Position Overview

We are seeking a Full Stack Software Engineer (Python & Modern JavaScript Frameworks) to design, build, and support modern web applications that enable mission-critical internal systems. Web application development is a required core skill for this role. This position is heavily focused on Python backend engineering, combined with professional experience building front-end web interfaces using frameworks such as React, Vue, or Angular. You will develop and enhance a chat-based internal application, ensuring it is secure, scalable, and maintainable. While the application integrates with AI tools, AI/ML experience is not required-the focus is delivering production-grade full-stack web applications.

• Build responsive, intuitive front-end web applications using React, Vue.js, or Angular. (Web application UI development is required.)
• Implement secure web authentication and authorization frameworks (JWT, OAuth2).
• Collaborate with DevOps teams to create and maintain CI/CD pipelines for cloud-based web deployments to Azure (preferred), AWS, or Google Cloud Platform.
• Write clean, maintainable, and well-tested code that follows modern web engineering best practices.
• Participate in code reviews, agile ceremonies, and cross-team collaboration to ensure high-quality, timely delivery.
• Monitor and optimize web application performance, logging, and observability.
• Produce and maintain technical documentation, including web architecture diagrams and operational processes.

Required Qualifications

• 7 years of professional software engineering experience, with 4 years of Python-based web application development (FastAPI, Flask).
• Strong proficiency in building modern front-end web applications using React (preferred), Vue, or Angular. (Web UI experience is required.)
• Solid understanding of OOP, asynchronous programming, REST API design, and web application data modeling.
• Experience deploying and supporting web applications in cloud environments (Azure preferred; AWS/Google Cloud Platform acceptable).
• Hands-on experience with GitHub, CI/CD automation, and Docker for web deployments.
• Strong communication skills, problem-solving ability, and attention to detail.

Preferred Qualifications

• Familiarity with Node.js or additional backend web frameworks.
• Experience with microservices, Kubernetes, or infrastructure-as-code tools (Terraform, CloudFormation).
• Knowledge of relational and NoSQL databases (PostgreSQL, MySQL, MongoDB).
• Exposure to AI/ML frameworks (OpenAI, LangChain, Hugging Face)-not required but beneficial.
• Experience in public sector, enterprise, or regulated web application environments.
• Bachelor's or Master's degree in Computer Science, Engineering, or a related field.
