Systems & Technology Research Signal Processing and Systems Modeling Engineer in Woburn, Massachusetts

STR is hiring a Signal Processing and Systems Modeling Engineer to be part of a multidisciplinary team of researchers and engineers dedicated to developing cutting-edge technologies with significant and immediate impact on our national security. We believe that each employee has a unique set of skills, experiences, and perspectives that are essential to providing our customers with innovative solutions.

This position seeks a candidate with versatile skills in signal processing, cyber-physical systems modeling, and statistical data analysis, to aid in the development of novel cyber threat mitigation technologies. We seek a candidate who is curious and motivated to work within a team structure to develop technical solutions in a rapid prototyping and results-driven environment. Our culture takes pride in developing impactful technologies through collaborative teamwork, while maintaining high standards of craftsmanship and quality.

We encourage applicants who are proficient at programming in at least one high-level languages (e.g. C/C, Python and/or MATLAB) for building models and algorithmic technologies in support of cyber threat mitigation. The development of these models and technologies is benefited by sound understanding and hands-on experience with implementing signal processing techniques (signal analysis/filtering), statistical modeling, electromagnetic propagation modeling, and/or digital communications systems modeling. Since our software technologies are focused towards cyber operations, an understanding of cyber vulnerabilities and their effects on software systems is valuable. We expect the tools and techniques we develop and deliver to meet standards of quality, maintainability, and reuse. Therefore, experience with sound software engineering principles and software unit test methodologies is valuable.

Duties will include:

  • Developing signal processing, electromagnetic and communications models for cyber physical systems

  • Developing algorithms for vulnerability research and threat analysis

  • Analyzing measured structured and non-structured data using statistical, machine learning, and/or optimization techniques

  • Implementing models and algorithms in in Python, C/C, and/or MATLAB

  • Ensuring quality of implemented algorithms and models through the use of unit-level and system-level tests

  • Participating in laboratory and field tests to collect and analyze experimental data to support the verification, validation, and improvement of technical solutions

  • Communicating technical ideas and implementations through reports and presentation


  • Ability to obtain a Top Secret (TS) Security Clearance

  • MS in Electrical Engineering, Physics, Mathematics, Computer Science, or related field with 2 years of experience.

  • Proficiency in C/C or Python/MATLAB

  • Experience in implementing signal processing algorithms and statistical models

  • Experience developing and giving technical presentations

Desired Skills:

  • Active Security Clearance at the Top Secret (TS) level

  • Familiarity with software build and scripting tools (e.g. make, bash), virtualization technology (e.g. Docker)

  • Understanding of electromagnetics, machine learning, optimization models

  • Understanding of common software vulnerabilities, and secure programming principles

  • Experience using collaborative source code management tools (Git, Subversion)
