• Raise engineering standards and address systemic gaps in quality, reliability, observability, release safety, and developer productivity
• Remain hands-on across architecture, critical implementation, design reviews, debugging, launches, and production operations
• Participate in in-person Nextdoor events such as trainings, off-sites, volunteer days, and team building exercises
• Build in-person relationships with team members and contribute to Nextdoor’s company culture

What You’ll Bring To The Team

• Exceptional system design skills and a proven record of building scalable, reliable, high-performance distributed systems
• Deep experience building advertising platforms, including a strong understanding of large-scale native ad-serving systems
• Expert-level proficiency in at least one of the languages: Java, Kotlin, or Python
• Extensive experience building large-scale, real-time data pipelines using Apache Kafka, Apache Flink, or Kafka Streams
• A strong record of mentoring senior engineers, developing technical leaders, and raising the engineering bar across teams
• Experience using AI-powered development workflows to improve engineering productivity, quality, and delivery speed

• Experience developing or productionizing machine-learning models in partnership with ML engineers and data scientists
