BVNK - Tech Lead (Backend): Billing & Fees

• Own the technical direction of Billing & Fees: Define and drive the architecture, technical strategy and engineering roadmap for billing services, ensuring solutions support BVNK's evolving commercial models, transaction volumes and operational requirements. • Own the technical direction of Billing & Fees: • Lead the development of scalable billing infrastructure: Architect and build services responsible for fee policy configuration, fee calculation, invoice generation, billing adjustments and reconciliation, replacing manual processes with automated, reliable workflows. • Lead the development of scalable billing infrastructure: • Drive end-to-end billing automation: Design robust data pipelines and integrations connecting systems such as Snowflake, Salesforce, Ledger and internal financial services, ensuring accurate data flows from transaction processing through to invoicing and reporting. • Drive end-to-end billing automation: • Ensure financial accuracy and auditability: Establish engineering patterns that support financial correctness, including idempotency, traceability, reconciliation, exception handling and comprehensive audit trails. Ensure billing discrepancies can be identified, investigated and resolved effectively. • Ensure financial accuracy and auditability: • Lead architectural design and technical decisions: Drive technical design submissions, architecture reviews and service design, applying domain-driven design, hexagonal architecture and event-driven patterns to build well-defined, maintainable services. • Lead architectural design and technical decisions: • Provide hands-on technical leadership: Remain actively involved in designing, building and reviewing production code. Mentor engineers, provide technical guidance, unblock complex challenges and raise engineering standards across the squad. • Provide hands-on technical leadership: • Collaborate across engineering and business domains: Partner with Product, Finance, Commercial, Back Office, Ledger, Digital Assets and Fiat teams to translate complex requirements into clear technical solutions and ensure reliable integration across systems. • Collaborate across engineering and business domains: • Own reliability and operational excellence: Establish strong standards for observability, monitoring, performance and incident response. Guide the team in managing production workloads, including message processing failures, dead-letter queues, service recovery and operational resilience. • Own reliability and operational excellence: • Drive engineering quality and delivery: Set expectations for testing, CI/CD, documentation and technical debt management. Work with the team to deliver high-quality solutions consistently while balancing speed, maintainability and long-term platform health. • Drive engineering quality and delivery: • What we need from you: • 7+ years of backend software engineering experience, with strong hands-on expertise in Java/Kotlin and Spring Boot, including experience leading technical initiatives or providing technical leadership to other engineers. • 7+ years of backend software engineering experience • Proven experience designing and delivering complex, distributed, production-grade systems, with a strong understanding of microservices, event-driven architectures (Kafka, SQS), relational databases (MySQL/PostgreSQL) and caching technologies such as Redis. • complex, distributed, production-grade systems • Experience working on financially sensitive systems, such as billing, invoicing, payments, ledger, fee calculation or reconciliation platforms, where accuracy, consistency, auditability and reliability are critical. • financially sensitive systems • Strong architectural expertise, including domain-driven design, hexagonal architecture, service decomposition, bounded contexts and asynchronous communication patterns. • Demonstrated ability to own technical architecture and drive engineering decisions, balancing scalability, reliability, delivery timelines and business requirements. • own technical architecture and drive engineering decisions • Strong API design experience, including building and evolving RESTful APIs, managing backwards compatibility, and creating reliable integration patterns across internal and external systems. • Solid understanding of financial data integrity, including transactional consistency, idempotency, error recovery and reconciliation in distributed environments. • Experience mentoring and guiding engineers through technical design, code reviews, problem-solving and complex delivery challenges. • A strong production ownership mindset, with experience operating business-critical systems, participating in on-call rotations, managing incidents and using observability tooling such as Grafana, Prometheus and Micrometer. • Familiarity with CI/CD pipelines, infrastructure-as-code, automated testing and modern software delivery practices. • Strong communication and stakeholder management skills, with the ability to work effectively across Engineering, Product, Finance and Commercial teams in a distributed, remote-first environment. • Comfortable being both a hands-on engineer and a technical leader, taking ownership of challenging problems while enabling others to deliver successfully. • both a hands-on engineer and a technical leader • 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.
