Note: The job is a remote job and is open to candidates in USA. Life360 is a company focused on keeping families connected through innovative technology. They are seeking a Senior Software Engineer II who will play a crucial role in building the experimentation and machine learning infrastructure, utilizing AI tools to enhance development processes and improve user experiences.
Responsibilities
- Design and build high-quality APIs and services for our experimentation platform and recommendation/personalization systems — experiences that are reliable, performant, and genuinely useful to product teams and members
- Work with AI (Claude Code) as a first-class collaborator — your primary workflow involves 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 as needed — 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 — moving faster without sacrificing quality
- 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
Skills
- 6+ years of backend software engineering experience
- Strong proficiency with Java and Spring Boot (this is our primary stack)
- 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
- Growth mindset - You structure problems precisely, you learn quickly, you can show interest outside 'your lane', and you are always happy to try something new
- Collaborative approach - You communicate clearly, work well across teams, and value diverse perspectives
- Ownership mentality - You take responsibility for your work from design through production and beyond
- AI-native working style - You use AI tooling (Claude Code or equivalent) as a genuine development partner: delegating discrete tasks, reviewing outputs critically, and running parallel workstreams rather than hand-holding one agent at a time
- Thoughtful communication - You can explain technical tradeoffs and articulate ideas effectively
- Experience building or operating experimentation, A/B testing platforms or feature-flagging systems
- Experience supporting recommendation, personalization, or ML-serving systems (feature stores, online/offline pipelines, low-latency model serving)
- 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
