What you'll be doing…
You'll be a key engineer responsible for designing, implementing, evolving and maintaining our Web Application Firewall (WAF) platforms, protecting critical customer-facing services at scale.
You'll use modern engineering practices, including automation and secure-by-default design, to improve the resilience, performance and security of our edge, data centre and cloud environments. The role offers real scope to influence technical direction, raise engineering standards, and develop our WAF and wider Layer 7 security services.
Day to day, you'll work with a high degree of autonomy and contribute technical influence across the team. Your responsibilities will include:
- Design, implement and continuously optimise WAF security controls, developing and tuning rules and policies to improve protection against emerging threats while minimising false positives and maintaining a seamless customer experience.
- Engineer 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.
- Support the diagnosis and resolution of major incidents, partnering closely with Security Engineering, Network and Cloud teams.
- Embed secure-by-design patterns and guardrails, ensuring controls are codified, consistent and easy for platform consumers to adopt.
- Produce high-quality engineering documentation, including standards, patterns, platform guidance and runbooks, to enable self-service and repeatable delivery.
- Participate in the on-call rota, helping to maintain the operational resilience of critical services, with additional compensation provided.
