About this role
About the Role Airbnb's Host Pricing & Settings team builds the platform and tools that help hosts run their business — with pricing strategies informed by market intelligence, comparable listings, and demand signals. The north star is a serving infrastructure where training, inference, and evaluation are consistent by design — features from a centralized store, model composition in one place, and backfills available on demand so data scientists and MLEs can evaluate candidates in days, not weeks. As a Senior Staff Software Engineer, you will own the technical strategy for the full Modeling → ML Serving → API interface across the Host Pricing org. You will be hands-on and contribute code while setting architecture direction. What You'll Do
- Review and evolve the ML serving architecture — making tradeoff calls on feature pipeline design, model composition, and API interfaces.
- Write and review code for feature engineering jobs, feature store configurations, and serving service endpoints.
- Partner with Data Science, MLE, MLI and core Pricing & Availability BE teams to define artifact handoffs and integration contracts.
- Lead 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.
- Architect backfill and evaluation infrastructure so the modeling team can simulate production inference over historical data in days, not weeks.
- Establish domain contracts between Modeling and Serving so each team can move independently with clear, enforced interfaces. What We're Looking For
- Strong background designing and implementing scalable ML serving architectures (feature stores, model schema management, online/offline inference consistency, multi-version support).
- Hands-on software engineering skills and ability to write and review production-grade code and ship features to production.
- Experience partnering with Data Science, MLE, MLI and core BE teams to define artifact handoffs and integration contracts.
- Excellent collaboration and communication skills to work across cross-functional teams.
