Senior Software Engineer, Assistant Engineering

Airbnb was born in 2007 when two hosts welcomed three guests to their San Francisco home, and has since grown to over 5 million hosts who have welcomed over 2 billion guest arrivals in almost every country across the globe. Every day, hosts offer unique stays and experiences that make it possible for guests to connect with communities in a more authentic way.

Artificial Intelligence is at the heart of Airbnb’s product strategy. The Conversational Product team within Assistant Engineering is responsible for building and scaling Airbnb’s AI Assistant experience, expanding it beyond customer support to empower product domains across Airbnb.

Within the Conversational Product team, the AI Assistant Product Evaluation team builds the evaluation systems, data foundations, and observability tools that help Airbnb develop reliable, high-quality agentic AI products. Our work enables teams to measure AI product quality, understand model and agent behavior, identify regressions, and accelerate the feedback loop between model development and product iteration.

As a Senior Software Engineer on the AI Assistant Product Evaluation team, you will design and build scalable data systems and evaluation platforms for Airbnb’s agentic AI products. You will work at the intersection of backend engineering, data systems, AI evaluation, and product quality.

In this role, you will help define how Airbnb measures, monitors, and improves the quality of agentic AI products at scale. You will build data-rich systems that transform product interactions, model outputs, human feedback, and evaluation results into reliable signals for product and model development. Your work will help teams move faster with greater confidence by making AI quality measurable, debuggable, and actionable across the development lifecycle.

You will also partner closely with modeling teams, product managers, data scientists, and operations teams to turn ambiguous AI evaluation needs into robust systems that help Airbnb ship trustworthy AI experiences.

• Design and productionize scalable data systems that support AI evaluation, metric computation, observability, and feedback loops for agentic AI products.

• Build data models, schemas, and processing pipelines for agentic AI interactions, supporting reliable logging, retrieval, metric computation, and long-term evaluation dataset management.

• Work closely with Core Modeling engineers to understand pain points in the LLM evaluation process, and develop LLM-as-a-judge solutions and data pipelines to address metric-related challenges in a scalable and efficient way.

• Collaborate with machine learning infrastructure engineering teams to evolve how we build and test evaluation framework for Airbnb Conversational AI products.

• Lead all phases of software development including architecture design, implementation and testing.

• Work collaboratively with cross-functional partners including product managers, operations and data scientists, identify opportunities for business impact, understand and prioritize requirements for machine learning systems and data pipelines, drive engineering decisions and quantify impact.

• Foster a culture of engineering excellence by supporting teammates in writing high-quality code, ensuring operational reliability, and sharing knowledge across the team.

• 5+ years of industry experience as a software engineer, backend engineer, platform engineer, or data-focused software engineer building production systems.

• BS, MS, or PhD in Computer
