About Stripe

Stripe is a financial infrastructure platform for businesses. Millions of companiesfrom the worlds largest enterprises to the most ambitious startupsuse Stripe to accept payments, grow their revenue, and accelerate new business opportunities.

That means you have an unprecedented opportunity to put the global economy within everyones reach while doing the most important work of your career.

About the team

The User Auth Experience (UAX) team makes authentication and account security at Stripe world-classsecure by default, frictionless for legitimate users, and resilient against evolving threats. We own the end-to-end login, registration, and session management experience for the Stripe Dashboard, and we're expanding that security foundation to every surface where users and agents interact with Stripe.

We improve security, access, and usability simultaneouslywithout compromising any of the three. Our scope spans account takeover prevention, API key security, auth for AI agents, and a two-party approvals framework governing both human and automated actions.

The team sits within OAP (Organizations and Auth Platform) in the DEeP (Developer Experience and Product Platform Engineering) organization at Stripe.

What youll do

As a Staff Engineer on UAX, you'll set technical direction across multiple areas of the team's charter, drive architecture decisions that affect millions of users, and lead initiatives that span multiple organizations. You'll operate at the intersection of security and productdesigning systems where the safe path is the default path, and navigating the tension between stronger security and lower user friction.

You'll own the technical vision for one or more of our platform betsextending our risk-scoring framework from login to API-layer anomaly detection, evolving our step-up challenge platform to serve multiple Stripe surfaces, or defining Stripe auth primitives for the agentic era (agent principals, approval rules, MCP human-in-the-loop). These are multi-year arcs that require someone who can hold the long-term architecture while shipping incrementally.

You'll also directly build risk-dynamic enforcement pipelines, full-stack approval flows, API key protection UX, and the analytics infrastructure that measures our impact. This is a hands-on role with architectural leverageyou'll write code, review designs, and shape how partner teams integrate with our security primitives

Responsibilities

• Own the technical architecture for a major area of the team's charter
• Design and ship systems that serve multiple Stripe surfacesbuilding generalized primitives, not point solutions
• Drive cross-org technical alignment on shared security infrastructure
• Make effective tradeoffs that consider security posture, user friction, and sustainable technical foundations
• Mentor and grow engineers on the team
• Raise the bar for design rigor, operational excellence, and code quality
• Shape the team's multi-year roadmap through technical foresight and principled prioritization

• Experience building risk-based or adaptive security systems (anomaly detection, step-up auth, fraud prevention)
• Strong understanding of IAM concepts, including RBAC, identity governance, SCIM, delegated auth, or approval workflows
• Experience defining auth or security primitives for programmatic consumers (APIs, agents, and SDKs)not just human-facing UI
• Experience building scalable, resilient, and observable systems while understanding UX best practices for the frontend
