You will design, automate, and operate DNS, edge delivery, and application delivery services that keep S&P Global's platforms fast, secure, and available. ## 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. ## What We're Looking For ### Basic Required Qualifications - 5+ years' experience in network or infrastructure engineering supporting hybrid, multi-cloud environments. - Extensive hands-on experience with Infoblox DDI, including DNS architecture, DHCP, and IPAM design and operations. - Hands-on experience with DNS in Infoblox and at least two cloud DNS providers: AWS Route 53, Azure DNS, Google Cloud DNS. - Strong experience with Akamai and/or Cloudflare, including CDN, WAF, bot mitigation, and DDoS protection. - Hands-on experience with load balancers (e.g., F5, NGINX, AWS ELB/ALB, Akamai GTM). - Strong experience with Terraform and Infrastructure as Code, including module design and Git-based version control. - Proficiency in Python for automation and API integration, following software development best practices (testing, code review). - Solid understanding of core networking, DNS, and HTTP protocols, able to read configuration as code and assess a change's impact before deploying it. - Strong troubleshooting and analytical skills, with attention to detail. - Ability to manage multiple projects and priorities simultaneously. - Excellent written and verbal communication skills, and the ability to work effectively in a cross-functional team. ### Additional Preferred Qualifications - Experience querying observability and logging platforms (e.g., Splunk, Grafana, Google Secops etc) to analyze DNS, CDN/WAF, and load balancer telemetry, build dashboards and alerts, and troubleshoot incidents. - Experience building AI-assisted automation, such as agents that call Infoblox, Akamai, Cloudflare, or cloud APIs (e.g., via MCP servers). - Experience integrating IPAM/DDI with a CMDB or ITSM platform including discovery-based synchronization and automated request workflows. - Experience with low-code automation platforms. - Active Directory infrastructure knowledge. - Experience in a regulated environment with formal change and audit requirements. - AI fundamentals. - Relevant certifications, such as Infoblox DDI Professional, Terraform Associate, Akamai or Cloudflare certifications, or AWS, Azure, or GCP networking certifications. ## Benefits - Health & Wellness: Health care coverage designed for the mind and body. - Flexible Downtime: Generous time off helps keep you energized for your time on. - Continuous Learning: Access a wealth of resources to grow your career and learn valuable new skills. -
