Senior Wireless Network Design Engineer

As a Senior Wireless Network Design Engineer, you will lead the design, planning, and optimization of wireless networks supporting E-Space’s LEO satellite constellation. You will own critical aspects of radio access network (RAN) design, drive technical trade studies, and influence system-level architecture decisions. This role requires close collaboration with systems, orbital, and core network teams to ensure scalable, high-performance, end-to-end solutions.

You will act as a technical leader within the network design domain, contributing to strategy, mentoring engineers, and helping define best practices for non-terrestrial 3GPP networks.

What you will do:

• Network Planning, Design, and Optimization
• Lead frequency planning activities to mitigate interference through advanced frequency reuse strategies
• Own cell planning activities, including determination of cell center locations, cell density, bandwidth allocation, and service duration based on subscriber density, traffic models, and service requirements
• Lead beam management design to create, optimize, and maintain planned cells on the ground
• Define, monitor, and optimize key performance indicators (KPIs), accounting for dynamics unique to LEO satellite networks
• Satellite and System-Level Coordination
• Lead satellite scheduling strategies for the LEO constellation to optimally serve ground cells
• Conduct and review feasibility analyses for multiple technical configurations, including frequency of operation, bandwidth, and cell size
• Own link budget analyses for satellite-to-ground and ground-to-satellite links, including margin analysis and sensitivity studies
• Work closely with Systems Engineers, Orbital Engineers, and Core Network teams to drive cohesive system architecture and trade-offs
• Technical Leadership
• Provide technical guidance and mentorship to junior and mid-level engineers
• Contribute to the definition of network design methodologies, tools, and best practices
• Support system integration, testing, and field trials with expert-level analysis and recommendations

Technical Requirements:

• 3GPP Protocols
• Deep understanding of 5G NR, LTE, and NB-IoT specifications, including non-terrestrial network (NTN) considerations
• Radio Physics
• Strong understanding of Doppler shift compensation and timing advance (TA) implementation for LEO satellite communications
• Simulation Tools
• Advanced experience with MATLAB, Atoll, and NS-3 for network modeling, simulation, and performance evaluation
• Hardware
• Strong familiarity with phased array antennas and beamforming techniques

What you bring to this role:

• Master’s or PhD in Electrical Engineering with a focus on Wireless Communications
• 5 years of experience in Radio Access Network (RAN) engineering is a must
• Proven experience leading complex technical analyses and design efforts
• Strong system-level thinking and the ability to influence cross-functional technical decisions
• Excellent analytical, problem-solving, and communication skills

Bonus Points:

• Experience with greenfield RAN deployments
• Familiarity with orbital engineering fundamentals and satellite constellation concepts
• Experience working with 3GPP Non-Terrestrial Networks (NTN)

Additional Requirements

This is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.
