Job Description

Payroll Integration Developer
Client-Facing | Data-Driven | Mid–Senior Level

About Us
We are a fast-growing benefits technology organization partnering with mid-market and enterprise employers across the U.S. to solve complex data and administration challenges. Our platform connects HR, payroll, and vendor systems to streamline eligibility, deductions, compliance, and ongoing plan management. We operate with a “work anywhere” mindset, value long-term client relationships, and are continuing to expand due to increased demand for our services. Our team culture emphasizes collaboration, accountability, and a genuine commitment to doing right by clients and partners.

About The Role

We’re looking for a Payroll Integration Developer who can build, configure, and launch payroll data integrations from the ground up. This is not a heads-down processing role - you’ll partner directly with clients, lead requirements discussions, and translate business logic into technically sound payroll and benefits data feeds.

You will work across multiple concurrent projects, collaborating with internal teams and external vendors to build and validate file-based integrations that drive accurate payroll deductions, eligibility management, and ongoing plan updates. Success in this role requires analytical depth, technical competence, and strong client-facing communication skills.

What You'll Be Doing

• Own end-to-end development of new data exchanges, including requirements gathering, build, testing, launch, and transition to ongoing support.
• Lead calls with clients and vendor partners to uncover needs, clarify file logic, and capture specs.
• Build and validate payroll deduction and HRIS data feeds, including field mapping, data cleansing, and transformation logic.
• Apply programming-style logic (e.g., conditional mapping, transformation rules) to large, complex datasets.
• Develop and maintain file-based interfaces (CSV, flat files, XML) between HR/benefits/payroll systems and external vendors.
• Utilize XML-based transformation technologies (XSLT, XPath, or similar) and basic scripting (JavaScript or comparable languages) to implement mapping and logic rules.
• Interpret and configure complex mapping tables for example deriving vendor codes using plan IDs, coverage tiers, and plan classes.
• Work confidently with dates, numeric calculations, and payroll-related logic (effective/term dates, contribution amounts, deduction calculations).
• Analyze input and output files to identify root causes for unexpected records, suppressed data, or incorrect transformations.
• Coordinate with internal project managers and configuration teams to ensure timelines and requirements are aligned.
• Document technical specifications, file layouts, transfer protocols, and testing results.
• Ensure a smooth transition into ongoing support, including final documentation and resolution of outstanding issues.

What You Bring

• Bachelor's degree preferred
• 4+ years working in data integrations, HR/payroll connectivity, SaaS onboarding, or file-based implementation work
• Hands-on experience building or maintaining payroll or HRIS integrations, not just supporting or monitoring them.
• Strong Excel and XML/XSL skills; familiarity with SQL, JavaScript, or similar tools is beneficial
• Ability to understand and apply programming-style logic in a non-software engineering role
• Experience working directly with clients - comfortable leading calls and translating requirements
• Highly organized and able to manage multiple workstreams with overlapping deadlines
