About Nebius:

Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.

Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.

Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.

The role
This position sits within Nebius Token Factory, our serverless platform for running and customizing open-source LLMs in production. Token Factory allows for serverless inference and fine-tuning (LoRA, full FT, RFT) backed by in-house optimizations like custom speculative decoding, quantization, cache-aware routing and dedicated endpoints. Customers come to us to move from prototype to scaled production without the cost and complexity of building and tuning their own inference stack.
We seek an experienced Senior ML Solutions Architect to support customers leveraging Nebius Token Factory's serverless inference and fine-tuning platforms for open-source LLMs across multiple modalities. In this role, you will be collaborating with clients to design and implement optimized inference workflows, build customized LLM-based solutions and architect scalable AI applications using our served models. You will also work closely with our backend team to improve our platform to match clients' needs.
You’re welcome to work remotely from Europe.
Your responsibilities will include:

• Optimize LLM inference across various modalities to drive business value and support customer goals

• Provide support in supervised and reinforcement learning fine-tuning to maximize model quality for the customers

• Design and implement LLM-based solutions using Nebius Token Factory’s inference services

• Build production-ready applications leveraging our serverless LLM APIs, including multimodal models (text, vision, audio) and domain-specific models

• Provide technical expertise in prompt engineering, RAG architectures and model selection

• Collaborate with product and engineering teams to surface customer feedback and shape the platform roadmap

• Guide customers in scaling from POC to production with a focus on performance, reliability, and cost efficiency

We expect you to have:

• 5+ years of experience in ML/AI systems, with at least 2 years focused on LLMs and generative AI

• Deep knowledge of the LLM ecosystem, including model architectures and fine-tuning approaches

• Hands-on experience with:
• Running LLMs in production: deploying and operating inference workloads

• LLM fine-tuning, including supervised fine-tuning (SFT/LoRA) and data preparation/curation; experience with RL-based fine-tuning is a strong plus

• LLM evaluation: building task-specific benchmarks and offline/online eval pipelines, including LLM-as-a-judge setups

• Inference frameworks and libraries (e.g., vLLM, SGLang, TensorRT-LLM, Transformers)

• Deploying LLM-powered applications using APIs from OpenAI, Anthropic, or open-source models

• Strong Python programming skills

• Excellent communication skills, with the ability to clearly explain technical concepts to diverse audiences

It would be an added bonus if you have:

• Work with multimodal AI models (e.g., vision-language, speech)

• Proficiency with DevOps tools (Docker, Kubernetes)

• Contributions to open-source ML/AI projects

Preferred technical stack:

• Programming Languages: Python

• ML Frameworks and Libraries: vLLM, TensorRT-LLM, SGLang, Transformers, OpenAI/Anthropic SDKs

• MLOps and DevOps tools: Kubernetes (K8s), Docker, Git

• Cloud Platforms: AWS (SageMaker, Bedrock), GCP (Vertex AI), Azure (Azure ML)

Benefits & Perks:

• Competitive compensation

• Career growth and learning opportunities

• Flexibility and ownership

• Collaborative and innovative culture

• Opportunity to work on impactful AI projects

• International environment and talented teams

What's it like to work at Nebius:

Fast moving - Bold thinking - Constant growth - Meaningful impact - Trust and real ownership - Opportunity to shape the future of AI
