Our GTM Enablement team plays a critical role in helping Datadog’s Sales and Customer Success teams succeed by equipping them with the right skills, knowledge, and tools at the right time. We partner closely with teams across Sales, Customer Success, Product Marketing, Strategy & Operations and more to ensure enablement programs translate into real performance in the field. The Program Management team within Sales Enablement is a group of interdisciplinary thinkers leveraging diverse business backgrounds in engineering, education, management consulting, business operations (and more!) to define, manage and measure Datadog’s global go to market motion. We solve complex, systemic challenges that impact go-to-market effectiveness by diagnosing root causes, whether behavioral, skills-based, or structural, and shaping the strategic solutions that resolve them.

As a Senior Program Manager on the Sales Enablement Program Management team, you will design, plan, and execute complex, global, cross-functional programs that change how our Go-to-Market (GTM) teams operate at a systems level. You will own the end-to-end enablement process for the programs and stakeholder relationships you’re responsible for: diagnosing the gap, gathering field evidence, building a multi-faceted strategy (not just a content solution), partnering across teams to deliver the experience, and reporting business impact to Sales and Customer Success leadership. This is a high-ownership role for someone who moves quickly, thinks strategically and creatively, and is equally comfortable analyzing hard data and reading what’s happening on the ground. You’ll drive adoption at scale with limited guidance, influence senior stakeholders without positional authority, and help shape how the Program Management function o

Datadog is entering a new chapter in how our product looks, feels, and operates. Our Design Lab is defining a new visual direction for the platform, and we’re looking for a Senior Staff Visual Product Designer to help turn that direction into a coherent product experience. Datadog is dense, technical, and used by people working through complex problems—often under real pressure. The challenge is not simply applying a new aesthetic. It is rethinking hierarchy, layout, navigation, interaction, and product patterns so the experience becomes clearer, more cohesive, and more expressive without losing the power our users rely on. This is a hands-on product design leadership role for someone who combines strong visual judgment with deep product and systems thinking. You’ll work alongside visual designers, motion designers, product designers, Design Systems, and Engineering to ensure the new direction changes how Datadog works—not just how it looks. What You'll Do Co-develop Datadog’s next visual direction by applying and stress-testing it across representative product journeys. Translate visual principles into concrete decisions about hierarchy, layout, navigation, information architecture, interaction, and behavior. Use visual language to clarify complex, data-dense experiences — hierarchy, density, and attention. Hold the visual quality bar across work you don't own, and align teams around it. Prototype, test, and refine new patterns before they become systemized. Partner deeply with Product Design, Design Systems, and engineering to turn successful concepts into durable system guidance and implementation. Create clear artifacts, pilots, and narratives that help teams adopt the direction and raise the product quality bar. Influence stakeholders across design, engineering, product, and executive partners. You will report directly to the Design Director and work as part of a small, focused team defining the future state before it scales across hundreds
