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 (Aspe...
