The power we create together – when we combine your strengths with ours – is unstoppable. Are you ready to join a team that dreams as big as you do?

Role Summary

We are seeking an experienced Machine Learning Engineering Tech Lead to provide hands-on technical leadership for enterprise-scale Machine Learning, Generative AI and Agentic AI solutions. The role owns engineering quality across the full AI lifecycle—from data and feature engineering through model/LLM integration, deployment, MLOps, observability, security, scalability and production support. The ideal candidate combines deep ML engineering expertise with strong software engineering, cloud-native architecture and technical leadership capabilities.

Key Responsibilities

ML Engineering Leadership

• Lead and mentor ML Engineers and Data Scientists across multiple AI/ML initiatives.
• Define engineering standards, reusable frameworks, reference architectures and code-quality practices for ML solutions.
• Own technical design and code reviews, production-readiness reviews and complex problem resolution.
• Drive scalability, reliability, maintainability, security, performance and cost efficiency across AI products.

Machine Learning Architecture

• Design end-to-end ML architectures covering data, feature engineering, training, evaluation, registry, deployment, monitoring and retraining.
• Define batch and real-time inference patterns, model serving strategies, feature management, model versioning and rollback mechanisms.
• Establish reproducible experimentation, validation and model lifecycle standards.

Generative AI & LLM Engineering

• Lead enterprise GenAI solution design using LLMs, RAG, embeddings, vector databases, prompt engineering, structured outputs and tool/function calling.
• Design for context-window management, token optimization, semantic/prompt caching, model routing, hybrid search, reranking and grounded response generation.
• Implement LLM evaluation, hallucination mitigation, citations/grounding, guardrails and responsible AI controls.

Agentic AI Engineering

• Design multi-agent workflows, orchestration patterns, tool usage, memory strategies and human-in-the-loop controls.
• Implement retry/failure handling, secure agent-tool boundaries and observability for agent execution.
• Experience with LangGraph, LangChain, CrewAI, Semantic Kernel, AutoGen or similar frameworks is desirable.

RAG Architecture

• Design document ingestion, chunking, metadata, embeddings, vector retrieval, reranking and access-control-aware retrieval pipelines.
• Optimize RAG for retrieval accuracy, answer relevance, latency, cost, security and scalability.

MLOps & Model Lifecycle

• Establish automated training, experiment tracking, model registry, CI/CD, model validation, promotion, deployment, monitoring and retraining pipelines.
• Implement rollback, canary/blue-green deployment and model release governance.

Model Deployment & Cloud Engineering

• Deploy ML/GenAI workloads using Docker, Kubernetes/AKS, APIs, batch inference and event-driven architectures.
• Design autoscaling, GPU/CPU optimization, high availability, fault tolerance and graceful degradation.
• Prefer strong experience with Azure Machine Learning, Azure OpenAI, AKS, ACR, Databricks, Blob/ADLS, Service Bus, Key Vault and Azure Monitor.

Observability, Security & Cost Optimization

• Implement monitoring for model quality, drift, data quality, latency (P50/P95/P99), throughput, errors, GPU/CPU utilization, token consumption and cost.
• Optimize LLM and infrastructure cost using prompt optimization, caching, model routing, batching and autoscaling.
• Ensure PII protection, prompt-injection protection, secure tool execution, RBAC, audit logging, data-residency controls and enterprise security compliance.

Software Engineering Excellence

• Ensure ML products follow clean architecture, modular design, API-first development, automated testing, code review, static analysis and security scanning.
• Promote production-grade engineering beyond notebook-centric experimentation.

Required Technical Skills

• Strong programming skills in Python and SQL; experience with PyTorch, TensorFlow and/or scikit-learn.
• Strong knowledge of FastAPI/REST APIs, microservices, Docker and Kubernetes.
• Hands-on expertise in Machine Learning, Deep Learning, NLP, Generative AI, LLMs, RAG, embeddings, vector databases and prompt engineering.
• Practical knowledge of Agentic AI, LLM evaluation, AI guardrails and responsible AI.
• Good understanding of Spark, data pipelines, distributed processing, Delta Lake/data-lake patterns, feature engineering and data quality.
• Experience with MLflow, Azure ML, Databricks, Kubeflow and/or comparable MLOps platforms.
• Experience with GitHub Actions, Azure DevOps or equivalent CI/CD tooling.
