As a Corporate Communication Senior Manager focused on Executive Communications Programs, you will build and scale Datadog's integrated thought leadership program — spanning executive communications, earned and owned channels, and events — with a focus on extending it across priority regions. This role sits at the intersection of strategy and execution: you'll translate leadership priorities into playbooks, frameworks, and measurable programs, then run them day to day. Success hinges on connecting dots across initiatives and partner teams to find new opportunities to tell Datadog's story through our executive voices. At Datadog, we place value in our office culture - the relationships and collaboration it builds and the creativity it brings to the table. We operate as a hybrid workplace to ensure our Datadogs can create a work-life harmony that best fits them. What You'll Do: Partner with the Global Head of Corporate Comms to develop and execute an integrated thought leadership program with clear objectives and measurable outcomes. Build the operating framework behind the program — playbooks, cross-team coordination models, and repeatable processes that let it scale across regions. Identify opportunities to put Datadog thought leaders in front of the right audiences, including vetting speaking engagements: where we need to be, what we should be saying, and which channel (social, traditional media, stage) delivers the most impact. Work with US Comms and Social leads to augment existing campaigns and build evergreen thought leadership programs across channels. Partner with Field Marketing on event strategy and execution, with a focus on advancing our key narratives around AI and security. Develop strategic messaging for senior executives across key business moments — corporate announcements, company milestones, and other high-priority communications. Serve as the Corporate Comms "captain": keep a bird's-eye view of initiatives across the company, manage day-to-day coo

NVIDIA DGX Cloud is an AI Factory designed to power the next generation of AI and industrial-scale breakthroughs. As a Principal Engineer for Security Architecture, within our Security Engineering organization, you will own a core security domain of the AI factory: the architecture, the paved road that delivers it, and much of the code underneath. You will hold the security design bar across DGX Cloud from inside the teams doing the building, and this is a founding seat on a new team. Security Engineering is a new organization at DGX Cloud, accountable for the security outcome of the platform, and Security Architecture is the function inside it that holds the design bar. Security here is fleet horizontal and stack vertical, so your work will cross every DGX Cloud engineering organization: you will embed with the teams building GPU clusters, control planes, and services, join their designs as a participant rather than an approver, and leave behind systems in which an entire class of risk is no longer possible. There is no architecture review board here and no approval queue. You are a senior IC with deep security domain knowledge, and the security bar holds because you helped set it and then helped ship it. What You Will Be Doing: Own a Security Domain End to End: Take architectural ownership of a core domain of DGX Cloud security, from the design through the system running in production. That could be tenant and GPU workload isolation, workload identity, infrastructure and network, supply-chain provenance, hardened baselines and patching, or deploy-time policy and admission control.
