Colt provides network, voice and data centre services to thousands of businesses around the world, allowing them to focus on delivering their business goals instead of the underlying infrastructure.

Why we need this role

This role is central to shaping Colt’s enterprise architecture strategy, with a strong emphasis on OSS technologies and core networking. As a key architectural leader, you will drive innovation and ensure that our technology landscape remains fully aligned with business goals and future-state capabilities.

You will lead a team of talented architects, collaborate with cross-functional stakeholders, and define the strategic direction and roadmap that support transformation initiatives across the business. Your deep understanding of OSS platforms, combined with your ability to balance strategic vision and hands-on technical insight, will be critical in delivering scalable and forward-thinking solutions.

• Scan for major disruptive technology and nontechnology trends (trendspotting) that affect business.
• Contextualize technology trends based on social, economic, political and other nontechnology trends.
• Identify technology-enabled innovation opportunities that enable business strategy and deliver expected business outcomes.

Plan and Manage the IT Portfolio

• Work closely with the (PMO) project management office to ensure the execution of plans corresponds with the promised outcomes throughout the project or product lifecycle.
• Present gap analysis and/or IT investment roadmaps that reflect the status of the existing IT estate, namely, its ability to contribute to future-state business capabilities around technological platforms.
• Lead analysis of the IT environment to detect critical deficiencies and recommend solutions for improvement.
• Lead the development of an implementation plan for the enterprise architecture based on business requirements and the varying IT strategies for project-driven or product-driven delivery teams.
• Collaborate with infrastructure, security, data and business process teams to ensure consistency with the enterprise architecture, as well as to identify when it is necessary to modify the enterprise architecture.

Orchestrate the Delivery of Business Outcomes

• Work with business leaders to identify key drivers and targeted business outcomes to derive useful business context.
• Lead analysis of the business’ future-state capabilities and future vs current IT environment to detect critical deficiencies and recommend solutions for improvement to drive the business forward.
• Ensure the core EA team works closely with extended EA team members across the organization.
• Ensure the role of EA in the project and product governance setting is one of guidance, advice and oversight.
• Oversee the documentation of all architecture design and analysis work.

Develop the EA Practice

• Create reference architectures focused on detailed integrations, major systems and dependencies between business and IT.
• Create architectural designs to guide and contextualize solution development across products, services, projects and systems (including applications, technologies, processes and information).
• Promote the business value of EA as an enabler of strategy formulation, and as support for technology innovation, which drives the organization’s top and bottom lines.
• Contribute to the maturing of the enterprise architecture practice into a centre of excellence.
• Plan and manage a talent pool of architects to help deliver the goals, objectives and outcomes of the organization.
• Assist in building/maintaining a skills inventory, and manage a plan to close the skills gap for EA team members which identifies trainings/coaching required to help them develop and progress in their careers.
• Participate in industry forums to represent our business and to harness standardisation which will support our business

Build and Maintain Relationships

• Provide consultative advice to business leaders and organizational stakeholders with actionable recommendations to make investment decisions about the next business and operating model of their organization, using technology to make that change happen.
• Lead and facilitate interaction with business leaders, product managers and product owners in a business-driven conversation over the risks and implications of product decisions.
