🎯 The Role

We’re looking for a Senior Platform Engineer, Infrastructure to build and own the foundational cloud and source control infrastructure that sits outside our product. This role is distinct from our Product Infrastructure and Developer Productivity teams: rather than supporting product systems or professional engineering workflows, you'll stand up the corporate cloud foundation from the ground up — multi-account architecture, networking, DNS, PKI, and secrets management — along with the GitHub-based delivery pipelines that govern how infrastructure gets provisioned and changed.

You'll design the landing zone and the paved-road templates that make hosting and source control self-service by default. Builders on this platform range from engineers to AI-assisted teams across the business, so the guardrails you build — policy-as-code, scoped modules, tagging enforcement, cost controls, security baselines — carry the weight a human reviewer otherwise would. Making that system permissive enough to be useful and constrained enough to be safe is the central challenge of the role.

✅ Key Responsibilities

• Design and maintain foundational shared services — VPCs, DNS, PKI, and secrets management — that other teams and self-service pathways depend on
• Own the cloud landing zone and paved-road templates that make hosting and source control self-service by default
• Build policy-as-code, scoped modules, tagging enforcement, cost controls, and security baselines to create a system that is both useful and safe
• Design and maintain GitHub-based delivery pipelines that govern how infrastructure gets provisioned and changed
• Stand up the corporate cloud foundation from the ground up, including multi-account architecture, networking, DNS, PKI, and secrets management

📌 Required Qualifications

• Experience with cloud infrastructure, including multi-account architecture, networking, DNS, PKI, and secrets management
• Experience with GitHub-based delivery pipelines and infrastructure as code
• Strong understanding of policy-as-code, scoped modules, tagging enforcement, cost controls, and security baselines
• Experience with designing and maintaining foundational shared services, including VPCs, DNS, PKI, and secrets management
• Experience with building self-service platforms for engineers and AI-assisted teams

⭐ Desirable Experience

• Experience with AWS or other cloud platforms
• Experience with Terraform or other infrastructure as code tools
• Experience with Kubernetes or other container orchestration platforms
• Experience with CI/CD pipelines and automation
