## About the Role

* Application security experience: You have at least five years of experience in application or product security, or in engineering with a security focus, ideally in SaaS, startups or scaleups across different tech stacks and cloud platforms.
 * Fixes, not just findings: You have a track record of driving security issues from discovery to a verified fix, and you work with engineers to find a workable path instead of blocking their releases.
 * Code and automation: You read code across different tech stacks and write scripts and automation, for example in Python or Go or JavaScript.
 * Security tooling: You are hands on with SAST, DAST, SCA and CI/CD pipeline security.
 * Clear risk communication: You prioritise clearly, explain risk in plain language and take ownership of your topics with minimal supervision.
 * AI-assisted security work: You build AI harnesses and agents that support security work such as vulnerability triage, scanning and analysis of indicators of compromise.
 * Fluent English: You are fluent in English, which you use daily to work with engineering teams and the CISO.
 * Nice to have: Cloud security experience on sovereign cloud, penetration testing experience or a certification such as OSCP or OSWE, and an understanding of the security of AI and LLM features.

## Description

Seven Education runs seven products on different tech stacks, and none of them has dedicated application security capacity today. As our (Senior) Application Security Engineer, you turn security findings into fixes and set one security baseline across all products. You report directly to our CISO and work closely with the engineering teams who build and run our platform. Schools trust us with the data of children and teachers, and you make sure that trust holds as our products and AI features grow.
What you'll do

 * Vulnerability management: You run vulnerability management across our seven product estates. You tune the scanners, agree fix deadlines with Engineering, retest once fixes have landed and report on progress.
 * Cutting through the noise: You turn a large and growing volume of scanner findings from different tech stacks into a short list of real, exploitable issues that teams actually fix.
 * Penetration test triage: You triage penetration test results together with the CISO, assess severity and priority, pass findings on to Engineering and retest once fixes have landed.
 * Audit evidence: You build automations that collect security evidence for our various audits and keep them running.
 * Pipeline security: You define and tune the security checks in our CI/CD pipelines, including secrets detection, DAST, fuzzing and the SBOM checks that matter for our products.
 * Design and feature reviews: You review new features and designs against one group baseline and keep data flow diagrams and the security architecture up to date.
 * Security alerting: You support the CISO in building security alerting, so that we can see security events across our IT systems.
 * Production access model: You design the production access model with Engineering and IT and start its rollout.
