Senior AI Engineer

We are looking for a Senior AI Engineer to join our AML (Anti-Money Laundering) Tech team in Amsterdam. You will help build our next-generation financial crime investigation system, leveraging AI to manage and mitigate risk at scale. With our global footprint, you will have access to a uniquely rich dataset to fuel these solutions.

You will bridge the gap between applied research and engineering excellence, taking ownership of the end-to-end lifecycle of these AI systems – from initial ideation to production. We are building a Human-in-the-Loop system. By evolving our capabilities from isolated workflows to a highly performant, trustworthy agentic system, you will shape how humans and AI collaborate in a complex, regulated domain.

This is a unique opportunity to be part of the foundational group driving AI product development at Adyen. You will be building zero-to-one products, setting the architectural standards for our team, and defining how AI is practically deployed across the company.

In this role, you will:

Build Agentic Systems: You will lead the design and deployment of robust, multi-step AI agents tailored for complex investigation workflows (orchestration, tool dispatching, state and memory management, error recovery, human-in-the-loop design).
Develop Platform Infrastructure: You will build a scalable modular agent platform that seamlessly integrates with enterprise data to support Adyen’s massive operational scale and diverse use cases.
Architect Evaluation Frameworks: You will design custom, domain-specific benchmarks and reusable infrastructure to rigorously test LLM reliability, edge cases, failure modes, and overall production readiness.
Provide Strategic Leadership: You will act as the leading engineer for the team, driving the AI product roadmap in close collaboration with a high-performing product team and leadership, guide company-wide MLOps decisions, evaluate third-party tools, and lead cross-functional integration.

Who You Are

Experienced Builder: 5+ years in Software or Machine Learning Engineering, including 2+ years successfully designing and productionizing AI systems.
Agentic Architecture Expert: Proven experience in applied AI, with a focus on building systems around pre-trained models (e.g., context engineering, fine-tuning, RAG, inference optimization, orchestrating model interactions with external tools to deliver solutions, multi-step tasks). You know exactly what separates a research prototype from a production agent.
Engineering & MLOps Pragmatist: Highly proficient in Python with a strong grasp of engineering best practices and tracking "LLM-native" metrics (e.g., granular tracing, tokens/sec, cost-per-request).
Proactive Leader: A self-starter who thrives in ambiguity, continuously raises the technical bar, influences system architecture, and mentors the team to build for scale.
Educated: Master’s degree in a STEM field (Science, Technology, Engineering, Mathematics) or equivalent technical background.
Bonus (Nice to Have): A strong foundation in traditional Machine Learning. You understand that this product sits within a broader ML ecosystem and pragmatically choose the right tool for the problem.
