Note: The job is a remote job and is open to candidates in USA. Life360 is a mission-driven technology company providing location-sharing, tracking, safety, and family coordination services. The Senior Software Engineer II will develop and scale high-throughput backend services for the AdServer and Exchange platform, enhance real-time bidding and advertising capabilities with AI, and mentor junior engineers while collaborating with architecture and product teams.
Responsibilities
- Build and maintain high-throughput backend services on the AdServer and Exchange platform, contributing to reliability, scalability, and performance targets
- Implement and improve Real-Time Bidding and auction logic, and support integrations with demand and supply partners
- Collaborate with Staff Engineers and architects to execute on platform design decisions and raise concerns where you see gaps
- Own features end-to-end — from design through deployment — with a focus on correctness, observability, and operational health
- Partner with Product on new ad formats and monetization capabilities, translating requirements into solid technical designs
- Contribute to monitoring, incident response, and root cause analysis to improve overall platform reliability
- Use AI tooling (including Claude Code) as a day-to-day collaborator — generating scaffolding, drafting schemas, and accelerating code review
- Mentor junior engineers and contribute to team standards around code quality, testing, and engineering practices
Skills
- Bachelor's degree in Computer Science, Engineering, or a related field
- 5–8 years of backend engineering experience, with strong proficiency in Java and multi-threaded system design
- Experience building or operating high-throughput, low-latency distributed systems in production
- Solid understanding of data consistency, performance trade-offs, and database fundamentals
- Comfort working in cloud-native environments, ideally AWS
- Clear, direct communication — you can explain a technical decision to an engineer or a product manager without losing either of them
- Openness to using agentic workflows and AI-assisted development to reduce cycle time and operational overhead
- Daily use: You use AI coding assistants (we support Claude Code, Cursor, and GitHub Copilot) for real, substantive tasks: analysis, coding, refactoring, testing, navigating codebases, and documentation. Not just research or autocomplete
- 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 — doing more with the same time, taking on problems that would otherwise require a larger team
- 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
- Familiarity with AdTech concepts (RTB, auctions, supply/demand integrations) is a plus
- Experience integrating third-party APIs or partner systems is a plus
