WHOOP is an advanced health and fitness wearable, on a mission to unlock human performance. WHOOP empowers its members to improve their health and perform at a higher level by providing a deep understanding of their bodies and daily lives.
As a Staff Machine Learning Engineer on our Training team, you will develop algorithmic features and metrics that capture aspects of daily movement, exercise, and training. You'll integrate diverse data sources—including WHOOP sensor data and gold-standard reference datasets—while grounding your work in clinical theory and scientific literature.
You’ll work cross-functionally with data scientists, MLOps engineers, and software developers to design, train, deploy, and maintain machine learning algorithms that power training features. You'll also partner with product managers to identify opportunities for delivering novel, data-driven insights to WHOOP members.
RESPONSIBILITIES:
- Design, train, and optimize machine learning algorithms for movement, exercise and training applications across diverse backend platforms
- Collaborate closely with data scientists, ML Ops and software engineering teams to ensure reliable deployment, observability, and robust integration with the WHOOP ecosystem
- Contribute to technical roadmap development and architectural decision-making and strategy across the data science and research department
- Collaborate with product managers to design impactful, member-facing features
- Work closely with a team of data scientists in developing algorithms that power member-facing features
- Work with Data Engineers to improve data pipelining, tooling for machine learning, and systems for quality and validation
- Mentor other data scientists on the team, by providing actionable feedback for more junior data scientists on technical areas of growth
- Periodically serve as the on-call data scientist to respond in real time to incidents affecting production services
QUALIFICATIONS:
- Bachelor's Degree in Mathematics, Statistics, Computer Science, or a related field
- 7+ years of ML engineering, applied research, or a similar role
- 4+ years experience applying advanced mathematical and statistical techniques
- Experience deploying and maintaining production ML systems on cloud platforms (e.g., Kubernetes, AWS, GCP)
- Familiarity with MLOps best practices and the ability to collaborate effectively with infrastructure teams on Docker, CI/CD workflows, model versioning, and observability tools
- Experience working with time series data, preferably with wearable data applications
- Proficiency in scientific Python and SQL
- Excellent verbal and written communication skills
