Job Description and Requirement/Responsibility

We are seeking a Wireless Network R&D / Software Engineer to design, develop, test, and improve mobile core network software for Private Mobile Networks.

The successful candidate will contribute to 3GPP-compliant mobile core functions, translating telecom specifications into maintainable, reliable, and production-ready software.

This role combines hands-on software engineering, network protocol research, cloud-based test environment development, interoperability testing, fault analysis, and technical documentation.

KEY RESPONSIBILITIES

You will support R&D and software development for mobile core network products, with responsibilities spanning software design, protocol implementation, cloud-based testing, quality improvement, and technical documentation.

Mobile Core Software Design & Development

Design and implement mobile core network functions using Go, with opportunities to apply Rust where suitable.
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.

Experience:

Experience developing commercial software.
Implementation experience using the Go programming language.
Basic knowledge of Linux and IP networking.
Knowledge of virtualization technologies such as Docker.
Knowledge of cloud computing and cloud-based development or testing environments.
Team development experience using Git.
Strong logical problem analysis, technical communication, and collaboration skills.
