About The Position

We're building a new team that uses AI coding agents as co-workers to accelerate the migration of our PIM (Production Information Management) platform into a suite of lightweight, custom full-stack applications where end users can directly manage product data. As a Senior Software Engineer (Software Engineer III) you will be involved in the full systems life cycle and responsible for designing, coding, configuring, testing, implementing and supporting application software and systems that are delivered on time and within budget. You'll partner with engineers, architects, and product managers to turn complex data-management workflows into clean, maintainable apps. In addition to mentoring junior engineers, you will work closely with technical teams, stakeholders and product managers to understand the business requirements that drive the analysis and physical design of technical solutions. Chicago, IL is the preferred location with a hybrid work environment (2 days per week in the Merchandise Mart office). We will also consider highly qualified remote candidates who are willing to travel to Chicago for onboarding and occasional team meetings. Onsite onboarding will be required.
