- Implement and tune advanced features such as GSLB, HA, responder/rewrite policies, caching, compression, and rate limiting; integrate with authentication and SSO (LDAP/AD, SAML, OAuth).
- Monitor and troubleshoot performance using platform analytics (e.g., AppFlow/HDX Insight), logs, and external APM/NPM tools; drive root cause analysis for incidents.
- Develop and maintain network and application delivery automation using Python and Ansible; leverage REST APIs/CLI, version-controlled templates, and CI/CD pipelines for repeatable deployments.
- Ensure engineering patterns meet SLA/availability, performance, and resiliency requirements; contribute to capacity planning and lifecycle refresh.
- Write and review change requests and methods of procedure (MoPs); conduct impact analysis, staged testing, and post-implementation verification.
- Produce and maintain documentation (network and ADC diagrams, standards, inventories, runbooks) and leverage monitoring/resource management tools.
- Collaborate with application, security, and cross-functional teams to plan changes, enforce standards, and execute releases with low risk.
- Participate in an on-call rotation to ensure 24x7x365 coverage for critical infrastructure; overtime may be required during emergencies.
