Build the AI Companionship Platform the World Actually Needs

At everfriends.ai, we’re reimagining what meaningful digital companionship looks like. We’re not building another chatbot—we’re building emotionally intelligent, memory-driven AI companions that feel consistent, safe, and human-centered.

As a Full Stack Developer, you will play a foundational role in designing and building the systems powering a next-generation AI experience across web, mobile, and cloud infrastructure.

You’ll work directly alongside a founder who blends product vision with hands-on execution and moves quickly from idea to implementation. If you thrive in environments where ownership is real, feedback is direct, and your code meaningfully impacts people’s lives, this is your kind of challenge.

Why You Are Going to Love This Job

  • Build something emotionally significant. This isn’t just SaaS—it’s technology designed to combat loneliness and foster connection.

  • Real ownership. You’ll influence architecture, product direction, and user experience decisions.

  • AI-first environment. Work at the intersection of LLMs, memory systems, personalization engines, and scalable distributed systems.

  • Ship across platforms. Web, iOS, Android, APIs, and backend infrastructure—all connected.

  • Lean team, high impact. Your work ships fast and directly reaches users.

  • Modern stack. JavaScript/TypeScript ecosystems, cloud-native services, mobile integration, and DevOps automation.

What You’ll Do

  • Architect and build end-to-end features across frontend, backend, and mobile platforms.

  • Develop modern web applications using JavaScript, TypeScript, React, and Next.js.

  • Design and implement scalable APIs, webhooks, and event-driven services supporting real-time AI interactions.

  • Build backend services using Node.js, Python, or comparable frameworks.

  • Integrate and orchestrate LLM providers, AI APIs, and memory systems that improve personalization over time.

  • Support and extend iOS and Android experiences (React Native, Flutter, or native integrations).

  • Implement authentication, messaging, notifications, and real-time streaming experiences.

  • Own backend infrastructure, deployment pipelines, and cloud environments.

  • Establish DevOps best practices including CI/CD, monitoring, logging, and automated deployments.

  • Optimize performance, scalability, reliability, and security as the platform grows.

  • Collaborate on product strategy, architecture decisions, and technical roadmap planning.

What You Bring

  • Strong full stack development experience using JavaScript and TypeScript.

  • Experience building modern frontend applications (React, Next.js, or similar).

  • Backend development experience with Node.js, Python, or comparable frameworks.

  • Proven experience designing REST APIs, GraphQL APIs, webhooks, and integrations.

  • Experience deploying and operating systems in cloud environments (AWS, GCP, Azure, or similar).

  • Familiarity with mobile application development for iOS and Android environments.

  • Understanding of DevOps practices: CI/CD pipelines, containerization, infrastructure automation, and observability.

  • Experience integrating external APIs and AI services (LLMs, embeddings, conversational systems).

  • Solid system design knowledge including databases (SQL + NoSQL) and scalable architectures.

  • Comfort operating in fast-moving startup environments.

  • A strong product mindset—you care how users feel using what you build.

  • Bias toward action. You ship.
