Who you are:

• You have a sustained track record of turning research into agent capabilities that ship, and you think beyond the immediate task to understand why it matters.
• You are a driver. You can scope a six-week delivery cycle (our current shipping cadence, matching the wider product organization), keep it moving, and know when shipping fast would compromise the quality of what goes out.
• You have a strong sense of data and model intuition. At our scale, and in a fast-moving agentic space, off-the-shelf approaches often do not hold up, so you can work from first principles to build evaluation, guardrails, and optimization that fit our systems.
• You have a product-focused and start-up mindset and enjoy moving quickly on innovative product ideas, not just the technical problems underneath them.
• You mentor by doing. You guide and teach, bringing others along with you.
• You have a habit of guiding AI-assisted development. You know the difference between blindly accepting what a model produces, refusing to use it at all, and guiding it to the right answer, and you consistently do the last of these.

What You Bring to the Table:

• An abundance of intellectual curiosity, and enthusiasm to learn and teach new techniques as agentic AI keeps changing.
• Comfort working on an agile, distributed team spanning multiple time zones, and the ability to communicate clearly across technical and non-technical audiences.
• 5+ years of experience (or 3+ with a PhD) in a data-driven or applied ML role, including leading technical projects end-to-end. An advanced degree in a quantitative field is useful but not required. What you can contribute matters more than how you got here.
• Hands-on experience with Python and a deep learning framework such as PyTorch, including training or fine-tuning models through approaches such as supervised fine-tuning or preference optimization (e.g., DPO).
• Experience with Databricks, Spark, Delta Lake, and Unity Catalog, strong SQL, and experience tracking experiments and models with MLflow or a similar tool.
• Experience serving models in production (for example vLLM or Ray Serve) and building or orchestrating agents with frameworks such as LangGraph, DSPy, or MCP-based tooling.
• Comfort writing production-quality, reviewable code, and working with confidence and without ego: you have strongly held, defensible ideas, and you are quick to help a teammate when something breaks.
• A commitment to valuing, seeking out, and fostering diversity of background and perspective on your team.
• You have a track record of turning recent agent or LLM research into solutions for real, messy problems, not just benchmarks.
• You have experience building evaluation harnesses, benchmark datasets, or scenario-driven testing for LLM-based systems.
• You have experience with routing, prompt optimization, or memory systems for agents operating at scale.
• You have hands-on experience with guardrail or safety systems for AI-facing products, for example Llama Guard, NeMo Guardrails, or similar frameworks.
• You have experience with orchestration or workflow tooling such as Ray, Airflow, or Dagster for production data and training pipelines.
