Processing billions annually, we empower enterprises worldwide to send, receive, convert, and settle stablecoins and fiat seamlessly through a single integration.

Our mission is to accelerate global money movement, and we're assembling a world-class team to make it happen.

We're incredibly honored to have been recognized by:

About the team

Treasury Automation builds the control layer for how money moves at BVNK. Every day, client and company funds flow across banks, blockchains and liquidity providers, in fiat and digital assets, through regulated entities in several jurisdictions. Our platform keeps that money in the right place, in the right structure and on the right rail, so it’s available when it’s needed, settled when it’s owed, and protected when it belongs to clients.

The platform turns treasury policy into automation. It decides when funds need to move, moves them, and proves that every movement is correct.

What you'll do

• Build liquidity management: track positions across every account, venue and chain, and rebalance funds automatically
• Power accurate, on-time settlement with liquidity providers and partners
• Automate safeguarding and segregation of client funds across entities and jurisdictions
• Evolve the treasury rules engine that turns policy into fund movements, for BVNK and Layer1 customers
• Design event-driven services and long-running Temporal workflows: idempotent, traceable until confirmed and auditable to the standard regulators expect
• Own production: observability, alerting, runbooks and on-call for systems that move real money
• Act as a technical leader: shape designs, raise the bar in code review, mentor engineers and help the Tech Lead set direction

What you'll bring

• Strong backend experience in Java/Kotlin building distributed systems in production
• Hands-on experience with event-driven architecture (Kafka or similar) and workflow orchestration (Temporal or similar)
• A track record of building financially critical systems where correctness, idempotency and reconciliation matter
• Understanding of money movement: payments, settlement, liquidity or treasury, across fiat and/or crypto
• Comfort with cloud-native tooling (Kubernetes, ArgoCD, Grafana) and SQL/data warehouses
• Experience leading designs across teams and turning unclear business needs from treasury users into clean systems
• Bonus: FinTech and payments: Experience in payments, banking or other regulated financial services.

What we need from you

• 5+ years of backend engineering experience in Java/Kotlin with Spring Boot.
• Strong distributed systems fundamentals — experience building microservices with event-driven architectures (Kafka, SQS), relational databases (MySQL/PostgreSQL), and caching (Redis).
• Experience with account or wallet systems — you've built or maintained systems that manage account/wallet lifecycle, state machines, or financial entity management where correctness and auditability are non-negotiable.
• Solid grasp of domain-driven design and hexagonal architecture — you can model complex domains cleanly, define bounded contexts, and build services with well-defined boundaries and interaction modes.
• API design skills — experience designing and evolving RESTful APIs that serve both internal services and external customers, with attention to backwards compatibility and developer experience.
• Collaborative and proactive communication — you work effectively with product managers, operations teams, and cross-domain engineers. You're comfortable operating across time zones in a remote-first setup.
• Production ownership mentality — experience with on-call, incident response, and operational monitoring (Grafana, Prometheus, Micrometer). You take pride in the reliability of systems you build.
• Familiarity with CI/CD pipelines, infrastructure-as-code, and observability tooling.
• Open to participate in out of hours on call rota

Nice to have

• Experience with multi-tenant architectures and tenant migration patterns.
• Background in embedded finance, BaaS, or payment platforms serving B2B2C models.
• Familiarity with database migrations in high-throughput systems.
• Experience with dynamic validation engines or capabilities/feature-flag systems.
• Experience with stablecoin, crypto, or blockchain-adjacent products.

What you can expect from us

• Fair and competitive salary at every stage of your growth
• Flexible working hours, with hybrid working at its heart
• A culture built on passionate, growth-minded people
• A flexible approach to holiday
• Opportunities to travel to our offices around the world
• An open and creative environment where you can help us define the future of BVNK, its culture, and its opportunity sets

At BVNK, we are focused on building a diverse and inclusive team. While you may not meet all of our requirements, we’d encourage you to apply if you meet the majority of our expectations. You may be a great fit for this role or another role in our team.
