Full-Stack Software Engineer: React, TypeScript, Python, AWS

**Before you apply** * Your CV must be submitted in English. * Strong English communication skills are required, both written and spoken. * Candidates must be physically located in Brazil. Proof of residency may be requested during the hiring process. **About** We are looking for a full\-stack engineer who enjoys working on real products, not just isolated tickets. Our web application presents interesting engineering challenges: complex workflows, large volumes of data, and real\-time user interaction. The core platform is already in place \- a React/TypeScript frontend, a Python backend, and a set of third\-party integrations that perform heavy processing and content generation. Your role is simple in principle: make the product better. You will ship features, fix problems, improve reliability, and take ownership of the functionality you build across the stack \- from the UI a user interacts with, to the Python service handling the request, to the external provider that ultimately delivers the result. This is a hands\-on product engineering role for someone who values clean code, steady progress, and maintaining a healthy codebase over time. **What You Will Do** You will work across the full stack to improve and evolve the product. That includes: * Building and shipping new product features across React/TypeScript frontend and Python backend services. * Owning backend service logic in Python, including business workflows, data processing, and external provider integrations. * Diagnosing and resolving issues that span multiple layers of the system \- frontend state, APIs, backend services, and third\-party providers. * Developing responsive and high\-performance React interfaces, with well\-structured components and reliable state management. * Making targeted changes to our Terraform infrastructure when new features require cloud resources, roles, or permissions. * Collaborating with product managers, designers, and engineers to break down requirements into clear, deliverable work. * Writing clean, maintainable, well\-tested code and participating in code reviews. * Identifying and addressing technical debt where necessary to keep the codebase stable as the product evolves. **What We Are Looking For** * Solid experience as a full\-stack engineer building and shipping production web applications. * Strong experience with React and TypeScript, including component architecture, complex state management, and frontend performance. * Proven experience writing backend services in Python, including business logic, API design, and reliable error handling. * Experience integrating third\-party APIs and external services, including authentication, rate limits, retries, and failure handling. * Working knowledge of Terraform and infrastructure\-as\-code sufficient to modify existing configurations. * Strong debugging skills across the stack \- comfortable tracing issues from browser behaviour through APIs, backend services, and cloud logs. * Experience using AI\-assisted development tools to improve productivity. * Strong communication skills and comfort working in an existing production codebase rather than a greenfield environment. **Bonus Experience** Experience in any of the following areas is useful but not required: * AWS cloud services, particularly around compute, storage, and managed services. * CI/CD pipelines and GitLab workflows. * Production observability tooling (logging, monitoring, tracing). * Working in Agile development environments. **Why This Role Is Interesting** You will work on a real product used by real users, where improvements you ship quickly make a difference. The platform is already established, which means the focus is not building from scratch, but improving, scaling, and evolving a system that is already in production. If you enjoy owning features end\-to\-end and steadily improving a product over time, this role will suit you well.
