Wizeline, a general AI-native technology solutions provider, develops cutting-edge, AI-powered digital products and platforms. We partner with clients to leverage data and AI, accelerating market entry and driving business transformation. As a global community of innovators, we foster a culture of growth, collaboration, and impact. With the right people and the right ideas, there’s no limit to what we can achieve Sounds awesome, right? Now, let’s make sure you’re a good fit for the role: Key Responsibilities

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

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.
