About us
We’re building a high-load payment platform that processes thousands of transactions around the clock.
Our engineering challenges go far beyond typical CRUD applications. We build distributed systems where reliability, scalability, performance, and fault tolerance are critical. Our platform is built around an event-driven architecture using .NET 9, Kafka, PostgreSQL, Redis, Docker, and modern cloud-native engineering practices.
If you enjoy building robust backend services and want to work on real-world payment infrastructure, we’d love to meet you.
What you’ll do
* Build and improve core services of our payment platform. * Develop integrations with payment providers. * Implement new backend features and platform capabilities. * Improve transaction processing and internal platform services. * Participate in technical discussions and architecture reviews. * Work closely with Senior Engineers on designing scalable solutions. * Collaborate with our Connector team (Python / TypeScript). * Participate in code reviews and continuously improve engineering quality.
We’re looking for someone who has
Strong .NET expertise
* 3+ years of commercial backend development. * Strong experience with C# and .NET. * Experience with ASP.NET Core. * Good understanding of asynchronous programming. * Experience building scalable backend applications. * Experience with Dependency Injection, background services, and REST APIs.
Distributed Systems
Practical experience with or a good understanding of:
* Event-driven architecture * Microservices * Idempotency * Reliable messaging * Distributed transactions
Messaging
Experience working with Kafka or another message broker (RabbitMQ, Azure Service Bus, NATS, etc.) is a strong advantage.
Databases & Caching
* PostgreSQL * Dapper or Entity Framework * Ability to write efficient SQL queries * Redis * Basic caching strategies
Infrastructure
* Docker * Experience working in containerized environments * Kubernetes or Docker Swarm will be a plus
FinTech Experience
Experience with payment systems, FinTech products, or other high-load backend systems will be a strong advantage.
Engineering mindset
You value clean, maintainable code and enjoy solving technical challenges.
You regularly work with:
* Unit testing * Logging * Debugging * Monitoring * Code reviews
AI-assisted Development
AI is part of our daily engineering workflow.
We expect engineers to confidently use Cursor, Claude Code, GitHub Copilot, or similar tools while maintaining full ownership of the produced code.
Nice to have
* Lua / LuaJIT * OpenAPI-first Development * openapi-generator * Python or TypeScript * Git Submodules * Dynamic configuration through event buses
Tech Stack
