What You’ll Do
As a Lead AI Engineer at InteractiveAI, you’ll operate as the Chief of AI’s right hand, driving the technical direction of our AI stack, accelerating new use cases, and guiding the development of advanced GenAI capabilities across the platform.
You’ll take ownership of the design, development, and deployment of cutting-edge models, agentic architectures, and fine-tuning workflows. You will lead experimentation efforts, influence architecture decisions, mentor engineers, and ensure our AI systems are scalable, reliable, and aligned with enterprise requirements.
You’ll work in a cross-functional squad while also contributing to org-wide AI standards, frameworks, and best practices.
- Build and maintain scalable pipelines for structured/unstructured data ingestion, transformation, and feature engineering
- Lead the deployment of ML models and LLMs into production, ensuring performance, reliability, and traceability
- Architect and oversee fine-tuning pipelines for LLMs with versioned checkpoints, evaluation suites, and experiment tracking




- Design and implement automated evaluation frameworks (A/B testing, LLM-as-judge, validation suites) and monitoring dashboards to track latency, accuracy, drift, and trigger retraining or alerts
- Guide feature engineering, imputation, and transformation strategies in complex, real-world scenarios
- Implement and optimize retrieval-augmented generation (RAG) workflows, vector search approaches, and knowledge-grounding strategies
- Lead the development of enterprise-grade agentic workflows, tooling integrations, and agent evaluation methods
- Optimize inference speed, memory usage, and cost for high-throughput systems across the platform
- Own reliability and performance of models in production, solving challenges around latency, accuracy, drift, and scaling
- Collaborate with product and delivery teams to ship client-ready, measurable outcomes and accelerate new AI-driven features
