Job Description

Target as a tech company? Absolutely. We’re the behind-the-scenes powerhouse that fuels Target’s passion and commitment to cutting-edge innovation. We anchor every aspect of being America’s most loved retailer with cutting-edge technology, and the smartest engineers in retail technology! Site Reliability Engineering (SRE) at Target is an engineering discipline that combines software and systems engineering to build and run large-scale, massively distributed, and fault-tolerant systems.

As a Lead Engineer in SRE, you are someone who has demonstrated experience building highly scalable platforms and fault-tolerant systems across a range of technologies, including Linux, Apache, MongoDB, Python, Oracle RDBMS, Redis, Postgres, and Hadoop. We use a combination of Google Computing Platform and our own server farms operating out of Target Data Centers, and therefore, experience managing application stacks in a Hybrid cloud is preferred. You are a thought leader and mentor for internal and external technical talent and actively contribute to the external technical community.

Job Summary:

As a member of the SRE team, you will contribute to technical architecture, product prioritization, scalable automation, capacity planning, adoption of supporting technologies, and all other aspects of maintaining a world-class cloud-based service. You will work closely with software engineering teams developing infrastructure and applications and focus on driving scalability, stability, reliability, operability of services, and security for Omnichannel retail experiences.

Site Reliability Engineers are hybrid systems and software engineers who are responsible and take ownership for reliability, scalability, automation, and other issues related to the availability of Target’s e-commerce/Retail and Enterprise platforms. Our goal is to build, scale and guard the systems that delight our guests. To do so, you will:

• Design, write and build tools to improve the reliability, latency, availability, and scalability of Target’s e-commerce/Retail and Enterprise products
• Instrument systems for reliability, performance, and efficiency of Guest experiences
• Define, drive adoption, and enforcement of service level objectives at both service and experience levels
• Influence, design, and create new architectures, standards, methods, and best practices for systems
• Root-cause complex problems involving multiple parties, networks, hardware, and software that relate to scaling and performance
• Champion high availability for critical systems, and systematically root out single points of failure
• Develop partnership and be able to work side by side with the Product team.

Responsibilities:

• Strive to eliminate downtime and improve the manageability of infrastructure and application services
• Set standards for deployments at scale, infrastructure reliability, and scalability.
• Iterate, revisit, and optimize service availability, scalability, and performance
• Influence engineering teams across Target with customer focus, world-class quality, effective communication, decisive, fast-moving solutions, quick and constructive resolution of conflicts
• Manage service availability and scalability through process, tools, and automation. Perform post-mortems and optimize incident response processes
• Lead incident response for production incidents; Drive investigation, analysis and troubleshooting to resolve production incidents and systematically drive down detection and mitigation times.

Requirements:

• BS or MS in Computer Science or equivalent experience
• 7 years or more building and scaling distributed systems leveraging web-scale technologies like Linux, Apache, MongoDB, Python, Oracle RDBMS, Redis, Postgres and Hadoop.
• Experience with Linux/Unix internals and systems services like DNS, DHCP, TFTP, IPtables, SMTP, as well as networking protocols such as TCP, UDP, and HTTP.
• Experience with monitoring systems, tracing, and observability to manage large-scale systems and 24x7 availability.
• Experience with building and maintaining application stacks in a Hybrid Cloud environment, as well as expertise with Google Cloud Platform (GCP) is a plus.
• Programming experience in one or more of the following languages: Go, Java, Python, Ruby, Shell, and CI/CD tools such as Travis, Drone, Jenkins.
