Senior Security Engineer


Location: Redmond, Washington

Job Type: Full time


Microsoft Azure is at the center of Microsoft’s cloud services strategy and the future of Microsoft. Azure brings together virtualization, compute, storage, authentication, authorization, artificial intelligence and machine learning, media and more to enable anyone to bring their business into the cloud. The Azure Development Security Engineering organization focuses on ensuring that Azure is the most secure platform in the world and delivers a secure experience for millions of users worldwide.

We seek a diligent, insightful, and creative Senior Security Engineer to help discover, diagnose, analyze, quantify, characterize, and drive solutions for the most challenging security problems in Azure through a data-driven, product-driven lens. In this role, you will advance security by working with other Security Engineers, Program and Product Managers, and Developers, as well as business leaders throughout Microsoft to turn individual findings and vulnerabilities into patterns and insights that can be measured and managed through engineering, automation, and other appropriate mitigations.  You will identify the most demanding security problems through original research and data analysis and help design and deliver practical solutions at scale for select products and services. This role is not confined to any area of technology; rather, you will work up and down the stack, across platforms, operating systems, languages, and frameworks, using your broad security skills to solve problems in unfamiliar domains.


Key responsibilities include:

  • Vulnerability discovery and variant hunting. Using the best available and most appropriate methodologies, including threat modeling, penetration testing, security design analysis, fuzzing, SAST and DAST, etc., you will examine chosen target systems in detail, looking for vulnerabilities and weaknesses, perform variant hunting looking for larger patterns, conduct qualitative and quantitative analysis over those patterns, and drive solutions upstream in a data-driven, shift-left fashion.
  • Solution design and delivery: You will help design solutions for security problems and partner with service teams and other security stakeholders to ensure rapid adoption of solutions and mitigation of threats from beginning to end.
  • Software development: You will develop proof-of-concept demonstrations, appropriate tooling, scanners, data management systems, and other small tools to better assist in both the discovery and remediation of security issues.
  • Follow through and closure. You will partner with engineers, product and program managers, and leaders around the company to ensure the successful completion of work to address your findings

To thrive in this position, you will need a detailed technical understanding of a broad set of technologies and the ability to learn new information at a rapid pace. We do not expect that any individual knows all the technologies that are in scope for this role, rather we are looking for someone who can quickly translate their technical skills from one domain to another, find, assemble, and inspire the relevant technical experts from across the company, and communicate effectively about technical and business risks to engineering and executive leadership.


Required Qualifications:

  • 8+ years experience in security and/or software engineering
  • Expert level knowledge regarding multiple classes of vulnerabilities, including cross-site scripting, buffer overflows, SQL injection, TOCTOU (Time of Check Time Of Use) vulnerabilities, cryptographic weaknesses, insecure direct object references, and others, and the ability to communicate about them to technical and non-technical audiences
  • Bachelors degree in Computer Science, Mathematics, Engineering degree or equivalent experience

Preferred Qualifications:

  • Strong leadership, empathy, and interpersonal skills
  • Strong written and verbal communication skills
  • MS or PhD in Computer Science, Mathematics, Engineering, or related fields




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: Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud background check upon hire/transfer and every two years thereafter.
