Staff AI Product Manager

• The Product team is at the forefront of Brex’s mission to empower employees anywhere to make better financial decisions. With a deep understanding of the business, we identify and scope out the most impactful opportunities for Brex to tackle. We are responsible for aligning cross-functional teams — such as Engineering, Legal, Compliance, and Design — on key decisions. We set strategy and drive products from inception to launch, enabling Brex to grow rapidly and help our customers reach their full potential
• The Brex Assistant is an AI agent that acts as an executive assistant for every employee — handling the expense, spend, and travel busywork they’d otherwise do by hand, and meeting them where they already are, in chat and over SMS. No app to open, no form to fill; the agent understands what you need and takes real actions on your behalf, in a conversation
• You’ll own the Brex Assistant end to end — a product that can touch every Brex cardholder, yours to shape top to bottom. You’ll set the product direction and strategy, decide which capabilities to build and how they should behave, and talk to users constantly to figure out what will actually help them
• From there you go as deep as it takes to make it real — shaping the agent’s behavior, writing and iterating prompts, designing the evals that prove it works, and digging into traces when it breaks. You’ll partner closely with engineering, design, and research, and you’ll set the quality bar for an agent that real people trust with real money
• Own product direction for the Brex Assistant — the strategy, the roadmap, and the day-to-day calls on what ships
• Define agent capabilities that take real actions for users, and translate messy real-world expense and spend workflows into reliable agent behaviors
• Invent the “how”: design the evals, prompting approaches, and feedback loops that make the agent dependable — and re-invent them as the underlying models and tooling shift
• Get hands-on. Prototype, measure, read transcripts, and iterate quickly toward what actually works rather than what looks good in a demo
• Talk to users constantly, and let real usage — not assumptions — drive the next iteration
• Set and defend a high quality bar for an agent operating in a trust-critical, financial context

You’ve owned something early-stage or taken a problem area and run with it on your own initiative (as a founder, an early operator, or an early or only PM on a surface), working closely with engineering and design rather than in isolation
• You move fast and go deep — comfortable prototyping, reading data, and getting into the details rather than working through layers
• You’ve built AI products for other people. You’ve shipped LLM/agent features to real users and have genuine, hands-on depth in prompting, eval design, and iterating against measurement — not just using AI tools in your own day-to-day
• Strong product taste and judgment about what’s worth shipping to customers and what isn’t
• You’re an experienced product manager (7-12 years of relevant experience). You have a track record of owning complex, user-facing products end to end — setting direction and shipping to real users — with the scope and judgment this senior role calls for
• Experience building conversational, chat-native, or SMS-based products; familiarity with fintech, expense management, or spend workflows
