Embedded Controls Engineer Lead Newlight

Location : On-site

Team : Embedded Systems & Real-Time Control

Newlight is developing the worlds first scalable retrofit solution enabling hydrogen-assisted combustion for the existing global fleet. We combine advanced hardware and embedded control to deliver immediate emissions and fuel-cost reduction without replacing engines.

We are seeking an Embedded Controls Engineer Lead to architect, implement, and validate the real-time ECU controlling hydrogen-diesel combustion at sea. You will own the firmware stack and embedded technologies powering our hydrogen-injection unit, and help build the team shaping its future.

What You Will Be Doing

Own the embedded firmware roadmap and architecture across bootloader, BSP, HAL / LL, drivers, RTOS tasks, synchronization, and safety states.
Lead and mentor embedded engineers across code reviews, design reviews, planning, and hiring for scaling execution.
Implement bare-metal drivers in C for timers / ETR, input capture, GPIO, multi-channel ADC, DMA (circular / linked), UART / SPI / IC, CAN-FD, and Ethernet.
Develop the engine synchronization layer : crank / cam capture, missing-tooth detection, real-time crank-angle resolution, deterministic PWM / valve scheduling.
Build high-integrity data paths : ADC+DMA streaming pipelines, digital filtering, calibration, fixed-point math, and diagnostic thresholds.
Integrate FreeRTOS or CMSIS-RTOS v2 : priorities, ISRs, latency budgeting, inter-task messaging, watchdogs, timing analysis.
Architect fault-tolerant state machines and real-time safety logic with deterministic fallback behaviors.
Validate performance with SIL / HIL, test benches, and full-scale engines; analyze timing, jitter, and actuator response.
Support vessel integration, commissioning, and troubleshooting during early deployments.
Contribute domain input to combustion optimization and injection strategies.
Author & maintain technical documentation including control specs, schematics, timing diagrams, and validation protocols.
Ensure compliance with maritime class safety rules; drive reliability and change-control processes.

Requirements

Bachelors degree in Electrical Engineering, Computer Engineering, Mechatronics, or equivalent.

5+ years experience delivering real-time embedded control systems in production environments.

Expertise in timers, input capture synchronization, PWM / valve control, DMA pipelines, and ADC management.

Demonstrated low-latency driver development in bare-metal C on STM32-class MCUs.

Strong control-system fundamentals applied to high-speed actuation loops.

Experience with CAN-FD and industrial comms interfaces.

Solid understanding of safety-critical IO handling and diagnostic architecture.

Excellent problem-solving and communication skills; ability to thrive in hands-on, fast-iteration environments.

On-site presence required for integrated engine test cycles and cross-functional collaboration.

Nice to Have

Experience with 2-stroke and marine engine controls.

Hydrogen or hybrid powertrain experience.

Python / MATLAB tooling for DAQ, HIL / SIL or control tuning workflows.

Why Join Newlight?

Own critical firmware controlling hydrogen injection on real engines at sea your work directly reduces emissions worldwide .

Build and scale our embedded team and system architecture from pilot to fleet deployments.

Work in a highly skilled, mission-driven environment where innovation and safety go hand-in-hand.

Grow into technical leadership roles as the systems and engineering organization scale.
