Application Security Engineer

🧭 About Konvu

At Konvu, we’re on a mission to make security invisible, redefining vulnerability management for the agentic world.

As AI begins to generate, test, and deploy code autonomously, legacy security approaches break down. Konvu’s AI agents reason like security engineers: automatically triaging noise, verifying exploitability with evidence, and helping teams focus on what truly matters.

Our agents plug directly into existing scanners and workflows, no rip-and-replace, no new dashboards. We deliver evidence-backed decisions where teams already work, cutting false positives and surfacing exploitable issues with confidence.

Founded by early members of Sqreen (YC W18, acquired by Datadog), we know what it takes to turn deep technical insight into tools developers and security teams actually use.

We’ve raised $5M in Seed funding and are backed by top European and US VCs, as well as leaders from companies like Datadog, GitHub, Docker, Cloudflare, Sumo Logic, and Vanta.

🛠️ What You'Ll Do

As a Application Security Engineer, you’ll own the research and data that powers our automated triage and remediation engine. You’ll:

• Define exploitability: Analyze CVEs, patches, and PoCs to determine what’s actually exploitable in real-world applications.
• Enrich our vulnerability intelligence: Use LLMs, automation, and your own expertise to build a high-quality, continuously improving vulnerability knowledge base.
• Integrate human insight: Develop processes and tooling for human-in-the-loop validation to ensure high accuracy.
• Collaborate with engineers: Work closely with our engineering teams to embed security expertise directly into our AI-driven workflows.
• Stay ahead of threats: Track evolving vulnerability classes, attack techniques, and mitigation patterns to guide product accuracy and roadmap priorities.

👤 Who You Are

You’re someone with a passion for security, embodying ownership, curiosity, and intensity, with the analytical mind to turn raw intelligence into structured insights.

You Likely Have:

• 1+ year of experience in application security, vulnerability research, or exploit analysis.
• Strong grasp of CVE databases, patching processes, and exploit development fundamentals.
• Interest in how vulnerabilities map to real application impact: not just theoretical risk.
• Programming/scripting skills (Python, SQL, or similar) to automate research, validation, or data enrichment.
• Analytical mindset: you notice subtle patterns, inconsistencies, and edge cases others miss.
• Excellent written and verbal communication in English; you can explain complex vulnerabilities clearly.
• Eagerness to work onsite from our Paris office, collaborating closely with our founding team.
• Static/dynamic analysis tools, vulnerability scanners, or security automation.
