Job description

Position Description

ISCO is seeking a Junior Wireless DSP / PHY Algorithm Engineer to support the modeling and evaluation of signal processing algorithms for wireless communication systems.

In this role, you will build and adapt MATLAB-based models of DSP and PHY algorithms, following guidance from senior engineers. Your work will include simulating algorithms in a system-level framework, analyzing time-domain IQ signals, and helping validate algorithm performance under realistic conditions.

You will work with both time-domain signal processing and OFDM receiver techniques. The role involves integrating algorithms (e.g., equalization, combining, interference mitigation) into larger simulation frameworks. While your primary tool will be MATLAB, familiarity with object-oriented programming principles (from Python or other languages) will help you adapt to MATLAB's object-oriented system framework.

This position is ideal for someone who is a proficient coder, deeply familiar with signal processing principles, and eager to implement and adapt algorithms in collaboration with senior engineers.

Education/Experience

MSEE or PhD in Electrical Engineering with emphasis on digital signal processing and wireless communication systems.

2-7 years of experience developing signal processing models, simulations, or algorithms for wireless or DSP systems.

Required Skills

• Strong proficiency in MATLAB programming, with experience building simulations or models of signal processing algorithms.
• Solid understanding of digital signal processing fundamentals, such as filtering, spectral analysis, and time/frequency domain concepts.
• Familiarity with wireless communication concepts such as OFDM, MIMO, channel modeling, and basic RF propagation.
• Experience with object-oriented programming (e.g., in Python, MATLAB, or another language) and ability to adapt these principles to MATLAB's system framework.
• Ability to translate algorithm descriptions or mathematical models into clean, well-structured MATLAB code.
• Familiarity with OFDM receiver techniques (e.g., channel estimation, equalization, or combining methods) is a plus.
• Experience contributing to system-level or link-level simulations is desirable.
• Good communication skills and ability to collaborate within a team.
• Strong curiosity and eagerness to learn and grow in wireless DSP algorithm development.

Additional Requirements

Occasional domestic travel in support of customer meetings or product trials is required. Travel is estimated at about 10% of the time.

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 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.
