Monitor for system vulnerabilities and suspicious activity.
Coordinate with outside cybersecurity or specialty vendors as needed.

Vendor & Technology Management

Manage relationships with outside technology vendors, internet providers, phone systems, and specialty IT consultants.
Maintain productive working relationships with external IT and cybersecurity partners to support escalated issues, specialized expertise, and business continuity needs.
Serve as primary liaison for escalated issues requiring external support.
Evaluate and recommend technology improvements that support business growth and efficiency.
Maintain software licensing and technology-related contracts.

Business Systems Support

Support business-critical software platforms used by Jennings Mechanical, including accounting, project management, estimating, payroll, and operational systems.
Partner with leadership and department managers to improve workflows and identify technology solutions.
Assist with reporting, integrations, and system optimization.

Strategic IT Planning
