Your Role at impact.com : As we scale toward 600 product engineers, the infrastructure layer that powers everything - Kubernetes clusters, VPCs, compute pools, storage, shared services - becomes mission-critical. Right now, that infrastructure is the single point of failure for every developer-facing capability the platform team builds. You'll be the senior IC responsible for designing, deploying and operating that substrate. This is more than infrastructure management; it's production-quality software engineering applied to infrastructure. You'll build abstractions that let service teams specify their infrastructure requirements at a high level, then turn those into reliable, secure, performant deployments. This role sits at the intersection of deep cloud-native expertise and solid software engineering discipline. What You'll Do: Lead the design, deployment and operation of platform-layer infrastructure: VPCs, compute pools, storage, Kubernetes clusters, and the networking that connects them - translating configuration data into inputs for IaC modules provided by Cloud Operations. Own the monitoring and operation of managed pub/sub messaging systems (e.g. Kafka) that service teams depend on. Design and evolve abstractions that allow service teams to express infrastructure requirements at a high level, translating those into production-grade deployments with security and high availability baked in by default. Operate platform infrastructure at 99.9% uptime. Own the change management process for infrastructure changes and drive a > 95% change success rate. Build a strong post-incident learning loop. Work with Cloud Operations to consume their IaC modules and feed back operational lessons and enhancement requests. Maintain a clean module-consumer relationship that protects both functions. Anchor the technical standards for the Shared Services and Infrastructure team: code review quality bar, controller patterns, GitOps idioms, IaC consumption patterns and operational runbooks. Mentor junior engineers and set the bar for infrastructure software engineering. What You Bring: Software or infrastructure engineering experience, including operating production Kubernetes and cloud-native infrastructure. Strong software-engineering fundamentals and hands-on experience with Java. Deep Kubernetes expertise and comfort with Linux command line. Strong networking and cloud architecture fluency: VPCs, subnets, load balancing, security, service mesh interaction. Hands-on experience with IaC tools (Terraform) and GitOps tooling (Argo CD, Flux or equivalent). Solid experience participating in production incident response. You're comfortable being on-call for critical infrastructure. Working knowledge of observability fundamentals (metrics, logs, traces) and experience consuming platform observability backends. Experience mentoring junior engineers; you can set and maintain a technical quality bar. A Bachelor's or Master's degree in Computer Science, Engineering or related field, or equivalent professional experience. Hands-on…
