That's what Manychat does.\nOur 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.\nWe'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.\nWHO WE'RE LOOKING FOR\nYour decisions here won't get lost in a big system. They'll define it.\nAs 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.\nThe product fills a real gap. 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.\nYou’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.\nSound like you? Let’s talk!\nYOUR FUTURE TEAMMATES\nMeet the Engineering team:\nWe 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. And we're the ones who shape and own what gets built. AI accelerates. Humans own the thinking.\nWHAT YOU'LL DO\nSet 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.\n\nDecide 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.\n\nLead 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.\n\nDefine reliability and performance requirements for key Brands workflows. Set metrics and observability, and check the impact of your changes on production data.\n\nFind the root causes of slowdowns and repeated incidents across service boundaries, using metrics, logs, and distributed tracing.\n\nWork 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.\n\nWork with Product on the approach and scope of solutions, and suggest simpler options when you see them.\n\nMake 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.\n\nTO SHINE IN THIS ROLE\nYou'll need:\nDeep 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.\n\nA 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.\n\nExperience owning the architecture and production operations of a product or a large technical area, not only delivering separate features.\n\nA solid understanding of distributed systems and data flows: API contracts, async processing, data consistency, retries, idempotency, and failure handling.\n\nKnowledge of how backend applications are deployed and run in production: configuration, networking, and external dependencies.\n\nKnowledge of application security basics: authentication, authorization, data isolation, and access management.\n\nComfort in a fast-changing environment. Things can shift quickly here, and the team relies on everyone's proactivity and ownership.\n\nStrong English for technical and product discussions and for documentation.\n\nIt would be great if you have:\nHands-on PHP experience, on top of understanding how our Python and PHP systems work together.\n\nExperience with ETL/DWH pipelines and analytics systems.\n\nExperience with environment configuration, CI/CD, and Infrastructure as Code.\n\nExperience improving AI-assisted software development practices.\n\nOur tech stack: Python, FastAPI, Pydantic, SQLAlchemy, PostgreSQL, Redis, and Celery. Our services integrate with Manychat's PHP-based platform. Everything runs on AWS and Kubernetes, with Terraform/Terragrunt for infrastructure. You don't need hands-on experience with every tool. Technical depth and the ability to reason about complex systems matter most.\nWHAT WE OFFER\nWe care deeply about your growth, well-being, and comfort:\nHybrid onboarding to start work remotely and relocation support for you and your family.\n\nComprehensive health insurance for both you and your family.\n\nProfessional development budget for conference tickets, online courses, and other relevant resources to help you grow.\n\nFlexible 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.\n\nHybrid work and generous, flexible time off - planned with your team, not rationed by a rigid quota.\n\nIn-office perks, including free meals and snacks.\n\nCompany-funded sport activities, annual offsites and team-building events.\n\nAI 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.\n\nManychat is an Equal Opportunity Employer.
