全职 Data Scientist 工作, 薪水 up to SGD 6,000, OPHIR MANUFACTURING SOLUTIONS PTE. LTD. Central Region (Singapore) 公司招聘中 - Ricebowl

Location: [Singapore/ Remote / Hybrid]
Department: Data Science / AI / R&D
Reports To: Chief Scientific officer
Employment Type: Full-time

About the Role

We’re hiring a mid-level Data Scientist to help build signal processing algorithms and machine learning models for automated feature detection in digital time-series data. You’ll operate at the intersection of DSP and applied ML, transforming raw sensor streams into reliable, high-accuracy detection capabilities. If you enjoy building detection algorithms from the ground up, optimizing feature extraction pipelines, and applying ML to real-world signal data, this role is for you. Experience with biomedical or physiological signals is a strong plus.

Key Responsibilities

• Design, develop, and validate signal processing workflows and ML models for automated feature detection in time-series data
• Extract, engineer, and optimize features from raw digital signals using DSP techniques (filtering, resampling, segmentation, spectral analysis, artifact/noise mitigation, synchronization)
• Apply machine learning and deep learning approaches (classification, regression, anomaly/change-point detection, sequence models, or 1D CNNs/RNNs) to improve detection accuracy, robustness, and generalization
• Conduct rigorous model evaluation, ablation studies, hyperparameter tuning, and benchmarking against rule-based or classical baselines
• Collaborate with data engineers and software teams to productionize algorithms, ensuring scalability, reproducibility, and seamless integration into Azure-based pipelines
• Maintain comprehensive experiment tracking, version control, and documentation for all signal processing and ML work
• Translate product, research, or clinical requirements into technical solutions and communicate findings clearly to cross-functional stakeholders
• Stay current with academic and industry advancements in time-series ML, DSP, and applied AI

Qualifications

• 2–4 years of experience as a Data Scientist, ML Engineer, or Research Scientist working with time-series or signal data
• Strong foundation in digital signal processing (sampling theory, aliasing, FIR/IIR filtering, FFT/spectral analysis, windowing, resampling, noise/artifact handling)
• Hands-on experience applying machine learning techniques to feature detection in signal or time-series data
• proficiency in Python and scientific computing ecosystems (NumPy, SciPy, pandas, scikit-learn, PyTorch or TensorFlow)
• Experience developing and running ML workflows in Microsoft Azure
• Statistical reasoning and ability to debug complex signal-ML pipelines

Preferred

• Direct experience processing biomedical/physiological signals (ECG, EEG, EMG, PPG, respiratory, IMU, etc.)
• Experience with advanced time-series ML architectures
• Knowledge of MLOps practices (model versioning, CI/CD for ML, drift monitoring, Azure ML pipelines, MLflow/W&B)
• Publications, open-source contributions, or portfolio projects in signal processing or time-series ML
• Academic or industry background in biotech, digital health, medical devices, neuroscience, or applied research
• A passion for sports and exercise like golf, running, yoga etc
