WHO WE ARE

Manychat is a leading chat marketing platform, helping businesses engage with their customers on Instagram, Facebook Messenger, WhatsApp, and Telegram. Trusted by over 1 million brands in 170+ countries, we're an official Meta Business Partner, backed by Bessemer Venture Partners. With 400+ teammates across offices in Austin, Barcelona, Yerevan, São Paulo, and Amsterdam — we're building the infrastructure of conversational commerce.

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 ideal 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 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.

TO SHINE IN THIS ROLE

You’ll need:

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.

It would be great if you have:

Experience working with loaded projects and queue systems.
Skills working with infrastructure.
Experience working with third-party API.
Knowledge of different NoSQL solutions and analytical systems.
Replication, partioning, sharding, PL/pgSQL, and other attributes of profound work with databases.

WHAT WE OFFER

We care deeply about your growth, well-being, and comfort:

Hybrid onboarding to start remotely and relocation support for you and your family.
Comprehensive health insurance for you and your family.
Professional development budget for conferences, courses, and learning resources.
Flexible benefits package tailored to your priorities.
Hybrid work and generous leave options for work-life balance.
In-office perks including free meals and snacks.
Company-funded sports activities, annual offsites, and team-building events.
