About the Role
Our firm is partnering with a Fortune 50 retail leader to identify a Senior Full Stack Software Engineer who will support a large enterprise application portfolio within their indirect planning engineering organization. This team owns and modernizes a broad set of production applications that power critical business capabilities across one of the largest retail supply chain and merchandising operations in the country.
The environment is built on a modern, event-driven architecture composed of a significant number of Java and Kotlin Spring Boot microservices, along with React-based micro front-end applications. The ideal candidate will be able to ramp up quickly, operate effectively within a complex enterprise codebase, and contribute confidently across both backend and frontend layers.
This opportunity is well suited for an engineer who enjoys working in large-scale systems, improving existing applications, and helping strengthen security, maintainability, performance, and delivery practices in a fast-moving retail technology environment. Job Description
The Senior Full Stack Software Engineer will join a team responsible for maintaining, modernizing, and enhancing a wide range of production applications supporting enterprise planning functions. Day-to-day work will involve building new features, refactoring legacy code, remediating security vulnerabilities, and collaborating cross-functionally to deliver high-quality software.
Key responsibilities include:

• Contributing across backend and frontend applications within a large enterprise codebase.
• Reading, debugging, and improving code written by others while delivering production-ready features.
• Refactoring and modernizing legacy applications to strengthen maintainability and performance.
• Identifying and remediating security and quality issues, including CVEs and dependency upgrades.
• Balancing new feature development with meaningful technical debt reduction.
• Designing and supporting microservice-based applications in an event-driven architecture.
• Collaborating across engineering, product, platform, and architecture teams to deliver reliable solutions.
• Writing clean, maintainable, and well-tested code aligned with enterprise standards.
• Leveraging AI-assisted development tools responsibly to improve productivity while safeguarding quality and security.

This role also places a strong emphasis on improving the security posture of existing applications. Engineers who have proactively reduced risk in production systems will be especially well aligned with the team's goals. Qualifications
