WHO WE ARE Creating content that resonates is great — turning that attention into growth is even better. Our AI-powered automations help creators and brands engage with audiences across Instagram, Messenger, WhatsApp, and TikTok — at the right moment, with the right message, minus the manual work. We're 400+ people across three continents behind the leading platform for conversational growth, with AI skills shaping how we build, how we work, and how we grow. They'll define it. As Staff Backend Engineer for Manychat for Brands, you’ll own the technical side of a new product. You’ll set the architecture and technical priorities with the team, and decide what lives in our Python services and what stays in the PHP-based Manychat platform. It’s an individual contributor role with a lot of room to make an impact. Brands pay influencers to post but then can’t see what happens next. We’re building the first view that shows it: who asked for the link, who opened the DM, who clicked, for every campaign, creator and post. You’ll work with Product as a partner and stay close to brands and creators, so feedback reaches you fast and helps you shape Manychat for Brands. We keep Manychat running smoothly under high load every single day and make sure it's ready to scale even further. We do it by combining strong engineering foundations with AI tools that let us move faster without cutting corners. Set the architecture and technical priorities for Brands together with the Engineering Manager and the team: service boundaries, data models, authentication, access control, and integration with the core Manychat platform.



Decide which logic belongs in the Python-based Brands services and which stays in the PHP-based Manychat platform. Think about data ownership, reliability, and long-term maintenance. Explore options, split the work into measurable milestones, and plan data migrations, gradual rollouts, and rollbacks. Define reliability and performance requirements for key Brands workflows. Set metrics and observability, and check the impact of your changes on production data. Deep expertise in Python backend development and a broad view of backend architecture beyond one language. You work closely with Product Managers, challenge assumptions, and explain technical trade-offs in terms of user experience, timelines, and product capabilities. A solid understanding of distributed systems and data flows: API contracts, async processing, data consistency, retries, idempotency, and failure handling. Knowledge of how backend applications are deployed and run in production: configuration, networking, and external dependencies. Knowledge of application security basics: authentication, authorization, data isolation, and access management. Things can shift quickly here, and the team relies on everyone's proactivity and ownership.
