Webflow is the agentic web marketing platform for modern marketing teams, helping organizations build, manage, and optimize high-performing web experiences that drive predictable growth and strengthen brand trust. Building at Webflow will need grit, because we move fast, without ever sacrificing craft or quality.

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.

As a Senior Platform Engineer, Infrastructure, you'll...

• 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: multi-region connectivity, account/resource structure, tagging standards, and cost-efficient scaling
• Build and maintain Infrastructure as Code pipelines (Terraform, Pulumi, or Ansible) so infrastructure changes are automated, tested, and repeatable
• Design self-service pathways for code hosting (templated repo creation with standards baked in — visibility, branch protection, CI hooks) so builders can get set up without platform team involvement
• Design self-service deployment pathways — a small set of golden-path hosting patterns (e.g., static sites, lightweight services, scheduled jobs) that provision automatically into the governed landing zone
• Build the guardrails that make self-service safe: poli
