Life360 - Lead Data Scientist
Requirements
• 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. • 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. • AI-Native Expectations • Daily use: Running parallel workstreams instead of hand-holding one agent at a time. • Judgment and ownership: Review AI-generated code, analyses, and models as critically as a colleague's pull request. You are accountable for everything you ship, whoever or whatever wrote it. • Velocity: Turn AI fluency into output. We expect you to deliver more production ML, faster, than the same work would take without AI. • Team leadership: Share your AI workflows with the team and raise the AI fluency of the data scientists and engineers around you. • Continuous learning: Keep up with new AI tools and techniques, test them on real team problems, and bring recommendations to the team.
Responsibilities
• 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.
Benefits
