ppINTEC Energy Solutions delivers best-in-class services in Engineering, Procurement and Construction (EPC), Battery Energy Storage Systems (BESS), Project Development, Consultancy, and Operation Maintenance, along with New Energy Solutions. With a globally experienced team, INTEC has managed over 200 projects and achieved an installed and secured capacity of 5 GW. Headquartered in the United Kingdom, INTEC also operates offices in Germany, Türkiye, Spain, Azerbaijan, Romania, Mauritius, Mauritania, Australia, New Zealand and the Philippines, with plans for further expansion. /ppWe are seeking a Senior Tendering Engineer to lead the technical definition and engineering estimation of utility-scale Solar PV EPC tenders (and of photovoltaic projects with storage). Based in Madrid, the role has a global scope, supporting bids across all of INTEC's international markets. /ppThis is a senior, hands‑on technical role at the core of the tendering process. The Senior Tendering Engineer is responsible for the technical solution of each offer: the plant design assumptions, the energy yield base case, the performance framework and the complete Bill of Quantities that feeds the project cost sheet. The successful candidate must be able to produce a Bill of Quantities (BoQ) for a utility‑scale photovoltaic project independently and end‑to‑end, master the energy yield Base Case and the production scenarios (P50/P90), and have a thorough command of performance and Performance Ratio (PR) testing for photovoltaic plants. This position works in close coordination with the international technical hubs, the Senior Bid/Proposal Manager and the Integral Director of Business Development. /ph3Key Responsibilities /h3ulliLead the technical engineering definition of utility‑scale Solar PV and PV‑plus‑BESS EPC tenders across INTEC's global markets. /liliProduce the complete Bill of Quantities (BoQ) for photovoltaic projects independently and end‑to‑end, from the layout and electrical design assumptions to the detailed material take‑off. /liliBuild, own and defend the energy yield Base Case,



including PVsyst modeling and production scenarios under different probability‑of‑exceedance cases (P50/P75/P90). /liliDefine and review the performance framework of each offer, including Performance Ratio (PR) guarantees, the design of capacity/performance tests and the acceptance criteria for photovoltaic plants. /liliTranslate the technical scope into structured, accurate engineering inputs that feed the project cost sheet and pricing matrix. /liliCoordinate and consolidate inputs from the international technical hubs, ensuring consistency, completeness and technical quality across disciplines. /liliAnalyze the tender technical documentation (specifications, grid codes, single‑line diagrams, geotechnical and site data) to identify risks, gaps and optimization opportunities. /liliOptimize the technical solution to improve competitiveness while preserving deliverability and compliance. /liliSupport the Senior Bid/Proposal Manager in preparing technical proposals, clarifications and the technical narrative of each offer. /liliEngage with equipment suppliers (modules, inverters, structures, BESS) to obtain technical data and validate design assumptions. /liliParticipate in client clarification rounds, technical QA and negotiation when required. /liliCapture lessons learned and contribute to the standardization of engineering estimation tools, templates and benchmarks. /liliCollaborate in opening new markets and in proposals to key clients, leading the part related to their area of expertise. /li /ulh3Qualifications /h3ulliUniversity degree in Engineering (Industrial, Electrical, Energy or similar); a postgraduate qualification in renewable energy is an advantage.



/liliProven experience of 5 to 7 years as a tendering/estimation engineer in utility‑scale Solar PV EPC projects. /liliProven ability to produce a complete Bill of Quantities for a photovoltaic project independently and end‑to‑end. /liliThorough command of the energy yield Base Case and production modeling, including PVsyst and the P50/P90 exceedance scenarios. /liliSolid knowledge of performance and Performance Ratio (PR) testing, capacity tests and acceptance criteria for photovoltaic plants. /liliSolid knowledge of photovoltaic plant design: layout, structures, DC/AC electrical design, BOS, grid connection and high‑voltage interfaces. /liliExperience with photovoltaic‑plus‑storage (BESS) configurations will be a significant advantage. /liliCommand of PVsyst, PVcase/AutoCAD and advanced cost modeling in Excel. /liliStrong analytical, organizational and coordination skills, with the ability to manage multiple concurrent tenders. /liliExperience coordinating multicultural technical teams and international hubs. /liliFluent in English and Spanish; additional languages will be valued positively. /liliRight to work in Spain or the EU. /liliPassion for sustainability and commitment to quality and innovation. /li /ulh3What We Offer /h3ulliCompetitive salary package. /lili22 Annual Leave Days (in accordance with applicable local legislation, excluding public holidays). /liliOpportunity to join a rapidly growing and leading global company in the renewable energy sector. /liliA dynamic and collaborative international work environment. /liliProfessional development and career growth opportunities. /liliThe chance to play a decisive role in shaping competitive strategy and driving global project success. /liliWe are an Equal Opportunity Employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. Applicants from all backgrounds are encouraged to apply. /liliJoin us at INTEC Energy Solutions and be part of a transformative era where we redefine energy for future generations. Together, we can create a sustainable and eco‑friendly future. /li /ul /p #J-18808-Ljbffr
