Working At Bitso

We are a diverse team that takes pride in understanding the perspectives of others. We fully embrace working remotely and we are eager to act, improve and accelerate progress inside and outside of our organization.

To drive revolutionary changes in society and make crypto useful, we delight our customers with world-class products, deep care, and intentional empathy.

Your Purpose 

At Bitso, the Software Engineer on the Nexus Squad owns the reliability, scalability, and evolution of our mission-critical pay-in and pay-out systems — the financial backbone that moves billions of dollars worldwide. You will design and deliver event-driven, high-throughput solutions that ensure every pay-in and pay-out is fast, accurate, and resilient.

Working closely with product, infrastructure, and compliance stakeholders, you will shape the technical direction of a domain where the bar for quality is exceptionally high, resilience is built through continuous learning, and every millisecond of performance matters — for the millions of retail users and the businesses that rely on Bitso to power their financial operations.

Reports To

This role reports to the Nexus Engineering Manager.

Who You Are 

• You are experienced in Java backend development, with a proven track record of shipping production systems at scale.
• You are familiar with event-driven architecture patterns (event sourcing, CQRS, sagas) and have hands-on experience operating Apache Kafka in high-throughput, real-money environments.
• You have designed and implemented distributed, fault-tolerant microservices that handle financial or similarly critical transactional data.
• You have solid experience with relational databases (PostgreSQL preferred), including schema design, migrations, and query optimization.
• You are comfortable with cloud-native infrastructure (AWS, GCP, or equivalent), containerization (Docker, Kubernetes), and CI/CD pipelines.
• You communicate complex technical concepts clearly in English, written and spoken, to engineering peers, product managers, and senior leadership.
• You work with a high degree of autonomy and ownership — you identify problems, propose solutions, and see them through to production.
• You are familiar with AI-assisted development flow and tools (Cursor, Claude, CodeRabbit).
• You have a strong sense of urgency and are comfortable operating in a fast-paced, high-stakes fintech environment.
• Financial Domain (nice to have):Familiarity with payment rails, reconciliation or idempotent transaction processing in financial systems is a strong plus.

What You Will Do

• Own pay-in and pay-out systems: design, build, and maintain the core infrastructure that processes financial transactions and moves billions of dollars worldwide.
• Architect event-driven solutions: design Kafka-based pipelines and workflows that guarantee correctness, ordering, and resilience at scale.
• Drive technical decisions: lead architecture discussions, define and use patterns, and set standards for the pay-in and pay-out domain in collaboration with the Nexus team.
• Deliver high-quality code: write clean, well-tested, high-performance Java code and champion engineering best practices through code reviews.
• Embrace AI-assisted development: leverage tools like Cursor, Claude, and CodeRabbit as part of your everyday workflow, contribute to skills and guardrails development, and apply Spec-Driven Development (SDD) practices to ensure solutions are well-defined, reviewable, and aligned before implementation begins.
• Ensure system reliability: proactively monitor, debug, and resolve production incidents with a focus on root-cause analysis and lasting fixes.
• Collaborate cross-functionally: partner with Product, Compliance, and Finance stakeholders to translate complex business requirements into sound technical solutions.
• Mentor and uplift: share knowledge with fellow engineers, contribute to internal tech talks, and foster a culture of continuous improvement within the squad.
• Improve observability: instrument services with comprehensive metrics, logs, and traces to enable rapid diagnosis and confident deployments.
