• Ability to work with time-series data; familiarity with core signal processing concepts (filters, spectral analysis/FFT, peak detection, windowing).
• Domain exposure to wearable biosignals and real-world noise and artifacts.
• Experience developing back-end tools for data processing and analysis.
• Proficiency in C and/or Python programming languages.
• Solid grounding in statistical inference (e.g., study design, hypothesis testing, regression analysis, bootstrapping), with the ability to choose appropriate methods and articulate trade-offs.
• Familiarity with machine learning libraries such as scikit-learn, TensorFlow, PyTorch, Keras, etc.
• Strong communication skills with a track record of concise, visual storytelling and documentation.
• Demonstrated ability to think innovatively and adapt to changing requirements while consistently producing high-quality reports within tight deadlines.
• Experience with version control systems (e.g., Git), CI/CD pipelines, and cloud computing platforms (e.g., AWS).
• Experience querying data in modern data warehouses (e.g., Snowflake).
