## Description

JET's Security Engineering team builds the tools, guardrails and controls that let every engineer at JET ship secure code, over 100 times a day. As a Senior Security Engineer, you'll design, build and run the security solutions our 1st and 2nd line InfoSec teams and wider engineering community rely on daily, from vulnerability scanning and access monitoring to AI security guardrails. You'll work hands-on within JET's global Security Engineering team, turning security policy into code and every engineer into a security-conscious one.

 * Design, build and deploy security controls and guardrails across JET's cloud-native platforms, including AI security solutions protecting customer-facing products.
 * Run password audits, network and web application vulnerability scans, and intrusion detection to identify and close gaps before they're exploited.
 * Automate security processes as code, embedding compliance and IaC checks into CI/CD pipelines shipping over 100 times daily.
 * Conduct risk audits and assessments, translating findings into practical recommendations for engineering teams.
 * Monitor and analyse system access logs, flagging anomalies and supporting incident response.
 * Plan and test security backup and disaster recovery processes to keep JET's platforms resilient.
 * Partner with 1st and 2nd line InfoSec teams as customers of your solutions, translating technical work for product and engineering audiences.
