PV plants integrating environmental sensors (irradiance, albedo, temperature) with advanced electrical measurement technologies for high‑precision monitoring of current, voltage and related parameters. Develop firmware and algorithms for dataloggers ensuring robust data acquisition and long‑term operational performance. Oversee image‑based monitoring solutions for PV plants including system sizing and integration with SCADA / PPC environments. Perform outdoor infrared thermography of PV systems according to IEC 62446‑3. Act as a key interface between multicultural cross‑functional teams and external stakeholders ensuring alignment between technical execution and strategic objectives. Requirements Bachelors degree in Energy Engineering, Electrical Engineering or a related field. International academic or professional experience is a strong asset. At least 8 years of combined academic and professional experience in the solar energy sector. Proven track record in solar PV projects with a portfolio of 1000 completed projects across distributed and utility‑scale contexts. Hands‑on experience in at least one utility‑scale solar power plant of 1000 MW or more. Background in M&A technical due diligence supporting portfolios of at least 1 GW. Strong experience in solar R&D including modeling, simulation and experimental validation using advanced instrumentation. Academic or professional exposure to hybrid and renewable systems (e.g. CSP, PV‑biomass integration, hydropower, wind). Active participation in national and international technical standards committees (e.g. IEC, ABNT, COPANT). Hands‑on experience with infrared thermography (IEC 62446‑3) and familiarity with electroluminescence testing of PV modules. Proficiency in PVsyst, pvlib, Python and Design of Experiments. Expertise in monitoring and control systems (instrumentation, dataloggers, SCADA, PPC). Familiarity with data science and computer vision applications for solar performance and AgriPV. Strong knowledge of LCoE, CAPEX and OPEX analysis. Fluent in English and Spanish; native Portuguese speaker.
