Description

GeoStabilization International (GSI), Access Limited, and RoadGuard together form a leading infrastructure solutions platform dedicated to protecting people and strengthening critical infrastructure across North America and New Zealand.

GSI is the premier geohazard mitigation firm specializing in emergency slope stabilization, landslide repair, grouting, and micropiles through innovative design-build delivery. Access Limited brings over a century of steep-slope expertise and operates North America’s largest fleet of spider excavators, delivering complex rockfall and geotechnical solutions in the most challenging environments. RoadGuard, founded in 2024, unites industry-leading roadway safety companies providing guardrail, bridge railing, highway signage, fencing, and specialty fabrication services.

Across all our businesses, we are driven by innovation, extreme ownership, technical excellence, and a relentless commitment to measurable results that improve safety and infrastructure resilience.

NOTE: GSI is not sponsoring VISA holders or relocating for this role. You must be within commutable distance AND have a US Citizenship/Permanent Residency to be considered.

GSI is looking for a Systems Administrator I/II to own the reliability, performance, and security of our on-premises and cloud infrastructure. This is a hands-on technical role, but it's also a proving ground. We are not hiring for adequacy — we are hiring for excellence: candidates with the intellectual horsepower, resilience, and results orientation to take extreme ownership of GSI's systems and scale into senior engineering or IT leadership. Outcomes matter more than hours logged or tickets closed.

Level (I or II) is determined by the candidate's demonstrated experience and technical depth.
