Staff DSP Software Engineer

Tarana Wireless, Inc.•Milpitas, CA

7d•$155,000 - $200,000

About The Position

As a Staff DSP Software Engineer, you will work on the design, development, integration, and testing of RF calibration software modules for a next-generation fixed wireless broadband system. The primary focus is on layer 1 functionality of the proprietary 5G protocol, such as channel estimation, IQ imbalance correction, and LO leakage cancellation. Develop software for both the base station and user equipment of a broadband wireless access system, across various multicore DSP/ARM processors and real-time operating systems. Collaborate closely with L2/L3 software groups and FPGA/ASIC teams to deliver cross-layer features.

Requirements

MS or PhD in Electrical Engineering, with an emphasis in wireless communication and/or digital signal processing
10+ years of industry experience encompassing the ownership of design and implementation of signal processing algorithms on a DSP / ARM core running Linux or a RTOS
Industry experience needed in RFIC software development for wireless communication systems (such as 5G, LTE, WiFi, or similar proprietary protocols)
Strong understanding of RFIC impairments and compensating for the impairments using Real-Time SW
Experience needed in system integration and bring-up
Formal understanding of communication and signal processing theory and techniques, including OFDM communication systems, and a strong mathematical background in linear algebra
Strong background in C, C++, and Python programming
Experience with software development for multi-core embedded systems, including real-time operating systems (RTOS), memory and cycle optimization, caches, multi-threaded programming, inter-process communication, and HW/SW interaction
Comprehensive knowledge of one or more algorithms used in wireless communication systems, and their associated design and software implementation. Relevant experience could be in areas such as: RFIC impairments and compensations, SW development and validation; Calibration procedures for multi-antenna-based systems; Advanced array signal processing techniques, such as beam-forming and MIMO; Adaptive equalization, receiver synchronization, signal identification, and recovery
Experience with version control systems (Git, Gerrit, Gitlab), and issue tracking and collaboration systems (Jira, Confluence)

Responsibilities

Design of Calibration software architecture, HW/SW interfaces, APIs, and RFIC impairments correction algorithms and protocol state machines
Hands-on implementation in C/C++ of DSP software modules running under RTOS on a multi-core DSP architecture
System integration and debugging on complex hardware platforms
Mentorship of junior engineers, providing technical guidance and code review
Willing to learn continuously and collaborate with the team members.
