Founded in 2009, Unlimit operates across 17 global offices with 700+ experts, seamlessly integrating 1,000+ payment methods into a single platform. From London to São Paulo, we empower businesses to scale across borders with a unified suite of financial tools — including payment processing, alternative payment methods, multicurrency business accounts, card issuing, banking‑as‑a‑service, and crypto on‑and off‑ramps.

Our mission is to break down financial barriers and enable seamless money movement across borders. We give forward‑thinking businesses the tools to accept, send, and manage payments effortlessly, wherever they operate.

• define standards and best practices,
• build observability and reliability into the platform by default,
• mentor and guide DBAs and engineers,
• prepare the data platform to support future AI‑driven services.

  DB, Mongo
  
  DB).
• Assess the current database landscape, identify bottlenecks, and drive improvements.
• Design and maintain HA/DR architectures with clear RPO/RTO and PITR strategies.
• Build and standardize monitoring, alerting, and performance visibility.
• Enable self‑service, automation, and Git Ops‑driven database operations.
• Define security and governance standards (encryption, access models, auditing).
• Reduce operational “monkey jobs” through automation and AI‑assisted tooling.
• Mentor DBAs and collaborate closely with engineering, SRE, and product teams.
• Drive the platform toward 99.95%+ availability
  .

• 5+ years of experience in database engineering or administration, including leadership responsibilities.
• Strong hands‑on expertise in PostgreSQL (replication, partitioning, performance tuning, PgBouncer/RDS Proxy, vacuum strategies, pgvector).
• Solid experience with Oracle (backup/restore, AWR/ASH, Data Guard or equivalents).
• Production experience with AWS data services (Aurora, RDS, Document
  
  DB, Mongo
  
  DB).
• Proven HA/DR and PITR implementation experience.
• Experience operating high‑load, transactional systems.
• Strong understanding of database security and governance (encryption, IAM, RLS/VPD, secrets management).
• Experience with Infrastructure as Code and automation (Terraform, Git Ops).

• Multi‑region or global database topologies (Aurora Global, cross‑region replication).
• CDC and migration tooling (AWS DMS, Debezium).
• Cost optimization and capacity planning experience.
