• Research 3GPP specifications and translate relevant requirements into software design, implementation, and test requirements.
• Develop maintainable, reliable, and operable software components for Private Mobile Network products.

Protocol & Network Engineering

• Work with mobile core protocols and interfaces such as S1AP, PFCP, GTP, Diameter, RTP, and SIP.
• Apply Linux and IP networking knowledge to support network software development, integration, and troubleshooting.
• Analyze network behavior using logs, packet captures, and tools such as Wireshark.

Testing, Quality & Interoperability

• Perform unit testing, integration testing, interoperability testing, and load testing.
• Build cloud-based test environments on GCP and conduct validation under realistic operating conditions.
• Identify, analyze, and resolve defects through systematic fault investigation and quality improvement activities.

Cloud-Native & DevOps Engineering

• Use Docker and related virtualization technologies to support development and test environments.
• Apply Git-based team development practices, including code reviews and design reviews.
• Contribute to cloud-native development practices, with opportunities to work with Kubernetes and scalable deployment environments.

Documentation & Team Collaboration

• Write clear technical documentation covering design decisions, software behavior, test results, and operational considerations.
• Collaborate with engineers, researchers, product stakeholders, and partner teams to deliver high-quality network software.
• Communicate technical findings clearly through logical problem analysis and structured reporting.

REQUIRED QUALIFICATIONS

Education:

• Bachelor's or Master's degree in Computer Science, Computer Engineering, Electrical Engineering, Telecommunications, Information Technology, or a related discipline.
