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 adecuado 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 engineering qu
