Original job description

Overview

Security represents the most critical priorities for our customers in a world awash in digital threats, regulatory scrutiny, and estate complexity. Microsoft Security aspires to make the world a safer place for all. We want to reshape security and empower every user, customer, and developer with a security cloud that protects them with end to end, simplified solutions. The Microsoft Security organization accelerates Microsoft’s mission and bold ambitions to ensure that our company and industry is securing digital technology platforms, devices, and clouds in our customers’ heterogeneous environments, as well as ensuring the security of our own internal estate.

The MDASH team is reimagining how organizations identify and remediate vulnerabilities in source code. Using AI agents and models, MDASH analyzes code to determine whether potential vulnerabilities are real and reachable, provides developers with actionable fixes, and helps verify that vulnerabilities have been successfully addressed.

We’re looking for a Principal Software Engineer to help build and evolve the MDASH scanning engine as we work to advance agentic code scanning. In this role, you’ll design and build systems that coordinate AI agents and models to analyze complex codebases, scale across programming languages and frameworks, validate security findings, generate high-quality fixes, and deliver reliable, efficient performance in production environments.

You’ll work closely with security researchers, applied scientists, model teams, and product managers to turn new techniques and evaluation insights into product capabilities. We’re looking for an engineer with experience building complex, large-scale systems, foundational knowledge of application security, and excitement about using AI to solve challenging problems in software security.

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

Responsibilities

Design, build, and evolve the MDASH scanning engine, including agent orchestration, multi-model routing, code understanding, vulnerability detection, reachability validation, and fix generation and verification.
Extend the engine's coverage across vulnerability classes, programming languages, frameworks, build systems, and codebase sizes, from single services to large monorepos.
Integrate program analysis techniques into agent workflows to make detections more precise and grounded. These include static and dynamic analysis, taint tracking, call-graph and data-flow analysis, fuzzing, and sandboxed execution.
Improve the engine's precision, recall, consistency, and fix quality, working from evaluation results, research findings, and production feedback.
Optimize scan performance, scalability, cost, and latency so MDASH works well on enterprise-scale codebases and in CI/CD workflows.
Build a secure, reliable, observable engine, with strong isolation for running untrusted code and clear telemetry for diagnosing agent behavior.
Work with security research, applied science, model, and product teams to bring new techniques and models into the engine quickly and safely.
Track the agentic security and code-scanning landscape, and bring forward ideas that make MDASH stand out against competitors.
Write high-quality, well-tested code. Lead design reviews, take part in code reviews and on-call rotations, and help raise the engineering bar for the team. Mentor other engineers and model Microsoft values to help build an inclusive environment where everyone can do their best work.

Qualifications

Required Qualifications:

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#, Java, JavaScript, TypeScript, or Python
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:

Preferred Qualifications:

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#, Java, JavaScript, TypeScript, 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#, Java, JavaScript, TypeScript, or Python
OR equivalent experience.
Experience building production systems with large language models, such as AI agents, multi-agent orchestration, tool calling, planning, context management, or code-understanding systems.
Experience building or working on security scanners, static analysis (SAST), dynamic analysis (DAST), software composition analysis (SCA), compilers, or other program analysis tools.
Working knowledge of vulnerability classes such as memory safety, injection, authentication and authorization, deserialization, path traversal, SSRF, and business-logic flaws.
Experience with program analysis techniques such as taint analysis, data-flow and control-flow analysis, code property graphs, fuzzing, or symbolic execution.
Experience building distributed, high-scale cloud services on Azure, including containerized or sandboxed execution.
Familiarity with multiple software ecosystems and build systems across C/C++, C#, Java, JavaScript/TypeScript, Python, and cloud-native applications.
A passion for developer experience, and for building tools that engineers trust and act on.
