What You'll Do:

The AI team is a hands-on applied AI group at Weights & Biases that turns frontier research into teachable workflows. We collaborate with leading enterprises and the OSS community. We are the team that took W&B from a few hundred users to millions of users and one of the most beloved tools in the ML community. A senior applied role at the research-to-product boundary. You will design, implement, and evaluate LLM applications and agents with cutting-edge techniques from the latest research, then document and teach them to our community and customers. The focus is application, not novel research: rapid prototyping, careful evaluation, and production-grade reference implementations with clear trade-offs. We prioritize responsible, safe deployment and reproducibility.

About the role:

Ship end-to-end GenAI workflows (prompting → RAG → tools/agents → eval → serve) with reproducible repos, W&B Reports, and dashboards others can run. Build agentic systems (tool use, function calling, multi-step planners) with MCP servers/clients and secure tool/resource integrations. Design evaluation harnesses (RAG/agent evals, golden sets, regression tests, telemetry) and drive continuous improvement via offline + online metrics.

Build in public:

Publish engineering artifacts (code, docs, talks, tutorials) and engage with OSS and customer engineers; turn repeated patterns into reusable templates. Partner with product/solutions to launch LLM-powered features with clear latency/cost/SLO targets and safety/guardrail checks. Run growth experiments to track the usage of the Weights & Biases suite of products from the artifacts built.

Who You Are:

Software engineering: 6+ years building production systems; strong Python or TypeScript + system design, testing, CI/CD, observability.

GenAI apps:

shipped LLM-powered features (tools/agents/function calling), with measurable impact (latency/cost/reliability).

Agentic patterns:

implemented planners/executors, tool orchestration, sandboxing, and failure taxonomies; familiarity with agent infra concerns.

RAG:

pragmatic mastery of chunking, embeddings, vector/hybrid search, rerankers; experience with vector DBs/search indices and retrieval policy design.

Evaluation:

designed LLM/RAG/agent evals (offline golden sets, counterfactuals, user studies, guardrail tests); stats literacy (variance, CIs, power). Serving & productization: comfortable with queueing, caching, streaming, and cost controls; can debug latency at model, retrieval, and network layers.

Public signal:

2+ substantial OSS repos/blog posts/talks/videos with adoption (stars, forks, downloads, views) and reproducible artifacts.

Preferred:

Experience building with AI SDKs / agent frameworks (e.g., TypeScript/Python SDKs, planning libraries) and shipping developer-facing examples. Production agent security/sandboxing, red-teaming, and policy/PII enforcement. Operated eval platforms or built judge models/heuristics; experience leading metrics reviews with product/UX.

Customer-facing enablement:

templates or reference implementations adopted by external teams at scale. Wondering if you're a good fit? We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams

• even if you aren't a 100% skill or experience match.

Here are a few qualities we've found compatible with our team. If some of this describes you, we'd love to talk. You love turning ambiguous product ideas into clean, benchmarked, production-ready LLM/agent workflows others can use today. You're curious about the latest research from AI labs and excited to apply it to real-world problems. You're an expert in at least one of: RAG quality at scale, agent/tool orchestration, or GenAI DX (SDKs, examples, docs)—and you can demonstrate it with code and metrics. Why Us?

Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file. As set forth in CoreWeave's Equal Employment Opportunity policy, we do not discriminate on the basis of any protected group status under any applicable law. Gender Select... Are you Hispanic/Latino? Select... Race & Ethnicity Definitions If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows: A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability. A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service. An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense. An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985. Veteran Status Select... Voluntary Self-Identification of Disability Form CC-305 Page 1 of 1 OMB Control Number 1250-0005 Expires 04/30/2026 Why are you being asked to complete this form? We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years. Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor's Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp . How do you know if you have a disability? A disability is a condition that substantially limits one or more of your "major life activities." If you have or have ever had such a condition, you are a person with a disability.
