Application Security Engineer
Genomics, London +1
Overview
Location: Oxford or London (Hybrid)
What you need
- Experience within application security in production. You've found and fixed exploitable bugs in software you were responsible for, through threat modelling, secure design, code review, and proof-of-concept exploitation across web services, APIs, and data-serving interfaces. Triaging scanner output doesn't count
- Production-quality software engineering in at least one mainstream language (such as Python, Go, or TypeScript), and you can read several. You've built and operated security or developer tooling in CI/CD pipelines, such as static and dependency analysis, secrets detection, or policy-as-code, and engineers actually adopted it
- Hands-on depth securing multi-tenant systems on a major cloud. We run on AWS (RDS, EC2, S3, EKS, Batch), and comparable GCP or Azure depth transfers. You know tenant isolation, IAM and least privilege, secrets management, Kubernetes and container security, and the trust boundaries between services
- Daily use of frontier AI models for code analysis, vulnerability triage, remediation drafting, and research, with sharp judgement about where they're reliable and where they mislead. You've built or tuned LLM-driven tooling rather than only used a chat interface, and you understand the attack surface it introduces
