Webflow is seeking a Senior Platform Engineer, Infrastructure to design and own the foundational cloud and source control infrastructure that serves the entire organization. This role is distinct from product infrastructure teams—you'll build the corporate cloud foundation from the ground up, including multi-account architecture, networking, DNS, PKI, secrets management, and GitHub-based delivery pipelines that govern how infrastructure gets provisioned and changed.
You'll design the landing zone and paved-road templates that make hosting and source control self-service by default. Your guardrails—policy-as-code, scoped modules, tagging enforcement, cost controls, security baselines—will carry the weight a human reviewer otherwise would. The central challenge is making the system permissive enough to be useful and constrained enough to be safe.
Key responsibilities include:
- Design and maintain foundational shared services (VPCs, DNS, PKI, secrets management) that other teams depend on
- Own the cloud landing zone: multi-region connectivity, account/resource structure, tagging standards, and cost-efficient scaling
- Build and maintain Infrastructure as Code pipelines (Terraform, Pulumi, Ansible) for automated, tested, repeatable infrastructure changes
- Design self-service pathways for code hosting with standards baked in (visibility, branch protection, CI hooks)
- Design self-service deployment pathways with golden-path hosting patterns that provision automatically into the governed landing zone
- Build guardrails for safe self-service: policy-as-code, tagging enforcement, cost controls, security baselines
- Develop foundational observability infrastructure (logging, metrics, tracing) for system health visibility
- Partner with SRE on platform reliability: availability, resilience, performance
- Manage cloud vendor and tooling relationships, flagging risk and cost issues early
Requirements: 5+ years in platform, infrastructure, or cloud engineering with demonstrated ownership of production cloud environments. Hands-on experience with a major cloud provider (AWS, Azure, GCP) including multi-account architecture. Strong Infrastructure as Code experience (Terraform, Pulumi, Ansible). Experience with GitOps-style delivery pipelines (GitHub Actions or similar). Solid grounding in networking and security fundamentals (VPC design, DNS, PKI, secrets management). Experience with observability tooling (Datadog, Prometheus, Grafana). Familiarity with cloud cost management (FinOps) practices. Strong cross-functional collaboration skills with SREs, security, and developer productivity teams.
