  • Design and maintain the execution architecture of applications, in collaboration with the software development team based in the United States.
  • Transform algorithms, prototypes, and research code into applications ready for production environments.
  • Clean, refactor, and optimize existing Python code, improving its readability, performance, security, scalability, and maintainability without altering its functionality.
  • Design modular and decoupled solutions by applying SOLID principles, Clean Architecture, dependency injection, and other design patterns.
  • Define and apply testing strategies that include unit, integration, and end-to-end tests, using mocking techniques when necessary.
  • Perform code reviews and ensure compliance with software engineering standards and best practices.
  • Act as a technical reference for research teams, guiding them in architecture, code quality, testing, and the development of production-ready solutions.
  • Define development principles, standards, and procedures that facilitate the evolution and maintenance of applications.
  • Work with both batch and streaming data architectures and processes.
  • Collaborate with data scientists and platform specialists to align solutions with the corporate architecture and security requirements.
  • Participate in the integration and deployment of applications within cloud environments and data platforms.

What we're looking for

  • Bachelor's or Master's degree in Computer Engineering, Software Engineering, or similar technical education.
  • At least 5 years of professional experience in software development.
  • Advanced experience developing and maintaining Python applications in production, beyond scripts, notebooks, or data analysis tasks.
  • Experience designing modular, decoupled, scalable, and maintainable software architectures.
  • A strong command of English, both written and spoken, is essential.
  • Knowledge and practical application of SOLID principles, Clean Architecture, dependency injection, and design patterns.
  • Experience refactoring complex code and algorithms, ensuring existing functionality is preserved correctly.
  • Experience with unit testing, integration testing, end-to-end testing, and mocking.
  • Experience performing code reviews and promoting code quality and development best practices.
  • Experience working with Git, branching strategies such as Gitflow, and CI/CD processes.
  • Knowledge of distributed systems and modern data architectures.
  • Familiarity with batch and streaming processes and patterns such as the Medallion architecture, Lambda, or other equivalent architectures.
  • Ability to take on technical leadership responsibilities, define standards, and act as a reference for other team members.
  • Strong communication, problem-solving, and collaboration skills within multidisciplinary teams.

Nice to have

  • Experience deploying applications on Azure Cloud and Databricks.
  • Knowledge of Spark, PySpark, and SQL.
  • Experience with services such as Azure Data Lake, Azure Functions, Event Hubs, or Azure Data Factory.
  • Experience with Azure DevOps or GitHub Actions.
  • Knowledge of event-driven architectures.
  • Experience working with data scientists and understanding model development, validation, and deployment processes.
  • Experience industrializing algorithms or code originating from research teams.
