How to apply for BESS Engineer

About Intersect Power

Intersect Power is at the forefront of delivering scalable low-carbon solutions for both retail and wholesale energy markets, with a focus on clean electricity and fuels. The company's commitment to high-impact renewable energy projects and its remote-first culture make it an attractive workplace for engineers who want to drive the energy transition while enjoying flexibility.

About the role

As a BESS Engineer, you will lead the entire lifecycle of utility-scale battery storage projects, from initial land acquisition through to commercial operation. You'll design and size systems to meet performance targets, develop models, and integrate storage with generation assets, directly contributing to the reliability and sustainability of the grid.

A typical day

Your day might start with a cross-functional stand-up with development and construction teams to align on project milestones. You'll then dive into modeling a BESS configuration for a new site, reviewing interconnection study results, or drafting specifications for procurement. Afternoons could involve a technical review with a utility or a design iteration based on performance data, all while collaborating via Slack and video calls.

Who Intersect Power is looking for

• An electrical engineer with 3-7 years of hands-on experience in energy storage or power generation, preferably with a master's or PhD.
• Expert in BESS sizing, system design, and performance modeling using tools like PSS/E, PSCAD, or MATLAB/Simulink.
• Deeply knowledgeable about grid interconnection, power systems, and standards such as NEC, NFPA, and IEEE.
• A cross-functional collaborator who thrives in a fast-paced, remote environment and can manage projects from concept to COD.

Tips for this application

• Tailor your resume to highlight specific BESS projects you've led or contributed to, emphasizing your role in sizing, design, and modeling.
• In your cover letter, mention your familiarity with the full project lifecycle—land acquisition through COD—and how you've navigated challenges like grid interconnection.
• Quantify achievements: e.g., 'Designed a 200 MWh BESS that achieved 95% round-trip efficiency' or 'Reduced project costs by 15% through optimized sizing.'
• Demonstrate remote work readiness by noting your experience with collaboration tools (Slack, Jira, Teams) and self-management.
• If you have experience integrating storage with solar or wind, highlight that—Intersect Power works with generation assets.

What to cover in your cover letter

["Your expertise in utility-scale BESS design, modeling, and grid integration, with specific examples of projects you've delivered.", 'Your ability to lead projects end-to-end, including land acquisition, permitting, and commissioning.', "Your knowledge of relevant standards (NEC, NFPA, IEEE) and how you've applied them to ensure safety and reliability.", "Your passion for low-carbon energy and alignment with Intersect Power's mission to provide scalable clean solutions."]

Research before applying

• Review Intersect Power's current project portfolio and pipeline—note any recent BESS announcements or partnerships.
• Understand their approach to integrating storage with renewable generation (solar, wind) and any proprietary technology they use.
• Look into their company culture, especially remote work policies and team structure, via LinkedIn or Glassdoor.
• Check for any news about their funding or growth—they are a scaling company, so understanding their trajectory helps.

Likely interview topics

Based on the job description, expect questions about:

• Walk me through a BESS project you led from concept to COD—what were the key technical and logistical challenges?
• How do you approach BESS sizing for a given application (e.g., energy shifting vs. frequency regulation)?
• Describe your experience with grid interconnection studies and how you ensure compliance with utility requirements.
• How do you stay updated on evolving standards like NFPA 855 or IEEE 1547?
• In a remote team, how do you coordinate with cross-functional stakeholders (e.g., development, construction, finance)?

Common mistakes to avoid

• Don't focus only on academic knowledge—this role requires practical, hands-on project experience; emphasize real-world results.
• Avoid being vague about your role in past projects; clearly state whether you led, designed, or modeled, and quantify impact.
• Don't ignore the remote aspect; if you're not experienced with remote collaboration, acknowledge your adaptability and tools you use.
