API Design & Integration: Build and maintain well-documented APIs that connect front-end applications with backend services and third-party LLM providers.
CI/CD & Deployment: Contribute to continuous integration and continuous delivery pipelines to streamline code deployment, testing, and release cycles for web applications.
Cloud Deployment: Deploy and maintain web applications and backend services in cloud environments (AWS and/or Azure), ensuring high availability, security, and cost efficiency.
Security & Compliance: Collaborate with the cybersecurity team to embed best practices into the development lifecycle, including secrets management, secure API design, vulnerability scanning, and compliance automation.
Bachelors and nine (9) years or more experience; Masters and seven (7) years or more experience ; PhD or JD and four (4) years or more experience.
