• Lead technical spikes and convert prototypes into secure, production-ready implementations
• Establish observability, alerting, cost efficiency, and performance standards for AI services operating at enterprise scale
• Mentor engineers through Sprint execution, conduct design and code reviews, and elevate overall engineering quality
• Evaluate emerging AI frameworks (e.g., MCP, orchestration patterns) and introduce practical innovations aligned to product roadmap needs

Minimum Qualifications

• Bachelor's Degree plus at least 10 years of distributed systems or enterprise platforms experience, including 3+ years deploying AI/LLM systems into production environments, or demonstrated equivalent experience and education
• Proven hands-on experience designing and implementing RAG architectures in enterprise environments
• Deep expertise with Azure cloud services and cloud-native application design
• Strong foundation in APIs, distributed systems, security controls, and production observability
• Comfortable operating hands-on while leading technical direction

Preferred Qualifications

• Experience building or scaling enterprise chatbots or AI-driven internal platforms
