As our first Head of Security, you'll own security across the company: product, infrastructure, corporate, and compliance. You'll set the strategy, build the team, and grow into the CISO role as we scale. What you'll do Own the security strategy and roadmap across application, cloud, corporate, and AI security. Build and lead the security team, hiring across AppSec, cloud, and GRC as we grow. Embed secure-by-design practices into engineering, covering threat modelling, the secure SDLC, and pentest and bug bounty programs. Own ISO 27001, SOC 2, and emerging AI standards such as ISO 42001, plus GDPR and HIPAA readiness for healthcare customers. Act as the security voice to enterprise customers: due diligence, executive briefings, and contractual security terms. Lead incident response and report security risk to the exec team and board. Set guardrails for how Encord builds with and adopts AI, including LLM risks, data handling, and vendor reviews. What we're looking for 10+ years in security, including 3+ years owning or leading the security function at a high-growth tech or SaaS company. Strong technical depth in at least one of AppSec or cloud security (GCP ideal), with enough breadth to lead across all domains. A track record of delivering ISO 27001 and/or SOC 2 as the accountable owner. Experience building and managing security teams from early stage. Credibility with engineers, enterprise customers, and the board, with a pragmatic approach that enables speed rather than blocking it. Nice to have Experience securing ML/AI platforms or data-intensive products. Experience in regulated sectors such as healthcare, life sciences, or automotive.
