The Department : Platform Security

The Platform Security team secures Gemini's infrastructure through service hardening and by developing and supporting a suite of foundational tools. We provide secure-by-default infrastructure, consumable security services, and expert consultation to engineering teams for secure cloud and non-cloud infrastructure.

The Role : Staff Enterprise Security Engineer (Client Platform)

The Platform Security team builds and delivers security foundations and paved paths for Gemini's corporate endpoints and workforce. As a Staff Corporate Security Engineer focused on client platforms, you will build security services, tools, and automation while hardening our macOS fleet, securing endpoint management platforms, and implementing configuration-as-code security guardrails. This is a hands‑on engineering role where you'll write production code daily using Go, Swift, Objective‑C, and Python—not just configuration management.

You'll design and build endpoint security platforms that scale across our organization. This role requires deep technical expertise in macOS security internals, strong software development skills to build production services, and systems engineering experience with MDM and configuration management. You will partner closely with IT, Engineering, and GRC teams to enable secure device management while maintaining least‑privilege access and zero‑standing‑privilege models for endpoints.

This role is required to be in person twice a week at either our San Francisco, CA or New York City, NY office.

Responsibilities

• Build and maintain security services, tools, and automation using Go, Swift, Objective‑C, and Python
• Design and implement endpoint security controls for macOS environments using system extensions, network extensions, and native security frameworks
• Create reusable libraries, frameworks, and platforms that enable secure‑by‑default patterns for client devices
• Develop automated security monitoring, scanning, and remediation services for endpoint events
• Build CI / CD pipelines for security software deployment and configuration‑as‑code validation
• Implement and manage MDM platforms (Jamf, Fleet) and configuration management systems (Salt, Munki)
• Architect binary authorization, DNS filtering, and application control solutions at scale
• Partner with Engineering, IT, and GRC teams on architecture decisions and provide security consultation
• Participate in on‑call rotation for critical security incidents and endpoint security issues
