Responsibilities
- Architect and deliver software capabilities aligned with 3GPP LTE/NR procedures, protocols, state machines, timers, KPIs, and measurement semantics.
- Translate evolving 3GPP releases, operator requirements, and O-RAN priorities into software designs, reusable components, and test workflows.
- Develop automation and tooling for protocol conformance, interoperability, and performance validation across RAN-facing scenarios.
- Partner with systems, RF, protocol, product, customers, and partners to reproduce field issues, identify root causes, and deliver solutions.
- Create design documents, test plans, trace and PCAP interpretations, and technical notes.
- Help shape Open RAN architectures, interfaces, and multi-vendor wireless ecosystems.
Requirements
- Strong hands-on 3GPP LTE/NR expertise with a clear RAN focus, including L1/L2/L3 procedures, scheduling, mobility, bearers, signaling, and performance metrics.
- Typically 8+ years of professional software engineering experience, with strategic scope and impact valued alongside tenure.
- Strong C/C++ coding skills and/or modern Python for automation and tooling.
- Experience developing in Linux environments.
- Ability to debug distributed and real-time systems using logs, traces, protocol analyzers, KPIs, timing analysis, and performance investigation.
- Excellent written and verbal English communication skills.
- Preferred: RAN product development involving gNB/eNB, RAN performance optimization, or complex-system feature verification.
- Preferred: familiarity with O-RAN architecture and interfaces, including O-RU, O-DU, O-CU, fronthaul, and RIC concepts.
- Preferred: experience with CI/CD, test frameworks, containers, or cloud-based deployment environments.
- Preferred: 3GPP standards work or experience implementing features from evolving specifications.
