WHO WE ARE
We help creators get more out of every conversation with Instagram-focused automations and support for other channels like Messenger, WhatsApp, and TikTok. The result? Better engagement, more sales, and real, sustainable growth. With a diverse team of 350+ people across three continents, we’re building the leading Chat Marketing platform - trusted by more than 1.5 million customers worldwide. AI is one of our top strategic priorities. We’re building intelligent, production-grade systems that power conversations at scale - and we’re just getting started.
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 (monitori
