About the role
As Lead Security Engineer, you'll own application security across our platform, embedding secure practices into how we design, build, and ship software, and setting the direction for a growing security function.
What you'll do
- Own the application security program end to end: threat modelling, secure design reviews, code review, and vulnerability management.
- Build security into the SDLC with SAST, DAST, dependency/SCA, and secrets scanning integrated into CI/CD without slowing teams down.
- Partner with engineering on authentication, authorization, multi-tenancy isolation, and data protection across our APIs and SDKs.
- Lead penetration testing, bug bounty triage, and incident response for application-layer issues.
- Support customer security reviews and compliance (SOC 2, HIPAA, GDPR) with practical technical controls.
- Mentor engineers and raise the security bar across the organisation.
What we're looking for
- 7+ years in software or security engineering, with significant hands-on AppSec experience.
- Strong coding ability (Python and/or TypeScript ideal) and the credibility to review and fix code, not just flag issues.
- Deep knowledge of web and API security (OWASP Top 10, OAuth/OIDC, authz models, SSRF, injection, deserialisation).
- Experience securing cloud-native SaaS (GCP or AWS, Kubernetes, containers).
- Track record of building security tooling and processes in a fast-moving product company.
- Clear communicator who can influence engineering teams and speak to enterprise customers.
Nice to have
- Experience with ML/AI systems security (data pipelines, model supply chain, LLM-specific risks such as prompt injection).
- Background in regulated industries such as healthcare.
- Previous experience as an early or first dedicated security hire.
Why Encord
- Competitive salary, and meaningful equity in a high-growth startup
- Strong in-person culture — most of the team works from our London office 4+ days/week
- 25 days annual leave + UK public holidays
- Annual learning & development budget
- Travel for customer visits, events, and conferences across the UK and Europe
- Daily company lunches
- Monthly socials & bi-annual team offsites
