Full-time, Internship

Posted 4 days ago

Job description

Founded in 2017, NinjaHoldings works to give everyday Americans better access to financial services than traditional institutions typically provide. Through our CreditNinja and NinjaCard brands, we offer digital banking and lending products designed for consumers often overlooked, paired with incentives that support long-term financial improvement. Our Edge brand extends this expertise to other companies, providing underwriting, fraud detection, and analytics services. Headquartered in Chicago with a distributed global workforce, we are a lean, growing organization committed to advancing consumer finance in the US.

This internship is designed to give you exposure to real-world software development, mentorship from experienced engineers, and the opportunity to make meaningful contributions to projects that impact thousands of customers.
You'll be paired with a mentor and collaborate with developers, QA engineers, and product managers. While you won't be expected to know everything from day one, you'll be encouraged to learn, ask questions, and grow your technical skills in a supportive and fast-paced environment.

  • Identity (managing customer data securely)
  • Decisions (automated underwriting and marketing lead systems)
  • Portfolio Management (lifecycle of lending/banking products and payment integrations)

Ideal Candidate Will Have:
  • Incoming junior or senior currently pursuing a degree in Computer Science, Software Engineering, or a related field
  • Familiarity with Ruby on Rails (or willingness to learn)
