The posting

We are seeking a Senior Full-Stack Software Developer to join the Product Development Team of our client and help build, improve, and maintain AI-enabled product capabilities. This is a backend-focused role that also requires strong hands-on experience with React and modern web technologies.

You will work closely with the Development Manager, Product Owner, Interaction Design team, and other stakeholders to translate product requirements and user workflows into high-quality, reliable software.

A major focus of the role is improving code quality, writing maintainable and well-documented code, testing your own work, and using AI development tools such as Claude Code to support implementation and code reviews.

Key Responsibilities

  • Design, develop, test, and refine software implementations for a product environment.

  • Develop AI-enabled capabilities, including LLM-powered features, intelligent workflows, automation, recommendations, and integrations with AI platforms/APIs.
  • Write clean, maintainable, well-documented, and unit-testable code.
  • Develop and maintain unit tests using Test-Driven Development and other appropriate testing practices.
  • Use Claude Code as part of the development workflow, including mandatory Claude-assisted code reviews.
  • Participate in formal code reviews and make improvements based on feedback.
  • Create software implementation designs and technical documentation.
  • Develop architecture documentation, database schema diagrams, entity relationship diagrams, and sequence diagrams.
  • Work with SQL databases, including database design and data-related implementation.
  • Participate in planning sessions and provide estimates for development efforts.
  • Demonstrate completed implementations to stakeholders and incorporate feedback.
  • Develop software installation packages for customer workstations and servers when required.
  • Identify opportunities to improve code quality, development practices, performance, and maintainability.
  • Contribute to technical problem-solving and the design of practical, scalable solutions.
  • Must be based in Latam.

Requirements

  • 8+ years of professional software development experience.
  • Strong experience developing software products in a product development environment.
  • Strong backend development experience with .NET / C#.
  • Strong hands-on experience with React.
  • Strong knowledge of JavaScript, HTML5, and CSS3.
  • Experience developing and consuming RESTful APIs.
  • Strong SQL and database development experience.
  • Experience with JSON and XML data structures.
  • Experience with distributed architectures and asynchronous request handling.
  • Strong understanding of software design patterns and modern software architecture.
  • Experience with patterns such as MVC and MVVM.
  • Experience writing and maintaining unit tests for your own code.
  • Strong understanding of software quality, maintainability, and development best practices.
  • Experience with Git or SVN.
  • Experience with browser-based and responsive web applications.
  • Practical experience with AI technologies, including Large Language Models (LLMs), Agentic AI, and/or Machine Learning.
  • Experience using Claude Code, including AI-assisted development and code review workflows.
  • Strong technical documentation and written communication skills.
  • Analytical and pragmatic approach to problem-solving.

Nice to have

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
