Job Title - Sr. FullStack .AI Engineer - REMOTE

Duration:6 months

 

Job Description:

 

Top 3 skills required for this role:

 

1. Hands-on experience with GitHub Spec Kit and spec-driven development using AI agents (/specify, /plan, /tasks workflow).

2. Production-grade applications built with React / JavaScript frameworks and Node.js REST/GraphQL APIs.

3. AWS infrastructure (Lambda, S3, EC2, API Gateway) paired with MongoDB and/or PostgreSQL at scale.

 

Job Description/ Responsibilities

 

• Lead spec-first development initiatives using GitHub Spec Kit — authoring specs, technical plans, and agent-ready task breakdowns before writing any code.

• Design and build full stack web applications using React, JavaScript/TypeScript frameworks, and Node.js, from UI to backend API layer.

• Develop, integrate, and maintain RESTful and GraphQL APIs, ensuring performance, reliability, and security across services.

• Architect and deploy cloud-native solutions on AWS (Lambda, EC2, S3, API Gateway, RDS, CloudFormation) with a focus on scalability and cost efficiency.

• Build and integrate AI-powered features — leveraging LLMs, AI agents, prompt engineering, and the GenAI ecosystem to enhance product capabilities.

• Design and manage relational (PostgreSQL) and document (MongoDB) databases, including schema design, query optimisation, and data migrations.

• Collaborate with product managers, designers, and AI/ML engineers to translate requirements into well-specified, shippable software.

• Participate in code reviews, establish engineering best practices, and contribute to a culture of quality and continuous improvement.

 

 

Required Qualifications

 

• 5+ years of professional experience in full stack software development.

• Proven hands-on experience with GenAI tools and a spec-first development approach, including GitHub Spec Kit or equivalent workflows.

• Strong proficiency in React and modern JavaScript / TypeScript frameworks (Next.js, Vue, or similar).

• Solid backend development skills with Node.js — building and maintaining production REST or GraphQL APIs.

• Experience deploying and operating applications on AWS — comfortable with core services such as Lambda, EC2, S3, API Gateway, and RDS.

• Practical experience with both MongoDB (document store) and PostgreSQL (relational), including schema design and query tuning.

• Familiarity with AI agent frameworks, LLM APIs (OpenAI, Anthropic, or similar), and prompt engineering techniques.

• Strong understanding of software engineering fundamentals — data structures, system design, testing, and CI/CD practices.

• Bachelor’s degree in computer science, Engineering, or equivalent practical experience.
