A Look into Your Day

Daily Workflow Snapshot
You start the day by reviewing alerts, dashboards, and overnight run logs to verify scheduled transfers and ETL activity completed cleanly. You then validate a few key data points against expected results-paying close attention to anything that could affect downstream reporting or customer-facing channels-and open follow-ups for items that fall outside established tolerances.

Midday typically includes touchpoints with internal teams and vendor partners to confirm how a new or adjusted integration should behave in production. You translate those conversations into clear requirements, outline dependencies, and align on a realistic delivery timeline.

As work progresses, you assess test results, refine configuration notes, and keep design/support documentation current, including evidence needed for audit and change control. When an incident arises, you shift quickly into triage: communicate status, document what you find, and coordinate a controlled recovery and verification. Throughout the day, you balance focused build time with responsive collaboration in a work-from-home flexible environment.

What We're Looking For

The System Integration Analyst supports reliable, secure data exchange between key banking platforms. In this mid-level position, you will help build, maintain, and optimize integrations across Jack Henry environments (core banking, digital banking, digital onboarding, loan origination, CRM) and other enterprise systems-enabling efficient operations and a consistent customer experience.

You will analyze business and technical integration needs, translate them into clear requirements, and deliver well-documented solutions. Work includes designing, configuring, developing, testing, and supporting integrations using approved tools and methods such as APIs, ETL, file transfers, MoveIT, middleware, and scripts. You will write and troubleshoot scripts for data transformation/validation, monitor integration jobs and transfers, investigate production incidents with root-cause analysis, and coordinate timely resolution. You will also maintain detailed artifacts (data mappings, specs, workflows, testing evidence, support procedures, and change logs) and assess integration impacts during upgrades, releases, and new implementations while meeting security, data integrity, access control, and regulatory expectations.

- 3–5 years of experience
