Come work at a place where innovation and teamwork come together to support the most exciting missions in the world

Principal Security Researcher – Threat Defense
Location: Pune, India (Hybrid) / Remote
Department: Research

The Mission
We are seeking a Security Researcher who is a builder, not just an analyst. Bridging the gap between advanced threat research and active defense, you will lead a R&D; mandate to design engines that pinpoint real customer risk. You bring a rare blend of deep security expertise (Zero-days, CVEs, Exploits) and software engineering rigor to drive operational excellence at scale.
You will serve as a key player in our Research Department, moving beyond standard vulnerability analysis to build next-generation detection capabilities. Your work will directly influence our threat defense engine.

What You’ll Be Doing:
- Conduct deep-dive research into emerging attack vectors to analyze vulnerability data and identify potential attack paths.
- Assess vulnerability risks to develop tailored,



actionable mitigation strategies and plans that address security gaps in critical systems.
- Rapidly architect and build prototypes, PoCs, and detection tools. You won’t just theorize; you will write code (Python/Go/C) to test security hypotheses and demonstrate feasibility.
- Design and validate algorithms based on network and application telemetry to detect complex exploit primitives (RCE, SQLi, Memory Corruption) at the execution boundary.
- Partner with R&D; and Product teams to translate complex research findings into production-grade security features, ensuring our engine evolves faster than the threat landscape.
- Articulate security visions and research findings to the broader community through blogs, webinars, and industry conferences, reinforcing Qualys as a thought leader in the space.

The DNA We Need
We are looking for a technologist with a hacker mindset—someone who loves to explore how things work under the hood and prefers architecting solutio
