Junior Wireless DSP​/PHY Algorithm Engineer

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

0–5 years of experience developing signal processing models, simulations, or algorithms for wireless or DSP systems.

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.

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 – 4 am or weekends.

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

Residency requirement: Candidates must be US Citizens or US permanent residents and reside in the US.

Reports to: Vice President - Engineering.
