Job Title

About Our Project:

We're a group of passionate professionals working on building the future of payments. With millions of happy customers and a passion for innovation, we're now expanding our team - literally and metaphorically.

About the Role

  • We're looking for an experienced Application Developer to help us automate and scale our entire chargeback process across both acquiring and issuing operations.
  • In this role, you will work on building and refactoring robust dispute flows, integrating with major card networks like Visa and Mastercard, and leveraging AI APIs to bring intelligence and automation to the core of our operation.
  • You'll be responsible for connecting internal and external APIs, designing scalable architecture, and making our dispute handling smarter, faster, and more autonomous.

Responsibilities:

  1. Refactor and scale existing chargeback and dispute handling flows written in Ruby.
  2. Integrate with external APIs from Visa, Mastercard, and other partners.
  3. Work with AI APIs (generative and/or machine learning) to automate analysis, decision-making, and documentation.
  4. Build resilient services to support end-to-end chargeback processes for both issuing and acquiring.
  5. Collaborate with product, data, and operations teams to deeply understand business rules and pain points.
  6. Write clean, maintainable code and contribute to a culture of continuous improvement.

Requirements:

  • Strong experience in application development with at least 3 years of Ruby/Rails development.
  • Experience with RESTful APIs, background jobs, and service integrations.
  • Passion for refactoring legacy code and designing scalable solutions.
  • Understanding of payment networks (Visa/Mastercard) and/or chargeback operations is a big plus.
  • Familiarity with AI tools or APIs (e.g. OpenAI, Langchain, ML models) is a nice-to-have.
  • Ownership mindset and a willingness to build from scratch.

Join Us:

We're not just engineering solutions; we're building a smarter, AI-driven future for payments—together.
