• Support technical investigations, root cause analysis, and solution development for complex operational and delivery challenges.
• Identify and manage technical risks, assumptions, constraints, dependencies, and architectural issues.
• Ensure designs address security, resilience, performance, supportability, scalability, and operational readiness.
• Provide technical assurance and design oversight during delivery.
• Evaluate new technologies, products, and integration approaches.
• Develop and maintain strategic architecture artefacts, including system context diagrams, component maps, integration maps, application landscapes, and end-to-end data flows.
• Establish architecture standards, design patterns, reference architectures, and governance processes.
• Contribute to continuous improvement of architecture practices, tools, methodologies, templates, and ways of working.
• Support knowledge transfer and maintain accurate architecture documentation throughout the service lifecycle.
• Act as a trusted technical advisor to programme leadership, delivery teams, and stakeholders.
• Promote collaboration between Indra, TfL suppliers, and engineering teams.
• Ensure architecture practice, standards, and governance frameworks are established and adopted.

Requirements

• Bachelor's degree in Computer Science, Information Technology, Engineering, or a related discipline (or equivalent experience).
• Significant experience delivering solution architecture for complex, large-scale technology platforms and business-critical systems.
• Proven experience producing high-quality architecture artefacts, including solution designs, architecture diagrams, interface specifications, and technical design documentation.
• Strong understanding of enterprise architecture principles, solution architecture methodologies, and architectural governance frameworks.
• Experience designing complex system integrations across applications, infrastructure, networks, cloud services, and third-party platforms.
• Experience working within highly available, business-critical, and operationally sensitive environments.
• Strong understanding of software development lifecycles, DevOps practices, and modern engineering delivery methodologies.
• Experience working in complex multi-supplier environments, coordinating architectural activities across several delivery partners.
• Ability to translate business requirements and technical constraints into practical, supportable, and deliverable solutions.
• Experience presenting solution designs and technical recommendations to architecture review boards, governance forums, and senior stakeholders.
• Strong understanding of security, resilience, scalability, performance, supportability, and operational readiness considerations.
• Experience producing architecture deliverables using industry-standard architecture modelling and documentation tools.
• Strong knowledge of systems integration patterns, APIs, messaging technologies, and data exchange mechanisms.
• Experience supporting technical delivery teams throughout implementation, testing, deployment, and operational transition.
• Excellent stakeholder management skills, with the ability to engage effectively with business, engineering, operational, and supplier organisations.
• Strong analytical and problem-solving skills, with the ability to identify risks, dependencies, and architectural impacts across complex systems.
• Experience maintaining strategic architecture artefacts, including system context diagrams, component maps, integration landscapes, and end-to-end data flows.
• Experience contributing to the development of architecture standards, design patterns, governance processes, and architecture best practices.
• Strong written and verbal communication skills, with the ability to communicate effectively with both highly technical teams and executive stakeholders.
• Experience within transport, payments, ticketing, revenue collection, or other highly regulated environments would be advantageous.
• Brings clarity and structure to complex technical and organisational challenges.
• Demonstrates sound technical judgement and pragmatic decision-making.
• Able to balance strategic thinking with hands-on solution design.
• Naturally collaborates across organisational, supplier, and technical boundaries.
• Comfortable challenging assumptions while building consensus among stakeholders.
• Focuses on delivering business outcomes rather than individual technical solutions.
• Influences decisions through expertise, credibility, and collaboration rather than formal authority.
• Takes ownership of architectural quality and technical integrity throughout the delivery lifecycle.
