Full Job Description

đź“‹ Description

  • • Build end-to-end AI-native product features that transform LLM capabilities into persistent, goal-driven workflows beyond chat-based interactions.
  • • Design agent workflows that handle multi-step planning, tool usage, failure detection, and autonomous recovery across sessions and external systems.
  • • Integrate LLMs (OpenAI, Anthropic, open-source), memory systems, and external tools into production-grade systems with reliable behavior under non-deterministic model outputs.
  • • Develop real-time AI interactions with streaming partial results, tight latency constraints, and consistent user experience despite model variability.
  • • Improve system reliability by implementing observability, fallback mechanisms, and robust error recovery for LLM and tool failures in production.
  • • Collaborate closely with ML, backend, and product teams to ship features from concept to deployment with full ownership.
  • • Iterate on product features based on real-world usage patterns, failure modes, and user feedback to increase workflow success rates.
  • • Establish scalable abstractions and patterns for integrating LLMs, persistent memory, and external APIs into the core product architecture.
  • • Optimize latency and responsiveness of AI interactions without compromising output quality or consistency.
  • • Contribute to a product experience where AI operates proactively, consistently, and dependably across long-running tasks and user sessions.
  • • Develop frontend interfaces using Next.js to visualize and interact with complex AI workflows, ensuring intuitive user control and feedback.
  • • Build and maintain backend services in Python and Node.js to orchestrate agent logic, state management, and tool execution pipelines.
  • • Containerize and deploy services using Docker and Kubernetes in a production environment with high availability and scalability requirements.
  • • Manage data storage and retrieval using both SQL and NoSQL databases to support persistent context and session continuity.
  • • Participate in a high-talent-density team that makes collective decisions, moves rapidly, and balances shipping quality work with continuous learning.
  • • Execute independently with strong ownership, bringing ambiguous product ideas to production with structure, judgment, and technical rigor.
  • • Contribute to a product vision focused on delivering practical, reliable AI benefits to billions of users globally.

🎯 Requirements

  • • Strong experience in full stack engineering (frontend + backend)
  • • Solid understanding of system design and API architecture
  • • Experience working with LLMs, RAG systems, or AI-powered applications
  • • Ability to handle ambiguity and make pragmatic engineering decisions
  • • Strong ownership — able to take features from idea to production
  • • Comfort working in fast-moving environments with evolving requirements

🏖️ Benefits

  • • Work with a high-talent-density, hands-on team building world-class AI products
  • • Collaborate on a product with the mission to bring practical AI benefits to billions globally
  • • Participate in a fast-moving environment that balances shipping quality work with learning
  • • Receive prompt interview feedback and decision-making from the technical team
