This is a deeply product-driven role. Success is measured by real customer impact - better expense documentation, stronger policy compliance, and less time spent navigating Brex - not by novelty or research output.
Where you'll work
Lead and grow a team of engineers building the end-to-end conversational experience for the Brex Assistant, including outbound system-initiated interactions and inbound chat.
Operate at all levels, guiding your team through complex technical challenges while being hands on with code and contributing to design.
Own delivery and outcomes for the Assistant roadmap, making and executing hard sequencing decisions for agent capabilities (e.g., memory, preferences, merchant data).
Set and uphold a high bar for reliability, correctness, and UX in non-deterministic, agentic systems operating in real-world financial workflows.
Partner closely with Product, Design, and adjacent engineering teams (Spend, Expense, Platform) to shape direction and integrate deeply with core Brex workflows.
Establish strong team norms and execution standards, balancing velocity with validation, quality control, and operational excellence.
Requirements
Proven experience leading engineering teams building user-facing products in complex, real-world domains.
Strong product judgment, with a track record of making hard tradeoffs and delivering outcomes under real constraints.
Experience building and operating systems that must remain reliable despite messy inputs, ambiguity, or non-deterministic behavior.
Ability to translate high-level product goals into clear technical direction and execution plans, while mentoring engineers through strong technical and product guidance.
Bonus points
Development experience with Typescript while leading consumer-facing AI products, especially in regulated or high-stakes domains (finance, healthcare, travel).
Direct experience with conversational UX, agents, or other non-deterministic systems in production.
Prior experience as a tech lead for agentic systems, particularly in spend or financial workflows.
Personal empathy for spend-heavy workflows (frequent travel, recruiting, managing expenses on behalf of a company).
