Senior Software Engineer - Customer Interfaces

Full-Stack Technical Depth:

Deeply proficient in Java for high-concurrency backend services, with architectural competence to integrate and support Agentic workflows (Python).

Experienced with Vue/Preact for complex, stateful web applications.

Hands-on experience (or strong architectural competence) with production-grade Agentic AI integrations, including policy layers, evaluation frameworks, RAG architectures, and deterministic execution boundaries.

Security-First Mindset:

A "security-by-design" approach to handling sensitive financial data, user authorization, and zero-trust access in web environments.

As a Senior Full Stack Engineer for Customer Interfaces in San Francisco, you will lead the evolution of Adyen’s experience platform, building the foundational frameworks, AI-integrated guardrails, and component libraries that empower global teams to ship secure, conversational financial experiences.

We are looking for a product-minded engineer who can build end-to-end streaming, multi-modal user interfaces while architecting backend agentic workflows (specifically Tool-use, Chains, and Policy Layers).

In this role, AI is not a standalone job title or a hypothetical sandbox; it is an integrated engineering capability used to transform natural language inputs into authenticated, secure financial operations.
