Principal Full - stack Engineer (node.js & Typescript)

Senior Full-Stack Engineer

We are looking for a Senior Full-Stack Engineer with a strong foundation in back-end development using Node.js (and modern frameworks such as NestJS, Hono or Bun) and a solid grasp of front-end engineering in TypeScript (using frameworks like React or Angular). This role emphasizes back-end architecture, API development, and integration of AI-powered features, while also requiring the ability to deliver polished, responsive user interfaces. You will contribute across the stack to build scalable, secure, and maintainable software systems that power modern, intelligent applications for our clients.

Key Responsibilities:

• Backend Architecture & Development: Design and implement robust, modular, and cloud-ready back-end services using Node.js (TypeScript) with clear separation of concerns.
• API Design & Integration: Develop and maintain RESTful APIs (and occasional GraphQL endpoints) that enable seamless communication between backend and front-end.
• AI Integration & Prompt Chaining: Incorporate AI capabilities by integrating third-party AI/LLM APIs (e.g. OpenAI) and implementing light prompt chaining.
• Database Design & Interaction: Work with relational and NoSQL databases for data persistence and optimization.
• Event-Driven Systems: Integrate asynchronous messaging or streaming systems (such as RabbitMQ or Kafka) into the architecture.
• UI Development: Build responsive, accessible, and user-friendly front-end interfaces using React or similar frameworks.
• Styling & Responsiveness: Use modern HTML5/CSS3 and responsive design principles to implement layouts that work well on various screen sizes.
• Frontend-State & API Consumption: Handle client-side state management and integrate front-end with back-end and AI services.
• Cross-Functional Collaboration: Work closely with designers, product managers, DevOps engineers, and data scientists to deliver end-to-end solutions.
• Cloud-Ready Development & DevOps: Contribute to deployment pipelines, containerization, and cloud deployments using Docker and CI/CD pipelines.
• System Design & Code Reviews: Participate in architectural discussions, conduct code reviews, and mentor peers.
• Testing & Quality Assurance: Write and maintain unit, integration, and end-to-end tests to ensure reliability and performance.
• Mentorship & Best Practices: Mentor junior developers, lead by example, and drive best practices across the team.
