Healthcare is broken at the first step: patients can't find the right care, understand what it costs, or access the medications they need. Mochi Health is fixing this.
We're building an AI-driven marketplace that makes healthcare discoverable—connecting patients to the right providers, transparent pharmacy pricing, and affordable medications. Over the past few years, we've grown rapidly by combining clinical expertise with technology that actually works for real people, not just hospital systems.
Our platform does what legacy healthcare can't: it gives patients transparent pricing before they pay, personalized medication management that follows them across providers, and long-term access to their own medical records. We're proving that healthcare can be more affordable, more human, and far more intuitive than what exists today.
Join a team that's rebuilding healthcare from the patient up. At Mochi Health, you'll work alongside people who value bold thinking, inclusive collaboration, and getting meaningful work into the world. If you want to do the most impactful work of your career, this is where to do it.

About The Role
We’re a telehealth company helping people lose weight at scale. Experimentation is central to our growth and patient experience—we need to know what truly works, what doesn’t, and why. We’re looking for a Senior Data Scientist who thrives on designing, running, and interpreting experiments across product, pharmacy, and design. You’ll work side-by-side with clinicians, designers, and engineers to push forward a culture of evidence-based decision-making.
This role is ideal for someone who wants to set the standard for how experiments are run at Mochi Health—bringing statistical rigor, practical intuition, and a deep sense of ownership.
What You’ll Do
- Own the design and execution of experiments (A/B tests, quasi-experiments) across pharmacy, design, and product flows
- Partner with design and pharmacy teams to ideate, prioritize, and scope impactful experiments
- Build frameworks and tools to standardize experimentation and causal inference across teams
- Ensure experiment integrity—sample sizing, randomization, stopping rules, multiple-testing corrections
- Move beyond binary “did it win?” to nuanced insights: heterogeneous treatment effects, and trade-offs
- Automate experiment reporting and integrate results into dashboards / internal tools
- Mentor teammates and set best practices for experimentation at the company
Who You Are
- Bachelor’s or Master’s in a quantitative field (e.g., Statistics, Engineering, Economics)
- Bachelor’s, Master’s, or PhD in a quantitative field (e.g., Statistics, Computer Science, Economics)
- 4+ years of industry experience in applied experimentation (growth or product preferred)
- Deep expertise in causal inference methods (A/B testing, DiD, matching, Bayesian methods)
- Strong Python and SQL skills; capable of building reusable frameworks, not just one-off analyses
- Clear communicator who can translate complex experimental results into actionable recommendations
- Comfortable with ambiguity, fast iteration, and working across very different teams (Example: pharmacy, design, ops)
- Motivated by impact - you want your work to directly shape patient care and company growth
