This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Staff Security Researcher based in Spain. This role is designed for a hands-on offensive security researcher who can turn advanced vulnerability and malware research into production-ready detection capabilities. You will investigate emerging threats across web applications, APIs, cloud-native environments, and AI-powered systems, translating discoveries into accurate security checks with low false-positive rates. The position combines deep technical research with practical engineering, from exploit proof-of-concepts to detection rules, evaluation frameworks, and attack-chain methodologies. You will also contribute to research standards, security tooling, and the broader application security community through publications and technical contributions. Working across engineering, product, AI/ML, and infrastructure teams, you will help ensure research moves efficiently from discovery to production.



The role offers a high degree of ownership in a fast-evolving security environment where technical curiosity and measurable detection quality are highly valued. Accountabilities: - Create and maintain detection rules, primarily using OpenGrep, to identify novel malware and vulnerability patterns and improve detection accuracy. - Extend security analysis capabilities to support additional programming languages across the analysis pipeline. - Research emerging vulnerabilities, exploitation techniques, cloud-native attack paths, and AI-specific threats, translating findings into production-ready detections. - Investigate modern web applications and APIs, develop proof-of-concept attacks, and convert research findings into deployable security capabilities. - Develop attack-chain templates that connect lower-severity findings into meaningful exploitation paths. - Design and maintain evaluation harnesses, testing frameworks, and benchmarks to measure cov
