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! What you will do: - Design, build, and improve systems that provide deep visibility into endpoints and environments. - Develop and optimize collection sensors that run at scale across hundreds of thousands of devices. - Write low-level components and system-level code when needed. - Own features end to end, from design through production and ongoing improvement. - Work closely with product, research, and field teams to respond quickly to real customer needs. - Drive fast iterations within a product that is actively being built and evolving. - Contribute to the technical direction of the discovery domain within the platform. Requirements: - 3+ years of experience in Endpoint Security or developing low-level system code. - Strong understanding of operating systems and endpoint environments. - Hands-on experience working close to the system level (low-level development). - Solid backend development skills and experience building production systems. - Ability to work in a fast-moving environment and respond quickly to field and customer needs. - Strong technical problem-solving skills and a collaborative, team-oriented mindset. Experience with the following is a plus: - Security research experience. - Experience building endpoint sensors, vulnerability scanners or EDR agents. ## About Zafran Security ## Company Overview - **One-liner**: Zafran Security provides an AI-native Threat Exposure Management platform that unifies vulnerability data, assesses exploitability in context, and automates mitigation and remediation using existing security controls. - **Entity Type**: Private (Series C) - **Headquarters**: New York, New York, United States [linkedin.com] - **Founded**: 2023 (inferred from initial seed funding in early 2024) [linkedin.com] - **Founders**: Sanaz Yashar (CEO) and Ben Seri (CTO) [zafran.io/about] ## Core Business - **Primary industry**: Cybersecurity (vulnerability / exposure management) - **Target customers**: Enterprise security teams (Fortune 500 and high-growth companies) [zafran.io/platform] - **Mission or purpose statement**: “Proactively stop the exploitation of vulnerabilities, everywhere.” [zafran.io/about] ## Products & Services - **Zafran Threat Exposure Management Platform** (SaaS / agentic): End-to-end platform that unifies findings across cloud, on-prem, and AppSec; assesses risk using runtime presence, reachability, exploitability, asset criticality, and existing controls; enables proactive exposure hunting; provides mitigation guidance that leverages compensating controls; and automates remediation via RemOps (generative AI‑powered remediation operations). [zafran.io/platform] - **Zafran Detector** (released Aug 2025): Continuous vulnerability discovery tool that supplements existing scanners.
