 + System engineering: Strong proficiency in Python alongside a solid understanding of modern Perception pipelines, benchmarking tools, and infrastructure.
 + Execution: Demonstrated ability to drive progress across a complex, multi-domain system, in a fast-paced environment., * Experience in one of the following auto-labeling applications: mapping, lanes auto-labelling or object auto-labelling.
 * Experience in Lidar-free auto-labeling
 * Experience in mapping, especially from multiple vehicle passes and/or lidar-free mapping.
 * Experience in complex,multi-modal, large-scale data flywheel
 * Experience with multiple modalities (e.g., cameras, LiDAR, Radar).
 * Experience with onboard edge deployment, cloud inference architectures, and balancing compute/efficiency trade-offs

## Description

Auto-labelling is a foundational pillar of the Autonomy stack. In this Senior ML Engineer role, you will play a key role in delivering high-quality, scalable auto-labeling models. This includes training, optimizing and shipping auto-labeling models in the Autonomy stack. Use cases include mapping, lanes auto-labelling, object auto-labelling as well as other critical applications. You will ship production-grade models that push the boundaries of what's possible. As such, you will also contribute to the whole end-to-end ML lifecycle & data flywheel of this effort: data acquisition, metrics definition, evaluation, model performance optimization, feedback loop. A key part of the role is especially dedicated to lidar-free auto-labeling, i.e. ship auto-labeling models that do not require lidar data.

 * Deliver prod-grade, high-quality, scalable auto-labeling models. Use cases include AV mapping, lanes auto-labelling and/or object auto-labelling, among other critical applications.
 * Train, optimize, ship auto-labeling models in the Autonomy stack, and continuously improve their performance.
 * Deliver auto-labeling with and without lidar data.
 * Establish rigorous evaluation and monitoring benchmarks. Identify and root-cause top-tier system anomalies, prioritizing high-impact optimizations to continuously push the needle on performance.
 * Partner closely with the Autonomy group to ensure we meet the feature requirements
