- Collaborate with cross-functional teams (Backend, Mobile, Product, and QA) to define and deliver new features across the payments and EV ecosystem.
- Take ownership of features throughout the entire development lifecycle, from design and implementation to deployment and production support.
- Provide mentorship and technical guidance to junior developers, fostering best practices in coding, design patterns, and architectural decisions.
- Debug, optimize, and maintain existing backend services, SDKs, mobile applications, and UI components to ensure seamless functionality and high-quality performance at scale.
What Makes You a Great Fit:
Backend (Mandatory)
- Bachelor's degree in Computer Science, Software Engineering, or a related field.
- 5+ years of experience in software development, with significant experience building and scaling backend systems in production — payments experience strongly preferred.
