Zillow – Sr Software Development Engineer, Data Science/Machine Learning

Zillow is looking for software engineers with experience in web-scale distributed systems and machine learning algorithms to join a growing world-class data science and engineering group dedicated to excellence. The group is responsible for cutting-edge analytic products such as the Zestimate®, Rent Zestimate® and housing indices on Zillow’s unparalleled living database of all homes. We utilize modern open-source Big Data technologies such as Apache Hadoop and Spark as the foundation of our ML platform. Building consumer-facing analytic products powering Zillow’s industry-leading online marketplace puts the team and this role at the core of Zillow’s mission to empower the consumer.

What’s in it for you?

• Building cutting-edge, highly parallelized, big data, machine-learning applications (including classification, regression, and neural networks) in the cloud. This role straddles large-scale systems engineering and machine learning, and we are looking for engineers that have solid expertise in both of these areas. Sounds like a Mad Lib of marketing jargon, but we’re serious…that’s what you’ll be building.
• Small team = big impact. Zillow product development is highly decentralized in order to create the small team speed and autonomy of a start-up environment but backed by big company resources.
• Fast-moving, developer-driven organization full of brilliant, ambitious and fast-moving people. Duties
• Design and code highly scalable, machine learning applications processing large volumes of data.
• Work closely with research scientists on prediction models.
• Collaborate with others in crafting and implementing your technical vision.
• Follow agile processes with a focus on delivering production-ready testable code in small iterations.
• Participate in the entire development life cycle, from concept to release.
• Participate in all phases of quality assurance and defect resolution.

Requirements

• Applicants should have a degree (BS+) in a Computer Science or related discipline.
• 2-7 years software development experience with highly scalable systems involving big data and machine learning.
• Extensive experience with C++ or a JVM based language. Strong OO coding skills.
• Experience implementing machine learning or statistical algorithms is desired
• Experience working with very large datasets with data distributed across large data clusters is desired
• Experience with the data analysis languages R and Python.
• Experience with Hadoop and Spark is desired.
• Experience with databases of various vendors and types.
• Experience with modern source control (Git, Hg, SVN).
• Experience with Amazon AWS services (specifically S3, EMR, RDS and EC2).
