About the Role As an engineer in the Infrastructure department at Alchemy, you will design, deploy, and continuously improve the infrastructure powering our blockchain developer platform — serving 100+ chains, billions of daily requests, and over $150B in annual transactions. The Infrastructure team provides the infrastructure, tooling, and expertise needed to allow Alchemy engineers to ship, scale, and operate high-quality products in a fast, safe, and cost-efficient manner. What You'll Do - Architect and operate scalable, self-healing infrastructure leveraging Kubernetes, Terraform, and cloud-native tools across multi-region deployments. - Drive AI enablement across engineering — ensuring repos, tooling, and workflows are optimized for agentic development with tools like Claude Code, Cursor, and Codex. - Build AI-powered infrastructure tooling and automation (e.g., automated K8s upgrades, IaC plan analysis, cost optimization advisors, MCP servers, n8n workflows). - Build and maintain internal developer platform (IDP) capabilities for self-service deployments, observability, and reliability. - Develop observability frameworks using Prometheus and Grafana for metrics, dashboards, and alerting. - Lead incident management with blameless post-mortems; define and enforce SLIs, SLOs, and error budgets across services. - Design and manage multi-cloud, multi-region network architecture — VPC design, IPAM, DNS (Cloudflare), cross-cloud connectivity, security groups, and edge-proxy/istio gateway configuration. - Collaborate with security teams to embed compliance into infrastructure, including IaC scanning and runtime protection. - Provide technical leadership and mentorship to elevate the team's operational capabilities. What We're Looking For - 5+ years as an Infrastructure Engineer focused on reliability (SRE, Production Engineer, Platform Engineer). - Experience driving company-wide reliability efforts, including SLO frameworks and error budget policies. - Strong profici
