About The Position

Microsoft Security is building AI-powered capabilities to help defenders detect, investigate, and respond to threats while keeping people in control of critical decisions. Within the Agentic Security Organization, Data Platform & Graph and Agent Runtime & Orchestration in Perception Platform provide the data foundations and runtime for AI agents to triage alerts, conduct investigations, and take governed action. Agents use secure identities and boundaries, coordinate and hand off work, recover from failures, and make their actions and reasoning visible to customers. This shared opportunity spans teams led by David Weston and Pankaj Naik. Depending on the team, the role focuses on large-scale security data and graph capabilities or platforms and workflows that enable security agents to reason, collaborate, and take governed action. The specific team and scope will be matched to the candidate’s experience and interests. The engineer will build and operate production software, address distributed-systems challenges, improve reliability and performance, and collaborate across engineering, product, and security research to deliver useful outcomes for defenders. At the Software Engineer II level, the role builds and improves secure, scalable services and supports production operations and customer-driven improvements. At the Senior Software Engineer level, the role leads the architecture, delivery, and operation of significant components, owns live-site health and incident response, and mentors other engineers. The position requires passing Microsoft’s Cloud Background Check upon hire or transfer and every two years thereafter.

Requirements

Bachelor’s degree in Computer Science or a related technical discipline and 2+ years of technical engineering experience coding in languages such as C, C++, C#, Java, JavaScript, or Python, or equivalent experience.
Ability to meet Microsoft, customer, and/or government security screening requirements, including passing the Microsoft Cloud Background Check upon hire or transfer and every two years thereafter.

Nice To Haves

4+ years of programming experience in Java, C++, C, or another object-oriented language, with an understanding of data structures, algorithms, and distributed systems.
4+ years of experience building and shipping production software or services, including online services or fault-tolerant distributed systems.
4+ years of experience writing secure, maintainable, well-tested, and performant code; using debugging tools and code reviews to improve quality; and applying modern development practices such as agile methods, test-driven development, or AI-assisted development.
4+ years of experience translating customer needs into technical solutions, collaborating across teams, and improving service quality through testing, deployment automation, and security practices.
Experience taking a new product from initial development to launch.
Experience leading design discussions, defining test strategies, and driving improvements across components or projects.

Responsibilities

Build and improve secure, scalable services for security data platforms, pipelines, graph-based workloads, or agent-runtime capabilities, depending on the team.
Develop and support batch or streaming ingestion and processing components, focusing on data quality, observability, recovery, and cost.
Write well-tested, maintainable code and use telemetry and production signals to improve service performance, reliability, and security.
Partner with product managers, designers, and engineers to understand customer needs, deliver features, and raise technical risks or blockers early.
Support live-site operations and use customer feedback to guide improvements, including improvements to security and privacy.
Lead the design and delivery of significant data-platform, distributed data-service, or agent-runtime components from architecture through production operation.
Build and operate reliable batch or streaming pipelines and services for security investigations, analytics, or graph-based workloads; make architectural trade-offs across data quality, performance, reliability, and cost.
Improve production service scalability, security, observability, recovery, and operating cost using telemetry, quality metrics, and customer feedback.
Own live-site health and incident response for assigned components.
Partner across teams to resolve dependencies and mentor engineers through design and code reviews.
Work with product, design, engineering, and customers to shape capabilities and advocate for customer security and privacy needs.
