We're looking for a Product Manager for Agent Builder: the core environment where agents are created, tested, and improved.
Agent Builder brings together the full agent development experience - journeys, chat, simulations, workspaces, packages, and AI copilots like Ghostwriter and Explorer - into a unified system. It reflects Sierra's Agent Development Life Cycle: Analyze 12 Build 12 Test 12 Release, repeated continuously to improve agent quality.
As PM for Agent Builder, you will define how teams actually build agents in practice. You'll shape the systems that turn ideas into working behaviors, enable rapid iteration, and allow agents to continuously improve over time.
This is a zero-to-one and scaling role at the center of Sierra's product.
What you'll do- Define the agent building experience - Shape how users move from idea 12 implementation across journeys, chat, and workflows. Create clear abstractions for building complex agent behavior without unnecessary friction.
- Own the Agent Development Life Cycle - Design how users analyze conversations, make changes, test improvements, and release updates. Ensure the loop between build 12 test 12 learn is tight, fast, and intuitive.
- Build simulation and testing systems - Define how agents are validated before deployment. Create tools for simulating real-world scenarios, identifying failures, and improving performance with confidence.
- Design reusable systems through packages - Define how integrations, skills, and agent behaviors are packaged, discovered, and reused. Enable users to compose sophisticated agents from modular building blocks that improve over time.
- Integrate AI copilots into the workflow - Work closely on how Ghostwriter (build) and Explorer (analyze) fit into Agent Builder. Decide what is automated vs user-driven, and how AI augments each step of the workflow.
- Make agent quality measurable and actionable- Define evaluation frameworks and feedback systems so users can understand performance and systematically improve their agents.
What you'll bring- 3+ years of product management experience, ideally working on developer platforms, AI systems, or complex technical products
- Strong technical depth - Ability to engage deeply with engineers on system design (e.g., simulation systems, evaluation frameworks, APIs, and platform architecture)
- Experience building 012 1 products or platforms - Comfortable defining new abstractions and workflows in ambiguous spaces
- Experience working with AI systems - Familiarity with LLMs and the challenges of building, testing, and iterating on non-deterministic systems
- Strong product instincts for builder tools - You have taste in developer experience and can balance power, flexibility, and usability
