About the role

As an MLOps Engineer, you will focus on optimizing, deploying, and operating large-scale machine learning models that power Boltz Lab. Your primary responsibility will be to ensure that advanced models for molecular modeling and design run efficiently, reliably, and cost-effectively across distributed systems. You will work closely with ML Researchers to take trained models and turn them into production‑ready services by optimizing training and inference performance, reducing memory and compute overhead, and scaling workloads across multi‑GPU and cloud environments. This includes profiling, improving model throughput and latency and hardening systems for long‑running and high‑volume workloads. This role is ideal for someone who thrives on technical ownership and operational excellence, enjoys working close to systems and infrastructure, and is motivated by deploying high‑impact machine learning systems at scale for real‑world scientific use.

About you

Essentials:
