Infrastructure System Architect ICT

Address Interxion Headquarters
Location Amsterdam

The Interxion ICT Systems Architect interfaces with multiple stakeholders in an organization in order to understand the various levels of requirements, the domain, the viable technologies, and anticipated development. The work includes determining multiple design alternatives, assessing such alternatives based on all identified constraints (such as cost, schedule, usability, reliability, maintainability, availability, and so on), and selecting and testing the most suitable options for further usage. The output of such work sets the core properties of ICT systems, and those that are hardest to change later.

The Infrastructure System Architect ICT reports directly to the Manager Infrastructure ICT

The Systems and Infrastructure Architect is:

  • A solution provider, functioning as an expert in providing agile, cost-effective, IT Infrastructure solutions and coordinating service delivery;
  • A specialist adviser, providing advice to management on establishing secure and reliable IT systems and best practices;

As a Systems Architect you perform ICT system engineering activities required to develop solutions and products that satisfy the requirements and needs of Interxion ICT. You work within the ICT teams in close cooperation with Management and are responsible for working out, stabilizing and maintaining the ICT architecture and the environment. The approach you apply, is based on agile and lean ICT engineering principles.

The main system activities you will perform are:

  • Analysis of stakeholder and customer’s needs
  • Create and maintain a technology roadmap
  • Establish the architecture through trade-offs between stakeholders’ expectations, in compliance with standardization and reuse policies, technology roadmap and business strategy
  • Evaluate and test the design, behavior, interactions, stability and performance
  • Provide computing, communications and security infrastructure design solutions
  • Conduct technical evaluations and proofs-of-concept to evaluate software and hardware products from external vendors and report on the same as a technical expert and advisor
  • Confirm that the requirements with which the solution has been designed are fulfilled
  • Demonstrate that the solution satisfies the operational needs
