Batteries have a big role to play in tackling the climate crisis, and it’s essential to make sure that they’re safe and reliable to operate.

At Zitara (YCombinator S20), we build cutting-edge software solutions that empower companies to deeply understand their batteries, both in design and deployment. It’s all part of our work to enable a renewable energy revolution, powered by safer batteries, at a lower cost, with less waste. Our customers operate >$100M deployments of batteries in satellites, EVs, and renewable energy storage installations.

Our team brings top researchers in physics-based battery algorithms together with seasoned software engineers to build safety-critical firmware and large scale machine learning systems. We bring with us decades of experience from companies like Tesla, Cruise, and Google.


We are looking for a field applications engineer who will ensure successful integration of Zitara’s battery design and management software in customer applications.

This person will act as a bridge between customers and internal teams: they will manage and nurture the customer relationship, develop technical solutions for customers, and aid in product design and development as a customer advocate within Zitara. The field applications engineer must combine robust technical skills with strong emotional intelligence to help customers achieve their goals while strengthening their relationship with Zitara.

  • Provide direct technical support to customers when they encounter difficulty.
  • Create technical solutions for customers, such as data analyses, sample code, or technical documentation.
  • Develop in-depth knowledge of customer needs across the industry, and drive Zitara product development by identifying product gaps and advocating on behalf of our customers internally.
  • Directly participate in Zitara’s product planning and development process.


  • Bachelors' degree in technical subject or equivalent proficiency.
  • Two years of technical experience with energy systems, such as:
    • Power electronics.
    • Renewable energy.
    • Mobility / automotive / aerospace.
    • Industrial equipment / robotics.
  • Strong emotional intelligence that enables relationship building with customers of all stripes.
  • Clear and effective written and verbal communication..
  • High attention to detail and quality in work output.

    • Battery-related applications engineering.
    • Battery hardware or software engineering.
    • Battery management systems.
    • Battery fuel gauge or algorithms.
    • Battery cell research and development.
  • Comfortable programming in Python and/or C.
