AI Solutions Engineer, Pre-Sales- W&B

CoreWeave the AI Hyperscaler acquired Weights & Biases to create the most powerful end-to-end platform to develop deploy and iterate AI faster. Since 2017 CoreWeave has operated a growing footprint of data centers covering every region of the US and across Europe and was ranked as one of the TIME100 most influential companies of 2024. By bringing together CoreWeaves industry-leading cloud infrastructure with the best-in-class tools AI practitioners know and love from Weights & Biases were setting a new standard for how AI is built trained and scaled.

The integration of our teams and technologies is accelerating our shared mission: to empower developers with the tools and infrastructure they need to push the boundaries of what AI can do. From experiment tracking and model optimization to high-performance training clusters agent building and inference at scale were combining forces to serve the full AI lifecycle all in one seamless platform.

Weights & Biases has long been trusted by over 1500 organizations including Nvidia Canva Cohere Meta Snowflake Square Toyota and Amazon to build better models AI agents and applications. Now as part of CoreWeave that impact is amplified across a broader ecosystem of AI innovators researchers and enterprises.

As we unite under one vision were looking for bold thinkers and agile builders who are excited to shape the future of AI alongside us. If youre passionate about solving complex problems at the intersection of software hardware and AI theres never been a more exciting time to join our team.

About the Role:

As an AI Solutions Engineer you will sit at the intersection of cutting-edge AI infrastructure and the worlds most ambitious AI teams. You will help customers design deploy and scale modern ML and GenAI systems using Weights & Biases and CoreWeaves AI cloud. This role combines hands-on technical depth with strategic customer engagement ideal for AI practitioners who enjoy building real systems solving complex problems and shaping how AI is developed and operationalized at scale.

What Youll Do:

• Own the technical wins by building proof of value (PoVs). Youll be partnering with Account Executives to drive discovery solution design and successful technical evaluations.
• Lead deep technical conversations with ML engineers researchers and platform teams to understand their AI/GenAI workloads and architect scalable solutions across the CoreWeave and Weights & Biases ecosystem .
• Design and deliver compelling live demos proof-of-value engagements and rapid prototypes showcasing experiment tracking distributed training agentic workflows fine-tuning evaluation and inference at scale.
• Architect modern ML and GenAI systems including distributed training RAG pipelines multi-agent systems LLM fine-tuning workflows and inference solutions.
• Translate business objectives into measurable technical outcomes such as model quality improvements cost reductions performance gains and faster iteration cycles.
• Serve as a trusted technical advisor influencing architectural decisions and best practices across MLOps LLMOps and platform engineering.
• Partner closely with Product and Engineering to relay customer feedback shape roadmap priorities and improve the end-to-end AI developer experience.

Who You Are:

• 2 years of experience in Solutions Engineering ML Engineering AI Engineering or a similar customer-facing technical role.
• Strong proficiency in Python (bonus: TypeScript/JavaScript) and experience building production-grade ML or GenAI applications.
• Hands-on experience training fine-tuning evaluating debugging and deploying deep learning or LLM-based systems.
• Experience with modern GenAI architectures including retrieval-augmented generation (RAG) tool-using agents evaluation frameworks and guardrails.
• Comfortable designing cloud-native architectures across AWS GCP or Azure with working knowledge of containers networking fundamentals and security best practices.
• Able to whiteboard distributed training or inference architectures and then implement working prototypes that demonstrate real customer value.
• Excellent communication and storytelling skills with the ability to translate complex technical concepts into business impact.
• Thrives in fast-paced environments and can manage multiple customer engagements simultaneously.

Preferred:

• Experience building and evaluating agentic applications using frameworks such as LangChain DSPy LlamaIndex CrewAI OpenClaw or similar ecosystems. Ability to quickly adapt to new frameworks is a huge plus.
• Familiarity with vector databases embeddings workflows and LLM evaluation frameworks (e.g. Ragas TruLens DeepEval).
• Hands-on experience with Hugging Face Transformers PEFT/LoRA/QLoRA fine-tuning TRL Unsloth or similar fine-tuning stacks. Big plus if experience using RL to improve agentic systems.
• Experience operating distributed workloads using Slurm Ray or Kubernetes.
• Experience with inference optimization and serving frameworks such as vLLM TensorRT-LLM Triton or TGI.
• Experience in MLOps/LLMOps platform engineering or supporting enterprise AI deployments.
