Senior Security Engineer
First dedicated Security Engineer owning application, infrastructure, and identity security for Orb's AWS-based revenue platform. Requires 5+ years in security or software engineering with depth in cloud security, IAM, and structural controls; partners with Adyen's security team.
About the job
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.
Compensation and Benefits
- Excellent medical, dental, and vision insurance.
- One Medical membership.
- Unlimited PTO plus an additional week off between Christmas and New Year’s.
- 401k plan.
- 16-week paid parental leave with equity vesting.
- Commuter stipend.
- Catered lunches in the office.
- Annual learning & development stipend.
- Meaningful equity in the form of stock options.
