Job Summary

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.

Key Responsibilities

• 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.

Qualifications

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, service meshes, load balancing, and "zero-trust" security architectures.

• Distributed Systems: Experience building and debugging systems that deal with CAP theorem trade-offs, eventual consistency, and distributed tracing.

• Reliable Execution: A track record of completing assigned tasks/tickets reliably and estimating work effectively within a sprint. You take ownership of features from local development through to basic testing and delivery.

• Analytical Debugging & Quality: The ability to debug your own code efficiently using logs and tests, while proactively identifying edge cases (like nulls or limits) during the design phase.

• Collaborative Spirit: Strong communication skills to keep teammates informed, raise blockers early, and contribute meaningfully to code reviews and design discussions.

• Continuous Learning: A proactive approach to learning new tools, processes, and libraries. You are open to feedback and use incidents or code reviews as opportunities to up-level your skills.

• AI-Native Development: You embrace the future of engineering. Experience or interest in using AI coding assistants (like Cursor or Claude) to improve productivity and automate boilerplate tasks.
