As a Staff Data Scientist at Hims & Hers, you are a technical leader and a “force multiplier” for our data organization. You do not just solve the most difficult problems; you identify which problems are worth solving to move the needle for our customers
You will serve as a technical anchor, simplifying ambiguous problems into executable paths for the team
In this role, you will bridge the gap between business strategy and production-ready machine learning
Whether you are building frameworks for growth, optimizing our supply chain, or refining marketing attribution, you will ensure our data products are technically sound, scalable, and built to deliver measurable business results
Architect the 0-to-1 Foundation: Lead the design and implementation of automated ML systems. You know how to balance “doing it right” with “doing it fast,” making pragmatic architectural choices (build vs. buy, simple vs. complex) while rolling up your sleeves to write production code and establish our core ML infrastructure
Translate Business Needs: Turn ambiguous business questions (from customer acquisition to churn dynamics) into concrete technical roadmaps that deliver clear, actionable results
Drive Execution and Reliability: Lead the end-to-end deployment of ML products, ensuring they are not just accurate but robust, maintainable, and fully integrated into our production infrastructure
Connect Technical & Business Goals: Partner across Engineering, Product, and Business to ensure our technical strategy is solving the right business problems and moving our core metrics
Define Technical Standards: Act as a force multiplier by establishing the standards for model development. You will lead design docs and peer reviews that ensure our work is reproducible and integrates with the work of our Data and Analytics Engineering partners
Own the Results: Take accountability for the full model lifecycle, from the initial data design through to the long-term performance and business value of production systems
Mentorship & Coaching: Actively mentor Senior and Mid-level Data Scientists, elevating the technical bar and fostering a culture of continuous learning across the data organization
Benefits
Generous PTO: Take the time you need, when you need it - including generous parental leave
Full healthcare: High-coverage medical, dental & vision coverage for individuals and families
Retirement planning: Take advantage of our 401(k) plan including contribution matching
Work from anywhere: We are a remote-first company, so you can work from anywhere you like in the uS
Robust compensation: We offer competitive salary bands and stock options
Employee discount: Employees can take advantage of product discounts
Utility stipend: A extra $75 each month to cover extra cell phone, internet, or data usage
Spending accounts: Options for additional HSA and FSA plans to help toward healthcare costs
Preferred experience
Leadership & Influence: Proven ability to influence without authority. You can translate complex technical logic into compelling narratives for executive leadership
Systemic Problem Solving: Ability to work on unique issues requiring conceptual thinking and broad impact. You know how to build for long-term scalability while delivering immediate value
Education: BS, MS, or PhD in a quantitative field (Data Science, Statistics, Economics, CS, Applied Math, etc.) or equivalent field expertise
8+ years of experience in Data Science or ML Engineering, with a proven track record of building production systems that deliver measurable business impact
Technical Mastery: High proficiency in Python and SQL. Expert-level experience with the Python data stack (pandas, NumPy, scikit-learn) and at least one major ML framework (such as PyTorch or XGBoost/LightGBM)
Engineering Rigor: Experience with CI/CD, ML Ops, and managing the full lifecycle of models in a cloud-based production environment (AWS or GCP)
If you’re excited about this role, we encourage you to apply—even if you’re not sure if your background or experience is a perfect match
Optimization: Building engines for marketing spend, inventory management, or resource allocation
Customer Behavior & Propensity Modeling: Building predictive models for churn, propensity-to-buy, lead scoring, or lifetime value (LTV) to directly drive targeted marketing and product interventions
Advanced Business ML (Experience in 1-2 of the following):
0-to-1 Execution: Experience taking the very first machine learning models in an organization from exploratory notebooks to reliable, automated production pipelines
Applied Forecasting: Time-series forecasting, anomaly detection, or handling non-stationary data for demand or revenue planning
Causal Inference: Designing robust experiments (e.g., quasi-experiments, difference-in-differences) to measure true business impact beyond standard A/B testing
