We invite you to join us if you want to be part of a fast-paced environment that will accelerate your career and support you to do some of the best work of your life alongside a passionate and committed team distributed across the Americas. What you'll do We're looking for a Senior Backend Engineer to join Clara's Payments Tribe — We are responsible for powering seamless, secure, and scalable financial transactions across our entire platform. In this role, you will focus heavily on the engine under the hood. Your primary strength and passion lie in backend architecture, distributed systems, system design, and complex data orchestration. While your core focus is the backend, you possess the frontend competence required to build clean, functional user interfaces, and ensure smooth API consumption on our client-side applications. AI fluency is central to how we work on this team — you're expected to use it across the full development lifecycle, from design to deployment, and to reach for it whenever it makes you faster or better. 💡 In this role, you will: • Architect Core Infrastructure: Design, build, and maintain highly secure, resilient backend services in Java/Spring Boot that interface with payment processors and local financial networks across Latin America. • Optimize Data & Performance: Ensure high-availability and asynchronous processing of transaction financial data, keeping system latency low and success rates high. • Bridge to the Frontend: Develop and maintain the React-based frontend applications, dashboards, and internal tooling that interact with your backend services, ensuring deep integration and clean API consumption. • Leverage AI: Use AI tools to automate repetitive engineering workflows, accelerate delivery, and close skill gaps — from scaffolding new banking integrations to generating and reviewing code. • Lead & Mentor: Set the technical bar through backend code reviews, robust system design reviews, and hands-on mentorship of junior and mid-level engineers. • Own System Observability: Implement monitoring, logging, and tracing across the full stack to quickly isolate and fail-gracefully when external financial APIs experience downtime. 👤 Who you are We're looking for an autonomous, systems-minded engineer who loves complex data flows, values strict security, and understands how to deliver clean code from database to browser. Must haves: • Experience: 5+ years of software engineering experience, with a heavy specialization in Backend/Systems development within a Fullstack or Distributed Sys
