Sound like your next challenge? Let’s talk!
YOUR FUTURE TEAMMATES 👋
We run Manychat under serious load, every day, and get it ready to handle even more. The stack is built for speed and durability, and we're already working at the front of the AI era, not scrambling to catch up. We're the ones who shape and own what gets built. You'll do that work alongside a team that already moves fast, holds a high bar, and has each other's backs when it counts.
WHAT YOU'LL DO 🚀
Design and build Billing's Python foundation: the environment where product features and the existing PHP backend work together.
Set the direction while there's no roadmap yet: experiment, make architectural decisions on your own, and design systems end to end.
Build async services for billing workflows: payments, payment provider integrations, invoicing, anti-fraud, and local regulatory compliance.
Design and integrate APIs, both internal and third-party, with clear and stable contracts.
Build for failure: retries, idempotency, consistency, and observability, so every payment is handled correctly.
Set the testing, CI/CD, and rollout practices this layer runs on, so the team can maintain, extend, and scale it after you.
Mentor and set the technical bar for the two mid-level engineers who join after you.
Work with cross-functional partners, so your technical decisions fit how the business actually runs.
Help Billing support the business as it scales and as new products and ventures launch on top of Manychat..
TO SHINE IN THIS ROLE 💥
You'll need
6+ years of commercial Python development in production, with Python as your primary language and recent hands-on work.
Strong expertise in modern Python frameworks (FastAPI preferred; Django or Flask are fine).
Solid experience designing and integrating APIs, including third-party services.
Strong understanding of async programming and concurrency (AsyncIO, non-blocking I/O).
Experience with PostgreSQL and large datasets.
Experience building and maintaining backend systems under production load, designed to last.
Strong testing practices (unit and integration tests; PyTest preferred) and experience with CI/CD pipelines and Docker.
Strong engineering judgment: you design systems end to end and make architectural decisions on your own.
Mentoring or leadership experience of any kind.
Experience working in cross-functional teams, with clear communication and the ability to adapt when things change.
It would be great if you have
Experience with billing, invoicing, or payment systems.
Experience with PHP.
A product mindset and scale-up experience.
Experience with queues, NoSQL, or analytical systems.
Deep database experience, such as replication, partitioning, sharding, or PL/pgSQL.
