Job description

Are you ready to unlock intelligence?

If you don’t think you meet all of the criteria below but are still interested in the job, please apply. Nobody checks every box - we’re looking for candidates that are particularly strong in a few areas, and have some interest and capabilities in others.

About the Role

At Kong, our API and AI Gateway sits at the center of how Fortune 500 enterprises and AI-native startups secure and govern the flow of intelligence.

Every request into a company's infrastructure goes through the Gateway first. Security isn't a side concern here, it's the top priority: you're guarding the front door.

You’ll be securing AI traffic while the playbook is still being written: prompt injection, agentic authorization, MCP. These are problems nobody has fully solved yet.

We’re looking for a Software Engineer with a security specialization to join our Runtimes team as a Security Champion: an engineer who writes real code and makes security a built-in part of how we ship.

What You’ll Do

• Run security-focused code audits, threat modeling, and secure design reviews across our AI Gateway and API Gateway capabilities




• Own vulnerability management end-to-end: triage, reproduction, remediation, verification




• Partner with AI Gateway engineering on emerging AI/LLM threat patterns (ie: prompt injection, data leakage, model abuse)




• Coach engineers on secure coding practices, turning security findings into lasting team habits




• Contribute hands-on to Gateway feature work, with security built-in from day one

What You’ll Bring

• 3+ years building production software, with 2+ years in a dedicated security role (AppSec, vulnerability research, or pentesting);




• Solid coding skills in a object oriented language (Rust, Java, Python, Go, or similar);




• Practical threat-modeling experience;




• Working knowledge of cybersecurity (especially L7 security and authentication);




• Basic knowledge of AI attack vectors.

Nice-to-have

• Familiarity with L7 proxies/API gateway architecture (Nginx, OpenResty, Envoy, HAProxy or Kong);




• Experience with Lua;




• Open-source contributions;




• Willingness to learn Rust is important for where our platform is heading: we’ll help you get there.

What we offer

• A permanent contract under the CCNL Commercio (Quadro)




• Bonus and welfare system




• Hybrid work from our Milan Hub at Talent Garden Isola, and a seat at the table where security decisions actually shape what millions of API calls run through every day.
