Role Overview

A development-focused role working with customer engineering teams and client R&D to develop, customize, integrate and optimize software for next-generation wireless systems. The engineer contributes production code, debugs protocol-stack behavior and turns field challenges into product enhancements.

Key Responsibilities

• Design, develop and enhance software features in wireless systems and protocol stacks using C/C++ and Python on Linux.
• Debug and root-cause complex issues across Layer 1 (PHY), Layer 2 (MAC/RLC/PDCP) and Layer 3 (RRC/NAS).
• Analyze signaling logs, traces, packet captures and performance metrics to resolve issues in customer deployments and integrations.
• Modify existing code and build new features to meet customer-specific requirements; build prototypes to validate new features.
• Develop APIs, tools, automation frameworks and diagnostics to improve productivity and system visibility.
• Participate in code reviews; contribute to software releases, validation and deployment of features into customer environments.
• Collaborate with client R&D to convert field findings into product improvements.
• Lead technical discussions with customers on protocol implementation, architecture and performance optimization.

Required Qualifications

• Bachelor's or master's degree in computer science, Computer Engineering, Electrical Engineering or a related field.
• 6+ years of software development experience in wireless communication systems.
• Strong C/C++ and Python skills; hands-on experience in Linux environments.
• Solid understanding of 4G LTE, 5G NR or 5G-Advanced, with deep knowledge of 3GPP Layer 1 3 protocols (especially RRC and NAS).
• Hands-on development in one or more protocol-stack layers (PHY, MAC, RLC, PDCP, RRC, NAS) with ownership of design, implementation, debugging and maintenance.
• Strong root-cause analysis using logs, traces, packet captures and signaling analysis.
• Ability to understand and extend existing codebases; experience with code reviews and collaborative development.
• Strong problem-solving, communication and collaboration skills.

Preferred Qualifications

• Experience with modem software, protocol-stack development, wireless infrastructure, device testing or network simulation platforms.
• Embedded, real-time or firmware development experience.
• Experience building software tools, automation frameworks and APIs; knowledge of wireless test and measurement systems.
• Customer-facing experience on complex technical projects; experience leading technical investigations.
• Exposure to 5G-Advanced, NTN, Open RAN or 6G technologies.

Ideal Candidate

Combines deep wireless protocol expertise with strong hands-on software development skills, enjoys solving difficult technical problems, and is comfortable working directly with customers and R&D teams.
