The Role
Own end-to-end partner and customer integrations: qualify requests, design and build connectors, implement data mappings and webhooks, ensure idempotency and observability, coordinate with partner teams, and deliver runbooks and handoffs. Feed integration patterns back into the platform to increase reuse and reliability.
Summary Generated by Built In

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

Clara is committed to hybrid work, combining the flexibility of remote work with the collaboration, connection, and professional development benefits of working together in the office. The team doesn't have fixed in-office days, but we encourage our Claridians to come into the office based on business or team needs.


Where we work

This is a remote-first role: you'll work from home day to day. You'll ramp up in person with the team, and come together in person for team moments, events and customer visits through the year.

Why Clara
  • A high talent-density team driven to make an impact in Latin America — low ego, high ownership.
  • Competitive salary and stock options (ESOP) from day one.
  • An annual learning budget and accelerated development paths.
  • English is our working language, with Spanish and Portuguese every day.
How we work
  • Clarity — Open and direct communication: we say what we mean and give context where it matters.
  • Simplicity — If it can be simpler, it should be.
  • Ownership — We own everything we do, end to end. When something needs to happen, we don't wait.
  • Pride — We hold ourselves to a high standard, and it shows in what we deliver.
  • ABC (Always Be Changing) — We adapt fast, embrace change, and keep learning.
  • Inclusivity — Diverse ideas, stories and perspectives build a better Clara.

If you meet the must-haves, apply — the nice-to-haves are a bonus, not a requirement.

Skills Required

  • 4+ years of backend software development experience with hands-on API integrations, webhooks, and data mapping
  • Experience working directly with external partners or customers in a technical capacity and owning the relationship
  • Design solutions from scratch to meet customer needs and scope integration work quickly
  • Deep fluency in integration patterns: REST, event-driven architectures, idempotency, OAuth/token management
  • Strong proficiency in one or more backend languages
  • Proficiency in Java
  • Working knowledge of observability fundamentals: logs, metrics, tracing, alerting, and SLOs
  • Exposure to integration platforms or connector frameworks (e.g., N8N, Zapier, or custom-built equivalents)
  • Working proficiency in English and Spanish, or English and Portuguese
  • Excellent communication skills with technical and non-technical audiences
  • Ability to move fast in ambiguous environments and qualify/scope integrations rapidly
  • Experience using AI tools to accelerate development and repetitive mapping tasks
  • Familiarity with fintech/payments, PCI/PII handling, AWS, or Kafka/event streaming platforms
