We're now part of Mastercard, and together we're building a network for every form of money - one that delivers more reach, more capability and more choice.\nWe enable businesses to build financial products, unlock new markets, and move money in seconds across 130+ countries, with 40+ licenses for fiat and digital assets globally. Processing billions annually, we empower enterprises worldwide to send, receive, convert, and settle stablecoins and fiat seamlessly through a single integration.\nOur mission is to accelerate global money movement, and we're assembling a world-class team to make it happen.\nTrusted by industry leaders like Corpay, Worldpay, Deel, and Flywire, we deliver the infrastructure that makes new forms of money usable within the financial systems customers already rely on today.\nBy combining Mastercard's global payment reach and trusted networks with BVNK's stablecoin infrastructure, we're building the trusted operating layer for the evolution of money movement, helping customers participate in emerging digital networks without having to rebuild their businesses around every new innovation.\nWe're a diverse team spread across EMEA, North America, and APAC, with a shared belief that stablecoins are the new infrastructure layer for financial services, and that BVNK is at the forefront of this shift.\nWe're incredibly honored to have been recognized by:\nCNBC World's Top Fintech Companies (2026)\nFXC Intelligence Top 100 Cross-border Payment Companies (2026)\nNewsweek's The Top 100 Global Most Loved Workplaces (three years running, most recently 2025)\nLinkedIn as one of the Top 20 Startups in the UK (2025)\nLocation: We offer a Hybrid/Remote working policy.\nFunction: Engineering\nWe're looking for a talented Software Engineer to join the Wallets subdomain within BVNK's Ledger domain.\nThe Wallets subdomain is responsible for the complete lifecycle of customer wallets: creation, activation, blocking, suspension, and termination; across fiat and crypto, for direct merchants, embedded partners, and their underlying customers. \nThis is high-impact, foundational work. As BVNK scales into new products and new entity structures, the Wallets subdomain is at the centre of it all: every new product capability, every new customer type, and every new custody model needs a wallet representation that is accurate, compliant, and scalable. You'll be building the infrastructure that makes all of this possible.\nOur product and engineering organisation is split into small autonomous squads empowered to own their problem space. You’ll be expected to form strong opinions and execute in a fast but sustainable way, advocating for the simplest solution that achieves the outcomes our customers are looking for.\nKey Areas of Responsibilities:\nOwn and evolve the Wallet - Design and implement services that manage the full wallet lifecycle: creation, activation, blocking/unblocking, suspension, and termination across fiat and crypto wallets for all customer types.\nIntegrate across domains - Collaborate internally with a wide range of domains - Digital Assets, Fiat, Onboarding, Billing etc.\nDesign for reliability and horizontal scale - Build services following BVNK's hexagonal architecture patterns. Contribute to HPA tuning, DLQ handling, and performance optimisation for production workloads.\nOwn operational excellence - Participate in on-call rotations, incident response, and production monitoring for wallet-critical services. \nShip with quality - Write well-tested, well-documented code. Contribute to architecture reviews and technical design submissions. Uphold BVNK's microservices standards.\nWhat we need from you:\n5+ years of backend engineering experience in Java/Kotlin with Spring Boot.\nStrong distributed systems fundamentals - experience building microservices with event-driven architectures (Kafka, SQS), relational databases (MySQL/PostgreSQL), and caching (Redis).\nExperience 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.\nSolid 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.\nAPI design skills - experience designing and evolving RESTful APIs that serve both internal services and external customers, with attention to backwards compatibility and developer experience.\nCollaborative 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.\nProduction ownership mentality - experience with on-call, incident response, and operational monitoring (Grafana, Prometheus, Micrometer). You take pride in the reliability of systems you build.\nFamiliarity with CI/CD pipelines, infrastructure-as-code, and observability tooling.\nOpen to participate in out of hours on call rota\nNice to have:\nExperience with multi-tenant architectures and tenant migration patterns.\nBackground in embedded finance, BaaS, or payment platforms serving B2B2C models.\nFamiliarity with database migrations in high-throughput systems.\nExperience with dynamic validation engines or capabilities/feature-flag systems.\nExperience with stablecoin, crypto, or blockchain-adjacent products.\nWhat you can expect from us:\nFair and competitive salary at every stage of your growth\nFlexible working hours, with hybrid working at its heart\nA culture built on passionate, growth-minded people\nA flexible approach to holiday\nOpportunities to travel to our offices around the world\nAn open and creative environment where you can help us define the future of BVNK, its culture, and its opportunity sets\nAt BVNK, we are focused on building a diverse and inclusive team.
