You will collaborate with systems engineers to refine algorithms and design firmware architecture that balances power, performance, and cost.

Responsibilities

• Implement key 3GPP digital signal processing algorithms interfacing with specialized cellular ASIC hardware.
• Work with systems engineers to refine signal processing algorithms for efficient firmware/hardware execution.
• Specify, design, and implement the firmware architecture for superior power, performance, and cost.
• Assist in the development of pre-silicon emulation systems/virtual platforms and use them for verification.
• Evaluate and implement tools for build, formal verification, and testing.
• Define methodologies and standard processes.

Requirements

• BS degree and 3+ years of relevant industry experience.
• Experience implementing digital signal processing algorithms using special purpose digital signal processing hardware or wireless physical layer channels.
• Deep understanding of software engineering principles and core computer science fundamentals.
• Proficiency in C and C++, compilers, build, and source code control tools.
• Experience with silicon prototyping, emulation systems, and virtual platforms.
• Solid understanding of computer architecture with emphasis on HW/SW interfaces of high-speed communication subsystems.
• Some experience with mainstream OS application level development and Python or Perl scripting.

Nice-to-haves

• Understanding of 5G and 4G 3GPP protocols.
• Familiarity with wireless communications.
• Significant experience with memory constrained Real Time Operating Systems (RTOS) and concurrent programming.

Benefits

• Comprehensive medical and dental coverage
• Retirement benefits
• Discounted products and free services
• Reimbursement for certain educational expenses including tuition
• Discretionary bonuses or commission payments
• Relocation assistance
