Commissioning & Startup Engineer

Position Responsibilities:

The Commissioning & Startup (CSU) Engineer will play a key role in the safe and efficient handover of complex cryogenic facilities—including LNG systems, Gas Processing Units, Air Separation Units, Liquid Hydrogen Plants, and similar facilities—to end clients. This role involves extensive global travel, including offshore assignments, and is best suited for candidates who bring a strong safety mindset without overcomplicating or delaying operational goals.

• Lead commissioning and startup of cryogenic facilities, ensuring safe operations and performance targets are achieved.
• Perform detailed P&ID walkdowns and generate punch lists to resolve plant discrepancies.
• Execute machinery field run tests with vendors, validating machinery controls and protection systems.
• Oversee control loop checks, ensuring proper function of alarms, shutdowns, valve operations, and compliance with Control Narratives and Cause & Effect Matrices.
• Tune PID loops using Ziegler-Nichols or similar methodologies.
• Manage cooldown and startup of cryogenic systems, using techniques such as Joule-Thomson (JT) effect, expanders, and various heat exchanger types (BAHX, CWHE, PFHE).
• Start up compressors, gradually shifting from recycle mode to normal operation.
• Dry out, derime, and defrost cryogenic systems in preparation for startup.
• Develop operating manuals and startup procedures based on engineering designs.
• Participate in design reviews, HAZOPs, and contribute commissioning feedback during early project phases.
• Conduct training sessions for operators both before and after commissioning.
• Perform site inspections and document lessons learned for future improvements.

Position requirements:

• 3+ years of hands-on commissioning/startup experience in cryogenic systems or similar (e.g., LNG, air separation, gas processing, Liquid H2).
• Deep understanding of cryogenic processes, including gas expansion cooling via JT effect and system-specific cooldown management.
• Prior experience conducting full commissioning cycles—from mechanical completion to initial operation.
• Practical safety orientation that emphasizes efficiency and avoids unnecessary production delays.
• Proficient in troubleshooting and evaluating performance of systems and equipment.
• Skilled in process simulation tools such as HYSYS, Unisim, or Pro/II.
• Strong grasp of applicable engineering standards (ANSI, ASME, API, ASTM).
• Bachelor’s degree in Chemical or Mechanical Engineering.
• Excellent interpersonal and communication skills.
• Willingness and ability to travel extensively.

Travel Requirements:

• U.S.-based sites: Typical travel duration 1 to 4 weeks per trip.
• International sites: Typical travel duration 3 to 6 weeks per trip.
• Offshore FLNG sites: Typical travel duration 4 to 8 weeks per trip.
• Must be comfortable working in offshore and remote environments across the USA, Middle East, Asia, Africa, and Europe.

Reasons to Apply:

• Competitive salary plus a comprehensive benefits package.
• Health coverage, retirement plans, and other company-sponsored perks.
• Generous paid time off, including holidays, to support work-life balance.
• Flexible schedules and work life balance.
• Strong focus on employee development with on-the-job training and career growth.
• A positive company culture that values diversity and collaboration.
