Sr Engineer, Subsea Engineering

Transocean•Houston, TX

About The Position

The Sr Engineer, Subsea Engineering provides senior-level engineering support and technical assurance for subsea and well-control equipment installed on floating offshore drilling rigs. The role supports worldwide operations and provides technical expertise for the safe, reliable, and compliant operation of BOP systems and control systems, marine riser systems, riser tensioning systems, BOP handling and transport equipment, and associated drilling well-control equipment. The position supports operational troubleshooting, equipment failures, engineering modifications, maintenance and reliability improvements, equipment upgrades, lifecycle management, and regulatory and classification compliance. It also supports newbuilds, upgrades, refurbishments, reactivations, and other engineering projects. The role requires independent engineering judgment, coordination with offshore personnel, OEMs, vendors, classification societies, clients, and regulatory stakeholders, and technical leadership during routine operations and time-critical operational or NPT events.
