You'll build the internal platform that enables product teams to ship software faster, safer, and with greater confidence. Rather than simply managing infrastructure, you'll create self-service capabilities, intelligent automation, and reusable platform services that eliminate operational complexity and allow engineers to focus on building products. You will partner closely with software engineers to understand friction in the development lifecycle and turn those pain points into scalable platform capabilities. You'll work on problems like: Build self-service developer platforms that enable engineers to provision infrastructure, deploy applications, manage secrets, and access shared services with minimal operational overhead. Create reusable platform services and SDKs including identity & authorization, secrets management, deployment orchestration, service discovery, configuration management, and platform APIs. Design opinionated "golden paths" that make the easiest way also the best way for engineers to build, test, deploy, and operate software. Build intelligent CI/CD platforms that reduce deployment time, improve release confidence, and automate testing, security, and compliance. Improve developer workflows by investing in local development environments, faster build systems, ephemeral environments, and platform automation. Continuously measure and improve developer productivity through platform metrics, engineering insights, and workflow optimization. Collaborate with application teams to simplify software delivery, improve reliability, and remove operational toil through automation. Build platform capabilities that improve scalability, resiliency, observability, and operational excellence across the engineering organization. Champion Infrastructure as Code, GitOps, and platform engineering best practices while helping teams adopt modern engineering workflows. Experiment with emerging technologies, AI-assisted development, and developer tooling that transforms how engineers build software. The Team We believe great engineering organizations are built on great developer experiences. Our Platform Engineering team builds the internal products, services, and automation that every engineer depends on every day. We treat our platform as a product, with engineers as our customers and developer productivity as our north star. Our mission is to remove friction from software delivery by creating intuitive, self-service platforms that make infrastructure invisible, deployments effortless, and operational excellence the default. You'll work across every engineering team to understand their challenges, identify opportunities for automation, and build platform capabilities that scale with the organization. Whether it's reducing deployment time from hours to minutes, enabling one-click environment creation, or building reusable platform APIs, your work will have an immediate impact on every engineer at the company. If you're passionate about building tools that thousands of engineering workflows depend on—and enjoy solving complex distributed systems problems while improving the daily lives of other engineers—you'll thrive here. What We're Looking For We're looking for engineers who enjoy building platforms rather than operating infrastructure.
