Project Description

The Broadband team is developing next-generation Cable Access solutions, including the industry’s first software-based CCAP platform — CableOS — and a cloud-native CMTS solution.

These products help cable operators deliver high-speed internet, video, and voice services to millions of users. A key focus is CableOS, which enables providers to replace traditional hardware-based network equipment with a flexible cloud-based solution, significantly reducing infrastructure and maintenance costs.

The platform is built on a modern microservices architecture and runs on general-purpose CPUs without requiring specialized ASIC hardware. This allows the software to operate both on bare-metal servers and private cloud environments, providing scalability, flexibility, and easier deployment.

CableOS is one of the pioneers in software-defined networking (SDN) for DOCSIS technologies, bringing cloud-native benefits and operational efficiency to telecom and broadband providers.

The GlobalLogic team is responsible for software development, as well as manual and automated testing of the solution.

Job Responsibilities:

• Design and implementation of network oriented application (Linux, userspace)
• A strong emphasis is put on generic design with memory and processing considerations as mandatory guidelines
• Design and implement new modules and features, as well as evolve existing ones
• Integrate with hardware components, ability to communicate with vendors regarding integration process and issues
• Regular communication with the remote and international teams
  
  Job Requirements:
• 3+ years' development  experience in C and C++
• Knowledge and experience in multithreading
• OOP knowledge

We are looking for an experienced iOS Developer to join our team and help us support and evolve a complex production iOS application.

• Work with an existing codebase where RxSwift is still widely used
• Participate in the gradual migration from RxSwift to Swift Structured Concurrency
• Use async/await and modern Swift concurrency patterns where appropriate

• Refactor and improve existing code while keeping production stability
• Collaborate with product, design, QA, and backend teams
• Review code, share knowledge, and help improve engineering practices
• Investigate and fix bugs, performance issues, and technical debt
