What if your next role helped build the financial backbone of Latin America’s most ambitious companies?

Clara is the leading B2B spend management platform in the region, used by 20,000+ companies to gain clarity, control, and speed in how they manage payments, credit, and expenses. Our all-in-one solution combines locally issued corporate cards, bill pay, financing, and a powerful SaaS platform built to scale with our customers.

Backed by world-class investors like General Catalyst, Goldman Sachs, Kaszek, and Citi Ventures, we’re building the financial infrastructure that powers how Latin America works — and works better.

About the Role

Be responsible for developing and delivering backend services that power our mobile applications. As a core member of the mobile team, you’ll collaborate closely with iOS and Android engineers to ensure our APIs are mobile-first—designed for responsiveness, efficiency, and resilience in real-world network conditions. Your work will directly impact the performance and reliability of the mobile experience for our users.

Key Responsibilities

• Build and secure RESTful APIs with TLS encryption and modern auth protocols (OAuth2, JWT, etc.)
• Write efficient, clean, maintainable, and well-tested code with clear documentation.
• Participate in code reviews and contribute to the development of technical standards.

What We're Looking For

• 7+ years of experience in Java (Spring/Spring Boot/Spring Batch) development.
• Strong experience designing and implementing API services, including optimization for mobile clients—focused on expected response times, resilience to unstable or low-bandwidth connections, and efficient data handling to minimize consumption.
• Experience with swagger/OpenAPI to facilitate integration with mobile teams.
• Experience with relational databases (PostgreSQL), NoSQL databases (Redis), and data modeling.
• Experience with cloud platforms (AWS).
• Hands-on experience with secure API development using TLS, OAuth2, and enterprise-grade encryption methods
• Firm grasp of backend design principles, modularity, and maintainability
• Passion for solving complex problems and building systems that scale
• Experience with system design and the ability to architect scalable, high-availability solutions.
• Excellent analytical and problem-solving capabilities.

Nice to Have

• Previous experience in fintech or financial services
• Familiarity with AWS components (e.g., ECS, API Gateway, SQS, RDS, CloudWatch)
• Exposure to containerization and orchestration (Docker, Kubernetes)
• Understanding of enterprise data pipelines, messaging systems (Kafka, RabbitMQ)
• CI/CD tooling and DevOps best practices

Why Join Us

• Be a key player in shaping our core backend systems.
• Collaborate in a high-performance, remote-friendly environment.
• Room to innovate, learn, and lead technical initiatives from the ground up.

If you're ready to build backend systems that power real impact, we’d love to hear from you. Apply now.
