More about our mission and what we offer.

About the role:

We are looking for a Database Reliability Engineer with a passion for PostgreSQL and a drive to maintain business-critical systems at scale. As part of the Database Reliability Engineering (DBRE) team, you will be a core owner of the Wise database estate, which underpins every transaction and customer experience.

Your mission will be to empower Wise's growth by engineering reliable, scalable, and performant database solutions. You'll collaborate closely with the Database Platform and Product Engineering teams, applying sound engineering principles to automate and enhance our database infrastructure (PostgreSQL, MariaDB, MongoDB, Redis/Valkey). A key part of your role will be establishing best practices and building the guardrails that keep our customers data safe.

Who we are looking for

We're looking for a passionate engineer with a strong platform engineering mindset. While we value a balance between deep database knowledge and robust engineering skills, don't be intimidated. If you are strong in one area and eager to learn the other, we encourage you to apply.

Professional Experience:

• Proven experience managing large-scale, highly available PostgreSQL deployments in a 24/7 production environment. 

• A proactive approach to system reliability, observability, and capacity planning

Database Skills:

• Deep understanding of PostgreSQL internals, replication, and performance tuning.

• Demonstrable expertise in database administration, security, and reliability best practices. 

• Exposure to distributed database technologies (e.g. YugabyteDB, CockroachDB, TiDB) is a significant plus.

Engineering Skills:

• An automation-first mindset; you'd rather script a solution than repeat a manual task.

• Experience with Infrastructure as Code (IaC) using tools like Terraform or Ansible.

• Proficiency in a major cloud platform (AWS or GCP), including their services and APIs.

• Experience with scripting or software development in languages like Python or Go.

Nice to have:

• Experience working with Redis/Valkey, MongoDB and/or MariaDB/MySQL.

• Experience in building self-service tooling that helps engineers, analysts or data scientists do their job more efficiently.

• Knowledge/interest in payment platforms, foreign exchange & highly complex systems

• Be a customer of Wise.
