Fullstack Software Engineer - [Ingeniero de Software Fullstack]

About the role

Clara is the leading platform in Latin America for companies to execute and manage every payment operation. More than 50,000 leading and fast-growing businesses run on our corporate cards, bill pay, financing and B2B payments, and in 2025 the Financial Times named Clara the region’s fastest-growing company. We’re passionate about helping every company we work with become more effective—and, through that, raising the region’s competitiveness. We’re ~400 people, backed by Notable Capital, Coatue, Kaszek, monashees, DST Global, ICONIQ, General Catalyst and Goldman Sachs, among others.

What you’ll do

We’re looking for a Full Stack Software Engineer to own backend and frontend development in Clara’s Collections squad. You’ll build features end-to-end — from data models and APIs to the interfaces our customers and internal teams use. This is a high-ownership role: you won’t wait for a ticket to tell you what to do; you’ll identify gaps, propose solutions, and ship.

- Design and implement backend services in Java + Spring Boot, with a focus on financial flows (payments, collections, reconciliation)

- Build and maintain frontend interfaces in React + TypeScript — you’re comfortable owning a feature across both layers

- Model data and manage PostgreSQL and Redis for transactional and caching needs

- Work with event-driven architectures (Kafka or similar) in a distributed microservices environment

- Build and secure RESTful APIs for internal and external consumption

- Use AI coding tools (Claude Code, Copilot, Cursor) as a default part of your workflow — we expect this, not just welcome it

- Collaborate with your Pod Lead and PM to translate product needs into technical decisions, and push back when something doesn’t make sense

Who you are

We’re looking for someone who meets the minimum requirements to be considered for the role. The preferred qualifications are a bonus, not a requirement.

Must haves

- 3–5 years of backend development experience in Java, including Spring Boot

- Hands-on experience with React and TypeScript — you’ve shipped real UI, not just tutorials

- Solid understanding of PostgreSQL and distributed systems fundamentals

- Experience with CI/CD, Docker, Git, and cloud platforms (AWS preferred)

- AI-augmented development is how you work — you use AI tools daily to write, review, and debug code; you can speak concretely about how it’s changed your output

- You identify what’s missing before someone asks — proactive, not reactive

- Working proficiency in English and Spanish

Nice to haves

- Experience with Kafka, RabbitMQ, or other message brokers

- Background in financial services, payments, or fintech — domain ramp is real; prior exposure matters

- Experience in Kubernetes and production observability

- You’ve built something — side project, open source, internal tool — that you’re proud of and can walk us through
