Algorithm Engineer
About the position
iOS Algorithm Engineer (CoreMotion / Physics) We are a sports technology startup building an Apple Watch app for sports training. We have a functioning app that records raw accelerometer and gyroscope data. We need a specialist in Signal Processing and CoreMotion to help us tune the algorithm. Engagement Type: Short-Term Contract / Moonlighting Friendly Time Commitment: Estimated ~10–15 hours total. Schedule: Flexible. This work can be completed on evenings or weekends. We focus on the deliverable (the algorithm), not the hours. Location: 100% Remote. The Mission: We are tracking a specific arm movement (throws). We have the raw data logs (CSV). Your job is to analyze this data and provide the logic/code to: Accurately count "Reps" (Throws). Distinguish between a real throw and "Noise" (e.g., dropping the arm, walking, picking up a ball). Handle the drift/noise inherent in MEMS sensors. What We Have: Existing WatchOS app that logs data (User Acceleration, Rotation Rate, Gravity) at 50-100Hz. Dataset of "Clean Throws" vs. "Noise" (CSV format). A lead iOS engineer (Swift) ready to implement your logic. What We Need From You: The Algorithm: You don't need to build the UI. We need the mathematical logic (or Python/Swift function) that takes the raw inputs and returns a "Success" count. Drift Correction: Experience using Complementary Filters, Kalman Filters, or Sensor Fusion to clean up the data. This project focuses on generic signal processing math (physics/vectors) and does not require using proprietary IP from your current employer. We are happy to sign a customized IP agreement to ensure you are protected.
Requirements
• Deep experience with Apple's CoreMotion framework.
• Strong background in Vector Math and Physics.
• Experience with Human Activity Recognition (HAR) or Gesture Recognition.
• Ability to work fast
