Yuno - Staff Engineer

• 8+ years of backend engineering experience building high-throughput, production-grade systems in Go, Java, or Kotlin — with at least 3 years operating at Senior/Staff/Lead level. • Demonstrated track record of leading architectural decisions adopted by multiple teams — not just within your own squad. • Direct experience in payments, fintech, or PCI-regulated systems — integrations with PSPs, acquirers, fraud/3DS providers, or comparable regulated infrastructure. • Deep expertise in microservices, event-driven architectures, APIs, and integration patterns at scale. • Strong experience with SQL and relational databases (PostgreSQL preferred); comfort with caching, queues, and async pipelines. • Experience defining technical standards, frameworks, or platform abstractions that other teams build on. • Working knowledge of secure software development, OWASP, and PCI-DSS principles. • Comfort using AI-assisted development tools (Claude Code, Copilot, or similar) as a core part of your workflow — and an opinion on where they help vs. hurt. • Ability to communicate complex technical topics clearly to engineers, Product, and executive audiences alike. • Demonstrated experience mentoring and growing other engineers. • Full professional proficiency in English — written and spoken. • What Would Make You Stand Out • Prior Staff or Principal Engineer title at a payments orchestrator, PSP, gateway, or fintech infrastructure company. • Contributions to integration frameworks, payment orchestration platforms, or open-source projects in the payments / fintech space. • Experience scaling integrations across multiple regions (LATAM, APAC, EMEA, NA) and the regulatory regimes that come with them. • Public technical writing, conference talks, or other evidence of external technical voice. • Hands-on experience with cloud and DevOps environments (AWS, Docker, Kubernetes). • 4.
