About the role

Key responsibilities & impact
  • Design, build, and maintain backend microservices in Go and Java/Quarkus within our domain-oriented architecture (customer, account, transactional, and shared domains).
  • Own services end-to-end: architecture, implementation, testing, deployment to QA/SBX/PROD, monitoring, and on-call ownership of what you ship.
  • Build event-driven and REST integrations across services (Pub/Sub, service-to-service REST via our private-proxy mesh), with strong guarantees around idempotency, reconciliation, and failure handling (dead-letter/reprocess, no silent data loss).
  • Model and evolve data across MongoDB and SingleStore/MemSQL, keeping dual-write flows consistent between the display source of truth and what card authorization actually validates.
  • Ship through our CI/CD (Jenkins shared pipelines, containerized deploys to GKE/Kubernetes on GCP), managing configuration and secrets via GCP Secret Manager.
  • Write clean, self-documenting, well-tested code; participate in code reviews and raise the engineering bar for correctness and simplicity.
  • Collaborate cross-functionally with Product, Infra/Platform, and other backend squads to break down epics into shippable, incremental deliveries.
  • Instrument observability (structured logging, metrics, tracing) and use it to debug production issues and continuously improve reliability and performance.
  • Contribute to technical design docs, architecture diagrams, and shared conventions/scaffolding that scale the team.

Requirements

What you’ll need
  • Bachelor's degree in Computer Science, Software Engineering, or related field (or equivalent hands-on experience).
  • +5 years of experience building and operating backend services in production, ideally in the Banking or Fintech industry.
  • Strong proficiency in at least one of Go or Java (Quarkus/Spring or similar), and willingness to work across both in a polyglot environment.
  • Solid experience with microservices and distributed systems: REST APIs, asynchronous/event-driven messaging (Pub/Sub, Kafka, or similar), service boundaries, and versioned contracts.
  • Hands-on experience with cloud infrastructure (GCP preferred), containers and Kubernetes, and CI/CD pipelines.
  • Comfort with both SQL and NoSQL data stores (MongoDB, SingleStore/MySQL/Postgres) and an eye for data consistency in money-critical flows.
  • Deep understanding of reliability patterns — idempotency, retries, reconciliation, graceful degradation — and why they matter when handling real money.
  • Familiarity with fintech/payments concepts (card authorization, ledgers, transfers, credit) is a strong plus.
