Process Safety Engineer (PSM)

• BS in chemical, mechanical, process, or related engineering; ~10–15+ years of process/process-safety engineering experience with a demonstrated record independently facilitating full HAZOP/PHA studies • Multi-site or international process safety experience; working command of PSM elements (PHA, PSSR, PSI, MI interface, incident investigation); willingness to travel internationally (est. 25–40%) • Ability to apply hazard-evaluation and risk-ranking methods (HAZID, HAZOP, what-if, LOPA) and translate findings into risk-based, prioritized recommendations • Knowledge of process safety hazards specific to thermal energy storage — high-temperature stored thermal energy, high-voltage/arc-flash, pressure/steam systems, and stored-energy isolation • Ability to apply functional safety lifecycle practice (IEC 61511; SIF/SIL determination and verification) and select and justify appropriate RAGAGEP • Ability to evaluate program effectiveness using process safety leading and lagging indicators (e.g., API 754-style tiered metrics), audit findings, and global action-closure data • Ability to harmonize multi-jurisdiction regulatory and corporate requirements into a single global standard with defensible local adaptation, rather than running disconnected per-site programs • Track record of independently challenging designs and operating plans on a risk basis, including the authority to flag and halt unacceptable risk — without being the author of the controls under review • Experience leading cross-functional hazard-evaluation teams across cultures and time zones; ability to drive consensus on risk and safeguards in geographically distributed settings • Ability to prioritize the highest-risk processes and overdue safety-critical actions for resources and attention globally • Strong ability to influence and escalate across line and leadership without direct authority; experience mentoring engineers and serving as a principal technical reviewer
