About Mira
Mira is a San Francisco-based hormonal health company that provides integrative care and hormonal testing to over 300,000 customers. In 2023, we were recognized by Inc. 5000 as America's fastest-growing femtech company.
Mira’s breakthrough innovation was creating the market’s only FDA-compliant at-home hormone monitor with quantitative testing technology. From the beginning, our mission has been to make hormone data accessible and meaningful - so women can understand their bodies and make confident health decisions at every stage of life, from cycle health and family planning to hormonal imbalances and the menopause transition.
We are committed to improving real health outcomes through personalized insights, cutting-edge technology, and science-backed data - turning hormone information into practical guidance for everyday wellbeing.
About The Position
Mira is building the future of women's hormonal health through quantitative hormone tracking technology. We're seeking an exceptional Data Scientist to be the founding member of our data science function. This is a unique opportunity to define and build the algorithmic foundation that will help millions of women better understand their reproductive health.
As our first Data Scientist, you will own the entire research agenda - from defining what to measure and why, to building production-ready algorithms that interpret complex hormonal data across diverse populations. You'll work at the intersection of reproductive biology, machine learning, and regulated medical device development, translating cutting-edge science into features that ship in our consumer product.
This role reports to the Head of R&D and will eventually grow into leading a data science team as we scale.

Requirements
Must-have:
- Strong Python and data science skills; SQL preferred.
- Experience with longitudinal, time-series, behavioral, health, wearable, physiological, or biomarker data.
- Experience using model interpretability and explainability methods: SHAP, LIME, etc.
- Experience in consumer health, digital health, wearables, diagnostics, medical devices, SaMD, or IVD.
- Strong model validation judgment, including handling missing data, avoiding leakage, testing robustness, and evaluating performance across user segments.
- Ability to translate data into user-facing product features, metrics, recommendations, or algorithms.
- Experience building models, scores, or analytical frameworks that influenced product, clinical, or business decisions.
- Strong communication skills with both technical and non-technical stakeholders.
- High ownership, startup speed, and comfort working with ambiguity.
- Good scientific judgment; able to distinguish product insights from clinical or marketing claims.

- Advanced degree in a quantitative, biomedical, physics, or health-related field.
- Experience with Bayesian statistics, signal processing, causal inference, survival analysis, or longitudinal modeling.
- Experience moving ML or algorithmic features toward production.
- Familiarity with clinical validation, regulatory documentation, claim substantiation, or peer-reviewed research.
Responsibilities
- Build and improve biometrics, algorithms, and data-driven insights for the Mira App.
- Analyze hormone, cycle, app behavior, and user outcome data to identify patterns and product opportunities.
- Develop and validate models for ovulation prediction, cycle modeling, hormone interpretation, and personalized recommendations.
- Partner with Product, Design, Engineering, R&D, and the Real-World Evidence Scientist to translate data into app features and evidence-backed insights.
- Support RWE and clinical research projects with data extraction, exploratory analysis, modeling, and validation.
- Define model-performance and validation frameworks, including uncertainty, subgroup performance, missing data, and edge cases.
- Improve data quality by identifying instrumentation gaps and recommending better data capture in the app.
- Document model logic, assumptions, limitations, and appropriate use cases clearly for technical and non-technical teams.
- Work with Engineering to move prototypes toward production-ready app features or data pipelines.
