Software Engineer

We’re looking for a versatile Software Engineer to join our Platform Engineering organization and help shape the resilience, performance, and developer experience of Adyen’s database platform. In 2026, this platform supports payments and money movement totaling over a trillion euros - the work you do will have a real, high-stakes impact.

You'll join the SQL Databases Enablement Team, whose mission is to improve the efficiency of the SQL Databases Teams as well as to enable the autonomy of the database owners while maintaining data durability and database uptime. We are responsible for providing better insight into databases, the release tools to manage schema changes safely, as well as the extension of databases both to new DCs and existing ones as well as deployment to bare metal and OpenStack, and various additional tools automated and semi-automated. You’ll work across networking, compute, and storage, designing systems that detect failures and recover automatically with minimal downtime.

What you’ll do:

• Build the Platform: Design and develop tooling and services in languages like Java, Python, Go or Rust. We also widely use ansible and puppet.
• Automate: Identify opportunities to migrate manual tasks to semi- or full automation.
• Deep Dive & Debug: Investigate complex performance bottlenecks at the kernel, network, or database level. You will analyze system metrics, traces, and logs to identify root causes in a distributed environment.
• Developer Experience: Treat our internal product teams as your customers. You will build tooling that abstracts the complexity of large-scale stateful systems, allowing product engineers to focus on business logic.
• Operational Excellence: Participate in the on-call rotation, not just to fix fires, but to learn from them and remove/reduce the toil.

Who you are:

• A Systems Thinker: You have a deep understanding of Linux (networking, file systems, kernel tuning) and distributed systems principles. You understand what happens when a stateful service fails in a distributed environment.
• A Software Engineer: You are proficient in Python, Java or Go. You don’t just write scripts, you write clean, testable, maintainable code to build infrastructure automation and internal tools.
• A Database Enthusiast: You understand the operational challenges of running databases (PostgreSQL, or similar) at scale.
• Problem Solver: You are proactive. You prefer performing root-cause analysis and building permanent fixes over applying temporary patches.
• Collaborative: You can communicate complex infrastructure concepts to application engineers and work closely with Compute, Networking, and Storage teams.

Bonus points for:

• Internal knowledge of PostgreSQL.
• Experience operating OpenStack or managing Bare Metal fleets.
• Familiarity with Infrastructure-as-Code (Terraform, Ansible, Puppet) and Secret Management (Vault).
• Experience with observability at scale (Prometheus, Grafana, ELK).
