Job description

We bring startups and disruptive tech companies to the local market, offering engineers the opportunity to work on innovative, high-impact products. Join us and become a member of their R&D team while we take care of employment, HR support, a benefits package, and an enjoyable work environment.

Orca Security is a cybersecurity startup and cloud innovation leader. Founded in 2019 in Israel by former Check Point managers, it raised $630+ million and became a 'unicorn' in 2021.

As part of Orca cloud security suite, our team is building Orca Sensor — a lightweight runtime component that brings deep visibility and protection to cloud workloads running on Kubernetes, serverless engines and virtual machines.

Our mission is to make cloud security smarter, faster, and easier to deploy, without the burden of traditional agents. If you enjoy solving performance and reliability challenges in modern cloud infrastructure, you’ll feel right at home here.
