Responsibilities

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

Serve 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

Support 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

Define 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)

Drive engineering hand-off packages with clear assumptions and I/O lists

Support FAT/SAT, functional testing, and onsite troubleshooting (electrical, network, and controls)

Balance 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

Maintain 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

Gather information from a wide variety of often disparate sources, analyze and present the information in a meaningful and well-organized fashion

Provide guidance to the Essential Power Group on opportunities for our existing products and services
