Whirl AI - Principal Engineer, Cloud Infrastructure

• You have designed and deployed complex production infrastructure on AWS across every layer: networking, identity, compute, and data. • Experience architecting single-tenant platforms from the ground up and managing fleets of tenant environments at scale through their whole lifecycle, from provisioning to deletion. • Expert-level Pulumi. You have designed and scaled large Pulumi codebases and know the platform in depth, from its core concepts to its wider tooling. • Experience running containerized workloads (ECS, Kubernetes, or equivalent) and building the CI/CD pipelines that let the rest of engineering ship safely and fast. • Deep expertise in infrastructure security. You design for isolation, least-privilege access, and defense in depth. SOC 2 controls are the floor, and we expect skills well beyond them. • You build infrastructure that is observable, cost-effective, and performant. • Strong programming skills in Python, Go, or a similar language, enough to build and maintain the tools your work needs. • You use AI tools throughout your work to design, build, and operate infrastructure faster. • 7–9+ years in cloud infrastructure, platform engineering, or DevOps/SRE roles at a functional lead level. Your team has relied on you for its infrastructure decisions. • A high degree of independence. You lead the evolution of our architecture: design and document major changes, plan the work, delegate where it makes sense, and do the implementation yourself. • Production experience with GCP or Azure alongside AWS • Experience at an early-stage (seed to Series A) startup, especially having built cloud infrastructure from a small footprint • Cloud provider certifications (AWS Solutions Architect Professional, GCP Professional Cloud Architect, or Azure equivalents)
