Description de poste
We believe technology should strengthen relationships and make daily coordination less complicated. Everything we create is designed to lighten the mental load, reduce conflict, and support families through big and small moments.
If you want your work to make a real difference in the daily lives of parents and kids, In Tandem is the place where your impact will truly matter.
As our Product Data Scientist, you'll bring rigorous behavior analysis and predictive modeling to how our apps understand and serve our members — partnering closely with Product and Finance to turn millions of family interactions into models that shape both the product roadmap and the business strategy across OurFamilyWizard, Cozi, and FamilyWall.
Why Join?
We’re redefining family technology.
In Tandem brings together a growing portfolio of trusted tools that support families, and the professionals who guide them, through the moments that matter most. We bring clarity to chaos and stability to daily family life, helping parents feel less stressed so kids can have healthier childhoods.
Scale meets startup energy.
With more than 20 years of impact and a strong market presence, we’re entering a bold new chapter of growth. We have the foundation, the momentum, and the ambition to go further: expanding our reach, deepening our impact, and elevating the tools families and professionals rely on every day.
Purpose-driven. Performance-focused. People-first.
Our culture is rooted in accountability, curiosity, and collaboration. We value diverse perspectives, thoughtful problem-solving, and teammates who care deeply about building something that matters. We believe technology can champion deeper connections within families, strengthen bonds, and improve communication. We're building solutions that foster connection, organization, and peace-of-mind throughout key stages and milestones of family life.
Description
At In Tandem, we build technology that helps families manage everyday routines and navigate life’s biggest transitions. Through our four brands—OurFamilyWizard, Cozi, FamilyWall, and Custody Navigator—we help families stay organized, communicate well, and foster healthy childhoods.We believe technology should strengthen relationships and make daily coordination less complicated. Everything we create is designed to lighten the mental load, reduce conflict, and support families through big and small moments.

What you will accomplish:
Smart, personalized in-app experiences- Ship the models that power personalized in-app experiences — predicting what each member is likely to want next based on real-time behavior, family context, and engagement history.
- Detect meaningful patterns in product usage data — communication, scheduling, and activity signals — and build the models that turn those patterns into in-app suggestions, alerts, and guidance for families.
- Help replace fixed-placement UI logic with algorithmic decisioning that adapts every time someone opens the app.
- Build the churn, retention, and activation models that help Product understand which behaviors predict long-term value and which interventions are worth shipping.
- Develop predictive segmentation, propensity, and uplift models, refreshed continuously through automated pipelines so the rest of the business is always acting on current signal.
- Partner with Finance on cohort-level subscriber and revenue forecasting, LTV by acquisition source, and sensitivity analysis on the assumptions that matter most.
- Build pricing, promo, and refund-risk models that quantify the financial impact of monetization decisions before we ship them.
- Train, deploy, and monitor models in Databricks and AWS, using Claude Code as your primary engineering interface.
- When agentic delivery makes sense, wrap models in managed agents that surface predictions into the workflows stakeholders already use.
- Move the team from "what happened" to "what would happen if" — uplift modeling, geo-tests, and A/B analysis grounded in proper causal framing.
Who you are:
- A modeler who thinks in patterns, hypotheses, and tests, and who owns problems end to end — from question framing through SQL, feature pipelines, modeling, serving, and stakeholder communication. You ship models real decisions depend on, not just notebooks and decks.
- Pragmatic about ML — you know when a model is worth building and when a heuristic does the job, and you translate a CFO's question and a PM's question with the same fluency.
- AI-first in how you build. Modern AI tooling — Claude Code, agent SDKs, coding agents — is part of your craft, and you operate at higher leverage because of it.
- Motivated by work that matters. Families rely on these products during real moments in their lives.
What you bring:
- 5+ years shipping predictive models in production, ideally across personalization, behavioral prediction, lifecycle ML, or subscription forecasting.
- Strong Python and SQL. Hands-on experience with Databricks and AWS.
- Demonstrated success with subscription or consumer-app metrics — LTV, churn, retention, activation, forecasting.
- Solid grasp of experimentation and causal methods (A/B, DiD, uplift, geo-tests, or similar).
- Production rigor — feature pipelines, model monitoring, retraining cadence.
