Consultancy Nature of Work:

As a Keystone Solutions consultant, you will operate within a client-facing environment, embedding with product, platform, and security teams at our client to deliver tangible outcomes.

Dynamic Projects:

Expect variety. Across client engagements, you may tune SonarQube quality profiles, elevate secure coding practices, align findings to the OWASP Top 10, optimize SAST integration in CI/CD, and coach teams through code review improvements—adapting your impact to each clients context.
