DSP Software
Developer

Embedded software development for electronics is one of our key expertise areas. Our engineers work with open and proprietary operating systems, creating firmware, bootloaders, BSP, system drivers and server software. Our solutions are applied in various industries: automotive, telecom, broadcasting, security, industrial automation and consumer devices. 

• Design and development of 4G/5G and NB-IOT SW on the base station.
• DSP implementation in C\C++ of wireless communication algorithms.
• Cooperation/Communication with other teams (ASIC, Platform Integration, System Test and IOT teams).
• Fixing defects and updating analysis results in the defect tracking system.
• Drive/Participate system-level analysis across teams to analyse complex issues.
• Proactively support customer issues and resolve same.

• Experience in algorithm design and optimisation for embedded applications, complexity analysis and mapping to vector signal processors, memory requirements, real-time vs non-real-time requirements, etc.

• Experience with C/C++ and/or Python for algorithm development, modelling (floating-point and fixed-point) and link-level simulation.
• English (Intermediate and higher).

• Experience with Matlab
• In-depth knowledge of wireless communication systems with hands-on experience in lab testing & characterization.
• Deep knowledge of communication system theory and signal processing to design algorithms related to channel state feedback, digital precoding and analogue beamforming, channel estimation, interference mitigation, MIMO detection, multi-user MIMO, timing and frequency recovery, automatic gain control, RF impairments estimation and correction, forward-error correction, OFDM, etc.
• Experience in chip bring-up, including lab equipment such as protocol test equipment, spectrum analysers, signal generators, power meters, etc.

• Knowledge of cellular communication standards and call flows 5G NR (FR1 and FR2), 4G LTE, link adaptation, and channel state information feedback.
