Full Stack Software Engineer - Java - React

Clara
Cambridge, MA
Job Description
Role Overview

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.

What You Will Do

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.

Why It Might Be a Fit

Must have 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).

Requirements

  • 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
  • Working proficiency in English and Spanish

Benefits

  • Competitive salary
  • Stock options (ESOP) from day one
  • Multicultural team with daily exposure to Portuguese, Spanish, and English (our corporate language)
  • Annual learning budget
  • Internal accelerated development paths
  • Flexible vacation
  • Hybrid work model focused on results
