Job Description & How to Apply Below
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.
In this role, you will build, operate, and automate the infrastructure enabling 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 position requiring both hardware lab familiarity and strong software/automation skills.
Key Responsibilities- 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 cabling, attenuation, and antenna configurations.
- 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 vendor tools, and maintain reference device baselines.
- CI/CD Pipeline Integration: Configure and maintain automated blocking and non-blocking test lanes for cellular test suites.
- Infrastructure-as-Code: Manage network ACLs, configuration pushes, proxy filters, and DNS automation pipelines.
- Service Development (Python): Build and maintain automated services like 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 CLI tools, reservation workflows, and device registration pipelines.
- Callbox Integration Tooling: Develop and maintain Python/Thrift bridges for callbox queries and control RPCs.
- Modem Utility Libraries: Contribute to shared device-side modem management libraries (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. - Linux Systems Administration: Shell scripting, systemd services, networking (VLANs, static routing, iptables/nftables), and embedded device interaction (adb, fastboot, serial).
- Infrastructure Automation: Experience with at least two: CI/CD pipelines, IaC, configuration management, database administration, or monitoring systems.
- Full‑Stack Debugging Mindset: Ability to troubleshoot from RF signal levels and modem firmware up to service RPCs and database queries.
- Experience with Amarisoft, Keysight, Rohde & Schwarz, or similar small‑cell/callbox platforms.
- Familiarity with Qualcomm modem tooling (QXDM, QMI, DIAG, NV item provisioning, EFS management).
- Exposure to wearable or IoT device development and testing.
- Experience with Thrift/gRPC service development and service mesh architectures.
- Knowledge of MCTP/NCSI or other baseboard management protocols.
- Background in test automation frameworks (Jest, pytest, or similar).
- Familiarity with network security tooling (ACL generation, firewall policy management).
- Experience operating shielded/anechoic test environments.
