Jobs C

Requirements:

• Strong backend development experience with C++ (the bulk of the backend is built on a custom in-house framework)
• Hands-on experience with AWS, particularly S3
• Proficiency with Protobuf
• Experience deploying and operating services on Kubernetes, including performance-driven traffic routing to pods
• Performance engineering skills — hash-based routing, SSD-based caching, and memory-mapped files
• Solid systems / low-level fundamentals (there is no off-the-shelf framework to rely on — much of the stack is custom)
• Ability to work highly autonomously and drive work forward with minimal supervision
• Strong communication skills and experience working in distributed teams (Europe/Ukraine time zone; ~1–2 hours of daily overlap with a US-based team)
• Hands-on experience with AI-assisted development tools — e.g. Claude Code and Codex — including AI skills, plugins, and MCP (Model Context Protocol), with a clear understanding of how to boost personal productivity and code quality using AI tooling.

Nice-to-Have:

• Familiarity with OpenTelemetry / observability tooling
• Understanding of LevelDB SSTable concepts and sorted, time-keyed data structures
• Familiarity with Python (used only for a small metadata/auth service)
• Basic DevOps skills.

Key Responsibilities:

• Optimize the performance of the C++ data-streaming backend — efficient delivery of large recorded datasets to the browser
• Work on infrastructure-level optimizations: traffic routing to Kubernetes pods, hash-based routing, SSD-based caching, and memory-mapped files
• Operate within a custom data-handling stack — a C++ framework, a custom HTTP server, and a proprietary data format built on top of LevelDB SSTables and Protobuf
• Take ownership of performance work end-to-end, proactively identifying bottlenecks and driving solutions independently
• Collaborate with a primarily US-based team with ~1–2 hours of daily overlap, while working largely independently
• Participate in code reviews and design discussions.

About the Project:

You'll join the engineering team of a leading technology company building autonomous mobility and robotics systems. The team develops an internal data visualization platform — a "video and data player" that renders 3D scenes, lidar, and audio recorded by autonomous vehicles. This role sits on the performance work stream: the backend reads on-vehicle data stored in S3, deserializes it from a custom, time-keyed format, and streams it to the browser. The data-transfer service is implemented in C++, and most of the platform's performance gains are expected to come from the backend.

This is a long-term engagement for a strong systems engineer who enjoys low-level performance work and is comfortable ramping on a heavily custom stack with high ownership and minimal supervision.

• Bachelor’s Degree or Master’s Degree in Computer Science, Engineering, Software Engineering or a relevant field.
• 3+ years of experience in C++ software development.
• Experience with CAD, CAM, 3D engineering software.
• Strong analytical skills solving algorithmic, geometrical challenges.
• Strong communication skills and ability to explain protocol and processes with team and management.
• Ability to work independently and in a team environment.
• Current with industry trends, IT ops and industry best practices, and able to identify the ones we should implement.

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.
