Description

This is an machine learning engineering role at the HW/SW/UI boundary, with broad collaboration opportunities across firmware, software, and algorithms teams. You will be responsible for developing sensing algorithms using signal processing and machine learning techniques and delivering them as highly optimized, power-efficient code for custom silicon. You'll tackle complex challenges like memory constraints, computational budgets, and real-time performance while ensuring robust end-to-end functionality from sensor data acquisition through to the software layer to deliver exceptional user experiences. In this role, you will also lead efforts to identify, evaluate, and deploy GenAI tools that improve team productivity, including GenAI-assisted development, data analysis, and workflow automation. You will help define best practices for GenAI tool adoption within the group and collaborate cross-functionally to scale these efforts.

Responsibilities

Prototype and develop sensing, tracking, and classification algorithms to support new product form factors and new user-facing features Develop and integrate robust C/C++ low-level software for deploying algorithms on microcontrollers, DSPs, and ML accelerators Integrate algorithm implementations with the SW layer, ensuring correctness, performance, and stability across product configurations Work with firmware and software engineers throughout the product lifecycle, from early prototyping through productization Develop and maintain integration test frameworks and performance metrics to validate algorithm behavior end-to-end Profile and budget algorithm compute/memory workloads on embedded platforms to guide silicon architecture teams on accelerator requirements, core selection, and memory sizing for future hardware Identify and champion GenAI tools and developer productivity solutions that can be adopted within the team Evaluate GenAI-assisted workflows (e.g., code generation, data analysis, automated testing) and driving their integration into team processes Communicate findings, integration status, and tooling recommendations clearly to team members and leadership
