Job Description

Ready for Your Next Technical Challenge?

If you're the engineer others turn to when the easy answers haven't worked, this may be the opportunity for you.

Van Ausdall & Farrar (VAF) is looking for an experienced Senior Infrastructure & Systems Engineer (L3) to serve as a top-tier technical resource within our Managed IT Services team.

Unlike supporting a single corporate environment, you'll work across a diverse client base—solving complex infrastructure challenges, designing and implementing solutions, leading technical projects, and helping shape how our clients' environments evolve.

This is a hands-on senior engineering role for someone who enjoys digging into difficult problems, working across technologies, sharing knowledge, and taking ownership from initial diagnosis through resolution.

And one more thing: we're looking for someone who likes people, too.

Yes, we need serious technical chops—but this isn't a role where you can hide behind a screen all day. Our engineers work directly with our customers, and we're looking for someone who can walk into a room, build trust, explain a complex technical issue without speaking entirely in acronyms, and confidently lead a customer conversation.

If you can troubleshoot a complex infrastructure problem and explain what happened to a customer without making their eyes glaze over, you'll fit in well here.

Salary: $90,000–$110,000, based on experience
Location: Indianapolis, IN
Work Arrangement: Onsite
Position: Full-time

This position is based in our Indianapolis office. Remote work and relocation assistance are not available at this time. Local candidates are strongly encouraged to apply.

This is an MSP environment. The person isn't being asked to sit in an office five days a week to answer Teams messages they could answer from their couch. They're collaborating with engineers, working hands-on with infrastructure, leading projects, troubleshooting complex client environments, interacting with customers, mentoring L1/L2 engineers, etc.

• Translate business and technical requirements into effective infrastructure solutions.

• Develop architecture diagrams, build documentation and knowledge-base resources.

• Provide technical mentorship, peer review and training to L1 and L2 engineers.

• Participate in onboarding and technical skills development for other members of the engineering team.
