About the Role

Join a team building mission-critical systems for global payment processing. As a .NET Backend Developer, you'll play a central role in developing and maintaining services that power end-to-end acquiring solutions — from transaction capture and authorization to settlement and reconciliation.

What You'll Do

  • Design, implement, and support scalable back-end services using .NET Core or .NET Framework with a focus on performance, reliability, and security
  • Integrate with third-party payment processors, card networks, and acquiring platforms through RESTful APIs and messaging protocols
  • Develop modules for financial reconciliation, ensuring accuracy and consistency across transaction flows
  • Collaborate with product, quality assurance, and infrastructure teams to deliver compliant, production-ready systems
  • Participate in architectural discussions, code reviews, and continuous improvement of development practices

What We're Looking For

  • Bachelor’s degree in Computer Science, Engineering, or a related field
  • At least 5 years of hands-on experience in backend development with C# and .NET technologies
  • Proven work with microservices, REST APIs, and distributed systems
  • Familiarity with messaging platforms such as Kafka, RabbitMQ, or AWS SQS/SNS
  • Experience working with both SQL and NoSQL databases including SQL Server, PostgreSQL, or MongoDB
  • Knowledge of cloud platforms, particularly AWS, and experience with serverless architectures
  • Understanding of containerization using Docker and orchestration with Kubernetes
  • Strong grasp of CI/CD pipelines and version control with Git
  • Background in payment systems — especially acquiring workflows, transaction lifecycles, and settlement processes
  • Experience applying design patterns and agile methodologies in complex, high-availability environments

Nice to Have

  • Familiarity with PCI DSS standards and security best practices in payment processing

Work Environment

This role supports flexible working arrangements — you may work remotely, in-office, or in a hybrid model based on your preference and project needs. You’ll contribute to international projects with teams that value transparency, technical excellence, and continuous learning.

Our Culture

We foster a culture built on trust, open communication, and meaningful mentorship. You’ll be encouraged to question assumptions, share ideas, and take ownership of your work. Growth isn’t just encouraged — it’s embedded in how we operate.
