Senior Python Engineer (Async & AWS Focus)

We are looking for a highly skilled Python Engineer to join our backend infrastructure team. You will be responsible for designing and maintaining high-concurrency systems, leveraging asynchronous programming patterns to ensure optimal performance and scalability. This role requires a deep understanding of the Python ecosystem, specifically focusing on non-blocking I/O and event-driven architectures. Your daily responsibilities will involve architecting robust backend services deployed on AWS. You will work closely with cross-functional teams to migrate legacy components to modern, cloud-native solutions using services like Lambda, ECS, and SQS. Beyond Python, you will be expected to contribute to our broader backend stack, ensuring seamless integration between microservices and data persistence layers. Proficiency in both English and Spanish is essential, as you will be collaborating with distributed teams across different time zones. The ideal candidate brings over five years of professional experience in backend development. You should be comfortable navigating complex distributed systems, debugging performance bottlenecks in asynchronous code, and implementing best practices for cloud security and infrastructure as code. We value engineers who can communicate technical trade-offs clearly and mentor junior team members in a collaborative, agile environment.
