Cloud Infrastructure Engineer

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.

- 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.

- 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 proficiency with observability stacks: OpenTelemetry, Prometheus/Grafana.

- Deep experience with cloud infrastructure (AWS/GCP), Kubernetes, and multi-region architectures.

- Skilled with Terraform, Helm, and GitOps workflows (e.g., ArgoCD) with an automation-first mindset.

- Experience leveraging agentic development tools (Claude Code, Cursor, Codex) and workflow automation (n8n) to accelerate IaC and build internal tooling is a strong plus.

- Solid networking fundamentals — VPC design, DNS, IPAM, security groups, cross-cloud connectivity, and service mesh (e.g., Istio) experience is a plus.

- Strong cross-functional communicator across SRE, security, and product engineering.

- Blockchain infrastructure, distributed systems, or high-throughput RPC experience — not required but a plus.
