Zusammenfassung

Lever, Inc. is seeking a Staff Security Researcher based in Switzerland.

The role focuses on turning advanced vulnerability and malware research into production-ready detections for web apps, APIs, cloud-native environments, and AI-powered systems. You will author detection rules with OpenGrep, extend analysis to more languages, build evaluation harnesses, and collaborate with engineering, product, and AI/ML teams to deploy secure solutions.

Qualifikationen

• 8+ years of experience in offensive security or application security research.

Aufgaben

• 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 coverage, accuracy, exploit reproducibility, and false-positive rates.
• Triage complex findings and packages from the analysis pipeline and validate detection results.
• Apply established detection and exploitation principles while contributing to new research standards, policies, and attack methodologies.
• Explore emerging tools and techniques for detecting threats and malware at scale.
• Research security topics across AppSec, AI red-teaming, offensive AI, LLM vulnerabilities, agent security, MCP security, and cloud-native attack techniques.
• Contribute to internal research initiatives and help shape future security research priorities.
• Publish technical research through blog posts, CVEs, advisories, tool releases, and conference contributions where appropriate.
• Mentor junior and mid-level security researchers on detection writing and exploitation techniques.
• Collaborate with engineering, product, AI/ML, infrastructure, platform, and security teams to ensure research outputs are successfully deployed and maintained.
• Help improve security automation across CI/CD and cloud-native environments while maintaining high detection quality.
