Senior Python Platform Engineer - Billing & Accounts

Manychat; Amsterdam; Hybrid; EUR 90,000 - 140,000; Full time

Job summary

Manychat is seeking a Senior Python Engineer to design and evolve a Python-based platform layer that scales the eng core and enables high-load workflows. You will focus on decoupling complexity from the core, enabling scalable business logic, and ensuring reliable inter-service communication.

You will own API contracts, drive testing and CI/CD practices, and work closely with Platform and Product teams to deliver scalable, production-ready solutions at scale.

Qualifications

• 5+ years of commercial Python development in production environments.
• Strong experience with modern Python frameworks (FastAPI preferred; Django/Flask acceptable).
• Experience designing and integrating APIs with third-party services.
• Solid understanding of async programming (AsyncIO).
• Experience with PostgreSQL and large datasets.
• Experience building and maintaining high-load backend systems.
• Strong testing practices (PyTest).
• Experience with CI/CD pipelines and Docker.

Responsibilities

• 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.
