How to Apply for Technical Product Manager, Energy Storage

at Voltus

🏢 About Voltus

Voltus connects distributed energy resources to optimize grid flexibility and combat climate change. As a remote-first company, they focus on scaling behind-the-meter battery storage to enable a cleaner, more resilient grid. Working here means directly contributing to the energy transition with cutting-edge technology.

About This Role

This Technical Product Manager will own and scale the toolchain that takes battery storage proposals from initial sizing to operational deployment, driving down time and cost. The role combines deep expertise in co-optimization and energy markets with hands-on engineering, leveraging AI agents to accelerate workflows. It's an opportunity to define how C&I batteries are deployed at scale.

💡 A Day in the Life

A typical day might start with a standup with engineers to discuss progress on the proposal toolchain, followed by deep-dive analysis of market data to refine co-optimization models. Afternoon could involve pairing with an engineer to prototype an AI agent for automated proposal generation, then reviewing customer feedback from a recent pilot. The day wraps with async updates to stakeholders on key metrics like time-to-proposal and deployment cost.

Practice questions for this role

🎯 Who Voltus Is Looking For

  • Has 3-6 years of PM or TPM experience with direct involvement in battery storage, including fluency in co-optimization (e.g., solar+storage, market participation) and energy markets (e.g., ISO/RTO, demand response).
  • Hands-on with AI agents and AI-enabled workflows, having built or integrated LLM-based tools into product processes (e.g., automated proposal generation, data extraction).
  • Possesses builder instincts: comfortable prototyping in code (Python, SQL) and shipping features, not just writing specs.
  • Thrives in a fast-paced, remote environment, with strong communication skills to align cross-functional teams (engineering, sales, operations).

📝 Tips for Applying to Voltus

1

Highlight specific BESS projects you've worked on, including battery sizing, market participation (e.g., PJM, CAISO), and how you improved time-to-proposal or cost.

2

Describe a concrete example of using AI agents or LLMs to automate a workflow (e.g., generating proposals, analyzing market data) and the impact.

3

Show your technical chops: mention any code you've written for prototyping (e.g., Python scripts for battery modeling, SQL queries for market analysis).

4

Tailor your resume to emphasize 'toolchain' ownership: from customer requirements to proposal generation to deployment handoff.

5

Include metrics: e.g., 'Reduced proposal generation time by 40% using automated co-optimization models' or 'Scaled BESS deployments from 5 to 50 MW in 12 months'.

✉️ What to Emphasize in Your Cover Letter

["Your direct experience in battery storage co-optimization and energy markets, with specific examples of how you've translated technical constraints into product features.", "How you've used AI/agents to solve real problems (e.g., automating repetitive tasks, improving decision-making) and your excitement to apply that at Voltus.", 'Your ability to operate as both PM and engineer—mention prototyping a tool or feature that shipped.', "Alignment with Voltus's mission: connecting DERs to optimize grid flexibility and combat climate change."]

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Understand Voltus's platform: how they aggregate DERs and participate in wholesale markets (e.g., demand response, frequency regulation).
  • → Read about their BESS offering: how they currently handle proposals, sizing, and market registration.
  • → Familiarize yourself with key energy markets: PJM, CAISO, NYISO, ISO-NE—especially rules for battery storage participation.
  • → Look into their use of AI: any public info on their tech stack or AI initiatives (e.g., blog posts, press releases).

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk me through how you would design a toolchain to take a C&I BESS proposal from initial customer inquiry to deployment. What are the key bottlenecks?
2 Describe your experience with co-optimization. How would you model battery sizing for a customer with solar and demand charge management?
3 Give an example of an AI agent you've built or used in a product workflow. What was the problem, and how did you measure success?
4 How do you prioritize features when you have competing demands from sales, engineering, and customers?
5 Tell me about a time you prototyped a solution and validated it with customers. What did you learn, and how did it change your product direction?

⚠️ Common Mistakes to Avoid

  • Don't focus on consumer IoT or software PM experience without connecting it to energy storage and markets—this role requires domain depth.
  • Avoid being vague about AI experience; be prepared to discuss specific tools (e.g., LangChain, OpenAI API) and how you've used them.
  • Don't neglect the 'builder' aspect: if you can't demonstrate prototyping or coding, you'll be seen as too hands-off.
