About us: We believe the next generation of financial services will be powered by stablecoins. Founded in 2021, our mission at BVNK is to accelerate global money movement. We’re building stablecoin-native infrastructure so businesses can move value instantly across borders and networks. With global licenses and T1 bank partnerships, we facilitate billions in transactions for enterprise clients like Worldpay, Deel, LianLian Global, and Rapyd. Our technology is transforming how businesses operate globally by eliminating payment delays, reducing costs, and unlocking trapped capital.  We’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. In 2025, we secured strategic investment from Visa, following our $50 million Series B with Haun Ventures, Coinbase Ventures, Scribble Ventures, DRW Venture Capital, Avenir, and Tiger Global. With the backing of these leading investors, we’re accelerating our growth – and we're looking for smart, ambitious people to help us build the future of financial services. We're incredibly honored to have made Newsweek's list of The Top 100 Global Most Loved Workplaces three years running (most recently in 2025) and to have been recognised by LinkedIn as one of the Top 20 Startups in the UK in 2024. Location: We offer a Hybrid/Remote working policy.  About this role in the team: The Fiat Orchestration subdomain sits within BVNK's Core Banking domain and is responsible for the reliable, scalable processing of fiat currency transactions across multiple banking rails and payment networks. It ensures that every fiat payment; whether an inbound deposit, outbound settlement, or cross-border transfer, is executed accurately, reconciled, and delivered on time. Our product and engineering organisation is split into small autonomous squads empowered to own their problem space. As a Senior Software Engineer in the Fiat Orchestration squad, you'll design and build the backend systems that power the movement of fiat currency through BVNK's platform. You'll work on services that orchestrate payment instructions, interface with banking partners and payment schemes, manage transaction lifecycle states, and ensure settlement integrity at scale. 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. Key Areas of Responsibilities: * Design, develop, and maintain high-performance backend services that power fiat payment processing, including transaction orchestration, settlement, and reconciliation. * Build and evolve integrations with banking partners, payment networks, and financial infrastructure to support multi-rail, multi-currency fiat operations. * Contribute to the architecture and evolution of the fiat processing platform, ensuring reliability, fault tolerance, and data consistency across high-throughput transaction flows. * Build and maintain APIs that manage the full transaction lifecycle — initiation, status tracking, settlement confirmation, and exception handling — consumed by teams across the platform. * Drive improvements to system observability, performance, and resilience, including monitoring, alerting, and incident response. * Collaborate closely with cross-functional partners including product, design, and other engineering squads to deliver high-impact features. * Participate in code reviews, architectural discussions, and technical design sessions to uphold engineering standards. * Contribute to the team's engineering culture by mentoring peers, sharing knowledge, and championing best practices. * Participate in an out-of-hours on-call rotation. What we need from you: * Strong experience as a backend software engineer, with deep proficiency in languages such as Java, Kotlin or similar JVM-based languages. * Experience designing, building, and operating microservices in a distributed systems environment. * Solid understanding of relational databases (e.g., PostgreSQL) and event-driven architectures (e.g., Kafka, SQS/SNS). * Experience with cloud platforms such as AWS, GCP, or Azure. * Experience with containerisation and orchestration technologies including Docker and Kubernetes. * Familiarity with infrastructure-as-code concepts and modern software delivery practices (CI/CD). * Experience with observability and reliability tooling including logging, metrics, tracing, and performance optimisation. * Comfortable working with Jira, Confluence, Git-based workflows, and collaborative engineering practices. * Strong communication skills with the ability to explain technical concepts clearly to both technical and non-technical stakeholders. * A thoughtful, practical approach to problem-solving that considers tradeoffs and avoids over-engineering. Nice to have: * Experience working in fintech, payments, or banking infrastructure, particularly around fiat payment processing, clearing, or settlement. * Exposure to payment schemes, banking APIs, or multi-rail payment routing and orchestration. * Experience with stablecoin or cryptocurrency infrastructure and fiat-to-crypto bridging. * Understanding of domain-driven design and hexagonal architecture patterns. * Familiarity with reconciliation systems, idempotency patterns, and handling eventual consistency in financial workflows. * Experience working in high-growth or fast-scaling technology environments. * Experience contributing to engineering strategy, hiring, or organisational scaling initiatives 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.
