Sounds awesome, right? Now, let’s make sure you’re a good fit for the role:

Key Responsibilities

Distributed Systems & Event-Driven Architecture

- Architectural Trade-offs: Evaluate and articulate the trade-offs of asynchronous vs. synchronous communication, decoupling strategies, fault isolation, and scalability in distributed environments.
- Reliable Messaging & Data Consistency: Design and implement mechanisms that guarantee data consistency across distributed boundary lines (addressing challenges such as dual-writes, transactional integrity, and message handling guarantees).
- Resilience & Failure Recovery: Engineer robust fault-tolerance strategies beyond basic retries, ensuring systems gracefully handle partial failures, network partitions, and cascading outages.

2. System Design & Technical Communication

- End-to-End System Design: Lead system design initiatives for complex banking scenarios with minimal supervision—taking raw business requirements and turning them into scalable architectures.
- Visual & Verbal Clarity: Translate abstract concepts into structured architectural diagrams, presenting clear design rationales during technical refinements and discussions.

3. Software Delivery & Engineering Standards

- Production Code Quality: Write, maintain, and test high-throughput, secure backend applications using modern .NET / C#.
- Cloud & Platform Operations:



Work with distributed cloud infrastructure, containerized environments, and continuous delivery pipelines to ensure reliable deployments and system observability.
- Testing Strategies: Build comprehensive testing suites tailored for distributed systems, ensuring reliability across integration boundaries and asynchronous workflows.

Must-have Skills

- Senior-Level Experience: Proven track record building enterprise-grade backend systems using modern .NET / C# in production environments.
- Distributed Cloud Systems: Strong overall experience engineering applications on modern cloud platforms (e.g., Azure, AWS, or GCP), with practical familiarity with containerization, cloud networking, infrastructure provisioning, and continuous integration/deployment.
- Asynchronous & Messaging Concepts: Deep practical understanding of distributed messaging systems, event streams, and the operational challenges of managing decoupled services.
- Language & Communication (Strict Requirement): English C1 (Fluent). You must be able to express technical ideas fluidly on the spot, navigate ambiguous architectural questions, and collaborate seamlessly in real-time technical refinements.

Nice-to-have:

- AI Tooling Proficiency: Leverage one or more AI tools to optimize and augment day-to-day work, including drafting, analysis, research, or process automation. Provide recommendations on effective AI use and identify opportunities to streamline workflows.
- AI-Assisted Workflow: Practical experience integrating modern AI development tools into your daily workflow to optimize productivity.
