Role Summary

The Specialist Software Engineer (App & Cloud) is a senior technical expert responsible for the end-to-end design and development of cross-platform mobile applications and Azure-based cloud services supporting our IoT-connected HVAC products.

This role will lead architecture and implementation across mobile app, APIs, and cloud components, ensuring a seamless and reliable user experience from device onboarding to remote control, monitoring, and firmware update flows. The Specialist will act as a key technical leader, working closely with embedded, system, QA, and product teams, and mentoring other engineers.

Key Responsibilities

• Lead the architecture, design, and implementation of cross-platform mobile applications (e.g. Flutter / React Native / .NET MAUI) for iOS and Android.

• Own critical app features such as:

Device onboarding (BLE/Wi-Fi provisioning)

Remote control and monitoring of HVAC units

Energy usage visualization and notifications

Firmware update and maintenance flows

• Design and implement Azure cloud services and components, such as:

Azure App Service / Functions / Container Apps

Azure IoT Hub / Event Hub / Service Bus

Data storage (Cosmos DB, Blob Storage, SQL, etc.)

• Define and maintain secure, scalable RESTful APIs and/or GraphQL endpoints for mobile apps and partner integrations.

• Ensure reliable end-to-end communication between mobile apps, cloud platforms, and IoT devices (MQTT, HTTPS, WebSocket, etc.).

• Drive code quality: coding standards, code review, automated unit/UI tests, and CI/CD pipelines for both app and cloud components.

• Monitor and improve performance, reliability, and cost efficiency of cloud services (logging, metrics, alerting, autoscaling, cost optimization).

• Collaborate with embedded firmware teams to define data models, API contracts, and device behaviors for connected features.

• Work closely with UX/UI designers and product owners to turn requirements into user-friendly and robust app experiences.

• Support production incidents and field issues, performing root cause analysis and implementing long-term fixes.

• Apply security and privacy best practices (authentication/authorization, secure storage, encryption, protection of user and device data).

• Mentor junior and mid-level engineers in app and cloud technologies, design patterns, and best practices.

• Contribute to technology roadmaps and continuously evaluate new frameworks, tools, and Azure services suitable for our platform.

Qualifications & Experience

• Bachelor’s or Master’s degree in Computer Science, Computer Engineering, Software Engineering, or related field.

• Typically 7+ years of professional experience in software development, with solid experience in:

Mobile app development, and

Cloud-based backend development.

• Strong hands-on experience with at least one cross-platform mobile framework (e.g. Flutter, React Native, or .NET MAUI).

• Solid proficiency in relevant programming languages (e.g. Dart, TypeScript/JavaScript, C#, or similar).

• Proven experience designing and building RESTful APIs and integrating mobile apps with cloud backends.

• Practical experience with Microsoft Azure services in production (e.g. App Service, Functions, IoT Hub, Cosmos DB, Storage, Key Vault, API Management).

• Experience with CI/CD pipelines (Azure DevOps, GitHub Actions, or similar) for app and backend deployment.

• Familiarity with secure authentication/authorization (OAuth2/OIDC, JWT, Azure AD B2C, etc.).

• Experience working in an agile / Scrum environment with version control (Git) and modern development workflows.

• Good written and spoken English for collaboration with global teams and documentation.
