Senior Staff Software Engineer, Host Pricing & Settings

ABOUT THE ROLE As a Senior Staff Software Engineer on the Host Pricing & Settings team at Airbnb, you will play a key role in building the platform and tools that help hosts run their business. You will be responsible for defining the technical strategy for the full Modeling → ML Serving → API interface across the Host Pricing org, and will own the architecture and contracts governing how models move from development to production. WHAT YOU'LL DO As a senior technical individual contributor, you will be hands-on and contribute code to the team. Your responsibilities will include: - Defining the architecture and contracts governing how models move from development to production, including feature store design, model schema management, online/offline inference consistency, and multi-version support. - Leading the buildout of a unified serving stack that eliminates per-model one-off implementations and gives data scientists a turnkey path from training to production. - Architecting backfill and evaluation infrastructure so the modeling team can simulate production inference over historical data in days, not weeks. - Establishing domain contracts between Modeling and Serving so each team can move independently with clear, enforced interfaces. - Reviewing and evolving the ML serving architecture, making tradeoff calls on feature pipeline design, model composition, and API interfaces. - Writing and reviewing code for feature engineering jobs, feature store configurations, and serving service endpoints. - Partnering with Data Science, MLE, MLI and core Pricing & Availability systems BE teams to define artifact handoffs and integration contracts. - Driving milestone planning across the Host Pricing & Settings org, sequencing work to deliver value incrementally. - Mentoring engineers through design reviews and hands-on pairing on the hardest infrastructure problems. WHAT YOU'LL NEED To be successful in this role, you will need: - 12+ years in backend or platform engineering, with substantial experience building production ML systems or data-intensive infrastructure. - Strong programming skills in Java, Kotlin, Scala, and/or Python. - Deep understanding of ML systems design: feature stores, training/serving consistency, model versioning, and online/offline inference pipelines. - Experience with high-scale batch and real-time data pipelines (Spark, Airflow, Kafka, or equivalent), including point-in-time correctness for backfills. - Expertise with architectural patterns of large, high-scale applications — well-designed APIs, efficient data contracts, multi-tenant serving infrastructure. - Proven ability to lead cross-team technical initiatives spanning ML and platform engineering.
