Software Development Engineer

About the team

The Agentic AI team at Zillow is transforming the real estate industry by helping millions of people use AI assistants to find their next home. We are building always-on AI experiences that combine personalized user insights with Zillow's deep real estate knowledge. The Memory and Evals team builds foundational capabilities that make these experiences more useful, trustworthy, and scalable — including user memory and context systems, evaluation frameworks, tracing, observability tools, and feedback loops that help teams understand agent behavior, identify failure modes, and continuously improve. As part of this lean, customer-focused team, you will partner with applied scientists, software engineers, machine learning engineers, and product leaders to evolve Zillow's next-generation AI platform.

About the role

We are seeking a collaborative, product-minded backend engineer with strong agentic AI fundamentals and a passion for building reliable, scalable systems that power AI applications. In this role, you will design, build, and scale evaluation frameworks for Zillow's agentic AI experiences; build tracing, observability, and quality measurement systems for production AI agents; create platform infrastructure that enables domain teams across Zillow to build on top of the evaluation platform; partner with applied scientists and machine learning engineers; and help evolve how Zillow measures AI quality, reliability, and trustworthiness.

You will get to:

- Architect, develop, and maintain scalable, secure, and highly available backend services and APIs that power Zillow applications and platforms.

- Lead design and implementation of backend solutions that optimize performance, reliability, and observability for large-scale, distributed systems running in containerized and cloud environments.

- Collaborate with product, data, and machine learning teams to translate requirements into robust technical designs and end-to-end solutions.

- Implement and uphold engineering best practices, including automated testing, code review, continuous integration and delivery, instrumentation, and operational runbooks.

- Troubleshoot and resolve complex production issues, conducting root cause analysis and driving systemic improvements.

- Mentor other engineers through code and design reviews, pairing, and knowledge sharing.

This role has been categorized as a teleworker position. Teleworkers 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. Employees may live anywhere in Mexico, with availability to travel to Mexico City, as we recommend attendance at occasional office events.

In addition to a competitive base salary and benefits, this position is also eligible for equity awards based on factors such as experience, performance and location.

Who you are

- Bachelor’s degree in Computer Science, Computer Engineering, or a related field. - 8+ years of experience in software engineering with a focus on backend or server-side development for scalable, high-availability systems. - Experience designing, building, and operating RESTful or gRPC services and APIs in one or more modern programming languages (for example, Java, C#, Python, Go, or similar) in production environments. - Hands-on experience with cloud platforms (such as AWS, GCP, or Azure) and containerization/orchestration technologies (such as Docker and Kubernetes) for deploying and operating services at scale. - Experience working with both relational and non-relational data stores and messaging/streaming technologies to support high-volume data processing and integration. - Demonstrated experience collaborating in cross-functional, agile teams to deliver production software, including participation in planning, estimation, and release practices. - Or an equivalent combination of education and experience.
