Junior Software Engineer (Embedded Controls)

Location: Bay Area, CA (on-site) · Type: Full-time · Team: R&D Controls

About Newlight

Newlight accelerates maritime decarbonization by making sustainable shipping affordable—today. We retrofit existing diesel engines with a hydrogen-injection plugin that cuts fuel use and emissions.

What You’ll Do

Write C code for microcontrollers that open/close valves and drive actuators (solenoid valves, pumps, relays).
Implement state machines, safety interlocks, and basic control logic (timers, debouncing, fault handling).
Read sensors (pressure, temperature, flow) via ADC/I²C/SPI/UART, and trigger outputs (PWM/GPIO).
Support hardware bring-up, bench testing, and HIL setups; log and analyze data from DAQ.
Help with wiring diagrams, test protocols, and clear documentation for lab and on-board engine tests.
Work hands-on with senior controls/ME teams to integrate the hydrogen-diesel dual-fuel system.

Minimum Qualifications

B.Sc. in Electrical/Controls/Computer Engineering or similar (or equivalent experience).
0–2 years experience (internships and projects welcome).
Solid C programming skills on embedded targets (e.g., STM32 / TI / NXP or Arduino-class MCUs).
Basic electronics/debug skills (reading schematics, multimeter/scope use, safe lab practices).
Familiarity with one or more comms: UART/CAN/Modbus.
Strong problem-solving, willingness to learn, and on-site lab work comfort.

Nice to Have

Experience driving solenoid valves, pumps, or other actuators (PWM, current limiting, flyback diodes).
Exposure to RTOS basics, bootloaders, or watchdogs.
Python for test scripting; MATLAB/Simulink exposure is a plus.
Background or interest in marine/automotive engines, combustion, or hydrogen systems.
Experience with DAQ, HIL, or safety-critical systems.

Why Join Newlight?

Ship real hardware that reduces emissions now—not in 10 years.
Build end-to-end skills across embedded, controls, and powertrain integration.
Small, mission-driven team with clear growth paths (own subsystems, lead features).
