Newlight

Alameda, California · On-site · Full-time

Mechanical Design Engineer

Lead mechanical systems development for Newlight’s hydrogen-injection retrofit across customer vessels and in-house test cells.

Define the mechanical architecture for the hydrogen-injection package and its piping, mounts, enclosures, ventilation, and heat-rejection systems.
Release production-ready CAD, assembly and detail drawings, weldments, GD&T, bills of materials, and revision-controlled documentation.
Create and maintain PFDs, P&IDs, line lists, specification sheets, and mechanical interface-control documents.
Design skids, brackets, enclosures, serviceable layouts, and vibration-isolated mounts for constrained marine engine rooms.
Size and route hydrogen, air, coolant, and fuel piping while selecting marine-ready valves, regulators, hoses, fittings, and supports.
Support vessel surveys, integration planning, FAT, HAT, SAT, commissioning, and on-site installation.
Coordinate vendors and fabricators while reviewing quotations, tolerances, coatings, and design-for-manufacture decisions.

Bachelor’s degree in mechanical engineering or a closely related discipline.
At least three years of experience shipping real marine, industrial, or transportation hardware in a hands-on engineering environment.
Strong CAD and drawing skills, with close attention to clear callouts, tolerances, access, and serviceability.
Comfort working in the shop and aboard vessels—measuring, fitting, torquing, leak-checking, and troubleshooting hardware.

Gas and liquid piping or tubing systems, including vibration, expansion, routing, and support design.
Skids, sheet metal, machined parts, weldments, enclosures, and marine materials or coatings.
Static-strength and vibration FEA, plus practical thermal analysis for ventilation and heat-rejection paths.
Marine requirements such as ABS, DNV, the IMO IGF Code, or USCG guidance.
Hydrogen or alternative fuels, hazardous-area design, HAZID or HAZOP work, and point-cloud-to-CAD workflows are valuable additions.

SolidWorks, including assemblies, weldments, drawings, and PDM.
AutoCAD or Plant 3D for P&IDs and layout, with Navisworks or an equivalent fit-check workflow.
ANSYS or SolidWorks Simulation for FEA; basic CFD knowledge is useful.
Standard metrology, assembly, torque, pressure, vacuum, and leak-test equipment.

Competitive salary and equity package.
Ownership of mechanical systems from concept through vessel installation.
Hands-on work with hydrogen technology, test cells, vessel integrations, and field commissioning.
Meaningful opportunities for professional growth and technical leadership.

Alameda, California · On-site · Full-time

Own combustion physics and calibration for Newlight’s hydrogen-diesel retrofit, from test strategy to vessel-ready engine maps.

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 dynamometers 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.

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.

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.

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.

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.
