Job description

Adyen 25 July 2025

This is Adyen. Adyen provides payments, data, and financial products in a single solution for customers like Meta, Uber, H&M, and Microsoft - making us the financial technology platform of choice. At Adyen, everything we do is engineered for ambition. For our teams, we create an environment with opportunities for our people to succeed, backed by the culture and support to ensure they are enabled to truly own their careers. We are motivated individuals who tackle unique technical challenges at scale and solve them as a team. Together, we deliver innovative and ethical solutions that help businesses achieve their ambitions faster.

Senior Platform Engineer

We are on the lookout for a Senior Platform Engineer to join our Platform Engineering organization. Our teams in this area are responsible for provisioning, running, and managing critical data systems like PostgreSQL, Apache Cassandra, Apache Kafka, and CockroachDB for all product teams (at massive scale). Within this role you will primarily focus on one of these areas (SQL Databases Platform) or foundational components that span multiple areas. As a Platform Engineer your work will directly influence the resilience, performance, and developer experience of Adyen's core platform—a platform that processed over a trillion euros worth of payments in 2024. This role is for a versatile engineer that has a balance of engineering and infrastructure experience who is eager to deep dive into complex distributed systems and solve real‑world problems that have impact at a global scale. You will work closely with other platform teams (e.g. Databases, Containers, Networking and Storage) and product teams within Adyen to scale our data store offerings. You'll be joining a team that values user‑centric design, technical excellence, automation, continuous learning, and a proactive approach to system reliability and performance.

Responsibilities

• Design and implement: Build, maintain, and evolve the infrastructure and tooling that supports our core data platforms.
• System reliability: Ensure the high availability, performance, and scalability of our critical data systems.
• Troubleshoot and optimize: Deep dive into performance bottlenecks, identify root causes, and implement effective solutions. This includes analyzing system metrics, traces, and logs.
• Automation: Develop and maintain automation scripts and tools to streamline operational tasks and improve efficiency.
• Code and debug: Write high‑quality, maintainable code in languages such as Go or Python to solve complex engineering problems and debug existing systems.
• Collaboration: Work closely with other engineering teams to provide expert guidance and support for their data platform needs.
• On‑Call: Participate in an on‑call rotation to support the reliability of our production systems.

Qualifications

Who you are:

• Linux expert: You possess a deep understanding of Linux operating systems, including networking, file systems, and performance tuning.
• Systems engineering: Solid experience in systems engineering principles, including distributed systems, high availability, and disaster recovery.
• Coding proficiency: Strong programming skills in at least one of the following languages: Go or Python. You’re comfortable writing clean, efficient and testable code, and adept at debugging complex applications.
• Problem solver: You have a proven track record of deep diving into complex technical issues, identifying root causes and implementing robust solutions.
• Curious: You’re eager to learn new technologies and bring them to the team/company where it masks sense, dive deeper into complex systems and continuously improve your skills.
• Team player: Excellent communication and collaboration skills, with a willingness to share knowledge and contribute to a positive team environment.

You have a solid understanding of PostgreSQL or CockroachDB combined with practical experiences.

• Hands‑on experience with Kubernetes, including deploying, managing, and troubleshooting applications within a Kubernetes environment.
• Experience with other database technologies or distributed systems.
• Experience with using and deploying to OpenStack.
• Experience with Puppet, Ansible, Terraform and Vault.
• Familiarity with observability tools (e.g. Prometheus, Grafana, ELK stack).
• Experience in a fast‑paced, high‑growth environment.

Challenges you’ll tackle

The main technical challenge includes managing the complexity of large‑scale stateful database systems at global scale, where ensuring high availability, performance, and disaster recovery is top of mind. You will have to navigate high‑stakes operations (e.g., processing millions of queries per second) which can lead to issues like performance bottlenecks or failures in real‑time. You will be expected to prevent issues (be proactive), perform root‑cause analysis from metrics/logs, and do troubleshooting. Additionally, balancing deep dives into technical problems with collaboration across teams, participating in on‑call rotations, and continuously evolving infrastructure through automation and code in Go/Python.

Projects (recent/upcoming)

• Brought several new global regions live for our database platform
• Doubling our storage infrastructure footprint
• Move database primary‑failover management to use Consul DNS
• Innovation through exploring using alternative technologies e.g. NeonDb, TimescaleDb
• Postgres 17/18 Upgrade
• Build out a zero‑touch internal database‑as‑a‑service offering
• Create automation for common database pain points such as primary switches
• Expanding our Vault integrations for credentials management
• Build or adopt self‑service tools for database operations

Team structure

This role will be hired as part of our SQL Database team, part of the Persisted Data Stores group within the Platform Engineering Department of Adyen. The SQL Database team delivers and supports high‑quality SQL database experiences to Adyen developers in order to meet our merchants' expectations of reliable and accessible data. The main database they support is Postgres and CockroachDB. These datastores all run on either bare metal servers or OpenStack VM clusters that we maintain and operate.
