• Design, develop and maintain scalable web applications, working on both frontend and backend • Lead technical decisions and define architectures (modular monoliths, microservices, REST/GraphQL APIs) • Develop and maintain robust backend services using Node.js/NestJS, ensuring performance and security • Implement and manage caching strategies (Redis, CDN, distributed cache) to achieve high performance • Create and integrate internal and external APIs, ensuring data consistency and reliability • Work with distributed systems and messaging (Pub/Sub, queues, asynchronous processing) • Ensure code quality through automated testing, code reviews and best practices (SOLID, Clean Architecture) • Collaborate with product, design and engineering teams to define and deliver solutions • Monitor applications using observability tools (logs, metrics and tracing) • Enforce security best practices, authentication and data protection • Mentor less experienced developers and act as a technical reference within the team • Document architectures, flows and technical decisions

• Implement robust measurement and observability. • Build video recording pipeline for T&S and user experience • Develop initial seller tools for enhanced livestream interaction. • Advance our video features for flawless user experiences. • Inform long term video strategy including framework success criteria and creation • Lead the innovation in seller tools, enabling peak streaming performance. • Evaluate and onboard new video providers.

• Use AI-assisted development tools, including Claude Code, to accelerate implementation while validating correctness, security, and performance. • Design and build server-side APIs that authenticate users, accept and manage backups, handle large-scale data operations, and prepare restored data for customers across our global user base. • Collaborate with Product, QA, and Support teams to ensure both backend features reflect real customer workflows and usage patterns. • Build and maintain support tooling to help diagnose and resolve customer issues at scale. • Ensure all code and open source assets meet high standards for testing, documentation, reproducibility, and developer usability.
