Senior Principal​/Architect Engineer Software

Job Summary

We are seeking a Module FW Integration Engineer – For Module Integration and Cellular Certification to drive software validation, automation, and the cellular certification lifecycle for our wireless products. This role bridges embedded application development, network emulation, and supports global carrier certification. You will validate embedded applications, build Python automation pipelines, and utilize industry-standard network simulators to troubleshoot 4G/5G routing platforms against carrier and regulatory standards.

• Embedded Development & Validation:
  Develop, modify, and validate embedded Linux-based applications, ensuring seamless communication between network layers, peripheral hardware, and cellular modems.

• Test Automation:
  Design and maintain robust Python/Bash scripting frameworks to automate image loading, device provisioning, network simulator configurations, and data collection loops.

• Network Emulation & Testing:
  Configure and manage high-end network emulators/call boxes (Keysight UXM, Rohde & Schwarz CMX/CMW, Amarisoft) to recreate complex 4G LTE and 5G  environments. Build cabled multi‑UE distribution setups.

• Image Management:
  Configure, track, and load software/firmware builds onto engineering prototypes and production routing units for formal testing.

• Advanced Troubleshooting:
  Isolate and debug network, software, and protocol layer issues via log diagnostics. Perform hardware characterization using RF lab equipment (spectrum analyzers, signal generators, power meters, network analyzers).

• Global
  
  Collaboration:
  
  Act as the primary technical point of contact for external third‑party test labs, Carrier Certification Teams and Industry Certification bodies, and chipset vendors globally.

• Regulatory Filings:
  Prepare technical documentation and test data for FCC/ISED (North America) and regional Asian bodies such as JPN (Japan), KC (South Korea), TW (Taiwan), and ANZ (Australia/New Zealand).

• Industry Compliance:
  Coordinate and oversee PTCRB and GCF (Global Certification Forum) testing cycles from initial submission to final listing.

• Documentation:
  Compile and maintain Technical Construction Files (TCF), user manual compliance statements, and Declaration of Conformity (DoC) records.

• Carrier Acceptance & Testing Support

• Support the Carrier Acceptance Testing (CAT) process for major North American carriers (Verizon, AT&T, T-Mobile) and key Asian operators.

• Work directly with test houses to reproduce, log, and debug issues found during conformance testing.

• Analyze protocol and RF logs (using tools such as QXDM, Wireshark, or equivalent) to help isolate software or hardware issues.

• Test Lab & Vendor Coordination

• Quote, submit purchase orders in support of FCC, CE, TW, KC, JPN, AU and NZ country regulatory testing (archive reports/certifications).

• Quote, submit purchase orders in support for industry and carrier certifications testing and certifications (archive reports/certifications).

• Act as the daily interface with third‑party test labs and Telecommunication Certification Bodies (TCBs).

• Ship samples and accessories, track test progress, resolve blocking issues in the lab, and ensure test reports are delivered accurately and on time.

• Manage device inventory, SW and cellular module firmware, and device configuration for certification.

Required Skills & Qualifications

• Embedded Linux Systems:
  Proven experience developing and debugging application software within embedded architectures and Linux environments.

• Python & Scripting:
  Strong proficiency in Python and Bash for hardware/simulator API interaction and test automation.

• Wireless Protocols:
  Solid understanding of 4G LTE and 5G  (Standalone/Non‑Standalone) software stacks and 3
  
  GPP protocol layers (NAS, RRC, PDCP, RLC).

• Networking Foundations:
  Robust knowledge of core routing protocols (TCP/IP, BGP, OSPF, VPNs, VLANs) and memory management.

• Diagnostic & RF Equipment:
  Mastery of protocol analysis tools (Wireshark, QXDM, QPST) alongside hands‑on experience programming RF equipment (spectrum/network analyzers, power meters) and running automated test scripts.

• Familiarity with industry standards (3
