Microsoft Security aims to make the world a safer place by reshaping security and empowering every user, customer, and developer with a security cloud that protects them with end-to-end, simplified solutions.

Requirements

  • 6+ years of experience driving complex, cross-functional initiatives; experience leading without authority across multiple teams.
  • 3+ years working with Machine Learning (ML)/Artificial Intelligence (AI) systems (e.g., Large Language Models (LLMs)/Generative AI (GenAI), retrieval/Retrieval-Augmented Generation (RAG), model serving, experimentation platforms, data pipelines) including establishing evaluation metrics and improving model quality.
  • Hands-on coding ability in one or more languages (e.g., Python, C-Sharp, C++, Rust, JavaScript/TypeScript); comfortable prototyping, reading Pull Requests (PRs), and engaging deeply in technical design reviews.
  • Experience with GenAI/LLM techniques and tooling (prompt engineering, retrieval/vector stores, agents/tool use, content safety/guardrails, offline/online eval frameworks, vibe coding).
  • Security domain expertise (e.g., threat detection/response, SIEM/SOAR, identity, endpoint, cloud security) and familiarity with analyst workflows.
  • Proven track record shipping cloud services or platforms at scale (multi-tenant, high-throughput) with measurable customer and business impact.
  • Demonstrated success driving zero-to-one (0 1) initiatives from ambiguity to Minimum Viable Product (MVP) to General Availability (GA) and then to one-to-many (1 N) platform adoption across multiple product teams.

Responsibilities

  • Define the vision, strategy, and roadmap for AI-native incubation initiatives; align stakeholders across Security Copilot, Defender, Sentinel, Entra, Purview, Azure AI Foundry and Microsoft AI to deliver cohesive customer value.
  • Lead zero-to-one (0 1) incubation R&D through MVP and private preview, then drive one-to-many (1 N) platformization and scale to GA; make principled tradeoffs across quality, latency, reliability, cost, and safety.
  • Provide hands-on technical leadership: prototype in code, review designs and Pull Requests (PRs), define Application Programming Interfaces (APIs)/data contracts, build comprehensive well-architected systems, and establish evaluation frameworks to de-risk complex systems.
  • Set strategy for AI-native security experiences and platform components: where to use Large Language Models (LLMs) versus classical Machine Learning (ML), retrieval/Retrieval-Augmented Generation (RAG) design, grounding, model routing/fallbacks, and safety guardrails to meet customer outcomes and Service Level Objectives (SLOs).
  • Ensure Responsible AI, privacy, and security guardrails are designed in from day one, coordinate safety reviews, abuse prevention, compliance, and incident readiness.
  • Lead v-teams and mentor others; cultivate a builder culture of velocity and quality as a force multiplier.
  • Engage directly with enterprise customers and field to co-design solutions and land adoption; communicate program status and strategy to executives with hands on real code demonstrations.

Other

  • Bachelor's Degree in Computer Science or related technical field AND 6+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C-Sharp, Java, JavaScript, or Python OR equivalent experience.
  • Ability to meet Microsoft, customer and/or government security screening requirements are required for this role.
  • Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud background check upon hire/transfer and every two years thereafter.
  • Master's Degree in Computer Science or related technical field AND 8+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C-Sharp, Java, JavaScript, or Python OR Bachelor's Degree in Computer Science or related technical field AND 12+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C-Sharp, Java, JavaScript, or Python OR equivalent experience.
  • Experienced in program leadership, communication, and stakeholder management skills with the ability to influence leaders and make data-informed decisions.
