Advanced R&D Engineer Scientist

The LNG Technology & Products team delivers competitive LNG technology solutions, develops new products, and improves existing designs and processes. The incumbent is responsible for leading complex research and technology development programs, defining technical strategy, designing and developing process cycles, designing experiments, analyzing results, and translating learnings into improved heat exchanger designs, engineering methods, and commercial offerings.  

You will report directly to our Sr R&D Manager and you’ll work out of our Allentown, PA location.

This is an individual contributor research process engineering role with a focus on process cycle and new technology development for the LNG industry. The role requires a creative and innovative approach, strong chemical engineering fundamentals, and the ability to influence across R&D, product management, process engineering, commercial, and operations teams. Ideally, the candidate will have deep experience designing and optimizing process cycles using simulation tools, along with LNG production, liquefaction, gas separation, cryogenic equipment, and heat exchanger technology experience. The candidate will be expected to solve complex and ambiguous technical problems involving two-phase fluid flow, gas separation, heat transfer, thermodynamics, heat exchanger design, and cryogenic equipment performance. This position involves up to 10% travel to domestic and global locations.

YOU MUST HAVE

•    Bachelor’s degree from an accredited institution in a technical discipline such as science, technology, engineering, mathematics
•    Minimum 5 years of experience in a technology development, R&D, or process engineering role in industrial gases, LNG, cryogenic technologies, or related process industries; detailed knowledge of cryogenic technologies such as hydrocarbon cryogenics and LNG
•    Strong fundamental knowledge of heat transfer, fluid mechanics, thermodynamics, phase behavior, and cryogenic process design.
•    Demonstrated steady-state process simulation experience and ability to apply simulation results to process cycle development, equipment design, and technology decisions.
•    Proven ability to lead technically complex projects or workstreams with cross-functional stakeholders and translate ambiguous problems into executable research or development plans.
•    Demonstrated capability to develop, validate, and deploy engineering models, methods, or design tools.
•    Strong technical communication skills, including the ability to present complex technical findings, recommendations, and trade-offs to senior technical and business stakeholders

WE VALUE

•    8 years of experience in LNG liquefaction, pre-treatment, gas separation, cryogenic technology, industrial gases, or chemical manufacturing technology development.
•    Ph.D. or advanced degree in Chemical Engineering or a related technical discipline.
•    Deep expertise in LNG process cycles, cryogenic heat exchanger design, two-phase flow, advanced thermodynamics, and/or equipment performance modeling.
•    Patent writing and filing experience, with a track record of identifying and protecting differentiated technology.
•    Experience leading stage-gated technology development programs from concept through validation, scale-up, commercialization, or deployment.
•    Ability to mentor technical talent, influence without direct authority, and create a positive and productive technical work environment.
•    Excellent oral and written communication, organizational, interpersonal, and stakeholder management skills.
•    Creates business value by delivering results with urgency, technical rigor, and a strong focus on safety, sustainability, quality, and customer needs.
