Job Overview

We are seeking a highly skilled and motivated Senior Engineer to lead Emergency Relief System (ERS) design projects. This role involves performing reactive chemical hazard analysis using advanced adiabatic calorimetry techniques. The position requires advanced technical knowledge in process safety, thermal runaway behavior, and two-phase vent sizing, with hands-on expertise using adiabatic reaction calorimeters such as PHI-TEC II, APTAC, and/or VSP2.

Responsibilities

• Lead the design and analysis of Emergency Relief Systems (ERS) in accordance with DIERS methodology, API 520/521, ASME B31.3, and other relevant industry standards.
• Operate and maintain the PHI-TEC II adiabatic reaction calorimeter to characterize thermal runaway and pressure generation behavior of reactive chemicals.
• Analyze calorimetry data to determine heat release rates, pressure rise rates, time to maximum rate (TMR), and vent sizing requirements.
• Perform two-phase flow and homogeneous equilibrium model (HEM) calculations to support design of rupture disks, pressure relief valves, and containment systems.
• Author clear and concise technical reports summarizing test results, ERS sizing calculations, and risk mitigation recommendations.
• Collaborate with clients, project managers, and multidisciplinary teams, fostering a respectful and inclusive working environment where diverse perspectives contribute to the best outcomes. (e.g. PHA, HAZOP, LOPA)
• Engage in business development activities to help grow and strengthen this service line.

Requirements and Qualifications

• Bachelor’s or Master’s degree in a relevant engineering discipline.
• Minimum 5 years of experience in process safety engineering, with a focus on ERS design and reactive hazard evaluation.
• Demonstrated success working in the consulting industry with diverse clients and project teams.
• Strong understanding of vent sizing methodology, two-phase flow, and reactive chemical systems.
• Proficiency with pressure relief sizing software tools.
• Excellent technical writing and communication skills, with the ability to convey complex information to varied audiences.
• PE license and/or CSP certification is a plus.
