Backend engineer in conversational automation

Creating content that resonates is great — turning that attention into growth is even better. That's what Manychat does. 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.

• 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.
• Lead big system-level changes when the path isn't clear yet. 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.
• Find the root causes of slowdowns and repeated incidents across service boundaries, using metrics, logs, and distributed tracing.
• Work with Security, Infrastructure, and Platform teams on solutions. Decide what to fix in the application and what needs other teams, and explain the trade-offs clearly.
• Work with Product on the approach and scope of solutions, and suggest simpler options when you see them.
• Make technical decisions easy to follow: document key choices and the reasons behind them, do thorough design and code reviews, and share your knowledge in complex areas.

• Deep expertise in Python backend development and a broad view of backend architecture beyond one language. You can understand existing systems, even when the technology is new to you.
• A strong product mindset. You work closely with Product Managers, challenge assumptions, and explain technical trade-offs in terms of user experience, timelines, and product capabilities.
• Experience owning the architecture and production operations of a product or a large technical area, not only delivering separate features.
• 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.
• Comfort in a fast-changing environment. Things can shift quickly here, and the team relies on everyone's proactivity and ownership.
• Strong English for technical and product discussions and for documentation.
• Будет плюсом: Hands-on PHP experience, on top of understanding how our Python and PHP systems work together; Experience with ETL/DWH pipelines and analytics systems; Experience with environment configuration, CI/CD, and Infrastructure as Code; Experience improving AI-assisted software development practices

• Hybrid onboarding to start work remotely and relocation support for you and your family.
• Comprehensive health insurance for both you and your family.
• Professional development budget for conference tickets, online courses, and other relevant resources to help you grow.
• Flexible benefits package: no one-size-fits-all perks here. You get a budget and you decide where it goes, from health and wellbeing to family and setting up your home office.
• Hybrid work and generous, flexible time off — planned with your team, not rationed by a rigid quota.
• In-office perks, including free meals and snacks.
• Company-funded sport activities, annual offsites and team-building events.
• AI isn't a perk here — it's how we work. Claude, OpenAI, and more are on by default from day one, and we back teams in adopting whatever makes them faster.
