Signal Processing Engineer
Job Description
This project aims to develop an intelligent measurement system based on a pulse
waveform library and machine learning regression analysis, designed for
automatic identification and quantitative prediction of ion concentration and
type in chemical solutions.
The position primarily involves creating and visualizing the pulse library,
controlling the PicoScope device, conducting dual-channel data acquisition,
extracting signal features, and training and evaluating regression models.
Responsibilities:
? Use the PicoScope 4000 series to acquire and record signals from chemical
solutions;
? Participate in the creation, optimization, and visualization of the pulse
waveform library;
? Implement automated data acquisition through PicoScope programming control;
? Process and extract features from experimental signals to build machine
learning datasets;
? Train and optimize regression models (e.g., XGBoost) for ion type and
concentration prediction;
? Perform result visualization, performance evaluation, and prepare technical
project reports.
Qualifications:
1. Master’s degree or above in Electronics, Signal Processing, Communications, Computer Science, or other related engineering fields;
2. Proficiency in Python programming and common data processing libraries;
3. Solidunderstanding of signal processing theories and methods (Fourier Transform, Wavelet Transform, filtering, and feature analysis);
4. Familiarity with experimental instrument control and data acquisition (e.g., AWG, PicoScope);
5. Knowledge of machine learning regression models and model optimization techniques;
6. Strong research habits, data analysis, and technical documentation skills;
7. Excellent independent thinking, problem-solving, and teamwork abilities;
8. Good written and spoken English communication skills for technical collaboration.
Preferred Qualifications:
? Experience using PicoScope or related projects;
? Background or experience in embedded development (e.g., ESP32, STM32);
? Familiarity with Git/GitHub for code management.
