Newlight’s mission is to accelerate the maritime industry’s transition to sustainable energy by making clean shipping affordable, starting with today’s fleet. We retrofit existing engines with a hydrogen-diesel dual-fuel “plugin” that reduces fuel consumption and emissions.
We’re seeking a Lead Process Engineer to own the end-to-end ammonia/Methanol cracking process, from NH₃ feed to engine-grade hydrogen. You will define performance targets, build process models, specify equipment, and translate system requirements into vendor-ready designs.
This role is ideal for a senior process engineer who thrives on thermodynamics, gas systems, and turning flowsheets into deployable hardware.
What You Will Be Doing
- Define the complete process chain: NH₃ vaporization and preheat, cracking reactor, heat recovery, NH₃ slip mitigation, drying/filtration, compression, and buffering.
- Build mass and energy balances and steady-state process models (Aspen/HYSYS preferred; Python or spreadsheets acceptable).
- Specify product gas targets (H₂ purity, NH₃ slip, dew point), turndown ratios, ramp rates, and operating envelopes.
- Author equipment specifications for reactor, heater, heat exchangers, separators, scrubbers/adsorbers, compressors, valves, and instrumentation.
- Develop PFDs and P&IDs; maintain process datasheets and instrument lists.
- Lead RFQs with vendors, evaluate bids, and support technical sourcing decisions.
- Define utility loads (electrical, thermal, cooling) and system performance assumptions.
- Collaborate closely with Mechanical, Electrical, Controls, and Safety on integrated system design, HAZID/HAZOP, and commissioning readiness.
Requirements We Seek
- Bachelor’s degree in Chemical Engineering or related field.
- 3+ years in process or chemical engineering, ideally with high-temperature gas systems.
- Hands-on experience with catalyst reactors, furnaces/heaters, and gas cleanup technologies (adsorption, scrubbing, PSA, membranes).
- Strong ability to translate process requirements into vendor-ready equipment datasheets.
- Experience producing PFDs, P&IDs, and process documentation.
- Clear technical communication and comfort working cross-functionally and on-site.
Ways To Stand Out
- Direct experience with ammonia/Methanol or hydrogen systems.
- Marine integration or shipboard process systems.
- Hazardous-area design exposure.
- Python-based modeling or custom process tools.
- Prior ownership of commissioning or performance validation of gas-process equipment.
Why Join Newlight?
- Own the system logic: You will define how ammoniaMethanol becomes clean hydrogen at sea.
- Build something real: Take models and turn them into operating vessels.
- Shape the roadmap: Influence architecture as we scale from pilots to fleets.
- Mission with momentum: Deliver decarbonization on today’s ships, not future concepts.
