Job Summary We're looking for an Infrastructure Engineer to build developer tooling that enables developer velocity and reliability for the entire engineering organization. Our team owns the full end-to-end development lifecycle, from local development tools, CI/CD, dynamic testing environments, deployments, and releases. You’ll be working with the latest cloud-native technologies as you build an infrastructure platform that enables the engineering organization to deliver observability for some of the largest technology companies.

Architect & Build: Design and maintain high-scale developer tooling and backend services that improve productivity and reliability across a distributed cloud environment. We operate in a 100% modern, cloud-native ecosystem and you will work exclusively with ephemeral infrastructure and containerized microservices. Infrastructure as Code (IaC): Treat infrastructure as a first-class citizen. You will define, deploy, and manage entire environments using declarative IaC (Terraform), ensuring our platform is reproducible and version-controlled. Drive Systemic Quality: Identify and eliminate systemic bottlenecks in the software development lifecycle (SDLC) through architectural changes or advanced tooling. Scale & Reliability: Ensure our infrastructure remains resilient under massive traffic loads, optimizing for performance, cost-efficiency, and near real-time telemetry processing. Strategic Leadership & Mentorship: Define platform standards and reference architectures that span a 1–3 year horizon, balancing feature velocity with long-term technical debt. Act as the "glue" across teams, consulting on infrastructure best practices and up-leveling the organization through mentorship.

Required Qualifications 8+ years of relevant experience with the following: Foundational Technical Proficiency: Strong experience in at least one backend language (e.g., Go, Java, Python, or Rust). We value fluency and the ability to write modular, testable code over knowing a specific syntax. Strong proficiency in at least one backend language (e.g., Go, Java, Python, or Rust). We prioritize the ability to write modular, testable code over knowledge of a specific language syntax. Deep Systems Expertise: You go beyond "using" the cloud; you understand how it works. This includes: Cloud-Native: A solid understanding of cloud-native concepts and experience working with cloud providers like AWS or GCP. You should be comfortable navigating Kubernetes and container-level logic. Operating Systems & Compute: Deep knowledge of Linux internals, process management, and resource isolation. Networking & Security: Understanding of the OSI model,
