The Microsoft Security organization accelerates Microsofts 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.
Were looking for a Senior Software Engineer to help build and evolve the MDASH scanning engine as we work to advance agentic code this role youll 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.
Youll work closely with security researchers applied scientists model teams and product managers to turn new techniques and evaluation insights into product capabilities. Were 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.
Microsofts mission is to empower every person and every organization on the planet to achieve more.

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 engines 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 engines 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.
