Senior Infrastructure Engineer, Cloud

At Webflow, we're building the world's leading AI-native Digital Experience Platform, and we're doing it as a remote-first company built on trust, transparency, and a whole lot of creativity. This work takes grit, because we move fast, without ever sacrificing craft or quality. Our mission is to bring development superpowers to everyone. From entrepreneurs launching their first idea to global enterprises scaling their digital presence, we empower teams to design, launch, and optimize for the web without barriers. We believe the future of the web, and work, is more open, more creative, and more equitable. And we're here to build it together. About the Role We're looking for a Senior Infrastructure Engineer to improve reliability and stability of Webflow's customer-facing, production infrastructure, serving millions of page views per hour. Our product is used by over 2 million users world-wide across 190 countries, and you'll help ensure our platform is secure and scalable for these users as tens of thousands of projects are launched on Webflow each month. • Location: Remote-first (Argentina) • Permanent, full-time employee (this is not a contractor position) • Application Information: • Application deadline: applications accepted on an ongoing basis until position is closed and filled • This posting is for a new position. As an Senior Infrastructure Engineer you will: • Own and evolve the cloud substrate that Webflow's product and engineering teams depend on, including our compute layer, EKS fleet, networking, and cloud operations across AWS and GCP. • Design and maintain the networking fabric that connects Webflow's services, ensuring reliability, security, and scalability across our cloud environments. • Build and enforce guardrails around IAM, SCPs, and scoping permissions that keep infrastructure secure and auditable without slowing engineers down. • Drive FinOps across Webflow's cloud footprint, owning cost attribution, right-sizing recommendations, and surfacing waste before it becomes a problem. • Partner with Infra teams on instance type selection, capacity planning, and right-sizing decisions that impact application performance. • Build and maintain AI-powered automation that improves how we manage cloud infrastructure, from policy-as-code and drift detection to LLM-assisted runbook generation. • Help define the culture of this growing team as it expands its international presence. About you You'll thrive as a Senior Infrastructure Engineer if you: • Have a background as an infrastructure or cloud engineer with an enthusiasm for automation and code, or a background as a software engineer with deep enthusiasm for cloud infrastructure and distributed systems. • Have 5+ years of experience owning and operating cloud infrastructure in a customer-facing environment that allows for little to no downtime. • Have deep hands-on experience with AWS and a strong opinion on what good cloud operations look like. • Have experience managing Kubernetes clusters at scale, including upgrades, node group management, autoscaling, and cluster add-on lifecycle. • Have experience with infrastructure-as-code tools like Pulumi or Terraform, and a strong preference for changes made through code, not consoles. • Have experience navigating multi-region or multi-cloud environments on AWS or GCP. • Stay curious and open to growth, demonstrating a proactive embrace of AI, and actively building and applying fluency in emerging technologies to elevate how we work, drive faster outcomes, and expand collective impact. It would be a bonus if you had even one of the following: • Experience with Karpenter, cluster autoscaler, or other Kubernetes-native scaling tooling. • Experience with GCP infrastructure alongside AWS in a multi-cloud environment. • Experience building AI-assisted infrastructure tooling, including cost optimization loops, anomaly detection, or policy-as-code with LLM assistance. • Experience contributing to multi-region architecture including data residency, regional failover, or latency-based routing. You Are: • Collaborative: You possess a collaborative spirit, thriving when working with both your immediate team and cross-functional partners. • Strategic thinker: You're a strategic thinker, adept at defining clear business needs and evaluating solutions to make informed build-versus-buy decisions. • Comfortable with ambiguity: You navigate ambiguous situations with ease, gathering data and making progress even with incomplete information or unclear requirements. If you don't meet 100% of the above qualifications, you should still seriously consider applying. Studies show that you can still be considered for a role if you meet just 50% of the role's requirements. Our Core Behaviors: • Build lasting customer trust. We build trust by taking action that puts customer trust first. • Win together. We play to win, and we win as one team. Success at Webflow isn't a solo act. • Reinvent
