Description
As a Cellular Physical Layer Firmware Engineer on this team, you will be at the center of the embedded 5G/4G/multimode cellular firmware effort within a silicon design group responsible for crafting and productizing powerful cellular SoCs. This position requires someone comfortable will all aspects of embedded software development, who thrives in a multifaceted multi-functional organization, is not afraid to debate ideas openly, and is flexible enough to change directions on constantly evolving requirements!

Responsibilities

In this role you will be a key member of the Cellular Layer1 Control Software team with following responsibilities:
Specify, design, and implement Layer1/PHY Control Software/ Firmware of an innovative mobile wireless communications system.
Implement key scheduling, control processing in tight timeline, latency, and energy constraints.
Lead design and development activities, problem solve and influence project level decisions.
Work with other Firmware and Protocol Stack Engineers, Systems Engineers, and Product Architects to collaborate on design and requirements, interface definitions and new features.
Assist in the development of pre-silicon emulation systems/virtual platforms and use them for pre-silicon Layer1 Control SW design and verification.
Plan, improve, and manage embedded firmware/software with strict timeline requirements and be involved in all stages of code development, from design to release of the product.
Participate in all phases of complete software development lifecycles.
Gather 3GPP specifications and vital requirements and apply them in design and code development.
Define methodologies and standards.

Minimum Qualifications

6+yrs of hands-on L1/PHY Software/Firmware experience in Cellular 3G/4G/5G and strong experience in embedded real-time control.
Very good proficiency with C and/or C++, compilers, build, and source code control tools.
Experience with silicon prototyping, emulation systems, and virtual platforms.
Proficiency in debugging embedded software systems.

Preferred Qualifications

Bachelor or Master or higher degree in Computer Science, Embedded System Engineering, or Electrical/Information Engineering with several years of working experience or PhD in a relevant field with some years of proven experience.
Good understanding of software engineering principles, and core computer science fundamentals.
Proven understanding of computer architecture with particular emphasis on the HW/SW interfaces of high-speed communication subsystems.
Experience with memory-constrained Real-Time Operating Systems (RTOS) and concurrent programming would be a plus.
Scripting language experience (eg. with Python or similar) would be desirable
