Senior Full Stack Java Developer Jobs in Illiopolis, IL

Job Title: Senior Network Infrastructure Architect (SASE & SD-WAN)
Role Overview
We are seeking a Senior Network Infrastructure Architect to lead the transformation of our enterprise networking environment. This is a hands-on, high-impact role for an engineer who is ready to move beyond traditional hardware-centric networking and into the world of Software-Defined Networking (SDN), Secure Access Service Edge (SASE), and Zero Trust Network Access (ZTNA).
You will own the lifecycle of our next-generation network strategy-from developing roadmaps and low-level engineering designs to providing Tier-3 subject matter expertise for our most complex production incidents. The ideal candidate is a collaborative "bridge builder" who can design secure, holistic solutions that integrate Cloud (Azure), LAN, WAN, and Wireless environments into a single, automated fabric.
Key Responsibilities
Strategy, Design & Automation
• Next-Gen Architecture: Architect and design advanced network solutions that support the transition to SASE and ZTNA frameworks. Proactively propose new standards that ensure our environment remains performant and secure.
• Network Automation: Spearhead the development of an SDN model across Cloud, LAN, WAN, and Wireless platforms. Integrate automation technologies with our observability stack to drive "AIOps" and proactive network management.
• Security-by-Design: Ensure security requirements (encryption, micro-segmentation, policy enforcement) are baked into the architecture, not bolted on.
• Roadmap Development: Partner with cross-functional architecture teams to build long-term technology roadmaps. Develop build instructions and implementation plans that the operations teams can execute with precision.
Operational Leadership & SME Support
• Tier-3 Escalation: Act as a final point of escalation for complex P1/P2 incidents. Lead root-cause analysis (RCA) efforts and design systemic action plans to prevent recurrence.
• Collaboration: Provide "subject matter expert" support to operations teams, acting as a coach and mentor while maintaining a strong pulse on current operational health and technical blockers.
• Vendor & Standards Stewardship: Liaise with 3rd-party vendors to evaluate new technologies and review change requests from peer teams to ensure they align with our "holistic solution" design philosophy.
Qualifications & Requirements
Minimum Qualifications
• Experience Baseline: Extensive experience implementing and developing vendor-agnostic Software-Defined Networking (SDN) platforms and network automation.
• Core Competencies: Deep, demonstrable experience in:
oSASE (Secure Access Service Edge) and ZTNA (Zero Trust Network Access) architectures.
oCloud-Native Networking: Specifically Azure networking.
oEnterprise Hardware: Advanced Cisco routing, switching, and Palo Alto firewall management.
• Technical Mastery: In-depth knowledge of L2/L3 connectivity, BGP, OSPF, IS-IS, VPN (IPSec/SSL/TLS), and DNS/DHCP.
• Certification: CCNP (Cisco Certified Network Professional) or equivalent level of professional certification.
Preferred Attributes
• Proven experience developing technology roadmaps based on strategic business inputs.
• Ability to translate high-level requirements into low-level engineering designs using Visio.
• Experience integrating network automation with modern monitoring and observability toolsets (e.g., AIOps-based solutions).
• Strong "bridge-building" soft skills-you must be comfortable working with cross-functional teams to drive holistic change rather than working in a silo.
