You'll help modernise existing systems while balancing reliability, correctness, and change, making architectural decisions that directly affect uptime and merchant experience across multiple markets.

Our tech stack includes Go, AWS, Kafka, PostgreSQL, and Kubernetes, supported by a strong observability toolchain with Prometheus, Grafana, and Honeycomb. We also actively use AI‑assisted development tools such as Cursor, GitHub Copilot, and others.

• Support the operation of the systems you work on by participating in on‑call rotations, incident response, and learning from post‑incident reviews.
• Apply a backend and systems perspective during refinement, raising questions about risks, dependencies, and edge cases.
• Collaborate closely with Product, QA, and other engineers to deliver end‑to‑end transfer and banking capabilities.
