About The Position

We are looking for our first IT Systems Engineer to join Braintrust. You will design, implement, and operate the infrastructure that keeps our team productive and our data secure as we scale past 100 people. This is an in-person San Francisco based role.

Requirements

You are deeply hands-on and comfortable owning systems end-to-end, not just coordinating vendors
You have strong experience with modern IT tooling such as MDM (Jamf or Kandji), cloud infrastructure (AWS), and identity providers (Okta, Google, or similar)
You understand that for a fast-moving AI company, security must be automated, integrated into workflows, and designed to scale
You thrive in ambiguous environments and are energized by building something from scratch
You have ideally been the first or early IT or Security hire at a high-growth startup
You can translate complex technical and security requirements into clear, actionable guidance for the rest of the company

Responsibilities

Design and deploy a scalable, zero-trust IT and security foundation that supports a high-performance, engineering-driven organization
Implement and manage a unified identity and access platform, including SSO, role-based access controls, and MFA across SaaS tools and cloud environments
Own the full lifecycle of our internal technology stack, including tool selection, onboarding, access management, automation of offboarding, and cost optimization
Establish baseline IT and security policies, documentation, and controls appropriate for a fast-growing startup
Build and operate incident response processes, including logging, alerting, and clear playbooks for handling security events
Identify gaps, manual processes, or security risks and proactively fix them without needing direction
