Senior Infrastructure & Network Engineer (L3) (Part-time)Architecture, Security & CompliancePosition Summary
We are seeking a highly experienced Senior Infrastructure & Network Engineer (Level 3) to provide senior-level technical oversight, architecture review, configuration validation, project assurance, and infrastructure compliance support across our enterprise technology environment.
This is not a traditional network administration or deployment-focused position.
The primary purpose of this role is to serve as a senior technical reviewer and trusted second set of eyes for infrastructure and network projects. The engineer will review proposed architectures and implementations, identify technical or security weaknesses, recommend improvements, assist with complex configuration adjustments when necessary, and independently verify that systems have been implemented correctly.
The engineer will work closely with IT leadership, infrastructure teams, vendors, MSPs, and the cybersecurity team to ensure that technology implementations are reliable, scalable, secure, properly documented, and aligned with established cybersecurity and compliance requirements.
The role will also participate in the development of automation and AI-assisted compliance validation, including an AI CISO platform designed to continuously review technical controls, configurations, asset coverage, and compliance evidence.
Core Responsibilities
- Review network and infrastructure architectures before implementation.
- Review configurations implemented by internal teams, vendors, MSPs, and other technical resources.
- Validate that infrastructure projects follow technical, security, and vendor best practices.
- Identify design weaknesses, configuration problems, unnecessary exposure, and operational risks.
- Provide recommendations for improving architecture, reliability, performance, security, and maintainability.
- Perform post-implementation reviews to verify systems were configured as designed.
- Assist engineers with complex configuration changes and troubleshooting when senior-level expertise is required.
- Independently validate remediation after identified issues have been corrected.
- Participate in technical design and architecture discussions for new projects.
- Review implementation plans, change plans, testing procedures, and rollback strategies.
- Maintain and improve technical standards, configuration baselines, and review checklists.
