We’re looking for a Product Manager for Ghostwriter: the agent-building agent.

Ghostwriter transforms how software is built. Instead of navigating tools, users simply describe what they want, and Ghostwriter creates and deploys fully functional AI agents across channels like chat, voice, and email.

As PM for Ghostwriter, you will define how humans interact with software in the agent era. You’ll own the end-to-end product experience from prompt to agent to outcome and help scale Sierra to thousands of customers.

This is a zero-to-one and one-to-many role at the same time.

• Define how AI augments agent development - shape the workflows by which CX teams and developers draft journeys, run simulations, analyze conversations, and improve agents using natural language.
• Balance autonomy and control - design the right human-in-the-loop patterns (approval flows, change review, workspace isolation) so customers trust Ghostwriter to make meaningful changes to their agents.
• Partner deeply with AI/ML and platform engineering - collaborate on model selection, harness engineering, execution architecture, and evaluation/testing infrastructure.
• Be the voice of the agent builder - deeply understand the pain points of CX managers, agent developers, and technical teams configuring journeys, integrations, and simulations.

• 3+ years of product management experience, with meaningful time working with large language models directly.
• Experience shipping AI products at the frontier - you deeply understand frontier model capabilities and limitations, evaluation challenges, and the unique UX considerations of non-deterministic systems.
• Track record of 0 to 1 product development - you have taken an early-stage product and driven it to broad adoption; comfortable with high ambiguity and rapid iteration.
• Strong technical depth - ability to engage meaningfully with engineers on architecture decisions (e.g., harness design and engineering, workspace isolation, API design).

• Trust:
  We build trust with our customers with our accountability, empathy, quality, and responsiveness. We build trust in AI by making it more accessible, safe, and useful. We build trust with each other by showing up for each other professionally and personally, creating an environment that enables all of us to do our best work.
• Customer Obsession:
  We deeply understand our customers’s business goals and relentlessly focus on driving outcomes, not just technical milestones. Everyone at the company knows and spends time with our customers. When our customer is having an issue, we drop everything and fix it.
• Craftsmanship:
  We get the details right, from the words on the page to the system architecture. We have good taste. When we notice something isn’t right, we take the time to fix it. We are proud of the products we produce. We continuously self-reflect to continuously self-improve.
• Intensity:
  We know we don’t have the luxury of patience. We…
