The Department: Enterprise Infrastructure

The Enterprise Infrastructure team owns the internal technology ecosystem that supports Gemini's offices and employees. The team operates as a unified engineering and service organization, combining front-line support excellence with DevOps-driven platform engineering under a single mandate. Our enterprise technology strategy fuels business growth through an engineering-first approach by delivering a modern, secure, and scalable foundation for seamless collaboration, efficient operations, and future-ready innovation. By emphasizing operational excellence, continuous improvement of existing systems, and strategic automation – including Infrastructure as Code, GitOps workflows, and AI-augmented operations – we position IT as an engineering discipline whose impact extends across the department and the broader organization.

The Role:

Senior Enterprise Infrastructure Engineer

As a Senior Enterprise Infrastructure Engineer, you will serve as a technical leader and force multiplier across the full breadth of Enterprise Infrastructure – from end-user support excellence to backend platform engineering and automation. You will apply DevOps methodologies to drive the design, implementation, and continuous improvement of the systems that underpin Gemini's global workforce. This includes owning strategies and execution for endpoint management, user identity and access lifecycle, internal tooling, Infrastructure as Code, CI/CD pipelines, and AI-augmented operational workflows. You will define and track key metrics, communicate trends and capacity insights to leadership, and make strategic decisions about tooling adoption, vendor relationships, and architectural direction with an awareness of how these decisions impact teams and stakeholders beyond Enterprise Infrastructure. A core expectation of this role is that you approach problems with an eye toward scalability and sustainability, building systems that reduce manual toil, improve reliability, and position the team for rapid growth. You are expected to critically evaluate existing systems and processes, challenging assumptions, identifying inefficiencies, and driving improvements to legacy workflows with the same rigor applied to new builds. You will act as a mentor and escalation point for others, fostering a culture of engineering rigor within support operations and a culture of user empathy within engineering work. The ideal candidate has deep experience across both operational support and DevOps-driven infrastructure, thrives in ambiguity, and is energized by the challenge of consolidating legacy tooling into modern, automated, GitOps-driven workflows. They bring a pragmatic approach to adopting emerging capabilities – including agentic AI – and are motivated by building solutions that scale beyond their immediate team to benefit the broader organization.

• Design and operate CI/CD pipelines for infrastructure changes, tooling, and endpoint configurations.
• Lead endpoint management platform migrations, including policy authoring, GitOps-managed profiles, and fleet-wide telemetry.
• Design and implement agentic AI workflows to augment IT operations, applying context engineering principles to enable reliable, bounded automation and validations.

Minimum Qualifications:

• 5+ years of progressive experience in enterprise IT, infrastructure engineering, or a DevOps-focused support capacity.
• Strong proficiency with macOS fleet management at scale using MDM platforms.
• Hands-on experience with Infrastructure as Code and configuration management tooling.

• Deep experience with identity and access management platforms (Okta, Google Workspace, Active Directory), including SSO, SCIM, Device Assurance Policies, MFA, and user lifecycle automation.
• Working knowledge of CI/CD pipelines (GitHub Actions or equivalent) and Git-based development workflows.
• Solid understanding of networking fundamentals.
• Experience with AWS cloud services in a production or internal-tooling context.
• Proven ability to communicate complex technical concepts to both technical and non-technical audiences, including leadership.
• Experience mentoring junior engineers and contributing to team culture, hiring, and process improvement.

Preferred Qualifications:

• Experience in fintech, crypto, or regulated financial services environments.
• Experience with FleetDM and osquery for endpoint telemetry, compliance, and GitOps-managed device configuration.
• Experience designing agentic AI harnesses and workflows or applying context engineering techniques to augment operational processes (e.g., Claude Code, OpenCode, LLM-driven automation).
• Proficiency in Go, Python, and/or Swift for internal tooling development.
• Hands-on experience deploying reliable tools via Containerization and Orchestration (Docker, Kubernetes/EKS).
• Experience managing 1,000+ user accounts across a globally distributed workforce.
