Our client, a mid-stage technology company in the Bay Area operating in a fast-paced engineering environment, is seeking a Senior IT & Infrastructure Engineer. This role is responsible for keeping the engineering organization’s infrastructure and internal systems running reliably, including compute infrastructure, CI/CD systems, monitoring platforms, lab equipment, and internal IT services.

The position is highly hands-on and requires strong Linux and infrastructure engineering expertise, with additional responsibility for tier-1 internal IT support. You will collaborate closely with global DevOps and engineering counterparts to maintain shared infrastructure standards and ensure operational continuity across environments.

This role is best suited for someone who enjoys being the primary go-to engineer for infrastructure reliability, automation, and internal systems support.

• Manage compute infrastructure including on-site lab environments (Linux hosts, Jenkins servers, lab equipment) and cloud resources
• Administer Linux-based systems across engineering environments using configuration management tools (e.g., SaltStack or similar)
• Build and manage virtualized infrastructure including Docker containers and KVM-based systems
• Maintain backup and disaster recovery systems for Linux hosts and critical infrastructure
• Support engineering SaaS tools (e.g., GitHub, GitLab, identity/security tools, developer platforms)
• Support robotics or hardware-integration lab environments and workflows where applicable

• Develop and maintain CI/CD pipelines using GitHub and Jenkins for firmware and system builds
• Ensure build reliability, automated testing, linting, and artifact versioning
• Integrate quality and validation gates using tools such as SonarScanner, Pytest, and related frameworks
• Support hardware-in-the-loop (HITL) testing integration into automated pipelines

• Operate and enhance monitoring and observability systems (Grafana-based stacks)
• Manage dashboards, alerting, and system telemetry across infrastructure environments
• Implement and troubleshoot alerts for infrastructure health (power states, disk usage, UPS systems, hardware faults, etc.)

• Support AWS organization-level administration, including account provisioning and governance
• Assist with security reviews, cost monitoring, and usage reporting

• Provide tier-1 internal IT support for engineering teams (hardware, software, access, and account issues)
• Manage account provisioning and system configuration workflows
• Coordinate with external IT vendors and partners on compliance and operational needs

• 5+ years of experience in IT operations, systems administration, DevOps, or infrastructure engineering
• Strong Linux administration skills (Bash), including configuration management, NFS, and backup/recovery systems
• Hands-on experience with virtualization technologies such as Docker and KVM
• Experience building and maintaining CI/CD pipelines using GitHub and Jenkins
• Experience operating monitoring/alerting systems such as Grafana in production environments
• Familiarity with AWS or similar cloud platforms, including account-level administration and cost monitoring
• Ability to provide tier-1 internal IT support in a technical engineering environment
• Strong troubleshooting, debugging, and analytical skills
• Comfortable working in fast-paced, engineering-driven environments
• Based in the Bay Area with onsite presence required at least 3 days per week

• Experience working with external IT vendors and compliance-related IT processes (audits, governance, security reviews)
• Experience in regulated or compliance-sensitive engineering environments
• Background in high-growth or early-stage startup environments

• Experience supporting firmware or embedded engineering workflows
• Exposure to telecom or IoT environments (e.g., 5G/LTE systems)
• Experience managing lab infrastructure, test rigs, or robotics environments
• Familiarity with code quality tools such as SonarScanner and Pytest
• Exposure to Elasticsearch or legacy observability systems

• Full-time, direct hire position
• Hybrid schedule with onsite requirement (3+ days per week, Mid Peninsula Bay Area)
• Role focused on hands-on infrastructure ownership and engineering support across systems and tooling
