ABOUT THE ROLE We are looking for a Infrastructure/Software Engineer (Mid-Level/Senior) for the Compute team at VTEX. This team owns the platform's shared compute infrastructure: EKS clusters (including Dark Kitchen), the migration of the legacy Beanstalk environment, the internal networking layer (Private Link, VPC), traffic balancing (Janus, NLB/ALB), GitOps (ArgoCD), and the Core API. You will work on one of the company's most critical engineering challenges today: unlocking the definitive migration from legacy Beanstalk to EKS, while maintaining reliability and zero downtime for dozens of teams dependent on this infrastructure. ABOUT THE TEAM The Compute team is part of VTEX's Core Platform, ensuring the reliability, scalability, and performance of the compute infrastructure supporting the platform for thousands of stores. As part of a recent reorganization, the team is focused on consolidating the next generation of compute infrastructure, reducing technical debt from legacy platforms, and raising the self-service standard for teams that rely on it. WHAT YOU WILL DO • Migrate and modernize critical infrastructure: Work directly on migrating workloads from legacy Beanstalk to EKS, managing networking, IAM, and functional parity. • Build for scale: Design and maintain compute and networking components (Private Link, load balancers, Core API) used simultaneously by multiple teams. • Operate critical production systems: Ensure high availability and resilience of the shared compute infrastructure, including participating in on-call rotations. • Evolve GitOps and IaC: Maintain and evolve ArgoCD/Argo Rollouts and the team’s infrastructure as code. • Cross-team collaboration: Act as a technical focal point for internal teams (Checkout, MasterData, Dark Kitchen, Traffic, among others) relying on Compute infrastructure. WHO YOU ARE • Experienced backend/platform engineer with a solid track record operating and evolving Kubernetes/EKS infrastructure. • Hands-on experience with production AWS (VPC, IAM, load balancers, Auto Scaling/Beanstalk). • Strong knowledge of distributed systems and networking (TCP/IP, DNS, proxies, inter-service communication). • Comfortable with legacy systems in transition: experience migrating workloads between compute platforms is a major plus. • Familiarity with GitOps
