Skills & requirements

Qualification

You're a Security Engineer first, who has grown into leadership. You're comfortable in the details and know when to roll up your sleeves, but you've also developed the organisational instincts to run a team effectively and the strategic clarity to own a function. You're a strong communicator who can operate across audiences — from deeply technical discussions with staff engineers, to clear risk framing for leadership, to pragmatic negotiation with product and engineering partners. You have a strong engineering background in application security, with hands-on experience in areas such as threat modelling, secure design review, (AI-)SAST/SCA tooling, vulnerability management, and/or security automation.

You've led or significantly contributed to an AppSec programme in a fast-growing SaaS or AI company, ideally one where the engineerin
