A career at Roblox means you’ll be working to shape the future of human interaction, solving unique technical challenges at scale, and helping to create safer, more civil shared experiences for everyone. As a Senior Software Engineer on the Orchestration pod within Engine Productivity, you'll design and run the platform that executes large-scale end-to-end and integration tests, running the real, shipping client on real hardware, across Roblox's data centers, cloud, and our own device labs, so our engineering teams can ship the engine, clients, Studio, and more with speed and confidence. Every Roblox engine, client, and Studio change, along with the experiences built on top of them, should ship with confidence, and the Orchestration team is the layer that makes that possible. We build large-scale distributed services that turn thousands of test suites into a reliable, push-button pipeline: fanning work out across fleets of machines and real devices, moving artifacts to where they're needed, managing single- and multi-client test state, and giving test owners and maintainers a system to validate their own runs. It looks a lot like building a specialized cloud platform, with capacity-aware scheduling, isolation and sandboxing, and smart retry and backoff, plus the classic distributed systems problems (fairness, efficiency, failure handling, and reliability) at Roblox scale.

Datadog’s Technical Solutions organization includes 1,200+ sales engineers, support engineers, post-sales experts, and solution architects. They run on an ecosystem of enterprise platforms and internal tools that directly shape how we serve customers. Technical Solutions Operations (“TSO”) owns that ecosystem. We manage the full lifecycle of the systems TS depends on: Zendesk, Jira, Confluence, and a growing portfolio of off-the-shelf and purpose-built tools. We do the work to operate, maintain, and evolve the platforms powering daily workflows across TS. When a vendor tool reaches its limits, we extend it through customization, integration, or targeted solution development, tapping internal partners across Datadog as needed. We’re looking for a Systems Engineer who wants to own enterprise platforms end-to-end. You go from understanding the business process, to designing the right solution (whether that’s configuration, integration, or code), to measuring whether it actually moved the needle. 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: Own enterprise systems through their full lifecycle. You’ll be the technical owner for one or more platforms that TS relies on daily. That means understanding how the system is used, where it’s falling short, what’s coming from the vendor roadmap, and what needs to change. You drive improvements from assessment through implementation. Engineer solutions that create leverage. Not every problem is solved by configuration. You’ll build and evolve enterprise systems, integrations, automations, and internal tools that multiply the effectiveness of 1,200+ technical experts. Where AI can make a solution smarter (e.g., intelligent routing, automated triage, agent-assisted workflows), you'll include AI in the initial design, no
