Machine Learning Engineer

About The Team

As the engine behind Zillow Group's mission to build a seamless digital real estate marketplace, the Shopping AI team is fundamentally redefining how millions of people discover and shop for homes. Our team of engineers and scientists builds and owns the production machine learning systems that power Zillow's core user experience, including personalized ranking & recommendations, semantic search, autocomplete, and display optimization. Working closely with product and design, we apply the latest advancements in AI to solve unique, large-scale challenges. As we look forward, we are tackling the next generation of questions, including how generative AI can unlock intuitive, personalized experiences for every home shopper.

About The Role

You Will Get To:

• Design, build, and ship production new machine learning models that power core product features on the Zillow app, website, and email/push notifications.
• Help re-architect our core home ranking and recommendation systems to support advanced neural networks and dramatically accelerate the pace of experimentation across surfaces.
• Own the full lifecycle of your models, from offline experimentation and prototyping with massive datasets to online deployment, A/B testing, and performance monitoring.
• Pioneer the application of cutting-edge deep learning and large language models (LLMs) to improve our home shopping experience.
• Develop new AI components that optimize how we display and when we recommend homes, ensuring we connect shoppers with the right content on the right properties at the right time.
• Collaborate in a cross-functional group of engineers, applied scientists, product managers, and designers to define, execute, and iterate on the team's strategic roadmap.
• Contribute to the team's engineering excellence by improving our machine learning infrastructure, development standards, and shared tooling.

This role has been categorized as a Remote position. “Remote” employees do not have a permanent corporate office workplace and, instead, work from a physical location of their choice, which must be identified to the Company. U.S. employees may live in any of the 50 United States, with limited exceptions.

Who you are

Must Have:

• 1-3 years of experience in developing applications in search, personalized ranking, or recommender systems
• Experience developing and deploying ML models that scale to high-traffic, latency sensitive customer-facing services (100s of millions of requests per day)
• Strong programming skills in a high-level language such as Python or Java
• Familiarity with common machine learning libraries like PyTorch, TensorFlow, Catboost, scikit-learn and huggingface (repository)
• Expertise with large scale distributed data processing systems such as Hive, Spark, Airflow, or Databricks
• Experience owning the full lifecycle of customer facing machine learning models, from offline experimentation and prototyping to online deployment, A/B testing, and performance monitoring

Preferred:

• A Master's degree + 2 yrs or BS with a minimum of 4 yrs of experience (preferably in large consumer tech companies)
• Prior experience or high level of curiosity with generative AI and excitement to collaborate on what they’ve learned!
