Job summary

Mistral is seeking an ML Platform Engineer to build and operate the platform powering large-scale training, evaluation, and batch inference. You will develop infrastructure enabling researchers and engineers to run distributed GPU workloads reliably across clusters, hardware types, and regions.

You will own critical systems across the ML lifecycle, from workload scheduling to production operations, improving reliability and developer experience in a fast-moving frontier AI environment.

Qualifications

• 4+ years of experience in ML infrastructure, distributed systems, or Kubernetes platform engineering.
• Proficient in Python or Go and productive with distributed systems.
• Strong Kubernetes knowledge: controllers, operators, CRDs, scheduling, networking, storage, resource management.
• Familiar with GPU workloads and related technologies (PyTorch, CUDA, NCCL).

Responsibilities

• Build the ML Platform: services, APIs, controllers, and tooling for training, evaluation, fine-tuning, and batch inference.
• Orchestrate GPU workloads: queueing, admission control, quotas, priorities, preemption, topology-aware placement.
• Manage compute capacity: provisioning and allocation across clusters.
• Enable multi-cluster execution: placement based on capacity and locality.
• Improve researcher experience with self-service workflows for launching and debugging distributed workloads.
• Optimize performance: GPU utilization, scheduling latency, startup time, throughput.
• Build for reliability: observability, failure recovery, capacity planning, tooling.
• Operate what you build: participate in on-call rotations and troubleshoot across infra.

Job description

About Mistral

Mistral provides full-stack AI solutions: from frontier models to developer tools, applications, and compute. We partner with enterprises tackling the hardest problems—across high-stakes industries like finance, manufacturing, defense, healthcare, and the public sector—co-creating customized AI systems that they can run on their terms.

We are a dynamic, collaborative team passionate about AI and its potential to transform society. Our diverse workforce thrives in competitive environments and is committed to driving innovation. Our teams are distributed between Europe, North America, Asia and the Middle East. We are creative, low-ego and team-spirited.

The Role

This role focuses on building and operating the ML platform that powers large-scale training, evaluation, and batch inference at Mistral AI. You will develop the infrastructure that enables researchers and engineers to run distributed GPU workloads reliably across clusters, hardware types, and regions.

You will work across the full ML lifecycle, from workload scheduling and capacity management to platform APIs, observability, and production operations. You will take ownership of critical systems and help turn complex infrastructure into reliable, self-service capabilities.

What You Will Do

• Build the ML Platform: Develop services, APIs, controllers, and tooling for training, evaluation, fine-tuning, and batch inference.

• Orchestrate GPU Workloads: Build systems for queueing, admission control, quotas, priorities, preemption, and topology-aware placement.

• Manage Compute Capacity: Improve how heterogeneous GPU resources are provisioned, allocated, and utilized across clusters.

• Enable Multi-Cluster Execution: Place workloads based on capacity, data locality, hardware requirements, and organizational priorities.

• Improve Researcher Experience: Create self-service workflows that make distributed workloads easy to launch, observe, debug, and reproduce.

• Optimize Performance: Improve GPU utilization, scheduling latency, workload startup time, throughput, and infrastructure efficiency.

• Build for Reliability: Develop observability, failure recovery, capacity planning, and operational tooling for critical ML workloads.

• Operate What You Build: Participate in on-call rotations and troubleshoot issues across applications, schedulers, networking, storage, and GPU infrastructure.

What We're Looking For

• Have 4+ years of experience in ML infrastructure, distributed systems, Kubernetes platform engineering, or a related field.

• Are proficient in Python or Go and comfortable working with production-grade distributed systems.

• Have strong Kubernetes knowledge, including controllers, operators, CRDs, scheduling, networking, storage, and resource management.

• Understand technologies such as Kueue, Karpenter, Volcano, and Kyverno, and the problems they address in workload scheduling, provisioning, and policy enforcement.

• Understand distributed ML workloads, including training, fine-tuning, evaluation, checkpointing, and batch inference.

• Are familiar with GPU infrastructure and technologies such as PyTorch, CUDA, NCCL, and high-performance networking.

• Understand concepts such as quotas, priorities, preemption, gang scheduling, topology awareness, and workload admission.

• Can diagnose performance and reliability problems across software, orchestration, networking, storage, and hardware.

• Care about developer experience and enjoy turning complex infrastructure into simple, reliable interfaces.

• Thrive in an ambiguous, fast-moving environment shaped by frontier AI research.
