Accountabilities:

• Define and drive the overall technical architecture for both the established enterprise search platform and the emerging AI/RAG product line.
• Lead critical decisions on scalability, infrastructure design, system reliability, and long term technical evolution.
• Own deployment strategies, operational readiness, and infrastructure stability across all engineering initiatives.
• Guide the evaluation and adoption of modern engineering tools, with a strong focus on AI assisted development practices.
• Lead, mentor, and support a team of experienced engineers, fostering autonomy, technical excellence, and continuous improvement.
• Conduct architectural and code reviews while providing high quality technical guidance and feedback.
• Collaborate closely with executive leadership on product strategy, roadmap prioritization, and business alignment.
• Manage enterprise level technical requirements, including security reviews, compliance standards, and customer SLAs.
• Lead SOC 2 compliance efforts and support audit and security certification processes.
• Balance technical debt, feature delivery, and system reliability across competing priorities.
• Stay actively involved in architecture and system design, maintaining strong technical credibility within the team.
• Champion AI/ML innovation, especially in RAG systems, LLM applications, and modern development workflows.

Requirements:

• 10+ years of software engineering experience, including significant leadership responsibilities in senior technical roles.
