Combustion Engineer

About the Position

Own combustion physics and calibration for Newlight's hydrogen-diesel retrofit.

Define the combustion recipe (air–fuel, phasing, dilution), run tests, and work closely with Controls to deliver stable, low-emission engine maps for vessel deployment.

What You Will Do

• Build hybrid strategy: H₂ substitution, diesel pilot timing, lambda/EGR control, rail pressures, split injections
• Plan and execute dyno/on-vessel DoE; instrument for emissions and cylinder-pressure indicating
• Analyze heat-release, CA50, RI/knock, IMEP/BSFC/BSNOx/PM, misfire/variability; convert insights to calibrations and ECU limits
• Co-spec sensors/actuators and state machines with Control Engineering; validate via simulation/HIL and keep models correlated (GT-SUITE/CONVERGE/STAR-CCM+)
• Write test plans, calibration notes, and release criteria; support FAT/HAT/SAT and commissioning with strong safety discipline

Must-Have Skills

• MS in Mechanical/Aero (combustion/IC engines focus) or BS + equivalent experience
• Hands-on engine testing and calibration; cylinder-pressure analysis and emissions testing
• Strong grasp of combustion fundamentals (ignition delay, knock, mixing, emissions formation, aftertreatment interactions)
• Ability to turn analysis into runnable maps/limits on real-time ECUs
• Clear documentation and data-driven problem solving

Preferred Skills

• Marine or heavy-duty engines; hydrogen/alt-fuel dual-fuel experience
• Model-based development and HIL (GT-SUITE, CONVERGE, STAR-CCM+, MATLAB)
• Functional safety and marine standards familiarity (ISO 26262 concepts; ABS/DNV/IGF/USCG awareness)

Tools

• Analysis & Simulation: MATLAB/Python for data analysis and post-processing
• Calibration Tools: INCA/ATI for ECU calibration and mapping
• Communication & Logging: CAN/UDS/XCP logging and diagnostics
• Simulation Software: GT-SUITE, CONVERGE, STAR-CCM+ for combustion modeling
• CAD: Basic CAD for test hardware interfaces

What We Offer

• Competitive salary and equity package
• Ownership of combustion strategy and calibration for groundbreaking hydrogen-diesel technology
• Work on cutting-edge dual-fuel combustion systems for maritime decarbonization
• Hands-on testing in dyno facilities and on-vessel deployments
• Make a tangible impact on reducing shipping emissions and climate change
