Staff AI Security Engineer

About Agoda At Agoda, we bridge the world through travel. Our story began in 2005, when two lifelong friends and entrepreneurs, driven by their passion for travel, launched Agoda to make it easier for everyone to explore the world. Today, we are part of Booking Holdings [NASDAQ: BKNG], with a diverse team of over 7,000 people from 90 countries, working together in offices around the globe. Every day, we connect people to destinations and experiences, with our great deals across our millions of hotels and holiday properties, flights, and experiences worldwide. No two days are the same at Agoda. Data and technology are at the heart of our culture, fueling our curiosity and innovation. If you’re ready to begin your best journey and help build travel for the world, join us. Get to Know Our Team The Security Department oversees application security, compliance, GRC, and security operations for all Agoda. We are vigilant in ensuring there is no breach or vulnerability threatening our company or endangering our employees in order to keep Agoda safe and protected. This would be a great challenge for those who want to work with the best technology in a dynamic and advanced environment. The Opportunity You will be joining the AppSec Engineering team at a pivotal moment: AI is changing both how we defend Agoda and what we need to defend. As an AI Security Engineer, you will build AI-powered security engineering capabilities that let a lean team secure a fast paced DevSecOps environment where code ships continuously, and you will make sure the AI systems and agents Agoda builds are secure by design. This is a builder's role with a primary focus on security engineering and threat modeling: you will ship and own production systems, not just own one-off scripts. What You Will Do • Design, build, and operate AI-powered security engineering systems, such as LLM-driven secure code review, finding triage and de-duplication, and automated fix suggestions, and own them end-to-end in production. • Build AI-assisted threat modeling that scales our design reviews: drafting threat models from design docs and architecture, flagging high-risk changes, and routing the reviews that need a human in the room. • Harden the AI developer platforms our engineers use every day, such as Cursor, Codex and Claude, always-on agent platforms including MCP/plugin governance and policy controls. • Lead security design reviews and threat modeling for the AI systems and agents built at Agoda, including LLM-integrated products, RAG pipelines, MCP/tool integrations, and internal agentic platforms. • Define and implement security controls and guardrails for AI agents: agent identity and delegated credentials, least-privilege tool access, sandboxing, human-in-the-loop approval for risky actions, and audit logging. • Develop defenses against AI-specific threats such as prompt injection, data exfiltration through tools, insecure output handling, and model and supply chain risks, and turn them into secure-by-default patterns and standards for engineering teams. • Build agentic security tooling that automates AppSec workflows end-to-end, from intake and risk scoring to ticketing and remediation tracking, keeping outcomes measurable, auditable, and safe. • Measure and continuously improve the quality of our AI security tooling (precision, coverage, false-positive rate) by tuning models, prompts, and pipelines. • Partner with product, platform, data, and AI engineering teams as an embedded security owner, and work closely with AppSec analysts to turn their findings into scalable, automated fixes. • Stay ahead of AI security research and industry frameworks, and share what you learn across Agoda's engineering community. What You Will Bring • Software engineering and
