Senior Applications Support Engineer

Job Description

Job Description

Advantage Tech is searching for an Applications Support Engineer to join their client's team Kansas City, KS.

The client is moving towards running their Retail operations on top-tier SaaS and enterprise products. They are currently midway through a significant technology modernization, transitioning from legacy COBOL-based systems to a modern, integrated environment. As a Senior Application Support Engineer, you are a critical technical anchor for this hybrid ecosystem. This is a support-centric role where your primary mission is to ensure operational continuity. You will act as a functional lead for high-priority production incidents, maintaining the health of our evolving environment and using your Java expertise to fix, patch, and optimize the custom integrations that keep our systems running.

 

Key Responsibilities

• SaaS Ecosystem Maintenance: You will monitor the health of our integrated SaaS platforms, manage vendor-related issues, and ensure that our custom integration layers remain stable and secure.
• Java Patching & Enhancement: When our vendor products or modernization efforts require customization or integration fixes, you will jump into the code. Deliver high-quality Java/MFT patches, bug fixes, and maintenance enhancements.
• System Stability & Reliability: Proactively identify recurring pain points and performance bottlenecks. Use your SQL skills to analyze logs, optimize queries, and automate routine support tasks to prevent future system downtime.
• Technical Stewardship: Review peer changes with a focus on safe deployment and regression testing. You are responsible for ensuring that all support activities maintain the integrity of our production environment.

Technical Requirements

• Java/Spring Proficiency: 3+ years of Java/Spring Boot experience. Your strength should be in navigating, debugging, and patching existing codebases, rather than development.
• Integration Troubleshooting: Experience debugging, web services, and file-transfer processes. You should be adept at determining whether an issue lies within a SaaS vendor’s platform, our integration layer, or legacy systems.

Preferred Qualifications

• Specialized Systems: Experience with Java batch (JBeret), IBM App Connect (ACE), or file-transfer software (e.g., Cleo Harmony).

Why This Role?

• Be the Expert: Your role is vital. You aren't just one of many developers; you are the technical expert who ensures our business stays running.
• Be at the Center of Transformation: You will be instrumental in supporting our Retail domain as we modernize our tech stack, gaining valuable experience in maintaining the bridge between legacy architecture and modern SaaS solutions.
