• Build and configure Retrieval-Augmented Generation (RAG) pipelines.
• Design and establish the foundational frameworks and harnesses required to support AI development.
• Make technical decisions regarding AI architecture, implementation approaches, and tooling.
• Investigate and troubleshoot complex technical challenges independently.
• Establish technical foundations and best practices for ongoing AI development.
• Collaborate with engineering teams to integrate AI capabilities into existing or emerging solutions.
• Provide technical guidance, knowledge transfer, and upskilling to the internal team.
• Contribute to AI testing and validation approaches when aligned with the candidate's expertise.

Required Qualifications

• Strong hands-on experience designing and implementing AI-based solutions.

• 5+ years of professional software engineering experience using .NET or Java is a must.

• Demonstrated experience building AI pipelines and supporting infrastructure.

• Solid understanding of AI architectures and implementation practices.

• Experience designing and implementing foundational technical frameworks.

• Ability to evaluate technical approaches and explain architectural decisions.

• Strong troubleshooting and problem-solving capabilities.

• Experience working on projects where technical foundations needed to be established from scratch.

Preferred Qualifications

• Experience designing and implementing RAG pipelines.
• Experience establishing AI development frameworks or harnesses.
• Experience mentoring engineers and transferring technical knowledge.
• Familiarity with AI testing and validation methodologies.
• Previous involvement in Greenfield AI initiatives or early-stage technical environments.
