About The Position

DNV Energy Systems is seeking a Senior Process Engineer to join its Low Carbon team. The role supports clients’ energy-transition efforts by identifying tailored solutions and maintaining expertise in low-carbon fuels, LNG as a fuel and feedstock, hydrogen and hydrogen-derived products, and related processes. The team provides technical due diligence focused on green and blue hydrogen production and supply-chain integration; production of derivatives such as ammonia, methanol, and synthetic fuels; LNG production; and natural-gas power applications combined with carbon capture and sequestration. The engineer will model processes at different facility scales, prepare Front-End Loading (FEL) documents from opportunity identification (FEL 0) through Select (FEL 2), and support client strategic decision-making. The position also contributes to team knowledge development, proposals, and multiple projects in a fast-paced environment. It may be based at DNV offices in Seattle, Houston, Oakland, Medford, or Portland, or may be considered at other DNV offices in the continental United States. The role follows a hybrid schedule, typically with three days per week at a DNV office or client location/site.

Experience as a capital-project team member through development stages, including FEL 0 to FEL 3, construction, commissioning, and operations.
Ability to prepare Class 5 to Class 4 cost estimates under AACE.
Ability to estimate life-cycle greenhouse-gas emissions and use standard life-cycle assessment (LCA) tools.
Knowledge of hydrogen, ammonia, methanol, synthetic-fuel processes, LNG, and CCS.
Master competence level in Process Safety.
Excellent written and oral communication skills, including the ability to communicate technical information to subject-matter and non-subject-matter audiences.
Strong project-management and change-management skills.
Ability to work on multiple tasks concurrently during a workweek.
Results- and documentation-oriented work philosophy, strong attention to detail, and desire to grow.
