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.

• 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.
