Life360 is looking for a Staff Firmware Engineer to serve as a foundational architect for new Machine Learning initiatives. You will be the primary bridge between Data Science and hardware execution, building the first-ever on-device ML pipelines for next-generation devices. This role is integral to our mission of connecting families through a growing ecosystem of hardware products.

What You'll Do

Drive the development and maintenance of general firmware architecture across the device portfolio to ensure overall system health and stability.
Build the technical framework for on-device inference within resource-constrained firmware stacks.
Partner with Data Science to design the company's first hardware-optimized data sampling, preprocessing, and inference pipelines.
Drive the integration of new sensors to create the frameworks required for advanced context-awareness and predictive modeling.
Solve large-scale technical challenges and drive alignment between firmware, hardware, and researchers.
Provide high-impact mentorship to help the broader firmware organization grow its expertise in embedded ML and sensor fusion.

What We're Looking For

10+ years of firmware experience, taking complex consumer hardware from prototype through mass production.
Proficient in C/C++, RTOS (Zephyr/FreeRTOS), and low-level peripheral communication (SPI, I2C, DMA).
Hands-on experience deploying TinyML models and optimizing inference on Cortex-M or similar architectures.
Deep understanding of sensor data and building the signal processing pipelines required for ML features.
A passion for squeezing maximum performance out of extreme constraints in power consumption and memory footprint.
Proficiency in Python for data analysis, hardware-in-the-loop (HIL) testing, and automating firmware pipelines.
Excellent collaboration skills with the ability to influence technical strategy across teams and stakeholders.
Bachelor’s degree in Electrical Engineering, Computer Science, or a related field.
