We’re a leading global online delivery platform, and our vision is to empower everyday convenience.\nWhether it’s a Friday-night feast, a post-gym poke bowl, or grabbing some groceries, our tech platform connects tens of millions of customers with hundreds of thousands of restaurant, grocery and convenience partners across the globe.\nAbout this role\nJET's Information Security organisation protects a technology-led, cloud-native platform serving millions of customers across multiple markets. JET's building security into the foundations of how we design, engineer, and operate our cloud-native platforms at scale, across our technology organisation.\nJET'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.\nThese are some of the key components to the position:\nDesign, build and deploy security controls and guardrails across JET's cloud-native platforms, including AI security solutions protecting customer-facing products.\n\nRun password audits, network and web application vulnerability scans, and intrusion detection to identify and close gaps before they're exploited.\n\nAutomate security processes as code, embedding compliance and IaC checks into CI/CD pipelines shipping over 100 times daily.\n\nConduct risk audits and assessments, translating findings into practical recommendations for engineering teams.\n\nMonitor and analyse system access logs, flagging anomalies and supporting incident response.\n\nPlan and test security backup and disaster recovery processes to keep JET's platforms resilient.\n\nPartner with 1st and 2nd line InfoSec teams as customers of your solutions, translating technical work for product and engineering audiences.\n\nWhat will you bring to the team?\nPractical experience writing and deploying applications or tooling into cloud-native environments (AWS, Azure or GCP).\n\nStrong, demonstrable skills deploying AI security solutions, guardrails, and defences for AI systems used by customers.\n\nProficiency in at least one of C#, Python, Java, PowerShell or Bash, with a track record of automating security processes.\n\nWorking knowledge of Infrastructure as Code and Compliance as Code practices.\n\nComfort operating in Agile, DevOps-driven teams with frequent, continuous delivery.\n\nConfident stakeholder management, translating security risk and technical decisions into language product and engineering teams act on.\n\nA collaborative, evangelist mindset, building trust so others choose secure defaults rather than having security imposed on them.\n\nAt JET, this is how we play\nOur teams forge connections internally and work with some of the best-known brands on the planet, giving us truly international impact in a dynamic environment. \nBeing the best at what we do isn’t just about delivering on our strategy. It's a competition for something incredibly valuable - our customers' choice. Every time a customer decides where to order, they're picking a side.\nAt the heart of the JET Customer League are our values and behaviours. They guide every interaction, every decision, every innovation. These are the actions we need to perform consistently and brilliantly, to surpass the competition and earn our customers’ loyalty, again and again.\nFun, fast-paced and supportive, the JET culture is about movement, growth, helping one another to succeed and celebrating wins. By truly living our values and embodying our behaviours, we’re building a customer-first culture which enables us to stay one step ahead of the competition.\nInclusion, Diversity & Belonging\nNo matter who you are, what you look like, who you love, or where you are from, you can find your place at Just Eat Takeaway.com.
