About this role

Yobi is hiring a remote Machine Learning Engineer focused on Inference and Serving to design and operate real-time AI systems. This full-time role is ideal for technical professionals who want to build scalable infrastructure and shape the future of ethical behavioral intelligence.

Role Overview

As a Machine Learning Engineer specializing in Inference and Serving at Yobi, the professional chosen will design, optimize, and operate the systems that bring Behavioral AI models to life in real time. This applied ML systems position involves turning trained models into performant, reliable services that power open-web and connected TV products. The person in this role will shape how models are packaged, versioned, rolled out, and observed to ensure fast and accurate predictions.

Key Responsibilities

Build and scale production machine learning serving systems, managing versioning, rollouts, rollback strategies, and live experimentation.
Implement low-latency optimizations such as model graph optimization, quantization, caching, batching, and efficient feature retrieval.
Write robust, high-performance code in languages like Go, Rust, C++, or Java while bridging to Python for model integration and analysis.
Monitor operational maturity, including tracking model drift, model lineage, and system observability from input to outcome.
Design reproducible and portable serving systems through custom runtime design, model registries, or lightweight orchestration.
Reason about model performance trade-offs in collaboration with researchers to improve deployability.

Requirements

Deep expertise in model deployment, building, and scaling production ML serving systems.
Strong low-latency mindset with knowledge in graph optimization, quantization, caching, and batching.
Systems fluency with high-performance coding skills in Go, Rust, C++, or Java, alongside Python.
Operational maturity in handling drift, lineage, and end-to-end observability.
Infrastructure intuition for making serving systems reproducible and portable.
Applied understanding of machine learning performance and model interpretation.
