• Develop and maintain APIs and backend services for high-throughput, real-time systems
• Integrate AI services and LLM-based capabilities into existing infrastructure, ensuring reliability, performance, and measurable business value
• Design and optimize workflows involving AI-driven content extraction, transformation, and validation
• Integrate with external providers, AWS infrastructure, and messaging systems
• Ensure robustness of distributed workflows, including proper error handling, retries, idempotency, and observability
• Make architectural decisions and contribute to long-term technical strategy
• Review and improve code quality, performance, and maintainability while minimizing technical debt
• Collaborate closely with product and leadership to align technical solutions with business objectives
• Evaluate the effectiveness of AI-enhanced pipelines and continuously optimize scalability and operational stability
• Document architectural decisions and technical trade-offs in a clear and structured manner

Requirements

• 5+ years of professional.NET / C# development experience

• Solid experience with both SQL (SQL Server) and NoSQL (MongoDB) databases
• API design and development experience
• Strong command of async/await, threading, and resource management
• Distributed systems awareness: error handling, retries, idempotency, message queues
• A strong quality-oriented approach, with attention to edge cases, system reliability, and potential failure scenarios
• A product-driven mindset, focused on delivering meaningful impact rather than simply completing tasks, and comfortable operating with a high degree of autonomy
• The ability to evaluate and validate the effectiveness of implemented solutions, collaborating with product and leadership to ensure alignment with business objectives
• Sound judgment in balancing independent decision-making with timely stakeholder alignment, supported by clear and structured documentation of architectural and technical choices.
• Excellent communication: you ask good questions, listen carefully, and surface blockers early

Nice to Have

• Experience integrating with LLMs or AI APIs, including prompt design and management
• Background in web scraping, data extraction, or document processing pipelines
• Experience with news aggregation, media data, or financial information services
• Familiarity with Python or C# for data processing workflows
• Experience with containerisation (Docker, Kubernetes)

We Offer

• Competitive salary
