Reliability and quality are fundamental to the platform, so we're seeking product-minded engineers with proven experience in cloud-native distributed systems and a strong sense of ownership throughout the software development lifecycle. In this role, you'll be expected to contribute to architectural decisions, clearly articulate the trade-offs behind your technical choices, and take features from business refinement through implementation, deployment, and production monitoring. You'll work with modern engineering practices to build decoupled, maintainable systems that scale reliably in production., * Engineering Seniority: 5+ years of experience designing and deploying complex, high-throughput backend systems using .NET. * Cloud-Native Expertise: Deep, hands-on experience with AWS, particularly containerized workloads (ECS/EC2) and messaging services (SQS/SNS). * System Design Mastery: Strong understanding of SOLID principles, dependency injection lifetimes, and the Core middleware pipeline. * Concurrency Discipline: Expert knowledge of asynchronous programming in C#. You understand how the thread pool works and why synchronous blocking (for example, using `.Result` or `.Wait()`) can severely impact the scalability and reliability of web APIs. * API Design: Strong understanding of RESTful APIs, idempotent operations, and global exception-handling strategies. * Communication: Advanced or fluent English, with the ability to clearly communicate architectural decisions and technical trade-offs to stakeholders and cross-functional teams. It Would Be Fantastic If You Also Have: * Production experience with streaming platforms such as Kafka, Kinesis, or RabbitMQ. * Strong understanding of AWS services and cloud-native architectures. * Practical experience with LLMs and Generative AI using .NET or Python, particularly for AI-assisted engineering workflows and SDLC automation. ## Description Your role goes beyond writing C# code. You are expected to own the delivery pipeline end to end: * Refinement: Challenge ambiguous business requirements, analyze acceptance criteria, and ensure technical feasibility. * Architecture: Design decoupled, scalable solutions using Event-Driven Architecture (EDA) patterns. * Execution:Write highly concurrent, thread-safe applications using .NET 8 or later, with a strong preference for composition over inheritance. * Verification: Treat Test-Driven Development (TDD) as an essential engineering practice by writing robust unit and integration tests using xUnit and WireMock to prevent regressions. * Delivery & Operations: Deploy through modern CI/CD pipelines and proactively monitor production telemetry using tools such as AWS CloudWatch, New Relic, and GitHub Actions to ensure rapid troubleshooting and operational excellence. Tech Stack: * Core: C#, .NET 8+, Core * Architecture: Microservices, Event-Driven Architecture (EDA), Distributed Systems * Cloud & Messaging: AWS (ECS, EC2, SQS, SNS, S3) * Databases & Caching: SQL, NoSQL, Redis, Valkey, DynamoDB * Infrastructure & CI/CD: Terraform, GitHub Actions, TeamCity * Quality Assurance:xUnit, WireMock, SpecFlow ## Related Videos - [Leveraging Real time data in FSIs](https://www.wearedevelopers.com/videos/806-leveraging-real-time-data-in-fsis) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Accelerating Authentication Architecture: Taking Passwordless to the Next Level](https://www.wearedevelopers.com/videos/733-accelerating-authentication-architecture-taking-passwordless-to-the-next-level) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) ## Related Articles - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [What is Software Engineering in the Age of AI?](https://www.wearedevelopers.com/magazine/640-what-is-software-engineering-in-the-age-of-ai) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Why Attend a Developer Event in 2026?](https://www.wearedevelopers.com/magazine/688-why-attend-a-developer-event-in-2026) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
