• Auditing functions: provider set up in Orinoco (demographic and fee schedules), online search tool, print directory, Periscope reports, claims payment. • Determine root cause of issues and recommend process improvements. • Provide clear analysis and next steps for network team. • Analysis of network grievances, determination of track and trend or provider outreach, complete outreach as needed, prepare monthly reporting. • Contracting to support network adequacy in existing and expansion counties. • Contract processing, to include: obtaining contract signatures, preparing provider rosters, submitting contract load form. • Assistance with Field Network cases, outreach to providers, documentation of resolution. • Evaluate participation requests against network need, current contractual relationships, expansion efforts, access to care. • Make recommendations to management. • Contract as needed. • Respond accordingly to providers. • Assist network managers with monthly JOC meeting preparations, research outliers in financial reports, audit reports for accuracy, assist with follow up items from meetings.

• Monitoring certificate expiration alerts and proactively engaging application teams • Issuing, renewing, and validating certificates (internal and external) • Troubleshooting SSL/TLS handshake failures, certificate chain issues, or trust errors • Reviewing CSRs for accuracy (SANs, key sizes, usage types, etc.) • Validating successful certificate binding post-change (browser, OpenSSL, CLI validation) • Investigating certificate-related incidents or production escalations • Installing and binding certificates to NetScaler virtual servers (VLSB) • Managing GSLB configurations and SSL profiles • Updating SNIPs, VIPs, service groups, and monitors as needed • Supporting load balancer changes during maintenance windows • Troubleshooting Layer 4–7 connectivity or persistence issues • Participating in change management and validation processes • Running reports or dashboards on expiring certificates and compliance posture • Partnering with application teams to improve certificate hygiene and ownership • Documenting repeatable procedures and improving runbooks • Identifying automation opportunities to reduce manual certificate work • Acting as an escalation point for complex SSL or load balancing issues • Advising teams on certificate standards, cipher policies, and secure configurations

• Design and implement advanced BGP policies (path selection, community strings, filtering) to optimize multihoming and peering traffic across multiple IXPs. • Design, configure, and maintain the MPLS core, including LDP and RSVP-TE, and implement L3 VPN services (VRFs) and L2VPNs (VPLS/VPWS) for enterprise customers. • Perform Traffic Engineering (TE) using RSVP-TE to ensure deterministic paths and apply QoS policies (DiffServ over MPLS) to prioritize critical services (voice and video). • Implement high-availability and fast-convergence mechanisms such as BFD (Bidirectional Forwarding Detection) and MPLS FRR (Fast Reroute), targeting maximum SLA (five nines, 99.999%). • Manage edge routers (Provider Edge - PE) and Carrier-Grade NAT (CGN) solutions, and design the transition to IPv6 (Dual Stack or DS-Lite). • Lead the resolution of complex incidents involving packet loss, microbursts, high latency, and protocol failures (BGP session flapping, OSPF/IS-IS adjacency issues).

• Support add/move/change (MAC) activities across production financial-markets networks • Configure and troubleshoot Layer‑2 and Layer‑3 network services • Assist with BGP, OSPF, and IS‑IS routing changes and troubleshooting • Support NAT configuration and fault isolation (static and dynamic NAT) • Assist with IP multicast (IGMP, PIM) used for market data distribution • Perform packet capture and traffic analysis (tcpdump, Wireshark or equivalent) • Assist with Layer‑1 troubleshooting including physical connectivity and latency-sensitive paths • Follow disciplined change, documentation, and operational processes • Work with senior engineers on automation-enabled configuration and validation
