TfL exists to move London forward safely, inclusively, and sustainably. London’s success depends on colleagues continuously improving and innovating to make moving around our city more safe, inclusive, and sustainable. We have the opportunity to improve people’s lives and help our city navigate the future more than almost any other transport body in the world.

To do this we have to navigate an ever-changing environment. Technology is evolving at breakneck speed. When and how customers use our network is shifting. The climate emergency is accelerating. TfL needs Solution Architects to work on projects that cover all of its responsibilities: public transport, roads, walking, cycling, real estate, asset management, regulation, and enforcement.

We are looking for solution architects who are passionate about working for TfL, have the business and technical skills to help deliver complex solutions across multiple technologies, business units and technical teams. Interpersonal skills are as important as your technical capabilities. You must be a critical thinker, with the ability to research and provide summarised results. You must be comfortable presenting your recommendations to all role levels within impacted business and technical teams.

You must be able to prioritise your work, meet deadlines, anticipate, and resolve problems.

The role requires you to be in the office 50% of your time. The technology and development teams are based in North Greenwich.

You will be responsible for the creation of project level architecture designs for solutions that are built in-house or are delivered by partners. In creating the solution architecture, you will build consensus and gain approval from impacted business and technical teams. You will support project teams through delivery to ensure the desired outcomes are achieved and design changes are fully considered, agreed, and approved.

• You will ensure that the project vision, scope, and desired outcomes are properly defined and will meet the needs of the business.
• Understand organisational objectives and external drivers. For example, legislation or industry compliance.
• Lead the end-to-end solution architecture for projects involving high-volume mission critical revenue generating systems.
• Work within business and technical constraints.
• Work with colleagues in other technical teams to ensure principles and best practice are applied.
• Ensure that functional and non-functional requirements are fit for purpose. Ensure they align with project scope, vision, and criticality of the service.
• Stay up to date with technology trends and approaches.
• Analyse and present solution options to business and technical stakeholders. For example, develop build verses buy options.
• Work with technical teams to build costs and delivery estimates.
• Manage risks, decisions, and assumptions in a transparent way.
• Design and document high-level and low-level designs aligned with TfL enterprise architecture principles. Ensure their approval through formal governance.
• Communicate and work collaboratively with business and technical stakeholders. Help teams to understand technical and business perspectives in order to build consensus.
• Support project teams through delivery to ensure the desired outcomes are achieved and design changes are fully considered, agreed, and approved.
