Top SchoolDavid Mccourt is a Technical Lead in Infrastructure Security with 13 years of experience building dependable, extensible backend systems that balance elegance with operational rigor. Currently leading infrastructure security efforts at HubSpot, he designs and owns full software lifecycles for internal services that identify, manage, and remediate platform vulnerabilities. His toolkit spans Java, Python, Ruby, Docker, Kubernetes, AWS, and tooling around CI/CD, monitoring, and orchestration, with a strong emphasis on testability, observability, and runbooks. Past roles across transit, energy markets, and consulting show a consistent pattern of modernizing legacy systems and integrating complex operational workflows into cloud-native platforms. He blends hands-on engineering with stakeholder-facing analysis, often acting as DRI to drive projects from architecture through rollout and support. Outside enterprise security work, he has a history of pragmatic open-source-oriented engineering (notably Rails-based transit tooling) and mentoring teams to deliver reliable production services.
