Senior Platform Engineer, Infrastructure
About The Position
Webflow is seeking a Senior Platform Engineer, Infrastructure to build and own the foundational cloud and source control infrastructure that sits outside of their product. This role is distinct from Product Infrastructure and Developer Productivity teams. The engineer will establish the corporate cloud foundation from the ground up, including multi-account architecture, networking, DNS, PKI, and secrets management, as well as GitHub-based delivery pipelines for infrastructure provisioning and changes. The role involves designing a landing zone and self-service templates for hosting and source control, with guardrails such as policy-as-code, scoped modules, tagging enforcement, cost controls, and security baselines to ensure safety and usability for a diverse range of builders, including engineers and AI-assisted teams.
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, or GCP), including multi-account architecture
- Strong Infrastructure as Code experience (Terraform, Pulumi, or 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 (e.g., Datadog, Prometheus, Grafana)
- Familiarity with cloud cost management (FinOps) practices
- Strong cross-functional collaboration and partnership skills with SREs, security, and developer productivity
Nice To Haves
- Experience supporting non-engineering builders (e.g., citizen developers, AI-assisted tooling users) with infrastructure they can self-serve
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: 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: policy-as-code, tagging enforcement, cost controls, and security baselines
- Develop foundational observability infrastructure — logging, metrics, and tracing — giving builders and application teams at-a-glance visibility into system health
- Partner with SRE on platform reliability: availability, resilience, and performance of the underlying infrastructure
- Manage cloud vendor and tooling relationships at the engineering level, flagging risk and cost issues early
Benefits
- Ownership in what you help build (equity/RSUs)
- Comprehensive medical, dental, and vision plans
- 12 weeks of paid parental leave for all parents and 6+ weeks of additional paid leave for birthing parents
- Inclusive care for family planning, menopause, and midlife transitions
- Flexible vacation
- Paid holidays
- Sabbatical program
- Access to mental health resources, therapy and coaching
- 401(k) with 100% employer match (up to $6,000/year) in the U.S.
- Support for retirement savings globally
- Monthly stipends for work and wellness expenses
- Annual WIN bonus program
