About the Role
We're looking for a Full-Stack Engineer to build our web application end-to-end and bring the MVP to life. You'll own the user-facing product and the backend that supports it, working closely with the AI Engineer to weave intelligent, real-time AI interactions into a smooth, reliable experience.
What You'll Do
Build and ship the web application across frontend and backend, from UI components to APIs and data models
Design and implement a responsive, real-time conversational interface (React, WebSockets/SSE)
Develop backend services: authentication, session management, data persistence, and third-party integrations
Integrate AI and multi-agent services into the product in partnership with the AI Engineer
Design and maintain databases and API contracts that scale with product complexity
Own performance, reliability, and security across the stack
Translate product and design requirements into well-tested, maintainable features
Move fast in an early-stage environment, balancing speed with quality
4+ years of full-stack software engineering experience
Strong proficiency in TypeScript/JavaScript and a modern frontend framework (React preferred)
Solid backend experience (Node.js, Python, or similar) building and consuming APIs
Experience designing relational and/or NoSQL data models (PostgreSQL, MongoDB, etc.)
Familiarity with real-time communication patterns (WebSockets, SSE) and streaming UIs
Understanding of authentication, authorization, and secure data handling
Experience integrating third-party APIs, ideally including LLM or AI services
Comfort owning features end-to-end with minimal oversight
Experience building with LLM APIs or AI-powered product features
Familiarity with cloud platforms (AWS/GCP/Azure) and CI/CD pipelines
Knowledge of caching, queuing, and background job processing
Prior early-stage startup or 0-to-1 product experience
