IT Infrastructure Engineer

About the role

Sierra is seeking a hands‑on IT Infrastructure Engineer to scale its internal systems during a period of rapid growth. As the second member of the IT Engineering team, you will partner with the IT Lead, GRC Lead, and Platform Engineering to build, automate, and operate the infrastructure that powers day‑to‑day operations.

Key responsibilities

• Iterate on and improve internal tools that power IT and security workflows.
• Deploy a Data Loss Prevention (DLP) solution and integrate it into automated enforcement pipelines.
• Build API‑driven integrations between internal systems and the compliance automation platform.
• Design and scale internal infrastructure using code and infrastructure‑as‑code practices.
• Develop and maintain internal tools and services that improve 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.

Required profile

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

What we offer

• Flexible (unlimited) paid time off.
• Medical, dental, and vision benefits for you and your family.
• Life insurance, disability benefits, and retirement plan (depending on country).
• Parental leave and fertility/family‑building benefits through Carrot.
• Lunch, snacks, coffee, and a discretionary benefit stipend.
• Free alphorn lessons.
• Eligibility to participate in Sierra’s equity plans.
