Job description

Within the EMEA Development Centre (EDC), the Electrics and Controls department is responsible for the development of connected solutions across Daikin’s product portfolio, including embedded systems, mobile applications, and cloud platforms.

Our cloud ecosystem (including Onecta and related services) plays a central role in enabling smart, connected HVAC solutions, integrating devices, installers, partners, and digital services into a scalable and future-proof platform.

Your Role

As a Cloud Solution Architect, you will be responsible for designing and evolving the architecture of our IoT cloud platform, ensuring it remains scalable, secure, and aligned with evolving business and regulatory needs.

You act as a central technical authority, bridging product teams, development teams, and external partners, and ensuring end-to-end architectural consistency across our ecosystem.

You will play a key role in continuously improving the Onecta platform architecture, adapting it to new use cases such as integrations, APIs, data-driven services, and regulatory requirements.

Key Responsibilities

Architecture & technical leadership

• Define, document, and maintain the end-to-end architecture of our IoT cloud platform (device → cloud → apps → integrations)
• Translate business needs into scalable, robust, and future-proof technical architectures
• Ensure alignment across cloud services, APIs, mobile apps, and device communication layers
• Drive architectural decisions balancing performance, cost, scalability, and reliability
• Support the evolution of the platform towards:
• API-first and integration-friendly architectures
• Data-driven services and analytics use cases
• Multi-application and multi-stakeholder ecosystems (end-users, installers, partners)
• Identify gaps, technical debt, and improvement opportunities in the current architecture
• Validate architectural choices through proof-of-concepts and technical evaluations

Security, compliance & reliability

• Ensure security-by-design principles are embedded in the architecture
• Take into account regulatory requirements (e.g. CRA, NIS2) and operational constraints
• Design with observability, maintainability, and operational supportability in mind
• Collaborate with security and operations roles to ensure production readiness
• Work closely with development teams, product owners, and other architects to ensure implementation aligns with architecture
• Act as a technical counterpart towards external partners and suppliers
• Support and guide teams in making consistent architectural decisions
• Facilitate architecture reviews and cross-team alignment

Operational awareness

• Stay connected to real-world platform behavior (incidents, performance issues, operational feedback)
• Ensure architecture decisions consider run-time implications and support processes
• Contribute to improving platform stability and operational efficiency

Your Profile

Experience & background

• Master’s degree in Computer Science, Engineering, or equivalent
• Experience in cloud architecture or software architecture (IoT experience is a strong asset)
• Solid understanding of distributed systems and microservice-based architectures
• Experience with at least one major cloud platform (preferably AWS)

Technical knowledge

You bring experience with modern cloud-native and IoT architectures, including:

• Strong understanding of:
• API design and integration patterns (REST, OAuth2, API gateways)
• Event-driven architectures and asynchronous communication
• Designing scalable and highly available distributed systems
• Experience with technologies and patterns such as:
• IoT & communication: MQTT-based communication, IoT platforms (e.g. AWS IoT Core or equivalent)
• Compute & backend: serverless architectures and/or containerized services
• Data & storage: NoSQL databases and event streaming systems
• API & integration: API gateways (e.g. Kong or similar) and microservice communication patterns
• DevOps & automation: modern CI/CD pipelines and Infrastructure-as-Code (e.g. Terraform or similar)
• Familiarity with:
• Observability (logging, monitoring, tracing)
• Cloud security concepts (IAM, secure APIs, network isolation)
