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

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
