Senior .NET Developer - Fintech

Location: Belgrade, Serbia
Employment Type: Full-time | Hybrid

About Us

We are a fast-growing company delivering operational and technology support for financial services providers. We build real, production-grade systems: highly available, regulated, distributed platforms that move money, data, and trust.

As our systems grow in transactional volume, regulatory demands, and third-party integrations, we need people who can turn these challenges into working, reliable solutions.

What You’ll Do

• Design, build, and evolve production-grade .NET services in a distributed fintech environment.
• Develop and maintain microservices running in Azure (App Services, Functions, AKS).
• Work on event-driven and integration-heavy systems (APIs, Service Bus, external partners).
• Refactor existing codebases to improve performance, stability, and maintainability.
• Own your services end-to-end: development, testing, deployment, monitoring.
• Collaborate closely with architects, DevOps, product, and compliance.
• Make and document technical decisions with incomplete information, balancing risk, quality, and delivery.

Tech Must-Haves

You should be hands-on and battle-tested with:

• Strong .NET / C#, including correct async/await usage, solid understanding of memory, threading and performance, and the ability to profile and diagnose production issues.
• Real Azure experience across App Services, Azure Functions, AKS, Service Bus, Key Vault, and Azure DevOps.
• Microservices and distributed systems.
• T-SQL, including query design, performance tuning and indexing.
• External integrations and APIs, including third-party and fintech service providers.
• Angular, with practical production experience.
• Refactoring and testing.

What We Value in This Role

• You finish things, not just start them.
• You are comfortable with ambiguity (requirements evolve, regulations change, priorities shift).
• You take ownership instead of waiting for perfect specs.
• You explain technical decisions through reasoning and impact, not authority.
• You focus on delivering working, maintainable systems rather than concepts.

What We Offer

• Competitive compensation aligned with seniority
• Private health insurance
• Fit Pass Premium membership
• Hybrid work arrangement
• Complex, meaningful fintech projects
• International exposure and long-term product roadmap

Why This Role Exists

Our platform handles payments, digital banking components, and regulated financial flows. This means performance, reliability, and clarity matter - every day, not just during releases. You’ll build systems that scale, operate reliably in production, meet regulatory requirements, and remain readable and maintainable over time.
