You’ll be a key engineer responsible for designing, evolving and operating our Web Application Firewall (WAF) platforms, protecting critical customer‑facing services at scale.
You’ll work with modern engineering practices including automation, and secure‑by‑default design to improve resilience, performance and security across our edge, datacentre and cloud environments.
Engineering new WAF capabilities using Infrastructure‑as‑Code, CI/CD pipelines and policy‑as‑code approaches to deliver secure, repeatable and scalable outcomes
Playing a key role in platform modernisation and service improvements, including refactoring, automation and the reduction of technical debt
Driving observability and operational insight by improving monitoring, alerting and telemetry to strengthen platform reliability and incident response
Supporting major incident diagnostics, partnering closely with Security Engineering, Networks and Cloud teams
Producing high‑quality engineering documentation, including standards, patterns, platform guidance and runbooks that enable self‑service and repeatability
Participating in the on‑call rota, contributing to the operational resilience of critical services (with additional compensation)

A proven engineering mentality, with hands‑on experience across edge, on‑prem and cloud‑native WAF technologies
Strong automation and scripting skills (Python preferred), with practical experience using Infrastructure‑as‑Code tools (Terraform preferred) and modern CI/CD pipelines
Solid understanding of networking and web fundamentals, including HTTP/S, DNS, TLS and platform security concepts
Ability to lead complex technical investigations, diagnose issues under pressure and guide others toward robust solutions
Confidence to influence engineering decisions and contribute to strategic technical direction
Knowledge of Application Security, API Security, Bot Protection and Layer 7 DDoS
Professional‑level cloud certifications and/or recognised security or network engineering accreditations
