Job Details

ISCO seeks a Senior Wireless Digital Signal Processing Engineer with a broad engineering skill set, innovative spirit, and desire to work in a fast-paced, entrepreneurial environment. As a member of the Development Team, you will be responsible for the design and implementation of DSP algorithms for the PHY layer and Digital Front-End (DFE) signal processing for 4G/5G communication systems. Engineering responsibilities will begin at the conceptual phase and extend through product design, optimization, and deployment. This is an excellent position for a talented, motivated, and experienced engineer seeking the opportunity to develop industry leading solutions.

Education/Experience

MSEE or similar with emphasis on digital signal processing for wireless applications, and a minimum of 5-7 years of related experience.

Necessary Skills

1. Must have demonstrated expertise in DSP algorithm modeling and development using MATLAB with the focus on time-domain IQ signal processing.

2. Experience implementing Digital Front-End (DFE) signal processing techniques, including digital filtering, crest factor reduction, digital predistortion, and digital upconversion/downconversion for 4G/5G systems.

3. In-depth knowledge of 4G/5G air interface; PHY layer algorithm design and simulation for OFDM systems; familiarity with wireless base station architectures.

4. Must be familiar with and understand basic RF concepts, ADC concepts, the concepts of radio frequency propagation, MIMO, beamforming, channel modelling, modulation and demodulation of wireless signals, basic RF components used in 4G/5G radio design.

5. Must be familiar with software development, FPGA development, algorithm implementation using fixed point models. Strong skills in the area of digital signal processing algorithm development, analysis and implementation.

6. Should have laboratory experience with test equipment, such as spectrum analyzers, network analyzers, signal generators, power meters.

7. Experience with algorithm testing and algorithm implementation using software defined radios is a plus. Proven ability to take projects from conception to design validation and final verification.

8. Good communication skills. Able to clearly and concisely communicate with team members, sales team, customers and management on issues concerning designs and other business issues.

9. Experience with patent disclosures and filings is a plus and will be part of the job.

10. Working knowledge of C/C++/Python is a plus.

Additional Requirements

1. Occasional domestic travel in support of customer meetings or product trials is required. The travel is estimated to be about 10% of the time.

2. Since ISCO makes equipment for cellular operators and cellular networks operate 24/7, on rare occasions some work (particularly during product trials) may have to be performed during off hours between 12am-4am or on weekends.

Location

This position is at ISCO headquarters in Schaumburg, IL. Remote candidates are also strongly considered given the right set of skills and experience.
