WHO WE'RE LOOKING FOR

We’re hiring a Senior Python Engineer to build and evolve a Python-based platform layer that extends and scales Manychat’s eng core.

This is not a standalone backend. This layer acts as a bridge and execution environment for high-load, business-critical workflows that cannot be efficiently handled inside the core system.

Your primary focus will be designing systems that:
- decouple and offload complexity from the core platform
- enable scalable execution of business logic
- provide reliable communication between services

This role is idóneo for someone who:
- thinks in systems, not services




- understands trade-offs of distributed architectures
- can turn loosely defined problems into stable production solutions
- is comfortable working close to platform boundaries and constraints
WHAT YOU'LL DO
- Design and build a Python-based platform layer that integrates with the core system.
- Define and evolve patterns for service communication, orchestration, and responsibility split between core and Python services.
- Develop scalable, async services handling high-load and latency-sensitive workflows.
- Own API contracts between systems, ensuring stability, backward compatibility, and clear boundaries.
- Identify and extract functionality from the core into scalable services where it improves performance or maintainability.
- Ensure reliability of cross-system interactions through observability (monitoring, logging, tracing).
- Design for failure: retries, idempotency, consistency guarantees.
- Drive engineeri
