Software Developer (Junior to Mid-Level)

| Chicago
About Us
As a member of the CardX team, you’ll be part of a fast-paced, rapidly growing company that’s changing the way businesses accept credit cards. We’re focused on making payments fairer for everyone by helping businesses achieve compliance with regulations that promote transparency and consumer choice. With CardX, there’s no more choosing between reducing margins or raising prices to offset rising credit card rates, which causes cash and debit payers to subsidize costly credit card rewards. 
In a complex and changing regulatory landscape, CardX delivers technology-enabled automated compliance so that our clients can focus on what’s most important to them. From software that integrates seamlessly with businesses’ needs to exceptional customer support, we are committed to innovation and excellence, and we’re looking to grow our collegial and highly motivated team. 
At CardX, you’ll have the opportunity to define new processes, take charge of cornerstone projects, and deliver solutions for industry-leading businesses. Every step of the way, you’ll be supported by talented colleagues who are, like you, energized by excellent work.
Position Details
The Software Developer will be responsible for building and maintaining the newest generation of CardX products. This role is collaborative and cross-functional, involving frequent communication with other members of the development team as well as stakeholders and the operations team.
We’re hoping to bring on new teammates with a passion for building new things, consistent attention to detail, effective communication, strong work ethic, commitment to excellence in product delivery, and the desire to thrive within a fast-paced, rapidly-growing company.
