Lead Software Engineer – Systems Management Tools

About the Team

The Technical Infrastructure organization designs, builds, and operates the enterprise platforms that power Williams-Sonoma, Inc. across Ecommerce, Supply Chain, Corporate, Retail, and Distribution Center environments.

Within this organization, the Systems Management Tools team develops and supports the enterprise observability, logging, monitoring, and automation platforms used across the company. The team is responsible for the software engineering, architecture, and operational excellence of OpenSearch, enterprise logging services, Kubernetes-hosted tooling, Kafka ingestion pipelines, Logstash processing, monitoring, and internally developed operational tools that enable engineering teams to build, operate, and troubleshoot enterprise applications at scale.

The team partners closely with application engineering, platform engineering, infrastructure, cloud, security, network, DevOps, Site Reliability Engineering (SRE), and operations teams to deliver highly available, scalable, and secure observability platforms supporting both Ecommerce and Supply Chain business units. This reflects the team's documented ownership of OpenSearch clusters, Rancher/Kubernetes environments, Kafka ingestion, Filebeat onboarding, Logstash, and operational tooling.

About the Role

As Lead Software Engineer – Systems Management Tools, you will provide technical leadership for the design, development, architecture, and lifecycle management of Williams-Sonoma's enterprise observability platform and internally developed operational tools.

You will lead software engineering initiatives centered around OpenSearch, enterprise logging, Kubernetes-based platform services, monitoring, automation, and operational tooling while helping define the technical roadmap for reliability, scalability, security, and operational excellence across the observability ecosystem.

This role is ideal for a highly experienced software engineer who combines deep application development expertise with distributed systems knowledge, platform engineering experience, and operational excellence. You will lead complex engineering initiatives, mentor engineers, influence architecture, and partner across Infrastructure, Platform Engineering, Security, Cloud, and Application Development organizations to deliver enterprise-scale systems supporting mission-critical Ecommerce and Supply Chain platforms.

The role aligns well with WSI's Lead Software Engineer expectations of authoring technical designs, technical ownership of delivery, reviewing architecture, influencing engineering practices, mentoring engineers, and driving cross-functional initiatives.

Design scalable solutions supporting high-volume log ingestion, distributed search, enterprise monitoring, and operational analytics across Ecommerce and Supply Chain platforms.

Lead cross-functional software engineering initiatives involving OpenSearch platform upgrades, Kubernetes platform enhancements, logging modernization, observability improvements, and enterprise automation projects.

Partner with Infrastructure Engineering, Cloud Engineering, Platform Engineering, Security, Application Development, and Site Reliability Engineering teams to deliver resilient enterprise platform services.

Guide incident response, production troubleshooting, root cause analysis, post-incident reviews, and long-term engineering improvements for enterprise observability services.

Establish engineering metrics, operational dashboards, performance benchmarks, and platform health reporting supporting service reliability and continuous improvement.

Evaluate emerging technologies related to AI-assisted operations, observability, distributed search, platform engineering, automation, and software development.

Mentor engineers through architecture reviews, code reviews, design discussions, technical coaching, and software engineering best practices.

Drive documentation excellence across architecture decisions, API specifications, operational runbooks, deployment standards, software lifecycle documentation, and engineering standards.

Represent the Systems Management Tools team in enterprise architecture reviews, technology governance, engineering strategy discussions, and cross-functional planning.

Participate in critical production support, after-hours maintenance, and major incident response as required.
