## Description

We seek an experienced, passionate, and resourceful Senior Staff Software Engineer to join our product engineering team. You will work cross-functionally with various teams and contribute to designing and developing our core products. The Mountain View base salary range for this full-time position is $279,000-$341,00-00, plus equity and benefits. We determine salary ranges by role, level, and location. This hybrid position in Mountain View requires 2 days of in-office work per week., * Own architecture that spans business units: define domain boundaries, decide where cross-cutting concerns belong, and keep product logic, policy, and funds flow in the right layers.

 * Lead design and architecture reviews across BUs, and record decisions in clear, durable architecture decision records.
 * Drive decomposition and unification roadmaps for shared systems, including how user state is split across domains, and sequence the work so teams can adopt it incrementally.
 * Prevent accumulated complexity by making deprecation, experiment cleanup, and clear ownership part of the design, not an afterthought.
 * Partner with Platform, Money Platform, and BU engineering leads so standards are practical, adopted, and not duplicated.
 * Use AI tools daily for design exploration, code analysis, and review, and build the agents, skills, and documentation that make our architecture legible to both engineers and AI coding agents.
 * Set the bar for responsible AI-assisted development: guardrails, review practices, and patterns that keep AI-generated code consistent with our architecture.
 * Mentor Staff and Senior engineers through design reviews, code, and architecture guidance, and help raise the technical bar across teams.
 * Contribute to hiring and onboarding, and represent engineering in technical discussions with product, risk, and leadership.
