Research Engineer, AI Training & Deployment Pipelines

Mistral; France; A distancia; EUR 85.000 - 115.000; Jornada completa

Descripción de la vacante

Mistral, a leader in full-stack AI solutions, seeks a Research Engineer on Forge to turn customer requirements into reliable training and deployment workflows—from CPT/SFT to RL and distillation. You will work end-to-end across model adaptation, evaluation, data, and infrastructure, bridging research and production constraints.

This role sits in Applied Science and collaborates with scientists, engineers, product, and customer teams to ensure Forge projects ship, remain maintainable, and are

Formación

• Strong Python engineering skills with experience in large codebases and CI.
• Hands-on experience with PyTorch, JAX, or similar frameworks.
• Strong systems and infrastructure fundamentals.
• Experience with LLM training or post-training, including fine-tuning, RL, distillation, evaluation, or data pipelines.
• Excellent debugging skills in distributed or complex systems.
• Clear communication with technical and non-technical stakeholders.
• High agency, low ego, and comfort in fast-moving environments.

Responsabilidades

• Build and improve post-training and evaluation workflows (CPT/SFT/RL/distillation).
• Develop tools and pipelines for synthetic data generation, curation, training, evaluation, and deployment.
• Debug and harden large-scale ML systems: distributed training, scheduling, checkpointing, observability.
• Improve the Forge codebase via APIs, tests, and documentation.
• Push the frontier of our RL training stack for frontier-model scale.
• Ensure Forge deployment is seamless across diverse clients (hardware, software stacks, cloud/on-prem).
• Collaborate with researchers and infrastructure engineers to translate bottlenecks into improvements.
