Senior Full‑Stack Engineer - Planning Solutions

Role Description As a Senior Full-stack Engineer, you will build production-grade systems that go well beyond conversational assistants. This role sits at the intersection of software engineering, data engineering, and Agentic engineering, building stateful, goal-driven AI systems that can reason, plan, coordinate, and execute complex tasks with appropriate controls. You will collaborate closely with colleagues across Product, Design, Infrastructure, and other Application engineers. You will help enforce sound engineering practices, and ensure our AI-driven applications remain robust, maintainable, and performant. You must demonstrate a strong understanding of cloud architecture principles. Primary Responsibilities: Build High-Quality SPA: Design, develop, test, and maintain Single Page Applications ranging from experiments to flagship products. Build High-Quality Backend Systems: Design, develop, test, and maintain backend services and APIs that power AI applications, ensuring they are reliable, secure, and performant. Design and build multi-agent workflows: Build stateful agentic applications using agent orchestration frameworks capable of coordinating multiple autonomous components. State, memory, and long-running execution: Engineer control flows for non-deterministic systems, including message passing, persistent memory, recoverability, and interruptible execution for long-running tasks. Standardized tool interfaces: Establish universal interfaces between agents, enterprise data sources, and operational tools to ensure modularity, reusability, and consistent governance. Model integration and runtime optimization: Build routing and fallback strategies across multiple model endpoints; optimize context management, latency, and inference cost while maintaining reliability. Production deployment: Package and deploy workloads via containerization and cluster orchestration, using cloud-native services for scaling, isolation, and secure runtime operations.
