Job description

Описание:

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.

Задачи:

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.

Требования:

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

Условия:

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.
