About the Role: Senior Network Engineer

The Team: Global Network Services is seeking a Senior Network Engineer to join our dynamic, multi-disciplinary team. You will design, automate, and operate the DNS, edge delivery, and application delivery services that keep S&P; Global's platforms quick, secure, and available. We value continuous learning, excellence, and a proactive mindset.

Responsibilities and Impact

DDI, Edge Security, and Application Delivery

- Own the architecture and operation of enterprise DDI services, including Infoblox (DNS, DHCP, IPAM) and cloud DNS (AWS Route 53, Azure DNS/Private DNS, Google Cloud DNS), with hybrid DNS resolution across on-premises and multi-cloud environments.
- Integrate IPAM/DDI with the CMDB to keep IP, host, and network records accurate and in sync, using discovery data and API-driven reconciliation to detect and correct drift.
- Design and operate DNS security controls, including DNSSEC, DNS firewall (e.g., Infoblox BloxOne Threat Defense), protection against DNS attacks
- Design and manage CDN, WAF, bot management, and DDoS protection using Akamai and Cloudflare, including rule tuning, policy management, and traffic analysis.
- Design and operate load balancing and traffic management, including F5, cloud-native load balancers (AWS ELB/ALB, Azure Application Gateway, GCP Load Balancing), and global server load balancing.

Automation and Infrastructure as Code

- Write,



test, and maintain Terraform modules to provision DNS, edge, and load balancing services across AWS, Azure, and GCP, setting shared-module patterns.
- Build Python tooling and API integrations (e.g., Infoblox WAPI, Akamai ,Cloudflare APIs) to remove repetitive manual tasks and improve consistency.
- Build and improve CI/CD pipelines for changes, including automated validation, pre-deployment testing, and policy checks.
- Develop automated configuration and compliance checks to catch deviations from approved standards (e.g., DNS records, WAF policies, IPAM allocations) early.
- Follow good engineering practice in shared repositories: version control, peer review, modular code, and clear documentation.

Collaboration and Continuous Improvement

- Serve as subject matter expert and third-line escalation point for complex incidents, leading root cause analysis.
- Collaborate with application, product, engineering, and security teams to deliver changes meeting enterprise standards and compliance requirements.
- Plan and execute approved changes within agreed maintenance windows, with documented back-out steps, and join out-of-hours change windows as required.
- Produce and maintain architecture documentation, automation runbooks,



and standard operating procedures.
- Mentor engineers, share knowledge, and identify ways to reduce risk, improve efficiency, and raise standards.
