The Experimentation & Machine Learning Intelligence team at Life360 sits within the Growth org. We build the platforms and services that let the company learn and personalize at scale. Our work helps every product team ship with confidence and measure real impact for the families who rely on Life360.

We are a product-minded, AI-Native engineering team. AI isn’t just a tool we use - it’s how we work. We’ve redesigned our team workflows around AI, treating it as a first-class collaborator at every stage: ideation, coding, testing, review, and iteration.

Responsibilities

• Design and build high-quality APIs and services for our experimentation platform and recommendation/personalization systems.
• Work with AI as a first-class collaborator, orchestrating agents to create specs, generate code and tests, verify results, and perform reviews.
• Help define and codify AI-Native engineering practices for the team, establishing playbooks the broader org can adopt.
• Build across the backend stack, shipping polished, performant, and reliable experiences to tens of millions of users.
• Collaborate closely with product managers and data teams to turn complex user problems into elegant, scalable engineering solutions.
• Contribute to architectural decisions, code reviews, and a culture of craft and continuous improvement.
• Participate in on-call rotation and incident response.
• Use agentic workflows to dramatically increase the delivery of strong outcomes.
• Mentor team members and contribute to team processes, technical standards, and help evolve the team's AI-native engineering practices.
• Support performance, reliability, and accessibility across the features you own.

Requirements

Technical foundation:

• 6+ years of backend software engineering experience
• Strong proficiency with Java and Spring Boot
• Experience with Apache Kafka or similar distributed streaming platforms
• Solid understanding of distributed systems concepts: consistency, fault tolerance, replication, and data durability
• Comfortable with cloud infrastructure (AWS preferred) and containerized deployments
• Heavy user of agentic workflows, understands research-plan-implement cycle but doesn’t outsource thinking to agents
• At least 1 year of hands-on experience prompting, evaluating, and building with LLMs

What matters most to us:

• Growth mindset
• Collaborative approach
• Ownership mentality
• AI-native working style
• Thoughtful communication
• We believe culture fit and problem-solving ability matter more than checking every technical box.

Nice to Have

• Experience building or operating experimentation, A/B testing platforms or feature-flagging systems
• Experience supporting recommendation, personalization, or ML-serving systems
• Background in stream processing frameworks (Kafka Streams, Flink)
• Experience with schema registries and schema evolution strategies
• Knowledge of Confluent Platform or Confluent Cloud
• Understanding of CI/CD patterns, GitHub Actions, and artifact management (Maven, Nexus)
• Experience with observability tooling (Prometheus, Grafana, DataDog)
• Previous work on ecosystems or integration tooling

AI-Native Expectations

We use AI coding tools as a professional standard on this team. Here's what that means in practice:

• Daily use: You use AI coding assistants for real, substantive tasks: analysis, coding, refactoring, testing, navigating codebases, and documentation.
• Judgment and ownership: AI-generated code gets the same review you'd give any PR. You are accountable for everything you ship.
• Velocity: We expect senior engineers who use AI well to operate with meaningful leverage.
• Team leadership: You share what works. You automate prompting strategies that others can build on and help teammates earlier in their AI workflow adoption get up to speed.
• Continuous learning: The tooling is changing fast. You stay current and bring recommendations to the team when something would meaningfully improve how we work.

We Offer

• Competitive pay and benefits.
• Medical, dental, vision, life, and disability insurance plans (100% paid for US employees). 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.
