AI Engineer- Gen AI/SWE- Weights & Biases

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 engin
