Senior Security Engineer

Responsibilities

• Own application and infrastructure security across our AWS environment — threat-modeling new systems, reviewing designs and code, and fixing the issues you find.
• Own identity and access — from least-privilege IAM to how engineers and AI agents get scoped, auditable access to production.
• Set the security baseline for the whole engineering org, turning one-off fixes into durable controls that make the secure path the default.
• Build security into how we ship, partnering with the platform team on CI/CD and developer tooling.
• Shape how AI coding agents operate safely against real systems.
• Partner closely with Adyen's security organization, bringing their scale and practices to bear as we grow.

Requirements

• 5+ years of experience in software or security engineering.
• Strong hands-on background securing cloud-native systems (AWS preferred), comfortable reading and writing code.
• Depth across several of: application and product security, IAM and access management, vulnerability management, detection and response.
• Default to solving security problems structurally — making the safe path the default rather than adding process.
• Comfortable being the first dedicated security hire, operating with a lot of autonomy.

Nice-to-Haves

• Experience with AI coding agents and their security implications.

• Excellent medical, dental, and vision insurance.
• One Medical membership.

• 401k plan.
