Job Description
Description:

On-site in Carlsbad, CA

 

Our client seeks a Senior Engineer who will operate as a Principal Investigator for a digital signal processing, sensing-centric development program. The role requires system-level expertise in mixed-fidelity simulation development and analysis for sensing systems, spanning signal acquisition, embedded processing, software, hardware, integration, and test. The engineer will serve as the technical authority for end-to-end simulation architecture, from sensing elements through data processing and system performance, while interfacing with customers and developing advanced simulation frameworks.

 

Due to federal security clearance requirements, applicant must be a United States Citizen with an active Secret clearance. Due to client requirements, applicants must be willing and able to work on a w2 basis. For our w2 consultants, we offer a great benefits package that includes Medical, Dental, and Vision benefits, 401k with company matching, and life insurance.

 

Rate: $100.00 to $120.00/hr. w2

Responsibilities:
  • Lead design, development, and validation of mixed-fidelity simulation frameworks across sensor phenomenology, signal acquisition, processing pipelines, and system performance.
  • Define simulation architecture strategies for next-generation sensing systems, including sensor element selection, processing chain topology, and hardware/software partitioning.
  • Develop physics-based models of sensing elements, noise sources, and interference conditions.
  • Author validation plans and correlate simulation outputs with HIL, bench, and field test results.
  • Maintain modular, version-controlled simulation repositories with expanding model coverage and fidelity.
  • Develop and apply detection, estimation, filtering, spectral analysis, and statistical characterization algorithms.
  • Model signal chains end to end, including noise, interference, and environmental effects.
  • Define and evaluate processing performance metrics and translate findings for hardware and embedded software teams.
  • Validate models against measured data and close fidelity gaps through iterative refinement.
  • Serve as principal investigator and technical lead, aligning algorithm, embedded software, hardware, and systems teams.
  • Lead technical reviews including PDR and CDR, deliver simulation products, and provide peer review.
  • Identify capability gaps and drive roadmap improvements.
  • Mentor junior engineers in simulation methodology, signal processing, and analysis practices.
  • Interface with customers on methodology, assumptions, uncertainty quantification, and performance predictions.
  • Translate complex results into concise findings and technical reports for leadership and customers.
  • Support proposals by defining simulation scope, articulating discriminators, and contributing to SOW and BOE.
Experience Requirements:
  • B.S. in Electrical Engineering, Physics, Computer Engineering, or a related field. Advanced degree preferred.
  • 10+ years in modeling and simulation of sensing or signal processing systems with ownership of simulation frameworks.
  • Proficiency with MATLAB/Simulink and Python ecosystems such as NumPy, SciPy, and PyTorch.
  • Experience structuring large, maintainable simulation codebases.
  • Prior experience as a principal investigator or technical lead on a U.S. government or defense program with direct customer interaction.
  • Ability to obtain and maintain a Top Secret/SCI security clearance.
  • Willingness to travel up to 10%.
  • Ability to work on-site in Carlsbad, CA preferred or Tempe, CA.
  • Helpful: experience with RF, EO/IR, acoustic, or lidar sensors and phenomenological modeling; AFSIM; embedded or real-time DSP on FPGA or embedded CPUs; HIL integrated with bench or field test; MBSE and system performance budgeting; track record of publications or patents.
Education Requirements:
  • B.S. in Electrical Engineering, Physics, Computer Engineering, or a related field. Advanced degree preferred.
  • Active Secret Clearance or higher.
