Sr. Systems Engineer

About the team

The Infrastructure Systems Engineering team transforms complex infrastructure systems into simple, scalable, and highly available platforms that accelerate developer velocity and business outcomes. We focus on building resilient, software-driven solutions that power core compute, storage, and foundational services like DNS, OS imaging, and certificate management across both Windows and Linux environments. We are also a high-performing operations team, responsible for managing the scaling, performance, security, and lifecycle of critical infrastructure across the company. As our platform matures, we’re increasingly focused on optimizing operational processes and streamlining infrastructure management—freeing up time and capacity to build self-service platforms that abstract complexity for our internal customers and enable high-velocity development. We apply software engineering principles to the infrastructure domain—crafting modular Infrastructure-as-Code, configuration management pipelines, and self-service capabilities that abstract cloud complexity for internal engineering and non-technical customers. You’ll work closely with product engineering, networking, SRE, developer experience, and container platform teams to deliver foundational capabilities that empower Zillow’s internal teams and directly impact customer-facing experiences. We are a geographically distributed, multidisciplinary team that values ownership, transparency, and impact. We participate in a regular on-call rotation to ensure reliability and responsiveness across our systems.

About the role

As a Senior Systems Engineer, you’ll play a pivotal role in shaping Zillow’s next-generation infrastructure platform. This is a highly collaborative, high-impact role for an engineer who thrives on designing, automating, and delivering reliable systems at national scale in a microservices-based, product engineering environment.

You’ll help scale and operate infrastructure that supports thousands of services and applications across Zillow Group, while contributing to our long-term strategy of transitioning from traditional operations to platform-based, productized infrastructure services. This evolution empowers teams across the company to manage their infrastructure needs without deep systems knowledge, increasing velocity and reliability.

This is not a maintenance role. You’ll shape the future of infrastructure at Zillow, working on high-visibility, high-impact initiatives that simplify and scale infrastructure delivery across the company. You’ll introduce new technologies, define best practices, and directly impact developer experience and operational excellence.

If you are passionate about building elegant infrastructure solutions, love to drive change through code, and want to leave your mark on a dynamic and growing engineering organization—we want to hear from you.

In this role, you will

Design and build foundational infrastructure services using automation-first, software-defined approaches.

Lead development of reusable infrastructure software that abstracts and simplifies AWS provisioning and lifecycle management.

Contribute to re-platforming legacy infrastructure toward modern, cloud-native solutions.

Drive operational efficiency through system automation, lifecycle management, monitoring, and configuration management.

Own core infrastructure technologies, including OS provisioning, DNS, certificate management, AMIs, and network security groups across Windows and Linux.

Be a key contributor to incident response, change management, and roadmap planning.

Collaborate cross-functionally with engineering and platform teams as your customers to identify infrastructure bottlenecks and develop scalable solutions.

Participate in the team’s on-call rotation and continuously improve service reliability and observability.
