Job description

At Sigma Information Group, we don’t just solve IT problems—we partner with clients to elevate their entire tech ecosystem. As a Systems Engineer Consultant you’ll serve as the trusted technical advisor to a diverse range of small and mid-sized businesses, taking ownership of their infrastructure and delivering expert-level service across systems, networks, and cloud platforms.

If you thrive on variety, value autonomy, and love turning complex technical challenges into clean, strategic solutions—this role is for you.

What You’ll Do

• Serve as the primary technical lead for multiple client environments, maintaining servers, networks, desktops, security tools, and cloud platforms.
• Build trusted relationships with clients and act as their go-to advisor for IT strategy, planning, and issue resolution.
• Architect and implement infrastructure upgrades, network deployments, and cloud migrations.
• Lead and manage projects—coordinating timelines, resources, vendors, and deliverables.
• Run status meetings with clients and internal teams to track milestones and maintain transparency.
• Solve a wide range of issues—from everyday support tickets to critical outages and high-level architecture decisions.
• Roll up your sleeves for hands-on work including hardware installs, firewalls, backups, patching, and performance tuning.

What You Bring

• 3 - 5 years of experience in IT consulting, MSP support, or system/network administration
• Working knowledge of business IT environments, including:
• Windows Server, Active Directory, Group Policy, DNS/DHCP
• Virtualization tools (VMware, Hyper-V), Remote Desktop Services
• Firewalls and networking (Fortinet, Palo Alto, routing, VPNs)
• Backup, security, and disaster recovery solutions
• Microsoft Azure or AWS cloud platforms
• Excellent verbal and written communication skills
• Physically able to handle computer hardware as needed
• Based in Austin or nearby, with reliable transportation for client visits

What Makes a Great Sigma Consultant

• Technologically curious and always learning
• Adaptable—can shift between client sites, project work, and emergency triage
• A confident communicator who can explain complex topics to non-technical audiences
• Calm under pressure and professional with executive stakeholders
• Comfortable working independently while staying aligned with the broader teams
