Wearables Connectivity (Engineering Labs) Team Network Infrastructure & Labs - Cellular Connectivity Role Overview We are seeking a Cellular-DevOps 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 DevOps 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.

Key Responsibilities Cellular & RF Engineering (40%)
Private 5G/LTE Network Operations : Configure and maintain small-cell/callbox infrastructure supporting NR SA, LTE, and NR-RedCap 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 NR attach/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

DevOps & 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, NR SA, NR-RedCap, 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)

Required Qualifications:
3+ years of experience in cellular/wireless engineering, DevOps, or a combined infrastructure role
Private cellular network experience : Hands-on with 4G LTE and/or 5G NR - 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 interaction (adb, fastboot, serial)
Infrastructure automation : Experience with at least two of: CI/CD pipelines, Infrastructure-as-Code, configuration management, database administration, or monitoring systems
Debugging mindset : Ability to troubleshoot across the full stack - from RF signal levels and modem firmware to service RPCs and database queries

Preferred Qualifications:
Experience with Amarisoft or similar small-cell/callbox platforms (Keysight, R&S)
Familiarity with Qualcomm modem tooling (QXDM, QMI, DIAG, NV item provisioning, EFS management)
Exposure to wearable/IoT device development or 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
