IT Infrastructure Engineer

About Sierra

Sierra is the leading platform for customer-facing AI agents, working with many of the world's biggest brands to transform how they serve customers and grow their businesses. We are primarily an in-person company based in San Francisco, with growing offices across North America, Europe, and Asia.

We’re looking for a hands-on IT Infrastructure Engineer to help scale Sierra’s internal systems during a critical period of growth. You’ll be the second member of our IT Engineering team, partnering closely with our IT Lead, GRC Lead, and Platform Engineering team to build and operate the systems that support our company day-to-day.

This is an engineering-first role approaching IT through code, automation, and well-designed systems.

What You'll Do

In your first few months, you’ll focus on:

• Iterating on and improving internal tools that power IT and security workflows
• Deploying a DLP solution and integrating it into automated enforcement pipelines
• Building API-driven integrations between internal systems and our compliance automation platform

More broadly, you will:

• Design and scale internal infrastructure using code and infrastructure-as-code practices
• Build and maintain internal tools and services
• Improve and develop automation pipelines for provisioning, access management, and security controls
• Treat IT systems like software: versioned, tested, and continuously improved
• Partner with Platform Engineering and Security to implement scalable, programmatic solutions
• Create clear, durable documentation to support long-term scalability

What You’ll Bring

• Think of IT problems as engineering problems, and default to building over manual work
• Strong experience with identity platforms (Okta, Google Workspace, SSO, MFA, SCIM, OIDC)
• Experience deploying or managing DLP or related security solutions (e.g., ZTNA, Cloudflare)
• Extensive experience with IaC (Terraform)
• Comfortable writing code for automation (e.g., Python, Bash, or similar)
• Experience building internal tools or services that integrate via APIs
• Comfortable working with CI/CD concepts and automation pipelines
• Fluent in using and administering modern AI tooling
• Understanding of SaaS lifecycle management and compliance requirements
• Strong communication and documentation skills
• Comfortable operating independently in a fast-moving environment

Even Better...

• Background in software engineering or prior experience on a product engineering team
• Experience building internal platforms or developer tooling
• Familiarity with security tooling such as CASB, EDR, or MDM
• Experience with access audits, data residency, or compliance controls
• Experience deploying systems using AWS and infrastructure-as-code
