## Responsibilities

As a Senior IT & Infrastructure Engineer at ZaiNar, you will be the engineer keeping our Belmont engineering organization running, owning the compute infrastructure, CI/CD systems, monitoring, lab equipment, and internal IT services that engineering depends on every day. You will work hands-on across Linux administration, build pipelines, virtualization, AWS, lab operations, and tier-1 internal support, and partner closely with our 5G DevOps counterpart in Romania on shared infrastructure standards. This is a broad, hands-on role for someone energized by being the person engineers come to when things need to work.

JOB RESPONSIBILITIES

Infrastructure & Operations

  * Manage ZaiNar's compute infrastructure, including on-site lab equipment (Linux hosts, Jenkins servers, lab gear) and cloud resources.

  * Administer Linux hosts across the engineering environment, including SaltStack-based configuration management and NFS.

  * Create and operate virtualized resources, including Docker containers and KVM hosts.

  * Maintain backup and disaster recovery systems for managed Linux hosts.

  * Support core engineering SaaS tools (1Password, GitHub, GitLab, Cursor, etc.).

  * Provide operational support for ZaiNar's robotics setup, including integration of robotic testing and test results into engineering workflows.




CI/CD & Build Systems

  * Build and maintain CI/CD pipelines in GitHub and Jenkins for firmware and host image work, ensuring build consistency, automated linting, testing, and versioned artifact creation.

  * Integrate quality gates into pipelines using SonarScanner, Pytest, and other linting tools to maintain code quality standards.

  * Integrate hardware-in-the-loop (HITL) testing into firmware and host image build automation pipelines.




Monitoring & Alerting

  * Operate and evolve ZaiNar's Grafana observability stacks across infrastructure and testing environments, covering data ingest, visualizations, storage, and alerting.

  * Implement and troubleshoot alerts for system health conditions including power states (battery vs. wall power), UPS auto-shutdowns, full disks, and other infrastructure faults.




AWS & Cloud Operations

  * Provide AWS organization-wide support, including new account creation, periodic security audits, and cost analysis reporting.




Internal IT Support

  * Provide internal helpdesk support across hardware, software, and account issues for the engineering organization.

  * Manage internal account creation and host configuration workflows.

  * Coordinate with external IT partners and vendors on compliance, vendor management, and IT-adjacent engineering projects.

## Requirements

MUST HAVE ATTRIBUTES/SKILLS

  * 5+ years of experience in IT operations, systems administration, DevOps, or infrastructure engineering, with hands-on responsibility across both IT and engineering systems.

  * Strong Linux system administration skills (Bash), including configuration management (SaltStack, Ansible, or similar), NFS, and backup and disaster recovery.

  * Hands-on experience with virtualization, including Docker and KVM.

  * Working experience operating CI/CD pipelines in GitHub and Jenkins, including build automation, testing integration, and artifact management.

  * Working experience operating Grafana-based monitoring and alerting in production environments.

  * Familiarity with cloud administration at the organization level, including account management, security, and cost reporting (AWS preferred).

  * Comfort providing tier-1 internal IT support to a technical engineering team.

  * Based in the Bay Area, with on-site presence at our Belmont, California office at least 3 days per week.




SHOULD HAVE ATTRIBUTES/SKILLS

  * Experience coordinating with external IT vendors and managing compliance-adjacent IT projects (security audits, vendor management).

  * Experience operating in a regulated or compliance-sensitive engineering environment.

  * Exposure to early-stage or high-growth startup environments.




NICE TO HAVE ATTRIBUTES/SKILLS

  * Experience supporting firmware or embedded engineering teams, including hardware-in-the-loop (HITL) test integration into build pipelines.

  * Familiarity with 5G or LTE telecommunications at a working level.

  * Operational experience with lab equipment, test rigs, or robotics infrastructure in an engineering organization.

  * Working familiarity with code quality and static analysis tooling (SonarScanner, Pytest).

  * Familiarity with Elasticsearch operations (legacy ZaiNar systems; may require migration or retirement).
