What is the difference between Modem System Test Engineer vs Modem Firmware Engineer?

AspectModem System Test EngineerModem Firmware Engineer
Primary FocusTesting and validation of modem systems and hardwareDeveloping and optimizing modem firmware and software
Required SkillsTesting methodologies, hardware troubleshooting, knowledge of communication protocolsEmbedded programming, firmware development, C/C++ skills
Work EnvironmentTesting labs, hardware integration environmentsSoftware development environments, embedded systems
Common CertificationsISTQB, hardware testing certificationsEmbedded systems certifications, C programming certifications

While both roles involve working with modems, the Modem System Test Engineer primarily focuses on testing and validating hardware and system performance, whereas the Modem Firmware Engineer concentrates on developing and maintaining the firmware that runs on modems. Both roles are essential in the modem development lifecycle and often collaborate closely.

What are Modem System Test Engineers?

Modem System Test Engineers are professionals who design, develop, and execute tests to ensure the reliability and performance of modem systems, which enable wireless communication in devices such as smartphones and IoT gadgets. They work with hardware and software teams to identify, troubleshoot, and resolve issues related to connectivity, data transmission, and network compatibility. Their responsibilities often include automating test cases, analyzing logs, and validating modem features against industry standards. This role is crucial in ensuring that wireless products deliver high-quality user experiences and comply with regulatory requirements.

What are the typical challenges faced by a Modem System Test Engineer when working with new device releases?

Modem System Test Engineers often encounter challenges related to ensuring compatibility and performance across a wide range of networks and devices, especially during new device launches. Rapidly evolving hardware and software can introduce unexpected bugs, requiring thorough regression and exploratory testing. Additionally, collaborating with cross-functional teams, such as development, QA, and carrier partners, is essential to address integration issues and meet tight project deadlines. Staying adaptable and maintaining clear communication are key to overcoming these obstacles.

General Summary:
Job Description
** This position is not eligible for Qualcomm immigration sponsorship. **
Location Technology System Test Engineer
Tests and validates location technology systems spanning software and hardware components, including GNSS positioning, WWAN-based location (LTE/NR), WLAN-based positioning (Wi-Fi), sensor-based positioning, and geofencing solutions. Interprets wireless, sensor, and positioning specifications to design and execute system-level test plans, scenarios, scripts, and procedures. Performs system integration, functional, and regression testing across lab and field environments.
Validates multi-sensor location solutions that combine GNSS, cellular, Wi-Fi, and device sensors (e.g., inertial and motion sensors) for improved continuity, accuracy, and robustness. Documents system-level defects using standardized bug tracking tools and collaborates closely with software, systems, and algorithm teams to drive issue resolution.
Leverages agentic AI-assisted workflows to improve test execution efficiency, automate log post-processing, and accelerate result analysis for complex location systems. Develops and executes test programs to evaluate new location features and system modifications, ensuring accuracy, stability, and performance across GNSS, WWAN, WLAN, and sensor-assisted positioning methods.
Additional Job Description
Principal Duties and Responsibilities
  • Executes system-level testing for location technologies including:
    • GNSS and assisted GNSS
    • WWAN-based positioning
    • WLAN-based positioning
    • Sensor-based positioning, including inertial and motion-assisted location
    • Multi-technology sensor-fusion-based location solutions
  • Builds foundational understanding of end-to-end location systems, including interactions among GNSS, modem (WWAN), WLAN, sensors, middleware, and application layers.
  • Designs and executes test plans validating functional behavior, continuity, and stability of sensor-assisted and fused location outputs.
  • Collects and analyzes logs, traces, sensor data, positioning outputs, and requirements to identify system-level issues impacting:
    • Location accuracy
    • Availability and continuity
    • Transition behavior between GNSS, WWAN, WLAN, and sensors
  • Performs log and trace analysis across GNSS, WWAN, WLAN, and sensor subsystems to isolate root causes of positioning failures or drift.
  • Gathers and correlates information from multiple sources (sensor data, wireless logs, system traces) to troubleshoot integrated location stack issues.
  • Uses agentic AI tools to assist with:
    • Automated or semi-automated execution of location system tests
    • Post-processing of large sensor and wireless log datasets
    • Pattern detection, trend analysis, anomaly identification, and result summarization
  • Assists in validating that fixes or tuning changes correctly address sensor-based or fused-location issues without introducing regressions.
  • Identifies and documents defects related to sensor behavior, fusion stability, or interaction with GNSS/WWAN/WLAN positioning.
  • Executes basic field and lab tests involving walking, driving, indoor, and transition scenarios where sensor-assisted positioning is exercised.
  • Communicates location system issues and results clearly to software, systems, and algorithm teams.
  • Manages individual test tasks, priorities, and deliverables with close supervision.
  • Coordinates with technical leads to confirm adequate coverage and execution time for sensor-assisted and hybrid location validation.
  • Develops and maintains functional and system tests ensuring correct behavior of sensor-based and multi-technology location features.

Level of Responsibility
  • Works under close supervision while independently completing assigned location system test tasks.
  • Responsible for own work with limited impact; errors typically result in schedule or re-test implications.
  • Uses verbal and written communication to convey routine, factual information related to location testing and results.
  • Completes multi-step testing tasks requiring basic planning and prioritization.
  • Exercises limited creativity to troubleshoot system-level location issues, including those involving sensor integration.
  • Applies deductive problem-solving techniques using defined diagnostic processes and limited data analysis.
  • Uses agentic AI as a productivity and analysis aid, not as a substitute for engineering judgment.

Minimum Qualifications:
• Bachelor's degree in Engineering, Information Systems, Computer Science, or related field.
