We’re servicing a client looking for a Full Stack Engineer to join the early product team and help shape the foundation of a product category that’s never existed before. You’ll work across the frontend and backend, integrate large language model (LLM) capabilities, and collaborate closely with mobile and AI specialists to deliver a seamless, cross-platform experience.

This is an opportunity to make a direct impact from the ground up, contributing to both the technical direction and the product’s core identity.

Role Responsibilities

• Develop and maintain end-to-end web applications using React / Next.js on the frontend and NestJS on the backend.

• Architect and optimize GraphQL APIs and ensure smooth data flow between PostgreSQL and other systems.

• Integrate AI and LLM endpoints into backend workflows to enable automation and intelligent user interactions.

• Partner with mobile engineers (React Native) to align backend services and ensure a unified product experience across devices.

• Collaborate with product managers, designers, and AI engineers to translate new features from concept into production-ready code.

• Implement and manage third-party integrations such as document verification, payments, identity (KYC), and data storage.

• Adhere to security best practices, especially around document management, user authentication, and performance optimization.

• Contribute to CI/CD pipelines, participate in code reviews, and promote consistent coding standards across the team.

Qualifications & Skills

• 2+ years of hands-on experience building modern web applications using TypeScript with React or Next.js.

• Strong understanding of NestJS, GraphQL, and relational databases such as PostgreSQL.

• Practical experience integrating AI or machine learning APIs (LLMs, inference models, or automation services).

• Knowledge of secure authentication systems (OAuth, JWT) and cloud-based deployment (AWS or equivalent).

• Exposure to mobile development workflows, ensuring backend compatibility with React Native or similar frameworks.

• Familiarity with DevOps practices, including Git-based version control, continuous integration, and automated deployment.

• Commitment to high-quality UX, maintainable architecture, and a user-centric mindset.
