Job description

Job Summary:
GN Group is a leading company in advanced intelligent hearing solutions, and they are seeking a Cloud Developer for their GNOS platform. The role involves designing, building, and operating cloud-native services to support hearing care professionals and enhancing the overall user experience with GN's products.
Responsibilities:
• Design & Development (R&D focus)
• Implement cloud-native backend services and APIs for GNOS that directly support GN’s hearing products and R&D roadmaps.
• Translate product requirements and system designs into well-structured, maintainable cloud solutions with clear interfaces and versioned contracts.
• Contribute to a modular platform architecture that can be reused across product lines, markets, and channels (fitting, patient apps, professional portals, partner integrations).
• Cloud Infrastructure & Operations
• Contribute to infrastructure-as-code (e.g., ARM/Bicep/Terraform) and deployment patterns for GNOS services in Microsoft Azure.
• Help design and implement resilient, observable services (logging, tracing, metrics, alerts) aligned with product and platform SLAs/SLOs.
• Participate in operational support and incident analysis for R&D-owned cloud services, feeding learnings back into design and code.
• Quality, Safety & Security by Design
• Apply secure coding and privacy-aware design, adhering to GN’s R&D quality system and relevant standards for health/medical contexts where applicable.
• Work closely with R&D test engineers (including teams in Hyderabad/iRay and other locations) to ensure comprehensive test coverage (unit, integration, contract, performance).
• Support early defect discovery by integrating tests, static analysis, and security checks into CI/CD pipelines and by designing testable services and APIs.
• Cross-Disciplinary Collaboration
• Work in agile, product-focused R&D teams that include software engineers, testers, product owners, UX, and system architects.
• Participate in backlog refinement, estimation, and technical design discussions, balancing platform health with product delivery.
• Collaborate effectively with client application teams (e.g., fitting software, mobile apps, portals) so GNOS services meet their functional and non-functional needs.
• Continuous Improvement & Innovation
• Identify and help address technical debt in GNOS services, focusing on areas that unlock product innovation, performance, or reliability.
• Contribute to improving the R&D development environment, including CI/CD pipelines, observability, and use of tools like GitHub and GitHub Copilot.
• Stay current with cloud, platform, and health-tech trends and bring relevant ideas into the GNOS and R&D roadmaps.
Qualifications:
Required:
• Bachelor’s degree in computer science, Software Engineering, or a related field, or equivalent practical experience.
• 3–5 years of professional experience developing backend or platform services in production environments.
• Direct experience with at least one major cloud provider, such as Microsoft Azure, including services like API management, databases, messaging, identity, and containers.
• Proficient in programming with at least one backend language (for example, C#/.NET, Java, or Node.js/TypeScript).
• Experience designing and implementing RESTful APIs consumed by other R&D teams or external partners.
• Practical experience with CI/CD, automated testing, and Git-based workflows (GitHub or similar).
• Demonstrated focus on reliability, maintainability, and security in solution design and implementation.
Preferred:
• Experience with Azure services such as Azure App Service, AKS, Azure Functions, Azure API Management, Azure SQL/Cosmos DB, Service Bus/Event Grid.
• Experience with event-driven architectures or microservices in a product/R&D context.
• Familiarity with regulated environments (e.g., medical devices, health tech) or solid understanding of privacy and data protection requirements.
• Experience with observability tooling (e.g., Application Insights, Prometheus/Grafana, OpenTelemetry).
• Experience working in distributed R&D teams across multiple time zones.
• Familiarity with GitHub Actions, GitHub security features, and AI-based coding assistants such as GitHub Copilot.
