Tallgrass

Tallgrass operates more than 7,000 miles of FERC-regulated natural gas transportation and storage infrastructure across the United States. That's over 10.3 billion cubic feet per day of pipeline capacity and roughly 25 Bcf of storage - critical national energy arteries including the Rockies Express Pipeline (REX), Ruby Pipeline, and Trailblazer Pipeline, among others. Founded in 2012 and headquartered in Lakewood, Colorado, with offices in Houston and Leawood, Kansas, the company sits at the intersection of operational technology and the broader energy grid's attack surface.

For cybersecurity professionals, the threat model here is physical-cyber convergence at scale. FERC-regulated pipeline systems, SCADA environments, industrial control systems spanning gathering, processing, transportation, and storage - these are high-value targets where a compromise doesn't just mean data loss. The company's decarbonization initiatives add additional digital transformation layers, expanding the environment that needs defending. The operational footprint is massive and geographically distributed, which means lateral movement, remote access, and OT/IT network segmentation are not theoretical exercises.

Working at Tallgrass means engaging with the security challenges of critical energy infrastructure where uptime, safety, and regulatory compliance aren't aspirational - they're baseline. The team is protecting systems that move a significant percentage of U.S. natural gas supply daily. Candidates will encounter environments that demand fluency in both traditional IT security and the realities of industrial control system protection, with the added complexity of a company actively evolving its energy portfolio toward lower-carbon operations.
