Integrate and automate workflows across various SaaS platforms, utilizing REST APIs, OAuth flows, and scripting to eliminate repetitive manual tasks and improve system reliability. Design and implement CI/CD pipelines (e.g., GitHub Actions, Concourse CI) to ensure smooth, automated deployments and consistent application of infrastructure changes. Develop internal tools, custom scripts, and services (e.g., in Go, Python, Swift) to manage, monitor, and scale our global device fleet, including macOS and ChromeOS devices managed via MDM solutions (Jamf, Google MDM) and, where needed, Windows endpoints. Collaborate closely with the support-focused team members, serving as the escalation point for complex technical challenges, and implement automated solutions to reduce future support burdens. Engineer and maintain integrations with AWS services (e.g., EC2, S3, Cloudfront, CloudWatch) to ensure efficient, scalable, and secure cloud operations. Evaluate and adopt emerging technologies (e.g., Containerization: EKS) to further enhance system performance, resiliency, and security. Support identity management and user lifecycle tasks through Okta, Google Workspace, Active Directory, and other related IAM systems, working to automate user management at scale. Develop and maintain technical documentation, FAQs, and runbooks to ensure knowledge sharing and empower team members with clarity and confidence. Partner with cross-functional teams to identify operational pain points, drive continuous improvement initiatives, and advance Gemini’s overall technology ecosystem. Minimum Qualifications: Bachelor’s degree in a technical field or 4-8 years of experience in a DevOps-focused IT/infrastructure role.

Proficiency in scripting and programming languages (e.g., Python, Go, Swift) and working with REST APIs. Understanding of identity and access management technologies (Okta, Google Workspace) and authentication protocols (OAuth). Detail-oriented and capable of juggling multiple priorities in a dynamic environment. Excellent communication and documentation skills, with the ability to explain technical concepts to both engineering and non-engineering audiences. Proactive self-starter who can identify, plan, and implement solutions with minimal guidance. Preferred Qualifications: Experience in a startup, fintech or finance support. Understanding of SSO implementations (i.e. Okta). Experience with Linux. Strong experience with macOS. Experience managing 2500+ devices through MDM. Experience managing 1000+ user accounts. Experience with Go, Python, and Swift. Experience with Configuration Management (Ansible, Chef, Puppet or Salt). Experience creating and maintaining CI/CD pipelines.
