POSITION SUMMARY

The Infrastructure & Security Engineer is a key technical role on DSI’s IT team, responsible for the hands-on execution of infrastructure operations and cybersecurity defense across a multi-warehouse logistics environment. You will also contribute to desktop engineering and participate in the team’s rotating helpdesk coverage—areas shared across the IT group, not carried solo. DSI’s IT team operates a structured Lean IT model that protects dedicated deep-focus time for infrastructure and security project work every day, while maintaining responsive, customer-facing support during scheduled rotation blocks. You won’t be context-switching constantly—the model ensures you have the space to do meaningful work. The ideal candidate brings strong systems and networking fundamentals, a security-aware mindset, and the willingness to grow into areas where they don’t yet have deep expertise. We invest in our people through mentorship and a team culture that values learning over perfection.

WHY DSI?

This isn’t a ticket factory. DSI’s IT team operates a structured Lean model that gives you protected time for deep infrastructure and security work every single day. You’ll own real projects—not just put out fires. Support rotations and facility walks keep you connected to the business so your project work is grounded in what you see on the ground.

We’re looking for someone strong in at least one discipline—infrastructure or security—with the drive to grow in the other. DSI supports that growth with structured mentorship, dedicated learning time, and a team culture that values development over perfection. If you’ve outgrown a pure sysadmin role, or you’re a security-minded engineer who wants to own infrastructure too—within a lean, high-trust team without the bureaucracy of a large enterprise—we should talk.
