The Position:
Chameleon Integrated Services is currently looking for a Senior Network Engineer to support one of our local clients in St. Louis city.
Overview:
We are seeking a Senior Network Engineer Consultant to provide near-term support following the departure of key networking personnel, including the senior network engineer and day-to-day network manager. The consultant will assess the current network environment, evaluate operational readiness and security posture, improve and/or create missing documentation, and develop a practical roadmap for improvements and modernization.
This engagement may begin as a part-time consulting assignment and may expand in scope and duration depending on the individual’s performance, the client's needs, and the recommendations produced during the assessment.
Responsibilities:
Phase 1 – Discovery & Assessment (Initial 2–4 weeks)
The consultant will perform discovery, interviews, and technical validation to establish a clear understanding of the City’s current networking environment.
Activities may include:
- Stakeholder interviews (IT leadership, security team, help desk, application owners, vendors)
- Review of existing network diagrams, inventories, contracts, and monitoring tools
- Assessment of network core/distribution/access architecture and WAN connectivity
- Review of routing, switching, VLANs, and IP addressing strategy
- Firewall posture review (rulebase structure, segmentation approach, remote access/VPN)
- Wireless architecture review (coverage, authentication, controller configuration, guest access)
- Review of monitoring, alerting, and network performance visibility
- Review of configuration backup methods and change control practices
- Identification of single points of failure and operational “tribal knowledge” dependencies
- Current-State Assessment Summary (strengths, gaps, immediate risks)
- Initial Findings Briefing to IT leadership
- Prioritized “Quick Wins” list (30-day action items)
The consultant will build or improve documentation to ensure the City can run and support the network with fewer single-person dependencies.
Documentation deliverables may include:
- High-level network topology diagram(s)
- Site connectivity / WAN overview diagram(s)
- VLAN / subnet / IP schema documentation
- Firewall and segmentation overview (including remote access model)
- Wireless overview (SSIDs, authentication, access policies)
- Hardware inventory (switches, routers, firewalls, controllers) including OS/firmware versions where available
- Circuit inventory (provider, bandwidth, purpose, cost if available, renewal dates)
- Network administration runbook (standard tasks, access procedures, escalation procedures)
- Recommended folder structure and standards for ongoing documentation maintenance
- Phase 3 – Recommendations & Roadmap (Weeks 5–8)
Deliverables (Phase 3):
- Prioritized Recommendations Matrix (by risk reduction, cost, complexity, effort)
- 12–24 Month Network Roadmap including sequencing and dependencies
- Modernization guidance (architecture direction, lifecycle replacement, monitoring improvements)
- Budgetary ROM estimates where possible (not formal quotes)
- Leadership Readout (slide deck or summary presentation)
Based on findings and City priorities, the consultant may continue in a part-time or expanded role to execute improvements, provide operational continuity, support vendor engagements, and help transition to permanent staffing.
Examples of ongoing tasks:
- Implementing approved network improvements and remediation actions
- Assisting with firewall policy clean-up and segmentation enhancements
- Supporting wireless improvements and network performance tuning
- Participating in change management meetings and advising leadership
- Vendor coordination and technical evaluation support
- Mentoring junior staff or assisting with onboarding a replacement network manager

- Proven expertise with:
- Routing and switching (enterprise networks)
- Firewall administration and policy design
- Network segmentation best practices
- WAN connectivity and site-to-site connectivity
- Wireless networking in enterprise environments
- Strong documentation discipline (diagrams, inventories, runbooks)
- Experience assessing environments with limited documentation and stabilizing operations
- Ability to communicate clearly with both technical staff and leadership
- Comfortable operating independently and driving work with minimal oversight
Preferred Experience

- Exposure to Zero Trust or identity-based network access concepts
- Experience with any of the following (depending on City stack):
