About the Role:
We are looking for a skilled Full Stack Developer who can take full ownership of application development, deployment, and optimization. You will lead the migration of an existing Elixir/Phoenix-based application into a modern React + Node.js stack.
This is a hands-on engineering role that requires technical leadership, autonomy, and a strong understanding of cloud-based deployment and AI integration.
Key Responsibilities:
- Lead the migration of an existing platform from Elixir/Phoenix to React + Node.js + PostgreSQL.
- Build scalable, user-friendly front-end applications using React.js.
- Develop robust backend services using Node.js (Express, Nest, or an equivalent framework).
- Integrate with AI services such as OpenAI, Claude, or Gemini for advanced product capabilities.
- Deploy applications using GCP and manage infrastructure (CI/CD, hosting, environment setup).
- Work with both SQL and NoSQL databases, including PostgreSQL and Firestore.
- Collaborate with internal stakeholders to ensure best practices in full-stack architecture and deployment.
Must Haves:
- React.js – Proven experience building interactive front-end applications.
- Node.js – Experience with frameworks like Express or Nest.js and ability to justify technical choices.
- AI API Integration – Familiarity with implementing external LLM APIs (e.g., OpenAI, Claude, Gemini).
- SQL & NoSQL – Strong experience with PostgreSQL and document-based databases (e.g., Firestore).
- GCP – Hands-on experience deploying/managing applications in Google Cloud Platform.
- Firebase / Firestore – Comfortable integrating Firebase services.
- DevOps Ownership – Capable of handling deployments, CI/CD pipelines, and cloud hosting.
Nice to have:
