Backend Engineer – Discover Team
Zafran · Tel Aviv · onsite
Zafran is looking for an experienced Backend Engineer to join our Discover Team, a highly impactful team that builds the asset discovery and endpoint intelligence the platform relies on. The team plays a critical role in a product that is actively being built and evolving, working closely with the business and responding quickly to field needs.
In this role, you will build and optimize collection sensors that run across hundreds of thousands of devices, gathering rich system data through low-level system interactions. You’ll shape a core part of the platform, from the code on the endpoint to the data the product acts on.
About Zafran:
Our Mission: To stop the exploitation of vulnerabilities, everywhere.
What makes us different: Zafran de-risks 90% of critical vulnerabilities overnight across your hybrid environment and utilizes Agentic Capabilities and your existing security tools to rapidly mitigate and remediate the 10% most likely to be exploited.
Who’s behind us: Zafran is backed by Menlo Ventures, Sequoia Capital, Cyberstarts, and a deep belief that cybersecurity should move as fast as attackers do. We’re one of the fastest-growing companies in the industry, scaling to meet demand from the world’s most advanced, security-obsessed organizations.
We’re serious about our mission- so expect work that matters, teammates who challenge and inspire you, and plenty of fun along the way!
