At the core of the role is backend engineering in C#/.NET, combined with deep PostgreSQL work. You’ll work on high-throughput systems connected to real financial flows, where correctness and reliability are critical. As part of the enterprise team, you’ll help shape and evolve the platform itself.

What You'll Do (Responsibilities):

• Design and implement backend services in .NET, supporting high-throughput financial operations (accounts, wallets, transactions).

• Own and evolve PostgreSQL-based data models, queries, and performance optimization across multiple services.

• Work within a microservices ecosystem, handling versioning, dependencies, and service communication.

• Contribute to and extend the core architecture, enabling scalable orchestration of financial workflows.

• Build and maintain server-to-server API integrations, ensuring reliability and correctness of critical payment flows.

• Ensure data accuracy and consistency

• Collaborate closely with QA and Enterprise product teams to validate complex business scenarios and edge cases.

• Develop and maintain automated deployment pipelines (GitLab CI/CD) for large-scale distributed systems.

• Participate in architecture discussions within the core platform team (Tech Lab), influencing system design decisions.

• Monitor and improve system performance, reliability, and observability across services.
  

What You’ll Need To Be Successful In This Role:

• Strong backend development experience with C# / .NET

• Experience working with distributed systems / microservices architecture

• Strong understanding of data consistency, transactions, and financial correctness

• Strong hands-on experience with PostgreSQL in production environments, including query optimization, indexing strategies, and performance tuning

• Knowledge of message brokers (RabbitMQ, Kafka) and asynchronous communication is a plus.

Great to have:

• Experience with CI/CD pipelines (GitLab preferred)

• Familiarity with automated deployments in complex environments

• Experience with Docker / containerized services
