Responsibilities

As a Staff Data Scientist on the Ads team, you'll own deep analysis of technical problems in ads delivery and translate that analysis into algorithmic solutions - then work directly with engineers to implement, deploy, and operate what you build. This role sits inside the Ads business unit, one of Life360's core revenue lines, and you'll partner closely with other Data Scientists and engineers to turn data and models into systems that increase the scale and efficacy of the ads served across our infrastructure. We're hiring for this role now because the team is scaling ads-optimization models beyond initial pilots and needs a senior specialist to own that transition end to end. In your first year, success looks like taking at least one ads-optimization model from prototype to production and measurably improving a delivery metric - such as bid efficiency or inference latency - at scale.

Key Responsibilities

• Partner with Product, Data Science, Cloud Engineering, and Data Engineering to design, develop, and deploy machine learning and optimization solutions.
• Train, deploy, and scale machine learning models as high-availability microservices or batch processing workflows, working with infrastructure and backend engineers to integrate model outputs directly into our ads systems.
• Establish unified logging, alerting, and monitoring solutions to track model inference performance, system latency, resource utilization, data drift, and concept drift.
• Implement robust lineage tracking for data, code, and algorithmic artifacts to ensure compliance, reproducibility, and security across the entire development and operational lifecycle.
• Work with data engineering to improve the data ecosystem, ensuring robust, scalable pipelines for experimentation and ML.
• Mentor other Data Scientists and help define best practices and technical architectures for machine learning engineering and scalable ML service ops.
• Use agentic AI tools (Claude Code or equivalent) as a core part of your daily workflow - delegating implementation tasks, running parallel workstreams, and critically reviewing AI-generated code and analysis before it ships.
• Handle on-call rotation and address live production incidents.

Requirements

Required

• Education: Advanced degree in a quantitative field-or equivalent industry experience.
• Professional Experience: 8+ years of experience analyzing, implementing, and operating machine learning and/or optimization systems.
• Programming Mastery: Strong proficiency in Python with deep familiarity with software engineering best practices (testing, modularization, version control, etc.).
• MLOps and Datastore Tooling: Familiarity with specialized ML lifecycle and data processing tools and platforms such as MLflow, Kubeflow, SparkML, Synapse ML, SQL, Spark/PySpark, dbt, and Airflow.
• Cloud Foundations: Practical experience operating within a major cloud ecosystem-e.g., AWS, GCP, Databricks-with a clear grasp of cloud networking, security, and storage tiers.
• Strong communication and project leadership skills, with the ability to influence cross-functional teams.

Nice to Have

• Hands-on experience formulating and solving optimization problems (e.g., linear programming, mixed-integer programming) for advertising use cases such as budget allocation, bid optimization, or audience targeting.

We Offer

• Competitive pay and benefits.
• Medical, dental, vision, life, and disability insurance plans (100% paid for US employees). We offer 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.
• Employee Assistance Program (EAP) for mental wellness.
• Flexible PTO and 12 company-wide days off throughout the year.
• Learning & Development programs.
• Equipment, tools, and reimbursement support for a productive remote environment.
• Free Life360 Platinum Membership for your preferred circle.
