• Establish best practices for prompt engineering, model selection, fine-tuning, and guardrails across the organization.
• Design and operate production infrastructure for AI systems, including monitoring, observability, cost management, and failure recovery.
• Provide technical leadership across multiple teams, aligning AI engineering efforts with product and business strategy.
• Evaluate and introduce new AI technologies, frameworks, and patterns to improve system capability and developer velocity.
• Mentor and coach senior engineers, raising the organization’s overall AI engineering maturity.
• Lead design reviews, architecture reviews, and post-incident analyses for AI systems.
• Partner closely with Product, Design, Data Science, and Infrastructure leadership to shape the AI roadmap and technical investment priorities.
• Represent the engineering organization in cross-functional and executive-level discussions on AI strategy.

Do you have experience in Scalable systems?, * 10+ years of professional software engineering experience with significant recent focus on AI systems, and at least 3 years operating at a staff or principal level.

• Proven track record of driving complex AI systems from concept to production at scale.
• Hands-on experience building production systems using AI orchestration frameworks such as Semantic Kernel, LangGraph, LangChain, or equivalent.
• Deep understanding of AI evaluation methodologies - including offline benchmarks, online monitoring, A/B testing, and human evaluation - and experience building eval pipelines.

• Familiarity with modern cloud platforms (AWS, GCP, or Azure) and container orchestration (Kubernetes, Docker).
• Background in CI/CD, observability, and reliability engineering practices tailored to AI workloads.
• Demonstrated ability to deliver AI-first solutions using AI-assisted development tools such as Claude Code, Cursor, or equivalent.
• Experience with model lifecycle management: selection, fine-tuning, versioning, deployment, and cost optimization.
• Experience with vector databases, embedding models, and semantic search systems.
• Knowledge of responsible AI practices including bias detection, safety testing, and content filtering.
• Contributions to open-source AI projects or published technical writing on AI engineering topics.
