How to Apply for Senior Preconstruction Project Engineer - Battery Storage

at Plus Power

🏢 About Plus Power

Plus Power is at the forefront of the renewable energy transition, specializing in utility-scale battery energy storage systems that stabilize the grid and enable greater integration of renewable sources. Their remote-first culture and focus on cutting-edge technology make them an attractive employer for professionals seeking impact and flexibility.

About This Role

As a Senior Preconstruction Project Engineer, you will lead the technical development of battery storage projects from early-stage feasibility through financial close. Your work directly influences project viability and profitability by assessing technologies, optimizing site layouts, and de-risking designs—making you a critical bridge between engineering and finance.

💡 A Day in the Life

A typical day might start with reviewing a site layout drawing in AutoCAD and marking up access road adjustments to reduce earthwork costs. Midday, you'd join a call with the development team to present a technology comparison matrix for a 200 MW project, then spend the afternoon refining a CAPEX estimate in Excel and preparing slides for an investor presentation. You might end the day by coordinating with an EPC partner on a risk register update.

Practice questions for this role

🎯 Who Plus Power Is Looking For

  • 6+ years of experience in power, energy, renewables, or BESS, with proven ability to lead technical assessments and cost estimation for large-scale projects.
  • Deep understanding of battery energy storage system components, balance of plant, and site layout trade-offs (e.g., containerized vs. modular, AC vs. DC coupling).
  • Proficient in AutoCAD for reviewing and redlining engineering drawings, and comfortable with financial modeling inputs like CAPEX/OPEX estimates and schedule development.
  • Strong communicator who can present technical risks and solutions to stakeholders, including developers, financiers, and EPC partners, and is willing to travel for site visits.

📝 Tips for Applying to Plus Power

1

Highlight specific BESS projects you've worked on, detailing your role in technology selection and cost estimation—use metrics like $/MWh or capacity (MW/MWh).

2

Showcase your experience with financial valuation models: mention any involvement in creating or reviewing inputs for project finance models.

3

In your resume, explicitly list AutoCAD proficiency and provide examples of drawings you've reviewed or created for energy storage or power projects.

4

Tailor your cover letter to mention Plus Power's focus on 'greener grid' and explain how your technical de-risking approach aligns with their project value maximization goal.

5

If you have experience with multiple battery chemistries (LFP, NMC, etc.) or inverter technologies, mention it to demonstrate breadth.

✉️ What to Emphasize in Your Cover Letter

['Emphasize your hands-on experience with BESS technology assessment and site layout optimization to maximize project value.', 'Describe a specific example where you identified and mitigated a technical risk, resulting in cost savings or schedule improvement.', 'Show understanding of the preconstruction phase: how your work feeds into financial close and project execution.', 'Mention your comfort with remote collaboration and willingness to travel for site visits and stakeholder meetings.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Review Plus Power's project portfolio on their website to understand the scale and types of BESS projects they develop (e.g., standalone vs. solar+storage).
  • → Read recent news or press releases about Plus Power to learn about their strategic focus (e.g., ERCOT, CAISO, or specific project milestones).
  • → Understand the competitive landscape: how does Plus Power differentiate itself from other BESS developers (e.g., Fluence, NextEra)?
  • → Look into the company's culture and remote work policies via LinkedIn or Glassdoor to align your application tone with their values.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk me through how you would assess and compare two different battery storage technologies for a 100 MW/400 MWh project.
2 Describe a time you identified a significant technical risk in a project and how you de-risked it. What was the outcome?
3 How do you approach developing a capital cost estimate for a greenfield BESS project? What are the key line items?
4 Explain your experience with AutoCAD. Can you give an example of a drawing review that led to a design change?
5 How do you stay current with evolving energy storage technologies and market trends? What's a recent development you find interesting?

⚠️ Common Mistakes to Avoid

  • Submitting a generic resume without highlighting BESS-specific experience—vague 'energy industry' roles won't stand out.
  • Failing to quantify your impact: avoid statements like 'managed costs' without showing % savings or $ amounts.
  • Overlooking the preconstruction focus: don't emphasize construction or commissioning experience alone; show how you contribute before construction starts.
