Position Title:

Cellular Dev Ops Engineer. Duration: 6+ months with high possibilities of extension. Onsite:
Menlo Park, California 94025. Pay Range: $80-90 per hour.

We are seeking a Cellular-Dev Ops Engineer to join our Wearables Cellular team within Engineering Labs. This role sits at the intersection of public and private 5G/LTE cellular network engineering and Dev Ops automation, supporting the development and testing of next-generation wearable devices with cellular connectivity. You will be responsible for building, operating, and automating the infrastructure that enables end‑to‑end cellular testing – from RF signal path optimization and modem provisioning to CI/CD pipeline integration and automated IP management services.

This is a hands‑on engineering role that requires both hardware lab familiarity and strong software/automation skills.

• Cellular & RF Engineering (40%)
  • Private 5G/LTE Network Operations:
    Configure and maintain small‑cell/callbox infrastructure supporting , LTE, and ‑Red Cap across multiple frequency bands (n2, n5, n25, n66, B2, B5, B66)
  • RF Signal Path Management:
    Optimize RSRP/RSRQ/SINR measurements in shielded test environments; troubleshoot signal path issues including cabling, attenuation, and antenna configuration
  • Device Modem Provisioning:
    Manage modem calibration file provisioning, EFS (Embedded File System) operations, QMI/DIAG interfaces, and modem mode configuration
  • Cellular E2E Test Execution:
    Run and validate h/detach cycles, data path verification (ping/DNS/iperf3), GNSS integration, and multi‑RAT connectivity scenarios
  • Hardware Lab Operations:
    Stage and pair devices in shield boxes, manage rack equipment mapping, coordinate with callbox vendors, and maintain reference device baselines.
• Dev Ops & Automation (40%)
  • CI/CD Pipeline Integration:
    Configure and maintain automated test lanes – both blocking and non‑blocking – for cellular test suites within continuous integration frameworks
  • Infrastructure‑as‑Code:
    Manage network ACLs, network configuration pushes, proxy filters, and DNS automation pipelines
  • Service Development (Python):
    Build and maintain automated services such as IP management pipelines (static routing, DNS verification, asset tagging, batch processing)
  • Database & State Management:
    Administer MySQL databases, schema migrations, configuration management systems, and service state stores
  • Monitoring & Observability:
    Instrument services with time‑series metrics, manage alerting thresholds, respond to health alerts, and track SLA compliance
  • Inventory & Asset Management:
    Extend and maintain device inventory systems – CLI tools, reservation workflows, and device registration pipelines
• Test Framework & Tooling (20%)
  • E2E Test Development:
    Author config‑driven cellular E2E tests (JavaScript/Jest) covering LTE, , ‑Red Cap, and attach/detach scenarios
  • Callbox Integration Tooling:
    Develop and maintain Python/Thrift bridges for callbox queries and control RPCs
  • Modem Utility Libraries:
    Contribute to shared libraries for device‑side modem management (mode switching, airplane mode, cellular measurements)
  • Lab Network Tooling:
    Build and maintain lab network management features (PoE control, port management, VLAN allocation)

• 3+ years of experience in cellular/wireless engineering, Dev Ops, or a combined infrastructure role
• Private cellular network experience:
  Hands‑on with 4G LTE and/or 5G  – including cell planning, RF measurements (RSRP, RSRQ, SINR), and UE attach/registration flows
• Programming proficiency:
  Python (primary) with working knowledge of JavaScript; ability to write production services and test automation
• Linux systems administration:
  Comfortable with shell scripting, systemd services, networking (VLANs, static routing, iptables/nftables), and embedded device…
