Software Engineer - Latam or Europe

About the role

This Software Engineer role at Bitso focuses on the core infrastructure for financial transactions, specifically pay-in and pay-out systems. The work involves designing, building, and maintaining these systems, which process billions of dollars globally. A key aspect is architecting event-driven solutions using Kafka to ensure data correctness, ordering, and resilience at scale.

The position requires driving technical decisions, setting standards for the pay-in and pay-out domain, and delivering high-quality, well-tested Java code. Engineers are expected to leverage AI-assisted development tools and apply Spec-Driven Development practices. Success in this role means ensuring system reliability through proactive monitoring and debugging, while also collaborating with product, compliance, and finance teams to translate business needs into technical solutions.

Beyond technical contributions, this role includes mentoring fellow engineers, contributing to internal knowledge sharing, and fostering continuous improvement within the team. Improving observability by instrumenting services with comprehensive metrics, logs, and traces is also a key responsibility, enabling rapid diagnosis and confident deployments.

The compensation for this role ranges from $90,000 to $150,000 USD annually.
