HashiCorp Infrastructure Automation
Master infrastructure as code and secrets management with HashiCorp — from Terraform basics to Vault enterprise operations. The essential path for DevOps, platform, and cloud infrastructure engineers.
What Does a HashiCorp Infrastructure Engineer Do?
HashiCorp engineers automate the provisioning, configuration, and security of cloud infrastructure using the industry-standard HashiCorp toolchain. Terraform is the de facto standard for infrastructure as code across AWS, Azure, and GCP, while Vault is the leading solution for secrets management in enterprise environments.
"Terraform is the most widely adopted infrastructure as code tool in the industry. Organizations that have adopted it report 70% faster infrastructure provisioning and significantly fewer human errors in production."
Core Responsibilities
- Write and maintain Terraform configurations for multi-cloud infrastructure
- Design Terraform module libraries and manage state backends at enterprise scale
- Implement Vault for dynamic secrets, PKI, and encryption-as-a-service
- Build CI/CD pipelines that integrate Terraform and Vault for GitOps workflows
- Enforce policy-as-code using Sentinel and OPA
- Manage secrets lifecycle: rotation, leasing, revocation, and audit logging
Essential Skills
- Terraform: providers, resources, modules, workspaces, remote state, backends
- Terraform Pro: Sentinel policies, module composition, drift detection, enterprise features
- Vault Core: auth methods, secret engines, policies, dynamic secrets
- Vault Ops: HA deployment, replication, DR, performance tuning, seal/unseal
- Integrations: AWS, Azure, GCP, Kubernetes, GitHub Actions, GitLab CI
