We are seeking a Python Specialist with strong experience building high-performance, scalable applications and developer tooling. This is a fully on-site role, requiring daily presence at our office located at Av. Angélica, 2197.

  • Python agentic development (AI-related flows and automation).
  • Creating API wrappers and integration layers.
  • Developing command-line utilities using argparse, enabling automation and developer productivity workflows.
  • Designing and training ML models using TensorFlow, including data pipelines and inference optimization.
  • Architecting asynchronous workflows with asyncio, leveraging async/await patterns and for concurrent execution.
  • Writing high-quality, maintainable tests using pytest, including mocks, fixtures, and async test strategies.
  • Evaluating algorithmic efficiency with strong understanding of time complexity and data structures.
  • Contributing to next-generation API communication patterns, with familiarity in tRPC or schema-driven RPC frameworks.

What Makes You a Great Fit

  • Deep knowledge of modern Python (5+ years) and industry best practices.
  • Experience architecting async systems and optimizing network-bound workloads.
  • Ability to move comfortably across ML, backend services, testing, and developer tooling.
  • Strong debugging skills and a pragmatic approach to performance and reliability.
  • Ability to translate complex technical requirements into clean, reusable abstractions.
  • English fluency is essential.

Nice to Have

  • Experience containerizing Python applications.
  • Exposure to typed Python environments (mypy, pydantic, dataclasses).
  • Understanding of distributed systems and message-driven architectures.
