What you'll do
We are looking for a PostgreSQL Database Administrator to join the Database Optimization team within our Platform team!
The Database Optimization team ensures the reliability and performance of our datastores while fostering a platform mindset in our transition to the "you build it, you run it" paradigm. It is a multidisciplinary team made of both Site Reliability Engineers and Software Engineers, which enables us to have a complete view of the problems we need to solve and of the alternative solutions we might implement to solve them.
As a PostgreSQL Database Administrator (DBA), you will play a critical role in our mission for our main datastores: PostgreSQL / AWS Aurora, Kafka, Couchbase and OpenSearch. You'll ensure high availability while empowering feature teams with the tools and expertise they need to succeed!
Your responsibilities include but are not limited to:
- Reliability Engineering: Ensure high availability of our datastores and our own operational efficiency through observability, automation, tooling, backup strategies, disaster recovery planning and process improvement

- Have hands-on experience with Kafka or an equivalent technology
- Have hands-on experience with Infrastructure as Code (Terraform), containerization technologies (Docker, Kubernetes), and cloud environments (AWS, Azure or Google Cloud) in a production environment
- Have excellent communication and mentoring skills and embrace the "you build it, you run it" philosophy
Now, it would be fantastic if you:
- Have experience with multiple kinds of datastores and have curiosity and willingness to learn new datastores and adapt to evolving technology landscapes
- Have been involved in architecture choices for high traffic web applications, particularly scalability challenges on large databases, and building self-service services through Database as a Product approaches
- Are comfortable with Linux systems administration, automation, and performance troubleshooting
- Speak English fluently
