Lead Systems Engineer

Our Order Management System (OMS) is the platform behind how AutoZone fulfills orders across eCommerce (B2C, B2B) and in-store channels - processing millions of orders a year and growing. We're looking for a Lead Systems Engineer to provide hands-on technical leadership across OMS: designing and building cloud-native services, setting technical direction for a team of engineers, and driving the modernization of legacy integrations (Mainframe, Talend, EDI).

This is a player-coach role. You'll spend real time in the codebase - designing services, reviewing code, resolving production issues - while also setting technical standards, mentoring engineers, and owning delivery across a functional area. You'll work closely with enterprise architects, product owners, and QA in a fast-moving environment that embraces AI-augmented development workflows.

Technical Leadership and Delivery

- Own end-to-end technical delivery for a functional area of OMS (e.g., Order Placement, Order Modifications, Order Lookup, Shipping/Routing), from design through production support

- Translate high-level business requirements into detailed functional requirements, technical designs, and development-ready JIRA tasks

- Lead technical design reviews and code reviews; set and enforce coding standards, architectural patterns, and clean-code practices across the team

- Drive technical readiness ahead of major release cycles - proactively surface risks, coverage gaps, and dependencies before development begins, not after

Hands-On Engineering

- Design and build scalable, cloud-native microservices using Java and Spring Boot, deployed on GCP (GKE)

- Architect solutions for high-throughput, event-driven workflows (Pub/Sub, Kafka-style messaging) with an eye toward fault tolerance, decoupling, and observability

- Maintain a consistent, visible individual contribution - commits, PRs, and production deployments - that sets the technical bar for the team

Team Development and Mentorship

- Mentor engineers through structured peer code review, technical coaching sessions, and module ownership assignments

- Build team self-sufficiency by delegating production deployment responsibility, module ownership, and meeting facilitation to grow junior and mid-level engineers

- Champion AI-assisted engineering practices (e.g., Claude Code) across the team to accelerate design, implementation, and review

Resiliency, Security, and Operations

- Ensure designs account for security, redundancy, disaster recovery, data integrity, and monitoring from the outset

- Own change management discipline for your area - mission plans, Change Requests, runbooks, and rollback procedures - to support a zero major/critical incident bar

- Participate in on-call rotation and lead incident response, root-cause analysis, and postmortems for your functional area

- Drive proactive vulnerability remediation and dependency upgrades (Spring Boot, Java, Terraform modules, Helm charts) ahead of pipeline enforcement deadlines

Experience

- 9+ years of experience in application development

- Strong backend development and design experience with Java and Spring Boot microservices

- Experience designing and building highly scalable, distributed, cloud-native systems

- Experience modernizing legacy/brownfield systems alongside greenfield development

- Background in Agile/DevOps environments supporting large-scale enterprise implementations

Technical Skills

- Advanced Java and Spring Boot expertise; strong REST API design and microservices architecture

- Hands-on experience with GCP (GKE, Pub/Sub, BigQuery) or equivalent cloud platform

- Solid understanding of CI/CD practices and pipeline integration (GitLab CI/CD, Terraform, Helm)
