Software Engineer, Cloud Infrastructure

About the Role

As a Software Engineer on Sierra’s Cloud Infrastructure team, you’ll own the foundation that every Sierra customer runs on. That includes our multi-tenant environments, where most of our customers and data live, and our isolated single-tenant environments for highly regulated enterprises. Sierra is expanding quickly across AWS and GCP, in regions across North America, Europe, and Asia-Pacific. We expect to roughly double our number of deployments over the next year.

Responsibilities

• Design, build, and operate Sierra’s cloud infrastructure across AWS and GCP (and soon Azure) using Terraform and Kubernetes.
• Simplify and standardize our deployments so that adding a new region or environment is repeatable and predictable.
• Stand up and operate new multi-tenant regions and single-tenant environments for customers with strict regulatory or isolation needs.
• Help build and run compliant environments, including our FedRAMP deployment.
• Own and improve deploys and releases across our fleet, investing in tooling and developer experience so engineers can ship quickly and safely.
• Build security guardrails that give enterprise customers confidence in our shared multi-tenant environment.
• Work with our BYOC (Bring Your Own Cloud) team to make Sierra easy to deploy into customers’ own cloud environments.
• Drive reliability across the platform through observability, incident response, root cause analysis, and postmortems.
• Write production code, mostly in Go, to automate infrastructure and replace manual work with durable systems.

Qualifications

• 6+ years of hands-on software or infrastructure engineering experience, including building and operating production systems at scale.
• Broad infrastructure experience on at least one major cloud (AWS, GCP, or Azure).
• Deep expertise in at least one layer of the stack (such as compute, orchestration, networking, or deploys), plus interest in owning adjacent layers.
• Hands-on experience with infrastructure as code (Terraform preferred) and container orchestration (Kubernetes).
• Strong coding skills and a bias toward automation and tooling. Go experience is a plus.
• A pragmatic, scrappy approach to evolving prototypes into production-ready systems.
• Curiosity and flexibility to adapt to new clouds, tools, and customer requirements.
• A degree in Computer Science or a related field, or equivalent professional experience.

Nice to Have

• Experience running infrastructure across multiple clouds and many regions or environments.
• Experience with compliance-driven environments (FedRAMP, SOC 2, HIPAA, or financial services).
• Experience building deploy systems, CI/CD, or internal developer platforms.
• Experience deploying software into customer-managed cloud environments.
• An SRE background or experience leading reliability and incident management programs.
• Experience with distributed databases such as DynamoDB or Spanner.
• Experience at a fast-paced startup or on a small infrastructure team with broad scope.
