Science & Research Jobs in Redmond, WA (Now Hiring) — 512 open — Page 16

The MDASH team is advancing how organizations discover and resolve vulnerabilities in source code. MDASH uses a multi-agent, multi-model system to analyze code, validate whether potential vulnerabilities are real and reachable, and provide developers with concrete fixes and guidance for verifying that code is no longer vulnerable. We are seeking a Principal Security Research Manager to lead the team responsible for the security research and evaluation that advance MDASH's vulnerability discovery, validation, and remediation capabilities. This team shapes how MDASH finds vulnerabilities across programming languages, vulnerability classes, and codebase types; determines whether findings are valid and actionable; and improves the quality of generated fixes. The team owns the eval-driven development and hill-climbing loop: identifying representative evaluation targets, curating trusted ground truth, analyzing failures, and turning those insights into measurable improvements in vulnerability discovery, validation, and fix quality. The ideal candidate combines deep expertise in vulnerability research and application security with demonstrated success leading highly technical teams. You will set the research and measurement strategy, develop security researchers, and partner across research, engineering, applied science, and product teams to turn evidence into measurable improvements for customers.

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.

• Lead, mentor, and develop a team of security researchers responsible for MDASH vulnerability discovery, validation, fix generation, and quality measurement.
• Define the research and quality roadmap for expanding MDASH coverage across vulnerability classes, programming languages, frameworks, codebase sizes, and real-world development patterns.
• Establish measurable quality goals and decision criteria across recall, precision, consistency, vulnerability validation, fix correctness, and end-to-end resolution.
• Direct the creation and curation of representative evaluation suites and trusted ground truth drawn from purpose-built vulnerable code, public benchmarks, open-source projects, internal codebases, and production feedback, ensuring the portfolio reflects real-world customer scenarios and guides measurable improvement in MDASH.
• Lead systematic analysis of false negatives, false positives, inconsistent detections, validation failures, and ineffective or incorrect fixes; translate findings into prioritized improvements to the techniques, tools, agent behaviors, model configurations, and analysis methods that power MDASH.
• Partner with MDASH engine, evaluation infrastructure, model, applied science, and product teams to integrate research improvements, establish release gates, and connect offline measurements with customer outcomes.
• Communicate technical strategy, evaluation results, risks, and investment priorities to senior leaders and cross-functional partners.
• Model Microsoft values and foster an inclusive environment in which researchers can do their best work, grow their expertise, and take accountability for customer outcomes.
