Senior Software Engineer - 5G Devices at Viasat | LAYIQ

Responsibilities

Modular Software Architecture & Design
Design and implement modular software architectures with reusable building blocks, for devices that operate on NTN with Viasat's satellites
Develop software abstraction layers (HAL) and middleware that decouple application logic from modem hardware implementations
Create flexible, configurable software frameworks that support multiple device variants (many devices could have capabilities in addition to 5G, based on the target market), form factors, and deployment scenarios
Define clear interfaces and APIs between software modules to enable independent development, testing, and evolution of components
Balance architectural flexibility with performance requirements in resource-constrained embedded environments
5G Chipset Integration & Device Driver Development
Integrate 5G modem solutions from industry-leading vendors (Qualcomm, MediaTek, Intel) into device platforms and develop reference designs
Develop and maintain device drivers within the Linux kernel that support modem interfaces used in 5G technology (PCIe, USB, SDIO, UART)
Implement low-level software to control modem initialization, configuration, power management, and runtime behavior
Work with vendor Board Support Packages (BSP) and customize them for Viasat's specific hardware and use case requirements
Resolve challenging hardware-software integration faults
Optimize performance for latency, throughput, power consumption, and system stability
Reference Design Development
Design and maintain reference software architectures that serve as templates for partner-developed devices
Create comprehensive SDK packages including libraries, sample code, documentation, and build tools for OEM/ODM partners
Develop "golden reference" implementations demonstrating guidelines for building 5G NTN enabled devices compatible with Viasat’s network
Provide technical guidance and support to external device manufacturers using reference designs
Ensure reference architectures are well-documented, maintainable, and follow industry standards (3GPP, GSMA)
Balance reference design completeness with flexibility to accommodate diverse partner and market

requirements
