APAC· Remote · Full Time · Individual Contributor · 3+ Years of Experience 1. Overview Who We Are Yuno is the payment orchestrator built for global scale, founded by the team behind Rappi, one of Latin America's most ambitious tech companies. We connect businesses to 300+ payment methods worldwide through a single integration. We're growing fast, and we're looking for engineers who want to build the infrastructure moving money globally. The Role We’re looking for a Backend Engineer to join our Integrations Team, the group responsible for connecting Yuno’s platform to PSPs, acquirers, payment gateways, fraud and 3DS providers worldwide.You'll build and maintain the integrations that are core to our product, working across countries, providers, and complex payment rails in a fast-moving, global environment. 2. How Yuno Will Challenge You AI-First Engineering At Yuno, AI is not optional, it’s foundational to how we build. You will: Actively use AI-assisted tools (e.g., Copilot, Claude, or similar) for coding, testing, debugging, and documentation. Integrate AI into your daily workflow to improve speed, quality, and decision-making. Continuously explore ways to automate development, testing, and operational processes using AI. Building at Scale Build and evolve high-performance APIs and microservices in Go, designed for reliability, low latency, and scale. Take end-to-end ownership of features and integrations — from discovery and design to production rollout and monitoring. Develop and extend integration frameworks that support payment processing, fraud detection, and authentication flows (e.g., 3DS) across multiple regions. Technical Excellence Write clean, well-tested, production-ready code with a strong focus on quality, observability, and documentation. Apply secure software development practices, including OWASP standards, data privacy, and compliance requirements. Embrace an AI-first engineering approach — leverage AI-assisted development, code generation, and automated testing as part of your daily workflow, not as an afterthought. Cross-functional Execution Work closely with Product, Compliance, and Business teams to translate real payment problems into elegant technical solutions. Deliver in an agile environment against a fast-moving roadmap, adapting to shifting priorities across markets and providers. 3. What You Bring The Essentials Solid backend engineering experience building high-throughput, production-grade systems in Golang Strong understanding of microservices and event-driven architectures, APIs, and integration patterns. Experience with SQL and relational databases (PostgreSQL preferred). Knowledge of secure software development practices and OWASP principles. Demonstrated experience with unit testing and Git-based workflows. Comfort working with AI-assisted development tools (Claude Code, Copilot, or similar) as part of your engineering workflow. Adaptability to a constantly evolving roadmap and competing priorities. Ability to communicate technical problems clearly to both technical and business audiences. Full professional proficiency in English — written and spoken. What Would Make You Stand Out Experience in the payments industry or integrating with Payment Service Providers. Hands-on experience with cloud and DevOps environments (AWS, Docker, Kubernetes). 4.
