Combustion Engineer Job Northern Kentucky USA,Engineering

Develop the dual-fuel combustion strategy across hydrogen substitution, diesel pilot timing, lambda and EGR control, rail pressure, and split injection.
Plan and execute design-of-experiments work on dynamo meters and vessels, including emissions and cylinder-pressure instrumentation.
Analyze heat release, CA50, knock, ringing intensity, IMEP, fuel consumption, NOx, particulate matter, misfire, and cycle variability.
Convert test results into usable calibrations, operating limits, release criteria, and real-time ECU protections.
Co-develop sensors, actuators, and state machines with Controls, then support simulation, HIL validation, FAT, HAT, SAT, and commissioning.

Must-have skills

Master’s degree in mechanical or aerospace engineering with a combustion or internal-combustion focus, or equivalent experience alongside a bachelor’s degree.
Hands-on engine testing and calibration experience, including cylinder-pressure analysis and emissions measurement.
Strong command of ignition delay, mixing, knock, emissions formation, aftertreatment interactions, and other combustion fundamentals.
Ability to turn analysis into runnable maps and limits on real-time ECUs.
Clear technical documentation and disciplined, data-led problem solving.

Preferred experience

Marine or heavy-duty engines and hydrogen or alternative-fuel dual-fuel systems.
Model-based development and hardware-in-the-loop validation.
Functional-safety concepts and familiarity with ABS, DNV, IGF, or USCG requirements.

Tools

MATLAB and Python for analysis and post-processing.
INCA or ATI for ECU calibration and map development.
CAN, UDS, and XCP workflows for logging and diagnostics.
GT-SUITE, CONVERGE, or STAR-CCM+ for combustion modeling, plus basic CAD for test-hardware interfaces.

What we offer

Competitive salary and equity package.
Ownership of combustion strategy and calibration for Newlight’s hydrogen-diesel technology.
Hands-on testing in dynamometer facilities and aboard vessel deployments.
The opportunity to work on dual-fuel systems that directly reduce fuel consumption and shipping emissions.
