Senior Security Engineer- San Francisco HQ

Orb•San Francisco, CA

4d•$195,000 - $265,000•Hybrid

About The Position

As Orb's first dedicated Security Engineer, you will own the hands-on technical security of a platform trusted with our customers' most sensitive data — their revenue. Billing sits at the center of how our customers run their businesses, and as we've grown (and as we lean heavily into AI-assisted development), securing our infrastructure, our code, and the way we ship has become a full-time job of its own. You'll make the secure path the default across our AWS environment and our codebase, working directly with our engineering lead and partnering closely with Adyen's security organization.

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
You 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

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 — one of the more interesting security problems we have
Partner closely with Adyen's security organization, bringing their scale and practices to bear as we grow
