Senior Database Reliability Engineer

- Are you curious, excited by experimentation and always looking to innovate?

- Do you want to work in embedded payments where you can keep learning and developing whilst getting hands-on experience?

- Do you want to have the opportunity to play an important role in a rapidly growing and exciting Fintech business?

If so, we would love to connect and collaborate!

Modulr is a B2B embedded-payments platform operating at scale in a regulated environment. As we evolve our core data architecture, we’re hiring our first dedicated Database Reliability Engineer to raise the operational resilience of our payments platform.

This is a hands-on role for someone who thinks like a Site Reliability Engineer but has deep database expertise — someone who wants to make a large, busy production estate observable, diagnosable, and safe to operate, and to be the database voice that shapes how we scale. It carries a clear path toward a data-architecture mandate as the platform matures.

- Own the reliability, performance, and observability of our production databases (primarily PostgreSQL / Amazon Aurora), so that issues are seen and understood in minutes, not hours.

- Lead deep-dive diagnosis of production incidents — query performance, lock and wait-event analysis, connection-pool behaviour, blocking sessions — and turn findings into lasting fixes and runbooks.

- Build proactive guardrails: query and statement timeouts, connection-pool standards, slow-query and contention alerting, capacity and saturation monitoring.

- Partner with engineering squads to design schemas, indexes, and access patterns that scale, and to enforce safe database practices in their services.

- Contribute the database-reliability perspective to significant platform-evolution work, including separation of read and write paths and the decomposition of shared database components.

- Improve our database observability tooling and dashboards so reliability is measurable and trends are visible before they become incidents.

- Help embed a culture of operational excellence, blameless post-incident review, and continuous improvement.
