BESS Application Engineer

Join to apply for the BESS Application Engineer role at Stryten Energy Overview Were looking for a BESS Application Engineer to bridge customers technical needs with bankable, buildable energy-storage solutions. Youll translate use-cases (peak shaving, solar+storage, microgrids, capacity, frequency regulation, backup power, T&D deferral) into compliant system designs and compelling proposals. Expect cross-functional work with Sales, Product, Project Engineering, EPCs, utilities, and commissioning teams. The Applications Engineer is the top technical/systems representative acting as the final design authority for the Essential Power group. This individual must be able to interpret EP customer specifications and requirements and then perform and analyze site/system power studies to achieve customer approval. This position requires the ability to participate in cross functional teams as well as to track and monitor EP project status. The individual must be able to work across cultural boundaries and be expected to manage customer expectations on a global basis where needed. This position will work closely with Essential Power Sales and Product Managers. It requires a solid understanding of Utility, Sustainability, and Resiliency Energy Storage Market applications as well as a sufficient level of detail of customer needs for new product development. Responsibilities Solution design & sizing Develop right-sized BESS architectures (battery, PCS/inverter, transformer, switchgear, protection, HVAC/fire) for front-of-the-meter and behind-the-meter projects. Model duty cycles, throughput, degradation, and warranty compliance; build dispatch strategies for economics and performance guarantees. Produce single-line diagrams, equipment schedules, and preliminary layouts; specify BoMs and auxiliary systems. Technical sales enablementServe as primary technical liaison between Stryten and Essential Power customers. Lead technical discovery with customers and EPCs; turn requirements into design criteria and assumptions. Work with Sales and Business Development to review technical purchase specifications and prepare quotations. Support the custom order process through generation of bills of material and drawings. Create proposal packs: performance models, losses, round-trip efficiency, degradation curves, availability, and lifecycle cost. Respond to RFP/RFQ/tender documents, author exceptions, clarifications, and compliance matrices. Determine customer qualification requirements and translate into system specifications and recommendations tied to customer approval. Grid interconnection & standardsSupport interconnect studies and applications; coordinate with utilities on protection settings, ride-through, and metering. Ensure designs meet applicable codes/standards (e.g., NEC, IEEE, UL/CSA, NFPA/IFC for energy storage) and site AHJ requirements. Controls & integrationDefine requirements for EMS/SCADA integration, communications (Modbus TCP, CAN, DNP3, IEC 61850), and cybersecurity expectations. Specify control modes (PF/VAR, droop, frequency/watt, volt/VAR, black start, islanding) and verify with the controls team(s). Project transfer & commissioning supportDrive engineering hand-off packages with clear assumptions and I/O lists. Support FAT/SAT, functional testing, and onsite troubleshooting (electrical, network, and controls). Risk, cost, and scheduleBalance technical performance with capex/opex; run sensitivities on cell chemistry, C-rate, enclosure type, HVAC load, and EMS strategies. Identify execution risks (thermal, fire code, interconnect constraints, harmonics, arc-flash) and propose mitigations. Documentation & governanceMaintain templates, calculators, and standards; contribute field lessons back into design guides and product requirements. Present solutions to internal reviewers, lenders/insurers, and customers in a clear, defensible manner. Contribute to generational production improvements and planningGather information from diverse sources, analyze and present the information clearly and organized. Provide guidance to the Essential Power Group on opportunities for existing products and services. Anticipate future opportunities for existing products and new products with backup analysis and confidence rankings. Engage with the Global Engineering group on defining customer technical requirements, ensuring rigorous product qualification testing and proper design control of engineering specifications and standards. Qualifications Leadership, collaboration skills, industry experience Customer-facing communicator, clear writer, structured problem solver, comfortable presenting to technical and commercial audiences Ability to interpret customer technical specifications and industry standards Demonstrated project management experience and participation on cross-functional teams Knowledge of Network Power, Renewables, Microgrid, and Utility market and products (Front of Meter and Behind the Meter) Knowledge of EV+storage interconnectivity and performance via system integration Knowledge of AI/Data Center demands on electrical reliability and mitigation through storage technologies Knowledge of storage applications for disaster relief, long-duration resiliency, and defense requirements Strong track record of influencing decisions and delivering impact Education & Experience Minimum: Bachelors degree in an engineering field (Chemical, Mechanical, or Electrical). Preferred: B.S. in Electrical, Power, Controls, or Mechanical Engineering (M.S and/or PE or EIT a plus). Experience: 3-7+ years in energy engineering with BESS, solar+storage, microgrids, or power systems; pre-sales/applications or project engineering experience preferred. One to three years interfacing with customers in a technical capacity. Technical depth: Battery technologies (Li-ion LFP/NMC; Pb; familiarity with flow or sodium is a plus) and degradation drivers. Power electronics and protection (inverters/PCS, transformers, MV switchgear, grounding, coordination, harmonics, short-circuit/arc-flash basics). Codes/standards: NEC, IEEE 1547/519, UL 9540/9540A, UL 1741, NFPA 855/IFC energy storage provisions, utility interconnection rules. Controls/SCADA/EMS and communications (Modbus, DNP3, IEC 61850), networking fundamentals, and time synchronization basics. Performance modeling tools (Python/Excel, MATLAB/Simulink, PVSyst/HOMER/DER-CAM, HELIOSCOPE, or similar) and bankability metrics (LCOE/LCOS, NPV/IRR). Nice to have: Experience with AHJs and fire marshals, utility interconnect processes, EPC coordination, microgrid/islanding controls, and commissioning.
