Senior Fullstack Engineer (Ingeniero/a de Software Fullstack Senior) - Hybrid

Your responsibilities will include: Designing and building backend services that power the onboarding engine: sign-up, KYB/KYC flows, document collection, verification orchestration, and account activation. Contributing to the frontend: building intuitive, responsive interfaces that reduce friction at a high-stakes moment for the customer — and that make a complex compliance process feel simple. Owning integrations with external providers — identity verification, document validation, business data sources — abstracting their complexity behind clean, resilient internal APIs. Collaborating cross-functionally with Product, Design, Risk, and Compliance to translate regulatory requirements and activation goals into great product experiences. Applying AI tools to ship faster and improve how the team works Elevating the team through code reviews, pairing, and sharing what you know with peers Who you are 5+ years of software engineering experience with solid execution in production environments. Strong foundation in Java and the Spring ecosystem — Spring, Spring Boot, Spring Batch — for building robust backend services, with genuine appetite to go deeper on the frontend (React) too. A strong React engineer hungry to own the backend is equally welcome. Comfortable architecting scalable, distributed systems and microservices that hold up under the demands of core financial products. Solid data modeling instincts, with hands-on experience running PostgreSQL and Redis for both transactional and caching needs. Experience building and securing RESTful APIs and integrations with third-party providers — comfortable with async and event-driven patterns (Kafka), error handling, and the messiness of external dependencies. Familiarity with cloud platforms, preferably AWS, and modern dev tooling. A track record of mentoring engineers and raising the bar on best practices and quality — through code reviews, pairing, and sharing what you know. English proficiency, with the ability to lead technical discussions across geographies and turn business goals into technical solutions that actually land. High autonomy and ownership, plus an AI-native approach: you use AI tools actively in your daily work — coding, debugging, automation — and keep pushing further. We've kept this list short on purpose — these are the things that actually matter. If you check most of these and the rest you'd close with curiosity and the right tools, we want to hear from you.

Clara’s Hybrid Policy Claridians in a hybrid mode split their time between working from the office, talking to or visiting customers, or working from home. This hits a balance between bringing people together for in-person collaboration and learning from each other, while supporting flexibility about how to do this in a way that makes sense for each individual and team. We don't enforce a minimum number of days for most roles, but you're expected to spend time at the office organically, and be at the office most days during your ramp-up or when required by your leader.
