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.


The Embedded Systems team is responsible for developing and delivering Zitara Live, our industry-leading software package to deliver adaptive controls software onboard batteries across EV, aerospace, IoT, utility-scale storage applications, and beyond. Zitara Live algorithms are powered by Zitara's proprietary battery models, which apply advanced numerical methods to provide precise, actionable battery insight.

Zitara Live serves a broad range of customers operating across diverse platforms, from small embedded microcontrollers to full POSIX server systems, while meeting high-assurance guarantees and hard real-time requirements. Our work supports flexibility, efficiency, and robustness, and spans all phases of the software lifecycle across algorithm implementation, verification and testing, application packaging for distribution, and incorporating customer feedback.

We are seeking a Staff Software Engineer to join the Embedded Systems team. In this role you will architect and implement complex algorithmic firmware and systems-level software; design and create solutions to make core functionality available across a variety of systems and platforms; and provide guidance on the practical realities of delivering real-time software to multiple customers.

The nature of Zitara Live as a product that supplies capability to our customers’ systems means that our work spans the full range of the software/firmware stack, from bare-metal embedded contexts all the way up to distributed server-based applications. Success in this role can take several forms, and we are interested in candidates with deep domain expertise as well as candidates with a broad experience base.
