How to Apply for BESS Engineering Lead

at Intersect Power

🏢 About Intersect Power

Intersect Power is a unique player in the energy sector, focusing on scalable low-carbon solutions that deliver clean electricity and fuels to both retail and wholesale markets. Unlike traditional utilities, they integrate development, financing, and operation to drive commercial-scale decarbonization, making them an ideal workplace for engineers passionate about tangible climate impact through innovative energy storage and generation projects.

About This Role

As the BESS Engineering Lead, you will own the technical design and system performance for utility-scale battery energy storage projects, ensuring they meet financial and operational targets from development through operation. This role is impactful because you'll directly influence project viability, optimize costs via LCOE/LCOS, and serve as the technical authority in PPA negotiations and financing, bridging engineering with commercial strategy at a company scaling clean energy infrastructure.

💡 A Day in the Life

A typical day involves leading system sizing and electrical modeling for a hybrid ESS project, collaborating with Development and Finance teams to align design with cost and land use targets, and reviewing technical requirements for an upcoming EPC RFP. You might also analyze equipment options to advance technology standards, then prepare materials for a PPA negotiation or IE diligence session, ensuring storage systems meet long-term performance and financial assumptions.

🎯 Who Intersect Power Is Looking For

  • An electrical engineer with 4+ years leading technical scope for utility-scale PV or battery storage projects, experienced in development, design, contracting, and construction phases.
  • Possesses deep, practical expertise in lithium-ion battery systems, including chemistry trade-offs, system architecture, cost drivers, lifecycle analysis, and on-the-ground construction challenges for grid-scale applications.
  • A cross-functional leader who can quantify technical risks/opportunities and align design with Development, Land, Finance, and Procurement teams to balance cost, performance, and constructability.
  • Skilled in technical commercial strategy, such as defining requirements for EPC RFPs, supporting PPA negotiations, and leading IE diligence for project financing in the energy storage sector.

📝 Tips for Applying to Intersect Power

1

Quantify your impact on past utility-scale PV or BESS projects—specify how your technical leadership improved LCOE/LCOS, mitigated construction risks, or optimized system sizing for financial models.

2

Tailor your resume to highlight experience with lithium-ion battery system architecture, balance-of-system design, and electrical modeling for standalone/hybrid ESS, using keywords from the job description like 'constructability' and 'lifecycle considerations.'

3

Research Intersect Power's project portfolio (e.g., their announced storage initiatives) and mention how your expertise aligns with their focus on scalable, low-carbon solutions for wholesale/retail markets.

4

Emphasize cross-functional collaboration by detailing how you've guided teams across Development, Finance, and Operations in past roles, as this is central to the 'Drive Cross-Functional Optimization' responsibility.

5

If you have experience with PPA negotiations or IE diligence for storage projects, explicitly state this, as it's a key differentiator for the 'Lead Technical Commercial Strategy' aspect of the role.

✉️ What to Emphasize in Your Cover Letter

['Demonstrate your ownership of technical design for BESS projects by citing a specific example where you optimized system sizing or electrical modeling to achieve lower LCOE while meeting offtake requirements.', 'Highlight your ability to bridge engineering and commercial strategy, such as by supporting PPA negotiations or EPC RFPs with clear technical requirements that safeguarded project viability.', "Express alignment with Intersect Power's mission by linking your experience to their focus on scalable low-carbon solutions, noting how your work advances clean electricity and fuels in energy markets.", "Showcase cross-functional leadership by describing how you've identified technical risks/opportunities and quantified impacts for Development, Land, or Finance teams in past projects."]

  • → Look into Intersect Power's leadership team and company culture via LinkedIn or industry reports to tailor your application to their values around innovation and scalability.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk us through how you've sized and optimized a utility-scale BESS system to balance LCOE/LCOS, constructability, and reliability, including specific tools or models used.
2 Describe a time you identified a technical risk early in a storage project's lifecycle and how you quantified its impact and developed a mitigation strategy with cross-functional teams.
3 How would you approach equipment and technology selection for a hybrid ESS project at Intersect Power, considering factors like chemistry trade-offs, cost drivers, and lifecycle considerations?
4 Explain your experience serving as a technical lead in PPA negotiations or IE diligence for project financing, and how you ensured designs met contractual and financial assumptions.
5 Given our remote US setup, how do you effectively guide cross-functional design efforts across Development, Land, and Finance teams without in-person collaboration?

⚠️ Common Mistakes to Avoid

  • Submitting a generic resume that doesn't specify experience with lithium-ion battery systems, utility-scale projects, or cross-functional leadership in development/design/construction phases.
  • Failing to demonstrate quantifiable results in past roles, such as omitting metrics on cost optimization (LCOE/LCOS), risk mitigation, or performance improvements for storage projects.
  • Overlooking the commercial aspects of the role—avoid focusing solely on technical design without showing how you've supported PPA negotiations, EPC RFPs, or financing processes.
