If you've worked in a comparable MSP tool stack, you're a strong fit. In general, our environment includes: * Windows Server and Windows desktop environments across a range of client sizes, on enterprise-class server and workstation hardware * Microsoft 365 / cloud productivity (Exchange Online, SharePoint, OneDrive, Teams) * Enterprise network equipment including routers, switches, firewalls, and wireless access points from HP, Ubiquiti, Meraki, and SonicWall * Endpoint detection and response (EDR) / endpoint security platforms * Email security and anti-phishing filtering * VoIP / cloud phone systems * PSA/RMM and remote support tooling * A dedicated documentation platform ## Description This isn't a typical Level 3 ticket queue position. You'll be one of our final points of technical escalation, leading complex network and infrastructure projects from assessment through completion. We've been in business for 23 years. Our clients typically range from 10-100 users, and we standardize environments using mainstream, best-practice solutions to ensure predictable, secure, and reliable networks. Location & Schedule * Full-time, Monday-Friday, 8:00 AM - 5:00 PM * Participate in the after-hours on-call rotation: one week of nights and weekends coverage approximately once every 6 weeks. We generally get less than 5 calls a week. * Based in the Chicagoland area, with the ability to travel to client sites as needed * This is a field-based role. We have no central office, so time not spent at client sites is worked from your own home base in the Chicagoland area * Some engagements may require being on-site at a single customer location for a full work week at a time (e.g., project cutovers, migrations, on-site assessments, or emergency response) * Project work will occasionally fall on evenings or weekends (not every week, but candidates must be willing and able to work outside standard hours when a project or emergency requires it) * Valid driver's license and reliable transportation required What You'll Do * Serve as one of the final points of technical escalation for complex, hard-to-diagnose issues * Design, plan, and lead networking and infrastructure projects including segmentation, routing, switching, and firewall/network assessments and building the project plan directly with the client * Run client-facing infrastructure assessments and translate findings into a scoped project plan * Support multiple client environments and switch contexts efficiently * No task is "below" this role. You must be comfortable picking up a Level 1 or Level 2 ticket when the team needs it * Mentor and provide technical guidance to other engineers, serving as one of the team's go-to resources for complex issues * Assist with client onboarding and infrastructure projects * Own the rollout of new endpoint and network deployments across client environments, and periodically audit them to catch and close coverage gaps such as missing or offline agents, unpatched devices, and misconfigured network equipment * Own and maintain technical documentation and SOPs in our documentation platform (documentation-first mindset required) * Meet directly with vendors when their product support is needed during a project * Provide on-site consulting, project leadership, emergency response, and hardware support as needed, including extended on-site stays at customer locations when a project calls for it
