Work on the cutting edge of AI, on your own schedule, and get paid for the biomedical signal processing expertise you already have.

The AI systems everyone is talking about are trained and tested by real experts. The teams building them need biomedical signal processing professionals who can create realistic, difficult problems, judge how well an AI handles them, write the answer a specialist would give, and explain exactly where the AI falls short. Your judgment becomes part of how the next generation of AI models works. This is that work, done remotely around your current job.

What you'll do

- Create difficult tasks using real physiological signals and time-series data
- Design tasks involving preprocessing and filtering of biomedical signals
- Prepare reproducible reference answers using Python, MATLAB or comparable scientific software
- Check your methods, make sure another person can replicate the work, and deliver it against the project specifications

Why this is worth your time
- Build real AI skills on top of your current job while earning the equivalent of $60–$120 an hour
- Work on AI systems that learn from biomedical signals, building the problems and reference solutions used to test and improve them




- Build practical experience applying signal processing and ML judgment to AI training tasks and clear technical feedback
- Fully remote and flexible, no fixed shifts, no commute

Who this is for

- Experience competing in the PhysioNet/CinC Challenge, or in a similar competition in biomedical signal processing or scientific ML
- Demonstrate your own substantial technical contribution publicly, for example through a team result, a paper, a repository, a technical report or a substantial code contribution
- Hands-on experience with clinical time-series data such as ECG and EEG, plus PPG, EMG, polysomnography, respiratory signals and related data; proficiency in Python or MATLAB, or in another scientific computing language; fluent English
- No experience in AI training work needed. You bring the expertise; we bring the training on the tools.

Pay and details

- $60–$120 per hour equivalent; pay is per accepted task, as an independent contractor
- Under 20 hours a week, you choose when; fully remote, India

How to apply

- Apply on OpenTrain (upload your CV).
- Complete a short application on the hiring platform.
- If shortlisted, take a short AI interview.
