Summary: The ML Engineer role is primarily focused on the end-to-end development of machine learning models, encompassing data ingestion, model training, evaluation, and deployment processes. This role is crucial in enhancing the organization's machine learning capabilities and delivering improved models for various applications.

Responsibilities:

• Enhance encoder models to boost model capacity and resolution.

• Develop multi-classification support for diverse map-feature attributes by establishing a complete data pipeline, training models, and conducting evaluations.

• Port a large-scale inference pipeline to C, and develop a CLI along with a frontend for job management, as well as create a plugin interface for results visualization.

• Migrate CoreML inference to MLX for cross-OS model execution.

• Train a confidence and ranking model based on outputs from existing autoregressive models.

• Implement curriculum training by ranking tasks based on difficulty and automating the progressive scheduling of training data.

Key Requirements:

• Proficient in Python with experience in the full model development lifecycle (data pipelines, training, evaluation, deployment).

• Strong understanding of encoder architectures, autoregressive models, or self-supervised pre-training methodologies.

• Familiarity with CoreML, MLX, or similar inference frameworks.

• Experience in building data pipelines through to model serving and frontend integration.

Nice to Have:

• Proficiency in C or C++ for inference porting tasks.

• Knowledge of curriculum learning or training-data scheduling techniques.
