How we work at Aircall: We’re customer-obsessed, data-driven, and focused on delivering meaningful outcomes. We value ownership, continuous learning, and thoughtful speed. If you thrive in a collaborative, fast-moving environment where trust and impact matter, you’ll feel at home here. As a Security Engineer, Product Security, you will help Aircall build and ship secure products by working closely with engineering teams and product managers to identify risk early, reduce vulnerabilities, and improve security quality across the software development lifecycle. You’ll support secure-by-design practices and help ensure security is integrated into how teams design, build, test, and release software. In this role, you’ll be hands-on across threat modelling, vulnerability detection and remediation, and security testing. You will partner with engineers to make security practical and actionable — helping teams move quickly while raising the security bar. You'll also have a strong bias to leveraging AI to scale.
