BESS Application Engineer

Overview

Are you ready to build your career? Were you an exceptional performer in school? Are you ready to focus on building your career and take on a rewarding challenge? If you’re passionate about any of the areas listed below, we encourage you to apply.

We’re looking for a BESS Application Engineer to bridge customers’ technical needs with bankable, buildable energy‑storage solutions. You’ll 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 and coordinate very closely with Essential Power Sales and the Product Managers. This position 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.

• Solution design & sizing
• Develop right‑sized BESS architectures (battery, PCS/inverter, transformer, switch gear, 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 enablement
• 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
• Grid interconnection & standards
• 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.
• Controls & integration
• 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).
• Project transfer & commissioning support
• Drive 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 schedule
• 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.
• Documentation & governance
• 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.
• Contribute to generational production improvements and planning
