· Establish and enforce development standards, coding best practices, and architectural patterns.

· Design and implement AI-enabled application features (e.g., LLM integrations, intelligent search, automation workflows).

· Integrate solutions with AI APIs such as Azure OpenAI or AWS Bedrock.

· Ensure responsible use of AI technologies including governance, security, and data privacy.

· Serve as a primary technical interface with clients and stakeholders.

· Translate business requirements into scalable technical solutions.

· Lead architecture discussions, solutioning sessions, and technical briefings.

· Oversee development of secure, high-performance web applications and RESTful APIs.

· Ensure interoperability and cross-platform integration.

· Drive API design, versioning, and performance optimization.

· Architect and deploy applications in AWS and/or Azure environments.

· Lead CI/CD pipeline implementation and DevSecOps practices.

· Optimize performance, scalability, and cost efficiency.

· Mentor and guide developers across multiple technology stacks.

· Lead code reviews, technical decision-making, and architecture governance.

· Foster a culture of innovation and continuous improvement.

· Ensure applications meet modern security and compliance standards.

· Implement testing strategies and performance monitoring.

Core Qualifications:

·        Bachelor’s or Master’s degree in Computer Science, Information Technology, or related field (or equivalent experience).

·        8+ years of experience in full-stack web application development.

·        Strong experience with .NET/C# and modern JavaScript frameworks (React, Angular, or Vue).

·        Experience working across additional technologies such as Node.js, Python, or similar.

·        Hands-on experience with T-SQL, including stored procedures, triggers, and query optimization.

·        Strong experience with AWS and/or Azure cloud platforms, including serverless architectures.

·        Experience designing and building RESTful APIs and microservices architectures.

·        Demonstrated experience integrating AI/ML capabilities or AI APIs into applications.

·        Knowledge of secure application development and cloud security best practices.

·        Proven ability to lead projects and communicate effectively with technical and non-technical stakeholders.

·        U.S. Citizenship required.

·        Ability to obtain and maintain Public Trust clearance.

Preferred Qualifications:

·        Cloud or AI certifications (AWS, Azure, or AI/ML-related).

·        Experience building or integrating generative AI solutions in production environments.

·        Familiarity with Python for AI/ML workflows.

·        Experience with DevSecOps practices and CI/CD automation tools.

·        Prior experience in a client-facing technical leadership role.
