    Why Cast AI? Cast AI is the leading Application Performance Automation (APA) platform, enabling customers to cut cloud costs, improve performance, and boost productivity – automatically.

    Built originally for Kubernetes, Cast AI goes beyond cost and observability by delivering real‑time, autonomous optimization across any cloud environment.

    The platform continuously analyzes workloads, rightsizes resources, and rebalances clusters without manual intervention, ensuring applications run faster, more reliably, and more efficiently.

    Headquartered in Miami, Florida, Cast AI has employees in more than 32 countries worldwide and supports some of the world's most innovative teams running their applications on all major cloud, hybrid, and on‑premises environments.

    Over 2,100 companies already rely on Cast - from BMW and Akamai to Hugging Face and NielsenIQ.

    What's next? Backed by our $108M Series C, we're doubling down on making APA the new standard for DevOps and MLOps, and everything in between.

    About the role

    Cast AI is seeking a skilled senior software engineer with deep expertise in databases. It's more about understanding database underlying technology than just knowing how to use it.

    Knowing the implementation details on transactions, wire protocol, WAL, indexes and many other fundamental database features enables us to build a product around it.

    The candidate will be able to work on a greenfield project with a high impact on the outcome.
