System Architect

This is a fully remote position, open to applicants in Poland.

📋 Description

• Define the system architecture for 5G/6G RAN and Core, ensuring alignment with 3GPP, O-RAN Alliance, ETSI NFV, and SCF FAPI/nFAPI specifications.

• Develop and execute multi-threaded real-time/embedded systems, demonstrating expertise in design, documentation, implementation, and unit testing.

• Construct system architecture as software applications that function within virtualized environments (Kubernetes, Docker), guaranteeing critical connectivity and high availability.

• Design and implement end-to-end Network/System Architecture based on an Open RAN model with comprehensive recommendations for 3GPP and O-RAN features.

• Generate complete technical blueprints that encompass RAN functional splits, control/user plane separation, and cloud-native deployments.

• Mentor engineering teams in the deployment of scalable, secure, and high-performance network functions (DU, CU, RIC, Core).

• Offer technical assistance to cross-functional teams in feature implementation and establish integration, verification, and validation strategies.

• Conduct system-level performance evaluations, capacity planning, and design enhancements.

• Ensure architectural adherence to open interfaces (O-RAN fronthaul, midhaul, backhaul) and interoperability with multi-vendor ecosystems.

• Contribute to standardization initiatives and monitor emerging features in Releases 17/18/19+ and pre-standard 6G projects.

⛳️ Requirements

• Strong background in C/C++ programming along with debugging skills for practical implementation tasks.

• Extensive knowledge of multi-threaded real-time/embedded systems, with proven skills in design, documentation, implementation, and unit testing.

• Substantial experience with disaggregated and cloud-native RAN implementation architecture.

• Familiarity with the ETSI NFV framework, MANO, and cloud-native orchestration (Kubernetes, CNF design).

• Profound understanding of 3GPP specifications for 5G NR and Core (R15–R18, early 6G) and O-RAN standards.

• Strong grasp of O-RAN architecture, interfaces (OFH CUPS Planes, F1, E1, E2, A1, O1, O2), and RIC functions.

• Demonstrated experience in designing large-scale telecom systems (RAN, Core, OSS/BSS or SMO integration).

• Knowledge of version control, bug tracking, and CI/CD systems.

• Understanding of security, reliability, and QoS in telecom-grade deployments.

• Exceptional communication skills with the ability to collaborate across multi-disciplinary teams.

• Proficient in English (spoken/written).

🏝️ Benefits

• Competitive salary package that increases with your experience and contributions.

• Access to a world-class telecommunications knowledge base and comprehensive training resources.
