Cloud Software Architect: API & Integration Leader

ENGIE Group; Milano; Presencial; EUR 42.000 - 49.000; Jornada completa

Descripción de la vacante

ENGIE Italia in Milan seeks a Cloud Software Architect to act as the internal technical authority, guiding integration across SaaS platforms and external partners.

You will define API contracts, govern vendors, and prototype glue code to bridge systems, while upholding security-by-design and enterprise patterns.

The role focuses on transforming heterogeneous systems into a cohesive architecture, collaborating with business and technology stakeholders across ENGIE.

Formación

• A degree in a relevant field (e.g., Computer Science, Engineering)
• Experience in the technical management of external vendors and in reviewing technical documentation produced by third parties.
• Proven experience of 3+ years in a Software Engineer role.
• Deep knowledge of microservices architecture, API Gateways, enterprise integration patterns, and security protocols.
• Ability to communicate authoritatively with both technical and non-technical stakeholders. You must be able to technically challenge a vendor and, at the same time, explain complex concepts to the business.
• Previous experience within the Energy & Utilities sector is a strong advantage.
• Solid and recent hands‑on development skills (e.g., in Python, Node.js, Java, or C#). The ideal candidate has not left coding behind, but instead uses it as a strategic tool to automate, prototype, and solve complex integration challenges.
• Hands‑on experience designing and consuming RESTful APIs and/or event-driven systems (e.g., Kafka).

Responsabilidades

• Technical Governance of Vendors: Analyze and validate the technical solution proposals from external partners. Ensure their designs are robust, scalable, and aligned with our strategies.
• API & Integration Strategy Definition: Design and document the company's API strategy. Define the interface contracts (API contracts), security standards (e.g., OAuth2), and protocols that all systems, internal and external, must comply with.
• Architectural Review Board: Act as the primary technical reviewer and approver for all new integrations and architectural changes proposed by the different teams.
• Tactical Development & Prototyping: Develop and maintain glue code components to facilitate integration or bridge functional gaps not covered by vendors. Build PoCs and prototypes to validate new approaches.
• Cybersecurity Oversight: Ensure that all integration solutions adhere to the company’s cybersecurity policies and best practices. Collaborate with security teams to identify risks, enforce security-by-design principles, and guarantee data protection across all systems.
