Drawing upon an extensive knowledge base, we develop, finance, engineer, build, own, and operate high quality utility-scale photovoltaic projects and battery energy storage projects. Our Engineering team is looking for a talented Senior BESS Engineer to help support the efforts of our fast-growing company. Adapture Renewables is owned by KIRKBI Climate - the private holding and investment company of the Kirk Kristiansen family founded to build a sustainable future for the LEGO® brand through generations.\nOverview\nThis position will work in our Engineering team and serve as ARI's technical resource for battery energy storage across the portfolio-spanning technology and supplier evaluation, system design, delivery, commissioning, augmentation, and operating performance. The Senior BESS Engineer provides storage-specific engineering expertise that complements ARI's engineering team and is the technical backbone behind ARI's storage procurement and design decisions as BESS becomes a core part of the portfolio. The role supports Strategic Procurement with independent technical evaluation of storage suppliers, partners with the development engineering team on integrated system design, and feeds Asset Management the technical inputs needed to operate and maintain the fleet, working closely with Strategic Procurement, Asset Management, Pre-Construction, Construction, and Development. This role reports to the Head of Engineering. The candidate may be based in Oakland, CA or remotely in the U.S., with periodic travel to projects and OEM/factory sites.\nCore Responsibilities\nLead independent technical evaluation of energy-storage suppliers and technologies-cells, modules, enclosures, PCS, and EMS/BMS-across the major OEMs (e.g., Fluence, eStorage, Wärtsilä, Tesla, LG, Samsung).\nDefine technical specifications and requirements for BESS RFPs and support Strategic Procurement's supplier selection with technical scoring, due diligence, and risk assessment (Procurement owns the RFP process and commercial terms; this role owns the technical evaluation and specification that feed them).\nReview supplier proposals, datasheets, and technical exhibits; identify performance, round-trip efficiency, safety, degradation, and warranty risks before they are contracted.\nSupport contract negotiation on technical terms: capacity and energy guarantees, degradation and augmentation, round-trip efficiency, availability, and performance-testing protocols.\nExecute BESS electrical and system design review across projects: DC and AC architecture, PCS sizing, augmentation planning, auxiliary loading, thermal/HVAC, and fire and safety design.\nInterface with civil, electrical, and interconnection design so that storage integrates cleanly with the plant and the point of interconnection.\nDevelop and maintain ARI's BESS design standards, technical requirements, and evaluation criteria as reusable internal assets.\nSupport Project Management and Construction on BESS technical issues through factory acceptance testing (FAT), site acceptance testing (SAT), and commissioning.\nSupport performance testing and capacity and availability verification at commercial operation.\nSupport Asset Management on operating storage performance: degradation tracking, augmentation timing, availability and performance analysis, and technical substantiation of warranty claims.\nDirect technical inputs into ARI's operating-performance framework for the storage fleet.\nEnsure compliance of BESS safety requirements, including NFPA 855, UL 9540 and UL 9540A, hazard mitigation analysis, and technical input to emergency response plans.\nCoordinate with authorities having jurisdiction (AHJs) on storage safety requirements.\nQualifications and Experience\nBachelor's degree in electrical engineering, mechanical engineering, or a related field.\n5-8+ years in utility-scale battery energy storage engineering-design, integration, or technical evaluation-with hands-on exposure across multiple ESS suppliers or technologies.\nDeep working knowledge of lithium-ion BESS architecture: cells, modules, enclosures, PCS, EMS/BMS, augmentation strategy, and degradation behavior.\nDemonstrated ability to evaluate and compare ESS OEM offerings on the technical merits and to defend technical positions against sophisticated suppliers.\nWorking knowledge of BESS performance guarantees, testing protocols, and warranty structures.\nFamiliarity with NFPA 855, UL 9540 / 9540A, and relevant IEEE standards.\nAbility to operate independently and lead cross-functional technical work with Procurement, Asset Management, and Construction.\nProfessional Engineer (PE) license preferred.\nExperience with both solar-plus-storage and standalone BESS configurations preferred.\nFamiliarity with ISO/RTO market-participation requirements for storage as they affect sizing and dispatch preferred.\nExperience developing long-term augmentation and capacity-maintenance strategy preferred.\nMust be willing to travel as needed, up to 25% of time.\nBenefits Package\n401(k) plan with company matching contribution\nCompetitive health, vision, and dental benefits\nAttractive personal time off and company holiday package\nWork-from-home policy\nSalary commensurate with experience\nNote\nQualified candidates only.
