Excellent problem-solving skills, teamwork, and effective communication are critical soft skills for success in this role. These competencies ensure reliable network performance, minimize downtime, and facilitate seamless collaboration across technical teams in high-demand environments.

What are some common challenges faced by Senior Packet Core Engineers, and how can they be addressed?

Senior Packet Core Engineers often encounter challenges such as managing complex network integrations, ensuring high availability, and troubleshooting advanced issues in live mobile core networks. Staying updated with evolving technologies like 5G and virtualization can also be demanding. To address these challenges, engineers typically collaborate closely with cross-functional teams, participate in ongoing training, and implement robust monitoring tools to proactively identify and resolve potential issues. Strong problem-solving skills and continuous learning are essential for success in this dynamic role.

What is a Senior Packet Core Engineer?

A Senior Packet Core Engineer is a highly skilled telecommunications professional responsible for designing, implementing, and maintaining the packet core network infrastructure that supports mobile data services. Their role involves managing core network elements such as SGSN, GGSN, MME, and EPC nodes, ensuring reliable and efficient data transmission across 3G, 4G/LTE, and 5G networks. They also troubleshoot complex issues, optimize network performance, and may lead teams in deploying new technologies or upgrades. Senior Packet Core Engineers frequently collaborate with vendors, network architects, and other engineers to ensure seamless integration and high availability of services.

What is the difference between Senior Packet Core Engineer vs Network Operations Engineer?

Description:
As a Hardware-in-the-Loop (HIL) Engineer within General Motors' AV Core Infrastructure team, you will design, build, and maintain advanced HIL systems that accelerate validation of embedded controllers and perception systems across next-generation vehicles. You'll bridge mechanical, electrical, and software disciplines to deliver scalable, reliable, and maintainable test infrastructure enabling data-driven development of automated driving features.
You will collaborate with systems engineers, embedded software developers, integration labs, and operations teams to ensure our HIL platforms remain at the forefront of validation capability-powering the test flywheel that drives GM's future of safe, autonomous mobility.
Key Responsibilities
  • Design, build, and sustain modular HIL systems for ECU and subsystem validation across multiple vehicle platforms.

  • Develop scalable rack-based test solutions integrating power distribution, network infrastructure, and environmental management for high-availability operations.

  • Collaborate cross-functionally with Systems, Firmware, and Validation Engineering to define I/O mappings, harnessing, and test configurations.

  • Deploy automation and monitoring systems for bench health, including power cycling, network diagnostics, and logging infrastructure.

  • Drive lab capacity expansion projects, including facility layout, power/network planning, and thermal management.

  • Continuously innovate to improve efficiency, reusability, and modularity across the HIL fleet; contribute to design libraries and shared tools.

  • Complete bench bring up, parts ordering, and integration of components ranging from boards to sensors.

  • Support flashing and configuration changes and develop preventative maintenance processes to ensure bench fleet health.

  • Be hands on the ground for rapid responses to bench related issues.

Required Qualifications
  • Bachelor's degree in mechanical, Electrical, or Mechatronics Engineering-or equivalent hands-on experience in HIL, lab automation, or robotics integration.

  • 4+ years of experience in design, integration, and maintenance of hardware validation systems or HIL infrastructure.

  • Familiarity with ECU harnessing, power systems, and signal integrity best practices.

  • Competence with Linux CLI, networking (Ethernet, switches, VLANs), and power distribution.

  • Proven record of cross-functional collaboration, vendor management, and hands-on debugging of complex electromechanical systems.

Preferred Qualifications
  • Experience building or maintaining large-scale HIL or test automation systems supporting multiple ECUs or vehicle domains.

  • Familiarity with Python, CAN/LIN tools (Vector, Kvaser, etc.), and test automation frameworks.

  • Experience with thermal and EMI management, system grounding, and rack-level cable routing.

  • Knowledge of lab operations, EHS compliance, and facility management.
