Job Description
Senior Software Engineer, .Net
Mindera
We are building a world-class team to evolve a high-performance, event-driven ecosystem. We don’t just write code; we architect solutions that handle complex financial and data workflows. As a Senior Software Engineer, you will be at the forefront of our migration to .NET 8 and the integration of Generative AI (LLMs) into our core product. This is a role for an engineer who understands that a system is only as strong as its weakest link—whether that’s a race condition in an SQS queue or a poorly optimized Redis cache. You will work in a modern stack, moving away from legacy infrastructure towards a cloud-native, AI-augmented future. National and international expected traveling time: 0%-15% estimated.
Job Requirements
- What you will be doing:**
- High-Scale Development: Design and implement robust microservices using .NET 8, focusing on performance, scalability, and clean architecture.
- Event-Driven Architecture: Build and refine asynchronous workflows using AWS SNS/SQS, ensuring data consistency and system resilience.
- AI Integration: Lead the technical implementation of LLMs into our applications, bridging the gap between .NET backends and Python-based AI logic.
- Data Engineering: Collaborate on the design of high-throughput data pipelines using AWS Data Firehose and Data Streams for real-time processing.
- Quality & Testing: Maintain a high bar for code quality using xUnit and WireMock, ensuring that our transition to new services is seamless and regression-free.
- Infrastructure Collaboration: Work closely with SREs to deploy services via GitHub Actions and manage resources through Terraform.
- Modern Tooling: Leverage GitHub Copilot and ChatGPT to accelerate delivery while maintaining critical oversight of code security and efficiency.
- Expertise we are looking for:**
- .NET Mastery: Deep expertise in C# and .NET Core / .NET 8. You must know the framework's internals, not just the syntax.
- AWS Native Experience: Practical experience building applications that leverage SNS, SQS, S3, and ECS.
- Distributed Systems: Strong understanding of Event-Driven Architecture and patterns (Pub/Sub, Competing Consumers, Idempotency).
- Caching Excellence: Proven experience with Redis or Valkey for state management and performance optimization.
- AI/ML Curiosity: Experience or strong interest in working with LLMs and Python. If you’ve built RAG systems or integrated OpenAI/Anthropic APIs, you are ahead of the curve.
- Testing Rigor: A "test-first" mindset. If you don't value unit and integration testing, you won't survive our deployment cycle.
- DevOps Awareness: Familiarity with Docker, GitHub Actions, and Terraform. You don't need to be an SRE, but you must speak their language.
Benefits
- The Things We Really Care About:**
- Permanent contract
- Unlimited PTO
- Flexible working hours
- Training & conferences, create your own training plan
- Work with large scale systems powering global businesses**
- Other Good Things:**
- Choose Laptop & Peripherals that best suit your needs
- Hotspot with unlimited usage (PT), for work or Netflix ;)
- We have amazing offices in Porto, Aveiro, and Coimbra if you want to physically connect with minders. Remote from Portugal is also an option. Remote from other Countries will depend on your current location and Projects
- At the offices, we have a wide range of snacks to keep you fed and healthy
- Partnerships with local businesses
