Original job description

About Co-Intelligence Labs We're a well-funded AI startup in stealth mode building intelligent platforms that transform healthcare decision-making for seniors. Our mission is to make complex healthcare navigation effortless through AI-powered recommendations and conversational interfaces that are secure, scalable, and accessible to everyone.

About the Role As a Fullstack Engineer, you'll own the complete technology stack of our next-generation healthcare recommendation platform. You'll build everything from elegant frontends to robust backends, integrate cutting-edge AI features, and deploy scalable solutions that help users discover optimal healthcare plans through natural AI conversations. This role offers end-to-end ownership in a modern monorepo environment, working with technologies like Next.js, React Native, NestJS, AWS, and various AI services. You'll collaborate closely with designers, AI specialists, and product teams to rapidly prototype and refine features based on user insights. Location: Austin, TX (relocation assistance provided)

In this role, you will:

Lead fullstack development across web (Next.js/React + Tailwind), mobile (React Native/Expo), and backend (NestJS) in an Nx monorepo environment
Integrate AI features to create immersive conversational user experiences across text and voice interfaces
Build secure data systems
Manage deployments in AWS with tools like ECS Fargate, Docker, Terraform, ElastiCache, and Datadog
Develop robust APIs for chat messaging, AI assistant orchestration, user account management, with rate limiting and error handling
Collaborate cross-functionally to define roadmaps, experiment with AI capabilities, and adapt to evolving requirements
Optimize using data insights through visualization, A/B testing, and performance tuning to improve user engagement

You might thrive in this role if you:

Have comprehensive fullstack experience from frontend design to backend architecture, database optimization, and cloud deployment
Are experienced with AI engineering and cutting-edge AI integration techniques
Know the TypeScript ecosystem well, including Next.js 15/React 19, NestJS/Node.js, React Native/Expo, Prisma/RDS, and tools like Nx/PNPM/Docker/AWS ECS
Have built complex interactive apps such as real-time chat systems, recommendation engines, or data-rich profile management systems
Think like a product person - you empathize with users, prototype quickly, and make smart trade-offs to ship value in fast-paced environments
Care about AI's positive impact in healthcare while maintaining focus on ethics, privacy, and inclusive user experiences
Communicate effectively across teams, translating technical concepts into actionable insights for engineers, designers, and stakeholders
Enjoy playing with new technologies - we’re all pushing the envelope with how we develop products and we expect you to do the same

About the Company Co-Intelligence Labs is an equal opportunity employer dedicated to using AI to solve pressing human challenges, starting with healthcare navigation. We're committed to building AI systems that prioritize safety, user empowerment, and diverse perspectives to benefit society broadly. We pay above market for startups and offer generous equity compensation.
