Senior ML Engineer

Job Overview

As a Senior AI Engineer, you'll be a contributor across our Search and AI engineering teams, shaping the architecture of systems that bridge traditional backend engineering with cutting-edge AI capabilities. You'll work across the full stack — from cloud infrastructure and distributed systems to agent orchestration and AI evaluation frameworks — built on .NET, python and Azure at enterprise scale.

Job Description and Requirements

Responsibilities 

• Design, develop, and operate secure, maintainable, and scalable AI systems using object-oriented principles, modern architecture, and cloud-native patterns. 

• Build and deploy intelligent AI agents capable of autonomous reasoning, decision-making, and task execution across enterprise systems. 

• Integrate AI orchestration and reasoning frameworks (e.g., LangChain, Semantic Kernel, MLflow, vector databases) into production environments to deliver real business value. 

• Develop retrieval, orchestration, and reasoning pipelines for AI agents, enabling context-aware and multi-turn interactions with enterprise data sources and APIs. 

• Utilize Azure AI and cloud services (Azure ML, Cognitive Services, Functions, App Services, Cosmos DB, Azure DevOps) to create scalable AI-enabled applications. 

• Collaborate with cross-functional teams including product, backend, and data engineering to design interfaces and protocols for AI-agent collaboration. 

• Drive engineering excellence through code reviews, architecture discussions, and mentorship. 

• Champion DevOps and MLOps best practices—CI/CD pipelines for AI workflows, observability for inference performance, and reproducibility of agentic systems. 

• Adopt AI-assisted development tools (e.g., GitHub Copilot, Cursor, OpenAI API tooling) to accelerate software delivery and improve developer productivity. 

• Ensure reliability and observability of deployed AI systems using monitoring, logging, and runtime performance metrics. 

• Contribute to architectural decisions around agent frameworks, model lifecycle management, and cloud-native scalability. 

• Stay current with emerging AI technologies and frameworks, sharing insights and recommendations that shape the company’s AI strategy. 

Minimum Qualifications 

• Bachelor’s degree in Computer Science, Artificial Intelligence, or a related technical field—or equivalent practical experience. 

• 5+ years of experience in software engineering or machine learning engineering, including designing distributed systems. 

• Proficiency in Python and at least one other general-purpose language (C#, Java, or Go). 

• Experience with AI engineering and orchestration frameworks such as LangChain, Semantic Kernel, MLflow, or similar. 

• Familiarity with cloud platforms (Azure, AWS, or GCP) and containerization technologies (Docker, Kubernetes). 

• Strong understanding of modern software architecture, API design, and secure cloud development. 

• Demonstrated ability to collaborate effectively and communicate complex technical concepts clearly. 

Preferred Qualifications 

• Experience building autonomous or semi-autonomous agents using frameworks such as LangChain, Semantic Kernel, or custom orchestration layers. 

• Background in retrieval-augmented generation (RAG), knowledge graphs, or contextual search. 

• Experience designing or maintaining MLOps pipelines, including model tracking, evaluation, deployment, and monitoring. 

• Knowledge of data engineering and event-driven systems (Kafka, Spark, DataBricks). 

• Familiarity with AI safety, evaluation, or prompt engineering concepts. 

• Solid background in mathematics, statistics, and data analysis, especially in probability, linear algebra, and optimization. 

• Prior experience mentoring junior engineers and contributing to AI product roadmaps.
