Software Engineer, AI Infrastructure

Harell Data • Palo Alto, CA

3d • Onsite

About The Position

You'll be an early engineer reporting directly to the CTO. You'll own the compute layer: the GPU clusters and the inference systems that run on them. You'll make the architectural decisions that define the platform. You'll also work directly with customers to understand what they actually need and turn that into infrastructure that works at scale.

Requirements

• 5+ years building and operating production infrastructure, with a focus on ML workloads: training, inference, or data pipelines
• Hands-on experience with Kubernetes on AWS or GCP, ideally with GPU workloads.
• Strong CS fundamentals and system design chops
• Comfortable with ambiguity — you've worked somewhere where the playbook didn't exist yet

Responsibilities

• Build the GPU compute layer - Orchestration for GPU workloads on Kubernetes: resource allocation, scheduling, multi-tenancy, and cost management.
• Build the inference layer - Model loading, autoscaling, batching, and serving. You own the latency and throughput customers feel.
• Own the ML pipeline end to end - Data ingestion, preprocessing, training and fine-tuning jobs, and recovery when multi-node jobs fail.
• Work directly with customers - Debug fine-tuning jobs that fail or run slow. Build the observability that tracks model performance and resource health in real time.
• Own reliability - Incident response, on-call, and keeping the platform up as usage grows.
• Shape technical direction - Lead build-vs-buy decisions on infrastructure and security. Set engineering standards. Help hire the team you want to work with.
