About the job

In this role, you will work at the intersection of applied research and engineering, designing and building production AI systems that combine large language models, traditional machine learning, and agent-based architectures. You will help translate cutting-edge AI concepts into real-world systems that power security detections and automated workflows at global scale.

Responsibilities

Design and build GenAI-powered agents that reason over signals, retrieve knowledge, and take intelligent actions to support complex workflows

Build AI systems with RAG, prompt engineering, and tool-using agents that handle multi-step workflows.

Build and integrate agent frameworks and AI services that enable reasoning, planning, and task execution

Apply traditional machine learning techniques (e.g., classification, anomaly detection, ranking) alongside LLM-based systems to improve overall system performance

Prototype and iterate on novel AI approaches, translating emerging research into practical production systems

Implement context engineering, structured outputs, and guardrails to improve system reliability and consistency

Develop and deploy production-grade AI systems, ensuring scalability, performance, and resilience

Design and execute evaluation frameworks to measure: Groundedness Relevance and correctness Model and system performance (precision, recall, etc.)

Continuously improve systems through offline experimentation and production monitoring

Prototype and deliver advanced capabilities such as: Multi-agent orchestration Stateful reasoning and memory Context-aware decision systems

Collaborate with partner teams and researchers to bring new AI capabilities into production

Incorporate safe and responsible AI practices, including mitigating hallucinations, misuse, and prompt injection risks

Qualifications

Minimum

Bachelor's Degree in Statistics, Econometrics, Computer Science, Electrical or Computer Engineering, or related field AND 2+ years related experience (e.g., statistics, predictive analytics, research) OR Master's Degree in Statistics, Econometrics, Computer Science, Electrical or Computer Engineering, or related field AND 1+ year(s) related experience (e.g., statistics, predictive analytics, research) OR Doctorate in Statistics, Econometrics, Computer Science, Electrical or Computer Engineering, or related field OR equivalent experience.

Other Requirements: Ability to meet Microsoft, customer and/or government security screening requirements are required for this role. These requirements include, but are not limited to the following specialized security screenings: Microsoft Cloud Background Check: This position will be required to pass the Microsoft background and Microsoft Cloud background check upon hire/transfer and every two years thereafter.
