About the Role: 

We are seeking a Senior Staff Machine Learning Engineer to define and accelerate how we leverage agentic AI to transform machine learning models and modeling workflows. This high-impact role focuses directly on  modeling leverage —enhancing model quality and velocity—rather than building general infrastructure.  As a senior staff engineer, you will operate as a technical leader across the entire modeling loop, utilizing modern AI-assisted development systems (such as Claude, Cursor, and comparable tools) to make model development faster, more rigorous, and significantly more effective across the organization.

Why Join Us? This role offers a domain-flexible platform to redefine how ML engineering is done. If you are passionate about combining deep ML fundamentals with the vanguard of agentic AI to multiply team impact, we’d love to talk to you.

What you’ll do: 

- Develop advanced ML models and the agentic workflows that help teams design, train, evaluate, and improve them.

- Use tools such as Claude, Cursor, and comparable AI-assisted development systems to investigate model behavior, generate and test hypotheses, automate repetitive analysis, and improve code and experiments.

- Build reliable loops for data and label analysis, feature and embedding development, architecture comparison, hyperparameter optimization, error analysis, and experiment readouts.

- Design evaluation harnesses that measure both model outcomes and agent/workflow quality, including correctness, reproducibility, regressions, cost, and latency.

- Partner with product, data science, ML infrastructure, and engineering teams to connect modeling improvements to user and business outcomes.

- Set technical direction across teams, mentor engineers, and raise the bar for modeling rigor and AI-assisted engineering.

Required Qualifications: 

- 9+ years of experience in ML engineering, applied ML, or a related field, with substantial production impact.

- Senior Staff-level technical leadership and a record of in…
