Research Scientist, Agent Reasoning San Francisco $260,000 - $340,000

About the role

Pazau Agent 3 plans multi-step work: it checks eligibility, calls three systems, asks for approval and then confirms with the customer, all while following a Procedure a CX manager wrote in plain English. We don't train foundation models on customer data, so our research focuses on the layer above them: planning, tool use, policy adherence and knowing when to hand off.

The base salary range for this role is $260,000 – $340,000 . Final offers depend on level and location, and every offer includes equity.

What you'll do

• Research methods that improve Procedure adherence and Action accuracy without customer-data training


• Design reasoning strategies for long, multi-turn conversations where the customer changes their mind halfway through


• Build calibrated confidence signals that decide when the agent acts, asks for approval or escalates to a human


• Work with the Evaluation team to turn research wins into shipped improvements, measured in customer resolution rates

What you'll bring

• A PhD or equivalent research experience in machine learning, NLP or a related field


• A track record of research on LLM agents, planning, tool use or reasoning


• Strong engineering skills. You'll prototype in Python and ship alongside production engineers


• Interest in problems where being right 97% of the time is not good enough

Nice to have

• Publications at NeurIPS, ICML, ACL or similar


• Experience with RL from environment feedback or simulation-based training

• Medical, dental and vision for you and your dependents, with 100% of premiums covered


• Equity in Pazau, with a 10-year exercise window after you leave


• 16 weeks of fully paid parental leave for every parent


• 401(k) with a 4% match


• $2,000 a year for learning, plus conference travel when you're speaking


• Four weeks of paid time off, plus a company-wide week off at the end of December


• Recruiter call (30 min). We walk through the role, compensation and timeline, and answer your questions first.


• Hiring manager conversation (45 min). A conversation about work you're proud of and the problems this team owns.


• Research talk (60 min). You'll present your past work to the AI team, followed by a technical discussion.


• Final interviews (3–4 hours, virtual or on-site). Three or four conversations with the people you'd work with every day, including one cross-functional partner.


• Founder conversation and references. A 30-minute conversation with Amara or Lukas, then two references you choose.
