MLOps Engineer (JAX, PyTorch, Pallas/Triton)

Join a leading AI lab’s cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced Large Language Models.

# 1. Overview

Join a leading AI lab’s cutting-edge GenAI team and help build foundational AI models from the ground up. We’re seeking talented MLOps Engineers with deep, hands-on expertise in modern ML frameworks — specifically JAX, PyTorch, and kernel-level programming (Pallas/Triton) — to bring technical excellence and elevate the quality of our AI training data.

This is a W-2 employment position with Cincinnatus LLC (or appropriate international entity), with the opportunity to be placed at a leading AI Lab as part of their extended workforce.

# 2. Key Responsibilities

• Guide research and engineering teams to close knowledge gaps and improve AI model performance in MLOps, training infrastructure, and ML framework-level topics.

• Design challenging, domain-relevant tasks across multiple specializations, and write accurate and well-structured solutions to MLOps and ML systems problems.

• Evaluate MLOps tasks and solutions and provide clear, written technical feedback.

• Develop guidelines and detailed rubrics/evaluation frameworks to assess training pipeline design, distributed systems reasoning, and kernel-level optimization across tasks.

• Collaborate with other subject matter experts to ensure consistency and accuracy in training data.

# 3. Core Qualifications

• 5+ years of dedicated professional experience in ML infrastructure, MLOps, or ML systems engineering at a recognized, top-tier organization.

• Hands-on production experience with JAX and/or PyTorch at scale — including distributed training strategies (FSDP, tensor parallelism, pipeline parallelism), memory optimization, and framework-level debugging.

• Experience writing or optimizing custom GPU kernels using Pallas (JAX) or Triton — including tiling strategies, memory layout design, and kernel fusion.

• Demonstrable career progression.

• Ability to engage reliably for at least 30 hours/week during weekdays.

• Strong written communication skills and the ability to explain complex technical decisions clearly.
