Strong written and oral communication is essential, as the candidate will regularly collaborate with diverse teams across the enterprise to design, deliver, and iterate on AI-powered solutions.

Responsibilities

• Analyze business and technical requirements and propose robust solutions for delivering AICOE projects within expected parameters of cost, time, and quality, with a focus on Generative AI and full-stack engineering outcomes.
• Design, develop, and maintain scalable web applications and AI-powered platforms using modern web technologies (e.g., React, FastAPI, Node.js) and LLM integration frameworks, ensuring performance, scalability, and reliability.
• Create and manage databases, ensuring data integrity and security.
• Write clean, well-documented, and thoroughly tested code, taking full ownership of unit and integration testing for all functions created or modified, in accordance with AICOE coding standards and quality guidelines.
• Work with project managers to compile a work breakdown structure of tasks for a given deliverable and provide realistic estimates for completing the assignment.
• Collaborate with other Developers and QA Engineers to execute full cycle integration, functional, and regression testing.
• Continuously evaluate and improve system performance, reliability, and maintainability; proactively identify and propose better technical approaches as the AICOE platform evolves.
• Engage effectively with business and operations teams to understand requirements, resolve design challenges, and ensure that AI/ML solutions are aligned with enterprise goals and operational needs.
• Implement user-friendly and responsive front-end interfaces.
• Develop RESTful APIs and integrate third-party services, including LLM and Generative AI APIs (e.g., Anthropic, OpenAI, Azure OpenAI), to extend AICOE platform capabilities.
• Ensure cross-platform optimization for mobile and desktop.
• Maintain code quality, organization, and automation.
• Participate in code reviews and provide constructive feedback to peers.
• Stay current with the rapidly evolving Generative AI and LLM landscape; actively exercise Applied AI Expertise by using tools such as Claude Desktop, Claude CLI, Claude Code, Cursor, Microsoft Copilot, and Google Gemini in day-to-day development, and share knowledge and best practices with the broader AICOE team.

Knowledge and Experience

• Bachelor's or Master's degree in Computer Science, Electrical Engineering, Information Sciences, or a related field; equivalent professional experience with a strong portfolio of AI/ML or full-stack development work will also be considered.
• Strong, proven programming skills in at least one general-purpose programming language such as JavaScript, Python, Java, or C#.
• Proficiency in front-end frameworks (e.g., React, Angular, Vue.js) and back-end frameworks (e.g., FastAPI, Node.js, Spring).
• Working knowledge of SQL and experience with relational databases (e.g., PostgreSQL, MySQL).
• Familiarity with NoSQL databases (e.g., MongoDB, Cassandra) is a plus.
• Experience in data visualization and business analytics tools like Tableau, Microsoft PowerBI, or similar tools is beneficial.
• Experience in cloud platforms such as AWS, Azure, or Google Cloud.
• Experience with containerization and orchestration tools like Docker and Kubernetes.
• Experience working in Agile teams comprised of 5-8 cross-skilled engineers.
• Solid understanding of version control tools (ideally Git).
• Experience in applying web development best practices and implementing RESTful APIs.
• Experience with writing complex programs and implementing custom algorithms.
• Experience beyond using open-source tools as-is, and writing custom code on top of, or in addition to, existing open-source frameworks.
• Knowledge of continuous integration and continuous deployment (CI/CD) pipelines.
• Excellent written and oral communication skills, with the ability to explain complex AI/ML and technical solutions clearly to stakeholders across multiple disciplines; comfortable working in a diverse, globally distributed team.
• Experience working in an applied R&D or innovation-lab environment, operating with agile practices and a bias for rapid iteration; demonstrated Applied AI Expertise including hands-on use of agentic developer tools (e.g., Claude Desktop, Claude CLI, Claude Code, Cursor, Microsoft Copilot, or Google Gemini) and working knowledge of prompting techniques is strongly preferred.
