Position Overview

As a Sales Engineer, you will support the development of technical solutions for utility-scale battery energy storage system (BESS) opportunities. You will assist with customer requirement reviews, system sizing and configuration, technical proposals, contract documentation, customer engagement, and coordination across Sales, Engineering, Product, Proposals, and Project Execution.

You will learn how customer requirements are translated into technically compliant and commercially competitive energy storage solutions. Over time, you will develop the ability to independently evaluate project requirements, perform system sizing and configuration analysis, identify technical and commercial risks, support customer discussions, and manage the technical aspects of assigned opportunities.

This role is ideal for an early-career engineer who is curious, analytical, and interested in the intersection of engineering, customers, and commercial decision-making. We are looking for someone who is humble enough to ask questions and learn from others, hungry to take initiative and continuously improve, and smart in how they communicate and collaborate.

You will also be encouraged to identify knowledge gaps, improve tools and workflows, document lessons learned, and develop repeatable processes that make the Sales Engineering team more effective.

Primary Responsibilities

Customer Requirements & Technical Solutions

• Review customer RFPs, RFIs, technical specifications, drawings, data sheets, and project documentation to identify requirements, assumptions, exceptions, risks, and required clarifications.
• Support BESS sizing and configuration based on project power, energy, duration, cycling requirements, site conditions, project life, and performance requirements.
• Evaluate technical considerations including battery degradation, augmentation, usable energy, state-of-charge range, auxiliary loads, efficiency, and equipment limitations.

Electrical, Controls & Compliance

• Develop an understanding of BESS electrical architecture and support review of single-line diagrams, equipment ratings, system interfaces, and interconnection requirements.
• Assist in evaluating requirements related to active and reactive power, apparent power, power factor, voltage, current, and equipment capabilities.
• Develop working knowledge of applicable BESS codes and standards, including NFPA 855, UL 9540/9540A, UL 1741, NFPA 70, applicable IEEE standards, and local utility and Authority Having Jurisdiction (AHJ) requirements.
• Coordinate with subject-matter experts when projects require detailed electrical, controls, mechanical, civil, fire-protection, or grid-integration analysis.

Proposals, Contracts & Customer Support

• Prepare technical proposal content including system descriptions, equipment configurations, scope definitions, assumptions, compliance information, supporting calculations, data sheets, drawings, and technical exhibits.
• Maintain alignment and traceability between customer requirements, proposed solutions, technical assumptions, exceptions, and contractual requirements.
• Support technical review of contracts, exhibits, equipment specifications, scopes of work, and performance requirements.
• Assist in identifying technical and commercial risks associated with performance guarantees, warranties, availability, efficiency, capacity, degradation, schedule, and equipment scope.
• Support technical clarifications and contract negotiations to help ensure commitments are consistent with product capabilities and the proposed system design.
• Maintain organized records and revision control for proposals, calculations, technical documents, and customer deliverables.

Customer & Cross-Functional Collaboration

• Participate in customer meetings and technical workshops and progressively take responsibility for presenting solutions and responding to technical questions.
• Communicate system capabilities, assumptions, requirements, risks, and trade-offs clearly to both technical and non-technical stakeholders.
• Work cross-functionally with Sales, Proposals, Product Management, Engineering, Supply Chain, Project Execution, Service, and other teams to develop complete customer solutions.
• Develop experience working with developers, utilities, EPCs, consultants, suppliers, and other project stakeholders.

Opportunity Lifecycle & Project Handoff

• Support opportunities throughout the sales lifecycle, from qualification and RFP response through proposal development, contract support, and project handoff.
• Maintain key technical assumptions, decisions, risks, commitments, and outstanding items throughout the opportunity lifecycle.
• Support structured handoff of awarded projects to Engineering and Project Execution to ensure customer requirements and sales commitments are clearly documented and understood.

Continuous Improvement & Knowledge Sharing

• Take ownership of assigned technical problems, research potential solutions, and engage senior engineers or subject-matter experts when appropriate.
• Identify recurring technical questions, process gaps, and inefficiencies and help develop tools, templates, application notes, training materials, and standardized workflows.
• Capture and share lessons learned so solutions and technical knowledge can be reused across the Sales Engineering team.
• Support continuous improvement of sizing tools, proposal templates, technical databases, automation, and internal documentation.
• Provide feedback on customer requirements and recurring project needs to help inform product and process improvements.
