About it / systems admin roles
IT and systems admin roles keep the company's hardware, networks, and accounts running — provisioning laptops, managing identity/SSO, handling support tickets, patching, monitoring. Good ops people are calm under pressure and have a documented runbook for everything.
Typical skills: Windows/macOS admin, Active Directory or Okta/Google Workspace, networking basics, scripting (PowerShell/Bash), ticketing systems
Salary insights (US, rough)
Typical range for it / systems admin roles in the US is $50,000–$130,000/year, varying widely with seniority, company stage, and city.

How to prep for the interview
IT interviews include both technical scenarios (e.g. "Walk through how you'd troubleshoot a user who can't access their email") and behavioral / customer-service rounds — IT people deal with frustrated users daily, and tone matters as much as competence.
Be ready for: Active Directory / SSO / identity questions, networking basics (DHCP, DNS, VPN), scripting questions (PowerShell or Bash — be honest about your level), and a question about incident response ("A user opened a suspicious email — what do you do?"). Senior IT roles add infrastructure-as-code, monitoring, and disaster-recovery planning.
Where this role typically leads
IT progression: Help Desk → Junior Sysadmin → Sysadmin → Senior Sysadmin → IT Manager / Director of IT. Many senior sysadmins pivot to DevOps / SRE / Cloud Engineering for significantly higher pay — learning AWS / GCP / Azure deeply and picking up infrastructure-as-code (Terraform) is the highest-ROI move for someone with 3+ years of sysadmin experience.
Certifications matter more here than in software engineering: Microsoft, AWS Solutions Architect, CISSP (for security-leaning paths) are widely respected. Don't collect them indiscriminately — pick one that aligns with where you want to go in 2 years and go deep.
Red flags to watch for
- Sole IT person at a company over 50 people. Means you're on call 24/7, vacation is risky, and any project takes forever. Ask how the company has scaled IT support so far.
- "Other duties as assigned" listed prominently. Means the role's scope is whatever leadership decides this week. Push for a more specific JD or expect chaos.
- No mention of monitoring or observability tools. Means infrastructure failures are detected by users calling support, not by alerts. Reactive firefighting all day.
- "On-prem only" at a company under 200 people. Increasingly rare — usually means stuck on legacy infrastructure that nobody wants to migrate. Skill stagnation risk.
