About the Project

Today, over 5 billion people use basic applications like email, notes, and tasks that were not built as AI-native tools. Our mission is to build a **proactive smart assistant** for everyday users, bringing intelligence to conversations, errands, organization, and daily workflows with minimal prompting.

Our product focuses on high reliability for long-running workflows, persistent context, and real-world task completion. We tackle multi-step reasoning, external tool integration, and model predictability. Our target is to help users complete daily tasks with over **~90% reduced time**, creating an experience that feels truly magical.

We are a lean, world-class team with high talent density. We make decisions rapidly, strike a balance between high-quality output and fast iteration, and give our engineers the autonomy to execute independently.

* **End-to-End Product Engineering:** Build features across the frontend, backend, and AI integration layers. * **Agent Architecture:** Design agent workflows that effectively handle multi-step planning, tool execution, failure modes, and self-recovery. * **Real-time AI Interactions:** Engineer responsive systems utilizing streaming, partial results, and tight latency constraints. * **System Reliability & Observability:** Integrate LLMs, memory, and third-party tools into systems that perform consistently under real-world conditions. * **Continuous Iteration:** Build robust fallback mechanisms and continuously improve system success rates based on evaluation metrics and user telemetry.

* **Strong Full Stack Experience:** Proven background building end-to-end features across frontend and backend stacks. * **System Design & APIs:** Solid understanding of API architecture, data flow, and distributed system fundamentals. * **AI/LLM Experience:** Hands-on experience working with LLMs, RAG architectures, or AI-powered features in production. * **High Ownership:** Ability to take feature ownership from initial concept through design to production deployment. * **Pragmatic Mindset:** Comfortable making clear engineering choices in fast-moving, evolving environments.

* **Employment Contract (UoP):** Stable employment with standard statutory benefits. * **100% Remote Work:** Complete flexibility to work from anywhere. * **High Impact:** Opportunity to shape an AI-native product reaching global scale. * **Streamlined Culture:** High autonomy, low friction, and quick decision-making.
