Remote ML Data Infrastructure Engineer

Bayside Solutions; Cupertino (CA); Remote; USD 83,000 - 96,000; Full time

Job summary

Bayside Solutions, Inc. is seeking a Software Engineer to build and operate the data infrastructure feeding ML training and inference systems. You will design high-throughput, distributed data pipelines atop columnar formats to ensure data is readily available for GPUs and models.

The role emphasizes hands-on performance engineering, collaboration with ML researchers, and designing reliable, observable data infrastructure with cost awareness. W2 contract, remote-friendly in Cupertino, CA.

Qualifications

• Extensive experience building and running large-scale distributed data or ML infrastructure in production.
• Strong programming skills in Python, plus a systems language for performance-critical work (Rust strongly preferred; C++ or Go acceptable).
• Deep familiarity with columnar and lakehouse formats (Parquet, Iceberg, Delta, or Lance) and the trade-offs between them.
• Hands-on performance engineering for I/O-bound workloads: Arrow, zero-copy, memory mapping, async I/O, and high-throughput object storage access patterns.
• Working knowledge of the end-to-end ML workflow and how training and inference workloads consume data, enough to design data systems that serve them well.

Responsibilities

• Design, build, and operate large-scale distributed data systems that serve ML training and inference workloads in production.
• Strong Python Engineer.
• in Rust (or C++/Go) with Python bindings for ML practitioners to build high-performance data loading, storage, and retrieval layers (Systems Performance, which is critical work)
• Evaluate and adopt columnar and lakehouse formats (Parquet, Iceberg, Delta, Lance), and make the trade-offs explicit for schema evolution, random access, scan performance, and versioning.
• Optimize I/O-bound pipelines using Arrow, zero-copy techniques, memory mapping, async I/O, and efficient object storage access patterns (request coalescing, prefetching, caching, parallel range reads).
• Profile and remove bottlenecks across the data path, from object storage to host memory to accelerator, so training and inference stay compute-bound rather than I/O-bound.
• Partner with ML researchers and engineers to understand how training loops, evaluation, and inference services consume data, and turn that into system requirements.
• Define reliability, observability, and cost standards for data infrastructure, including SLOs, monitoring, capacity planning, and incident response.
• Write design documents, review code, and mentor engineers on performance engineering and distributed systems practices.
