We are seeking a highly skilled and proactive Staff Engineer with a strong background in Java Software Engineering and hands-on experience in technical system design. In this role, you will play a critical part in designing, building, and scaling systems to solve real-world business challenges.

You are someone who is curious about new technologies, eager to learn, and passionate about using technology as a practical tool to drive meaningful business impact. You enjoy solving complex problems and thrive in environments where innovation, continuous learning, and collaboration are key.

What you’ll do

• Own technical leadership for critical money flows across settlement models, reconciliation pipelines, and accounting/ledger interfaces - taking initiatives from problem framing through delivery and long-term operation.
• Design and build robust, scalable systems in production, improving reliability, performance, and operability of the settlement platform.
• Engineer for correctness and resilience by default: idempotency, retries, recovery, backfills, data repair tooling, and safe rollout strategies; measurably reduce incident frequency and time-to-recovery.
• Lead architecture and technical decision-making: drive design docs and design reviews, align teams on shared patterns and invariants, and communicate trade-offs clearly to technical and non-technical stakeholders.
• Partner cross-functionally with Product, Finance, Data, Risk/Compliance, Operations, and Account Management to translate business and regulatory needs into pragmatic technical solutions.
• Improve platform boundaries and developer velocity by simplifying interfaces, reducing coupling, and clarifying domain ownership - making the system easier to evolve safely.
• Raise the engineering bar through strong practices in observability, testing strategy, documentation, and operational playbooks.
• Mentor and multiply impact via coaching, code reviews, knowledge sharing, and enabling teams to make high-quality decisions without becoming dependent on you.
• Support hiring and talent growth: help define role needs, participate in interviews, and contribute to building a strong, inclusive engineering culture aligned with Adyen values.

Who you are

• You have at least 10-12 years of extensive industry experience in Software Engineering, including hands-on experience in system design, architecture, and development with technologies such as Java, Postgres, Kafka, RabbitMQ, and Redis.
• You think strategically, are able to connect business goals with technical execution, and design systems that scale with the company.
• You’re proactive and self-driven, with a natural ability to identify what needs to be done, even in unstructured environments, through collaboration and critical thinking.
• You’re energized by complexity and curious about the mechanics of financial systems.
• You are able to challenge constructively, foster collaboration, and drive engagement.
• You come from a high-paced, product-oriented environment.
• You’re a clear communicator and influencer in English, comfortable navigating cross-functional dynamics and driving alignment.
• A pragmatic mindset on engineering quality: testing, observability, documentation, and operational readiness are part of the design.
• A multiplier approach to leadership: you elevate others without becoming the bottleneck.
