• Work closely with cross-functional partners to gather functional requirements, conduct system analysis, map workflows and processes, and translate business needs into clear technical specifications and implementation plans.
• Perform code reviews, uphold development standards and best practices, troubleshoot production issues involving performance, functionality, and integrations, and proactively recommend improvements. Provide technical leadership and mentorship to developers across skill levels while contributing ideas informed by current technologies and industry practices.

• 5+ years of GenTax development experience: Candidates must have at least five years of experience designing and developing solutions within the GenTax system, including strong hands‑on proficiency with SQL and C# in Visual Studio.

• Business and systems analysis experience: Strong background gathering functional requirements and converting them into technical specifications through system analysis, workflow design, and process design.

Preferred Qualifications

• Experience supporting Tax Commission business processes within the GenTax environment is strongly preferred. Candidates with experience implementing data‑conversion processes during software version upgrades will stand out.
• The ideal candidate brings strong analytical, troubleshooting, communication, and collaboration skills; can work independently while partnering effectively with a technical team; and is comfortable mentoring team members at different experience levels. Prior IT Architect experience is a plus.
