This role focuses on the infrastructure that powers reliable, scalable machine learning inference across cloud and customer environments.
You’ll own the systems that execute models for both large-scale batch workloads and real-time APIs.
Your work will directly influence availability, latency, throughput, GPU utilization, and the cost of every prediction.
You’ll build and evolve Kubernetes-based inference infrastructure while solving challenging problems in scheduling, scaling, recovery, security, and isolation.
The role combines hands-on systems engineering with a strong product mindset, treating compute efficiency and operational reliability as core product features.
You’ll work across model serving, batch execution, data processing, GPU optimization, and customer-hosted infrastructure.
It’s an opportunity to take broad ownership of production ML infrastructure where technical decisions have measurable customer and business impact.

Evolve and operate a Kubernetes-based online and batch inference runtime supporting production machine learning workloads.
Run large-scale batch inference through ephemeral jobs, implementing multi-dimensional admission control across CPU, memory, and GPU resources.
Build and extend Kubernetes controllers and custom resources to support reliable model execution and scheduling.
Optimize model inference engines and feature-processing pipelines using efficient, vectorized, and columnar operations.
Develop efficient mechanisms for serving graphs and data from Lance-based storage.
Own the execution of training, post-training, and fine-tuning jobs across both cloud infrastructure and customer-hosted Kubernetes environments.
Design and improve autoscaling strategies, GPU serving, inference performance, and infrastructure cost efficiency.
Implement comprehensive telemetry and monitoring for model execution, enabling performance, reliability, and cost optimization.
Solve complex infrastructure challenges including deterministic job sizing, checkpointing, recovery of batch workloads, difficult input files, and automated profiling of newly accepted models.
Design robust approaches to per-customer encryption, workload isolation, and secure execution across shared and customer environments.
Improve serving availability, online inference latency, batch throughput, GPU utilization, and cost per prediction or training job.
Ensure training and batch workloads complete reliably and on schedule without requiring manual intervention or repeated retries.
Write production-quality code, participate in rigorous code reviews, and take operational ownership of the systems you build.
