[Hiring] Lead Data Scientist @Life360

Role Description

As a Lead Data Scientist, you will own the path from revenue opportunity to production ML for Direct Revenue, the business unit responsible for growing active users, subscriptions, revenue-generating transactions, and in-app advertising across Life360's more than 100 million monthly active users. You will find the opportunities, size them, agree on priorities with business leads, and ship the models alongside the team's data scientists and engineers.

This role matters now because the team is expanding to cover consumer-facing ads, including recommendations and personalization, and needs a senior scientist who pairs a deep understanding of the problem with the ability to put models into production. In your first year, you will help the team scale the amount of production ML it delivers and help set the team's roadmap with the data science lead and the product manager.

What You’ll Do

• Conduct deep investigations into revenue-generating options and the data behind them, and use them to size, scope, and measure product changes in Databricks.
• Design, build, deploy, and operate production ML systems, from batch inference to online services to online learning models, using the team's feature store and model registry, for personalization, experimentation, and automation use cases.
• Partner with Product, Mobile Engineering, Cloud Engineering, Data Engineering, and MLOps to integrate these systems into user-facing features.
• Set up monitoring for new ML-based features so their performance and business impact are measured.
• Implement lineage tracking for data, code, and model artifacts to keep the ML lifecycle compliant, reproducible, and secure.
• Improve the data ecosystem with Data Engineering, including the pipelines that feed experimentation and ML.
• Mentor other data scientists and define best practices for advanced analytics and ML system development.
• Use Claude Code and other AI tools across data discovery, modeling, and experiment evaluation.

Qualifications

• Education: advanced degree in a field that relies on sophisticated statistical analysis or equivalent industry experience.
• Professional Experience: 6+ years of experience scoping, building, and analyzing ML-powered systems, including models you have shipped to production.
• Programming Proficiency: Significant experience with Python and scikit-learn, PySpark, and causal inference programming languages, including familiarity with software engineering best practices (testing, modularization, version control, etc.).
• Causal Inference: Technical training and professional experience applying modern causal inference and causal analysis techniques.
• Instrumentation and Measurement: Significant experience working with found data, guiding instrumentation to generate new data, and implementing data transformations to support complex analyses and ML system development.
• Experimentation: Hands-on experience setting up experiments in the consumer technology space, including experiment design, monitoring, and analysis of results.
• Consumer Product Experience: Experience building ML or running experiments at a consumer (B2C) technology company, ideally on revenue work such as subscriptions, transactions, or ads.
• Communication and Leadership: Strong communication and project leadership skills, with the ability to influence cross-functional teams.
• Problem Solving: Strong capability to solve ambiguous problems in a structured, hypothesis-driven, data-supported way.
• Generative AI & LLMs: Prior experience leveraging LLMs in advanced data processing and analysis workflows.

Preferred Qualifications

• Digital Advertising: Experience with modern digital advertising, including ad tech infrastructure.
• Feeds and Ranking: Experience with ranking and grouping algorithms for content feeds.
• Advanced Tooling: Experience contributing to and managing production feature stores and ML model registries.
• Revenue Partnership: Experience working with product line GMs, including familiarity with revenue reporting and forecasting analyses.
• Subscription Products: Experience in subscription-based products, lifecycle marketing, or user acquisition.
• Geospatial: Experience with geospatial data and mobile location-based services.

Benefits

• Medical, dental, vision, life and disability insurance plans (100% paid for US employees). We offer life and disability as well as supplemental plans for medical and dental for Canadian employees.
• 401(k) plan with company matching program in the US and RRSP with DPSP plan for Canadian employees.
