Role Overview
We are seeking highly skilled Golang Engineers to join a fast-paced engineering team responsible for building and enhancing next-generation banking and payment platforms. The successful candidate will play a critical role in designing, developing, and operating scalable backend services supporting high-volume, mission-critical financial transactions.
You will work within a modern cloud-native environment, building resilient microservices and event-driven systems that support secure, real-time transaction processing across a complex banking ecosystem. The role requires strong engineering fundamentals, deep Golang expertise, and experience operating distributed systems at scale.
Working closely with Architects, Product Owners, SRE, DevOps, and Platform Engineering teams, you will contribute to the end-to-end software development lifecycle while ensuring solutions meet the highest standards of performance, security, resilience, and observability.
Key Responsibilities
Software Engineering
- Design, develop, and maintain robust backend services using Golang.
- Build highly scalable APIs and microservices supporting banking and payment capabilities.
- Develop reusable libraries, frameworks, and engineering standards.
- Participate in system architecture and technical design discussions.
- Ensure code quality through automated testing, code reviews, and engineering best practices.
- Troubleshoot and resolve complex production issues.
