Role Overview

We're seeking an Engineering Manager / Senior Engineer to lead the technical execution of Battery Energy Storage System projects across the full project lifecycle — from capacity sizing and development engineering through detailed design and technology selection. This role is a key technical contributor delivering high-quality engineering on standalone and hybrid (solar-plus-storage / wind-plus-storage) projects.

Key Responsibilities

- Perform BESS capacity and sizing studies, including power/energy optimization, duration analysis, and degradation/augmentation modeling over project life

- Lead development-stage engineering, supporting feasibility, site layout, single-line diagrams, and preliminary design for project development teams

- Execute detailed engineering deliverables, including electrical design, equipment specifications, protection schemes, and integration with balance-of-plant systems

- Drive technology selection and evaluation of battery cells/modules, PCS/inverters, EMS, and containerized solutions, including technical due diligence on vendors and OEMs

- Conduct system performance and use-case analysis (energy arbitrage, frequency regulation, peak shaving, capacity firming,



etc.)

- Prepare technical reports, specifications, and documentation, and present findings to clients and internal stakeholders

- Provide technical guidance and mentorship to junior and mid-level engineers

- Ensure designs comply with relevant codes and standards (NFPA 855, UL 9540/9540A, IEEE, NEC, and applicable grid/interconnection requirements)

Requirements

- Bachelor's or Master's in Electrical / Power Systems Engineering or related field

- Solid experience in BESS engineering across sizing, development, and detailed design phases

- Hands-on experience with battery technology selection and vendor evaluation

- Familiarity with energy storage use cases, revenue streams, and system performance modeling

- Knowledge of applicable safety and grid codes (NFPA 855, UL 9540/9540A, etc.)

- Proficiency with relevant tools (e.g., HOMER, PVsyst, PSS®E, PSCAD, ETAP, or sizing/optimization software)

- Robust analytical, written, and verbal communication skills

- Ability to work independently and manage own deliverables within project timelines
