Senior Python Engineer, ManyChat

• 5+ years of commercial Python development in production environments
• Strong expertise in modern Python frameworks (FastAPI preferred; Django/Flask acceptable)
• Solid experience designing and integrating APIs (including third-party services)
• Strong understanding of async programming and concurrency (AsyncIO, non-blocking I/O)
• Experience working with PostgreSQL and large datasets
• Experience building and maintaining high-load backend systems
• Strong testing practices (unit and integration tests; PyTest preferred)
• Experience with CI/CD pipelines and Docker
• Strong ownership and product mindset — able to align with stakeholders and connect engineering work to business impact

Desirable

• 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
• Decouple and offload complexity from the core platform
• Enable scalable execution of business logic
• Provide reliable communication between services
• 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 quality: testing strategy, CI/CD, safe rollout practices
• Work closely with Platform and Product teams to align architecture with business needs
• Contribute to long-term platform scalability, not just feature delivery
