Senior Staff Software Engineer, Host Pricing & Settings

Airbnb is a hospitality technology company that enables hosts to offer stays and experiences to guests worldwide. Airbnb is seeking a Senior Staff Software Engineer to own the technical strategy for modeling, ML serving, and API interfaces across the Host Pricing organization, while architecting unified serving, backfill, evaluation, and domain-contract infrastructure and contributing hands-on code.

Responsibilities:

• Define the architecture and contracts governing how models move from development to production — feature store design, model schema management, online/offline inference consistency, and multi-version support
• 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
• 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 systems BE teams to define artifact handoffs and integration contracts
• Drive milestone planning across the Host Pricing & Settings org, sequencing work to deliver value incrementally
• Mentor engineers through design reviews and hands-on pairing on the hardest infrastructure problems
