Requirements

You think in terms of user outcomes. You have a track record of partnering with product teams to turn ambiguous goals into robust technical reality.
You have experience (or a deep technical interest) in building production-grade interfaces powered by LLMs, including harnesses, policy enforcement, evals, RAG architectures and secure data handling.
Deeply proficient in Java for secure backend services and TypeScript/React/Vue for complex front-end applications.
You have a "security-by-design" mindset, particularly regarding the handling of sensitive financial data in modern web environments.
You will be a core member of our growing San Francisco team, where you will be expected to operate with speed and autonomy. Success in this role requires you to effectively navigate and collaborate with a large, global organization.
You must be work authorized in the United States without the need for new visa sponsorship. The company can support visa transfers but will not sponsor individuals for H-1B CAP applications.

Responsibilities

Lead the next generation of conversational UIs at Adyen. You will build Generative UIs that adapt in real-time, moving beyond static dashboards to create streaming, multi-modal experiences where the interface itself is a dynamic partner in the conversation.
Act as the primary technical liaison for AI initiatives, coordinating their integration and ensuring operational excellence with teams in different areas and global geographies. You will ensure that "intelligent modules" built in are the gold standard for performance and extensibility.
Architect the security layer for conversational interfaces. You will solve the unique challenge of maintaining strict financial data privacy and "Zero Trust" principles while leveraging LLMs and advanced data processing.
Partner deeply with the Head of Product to identify high-impact flows. You aren't just implementing designs; you are identifying where intelligent automation can solve "impossible" merchant problems.
Own the end-to-end technical lifecycle. From backend services and data pipelines that feed our insights, to the frontend components that render them.
Mentor engineers and coordinate with global hubs to drive technical standards that benefit the entire Adyen ecosystem.
