Own services end to end: design, build, deploy, monitor, and iterate Contribute to technical and architectural decisions Perform reliability and performance analysis on Golang / Java-based systems Conduct high-quality design and code reviews Work closely with Product, Frontend, and DevOps teams to deliver best-in-class features Contribute to capacity planning and SLO definition Continuously improve scalability, performance, and reliability You'll be building and enhancing data-intensive systems that operate in highly dynamic production environments.
About the Company
This is a modern cloud security startup operating at runtime to protect customer infrastructure using deep system visibility and contextual data.

Unlike traditional tools, the platform leverages runtime insights and eBPF-powered sensors to identify and prioritise real risks enabling customers to detect threats, reduce risk exposure, and respond automatically at scale.
