Core Developer

 
CardFlight is looking for a software developer interested in moving millions of dollars every day. In this role, you will work on software at the core of CardFlight’s products. You will write code that supports our SDKs, enabling custom mobile payment applications, as well as our out-of-the-box mobile payments app, SwipeSimple. Your responsibilities will include both coding and DevOps tasks; not only will you write the code, you’ll ensure it behaves itself at scale in production.
Experience with payment systems is desirable, but in no way necessary. The right developer for this role believes reliability, performance, and maintainability are equal top-level concerns. While the current tech stack is Ruby-based, you should be able to learn new technologies quickly and be motivated by using the right tool for the job. This is an opportunity to expand the foundation of an established company in the payment space, and see first-hand what it takes to build scalable, fault-tolerant software that businesses trust every day.

The Responsibilities

  • Develop & maintain scalable back-end processes
  • Own communication with the largest payment processors in the country
  • Expand our products’ integration with new payment processors
  • Spend up to 10% of your time contributing to Open Source software
  • Unify payment processing flows and provide greater visibility into issues

Minimum Qualifications

  • BS in Computer Science or equivalent practical experience.
  • Experience building scalable systems
  • Experience with relational data access patterns

Desirable Skills & Experience

  • 2+ years of professional development experience
  • Professional Ruby development experience
  • Non-Ruby development experience as well
  • Some experience with Amazon Web Services
  • Experience with payment systems

 

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status
