Senior Software Engineer | Database Optimization

CAST AI is an automation platform that optimises cloud and AI infrastructure at scale. By embedding autonomous decision-making directly into Kubernetes and cloud environments, CAST AI continuously improves performance, reliability and efficiency in production.

More than 2,100 companies already rely on CAST AI, including Akamai, BMW, Cisco, FICO, Hugging Face, NielsenIQ, Swisscom and TGS.

CAST AI operates across 34 countries and has a remote-first culture built around small, highly technical teams. In January 2026, the company achieved unicorn status following a strategic investment from Pacific Alliance Ventures, bringing its valuation above $1 billion.

Databases are still managed manually. Engineers monitor slow queries, decide which indexes to add, tune connection limits and introduce caching, often without being able to prove whether those changes will improve performance in production.

CAST AI is building an autonomous database administrator that can identify problems, recommend improvements and validate that those improvements work before customers rely on them.

As a Senior Software Engineer on the Database Optimisation team, you will work across two core components:

The focus is not simply producing recommendations. Every recommendation needs to be reliable and validated. A stale read, incorrect cache decision or poor index suggestion can affect a customer’s production system, so correctness is central to the role.

You will help shape the architecture, technical direction and roadmap of the autonomous DBA product.

A background check may be conducted at the final stage through our third-party provider, Checkr.

CAST AI does not provide visa sponsorship or work permits for this position.
