Role purpose:
Accountable for defining end to end solutions on assigned projects, documenting the solution in a Solution Architecture Document and taking the solution through the LSEG governance
processes. The role will also provide ongoing architectural guidance to the project through its
lifecycle.
Most projects will be focused around applications from one network architectures that needs to be accessed by users from another network architecture (aka cross company access). This will involve:

working with Infrastructure and Cloud Architects to understand how these new users will access the application e.g. route through Internet, use VDI solution etc. The lead Solution Architect will also need to work with other technical architects on the user journey for accessing these cross-company systems e.g. how to flow these new users into the system and manage permissions (e.g. leveraging existing JML processes)
Analyse and document the data flows in and out of the system and identify how they should flow when onboarding the new cross-company users (e.g. Impact of other downstream systems i.e. does data need to flow to an additional application and if so how is the output achieved to that system without impact existing integrations).

Key Responsibilities:

Work with Business Stakeholders, Product Owner, Business Analysts to understand functional and non-functional requirements and interact with other cross-functional teams
To be the lead architect to work with other architects to define the end-to-end solution & design covering all involved systems, data, integration, security and non-functional requirements
Identify architecture exceptions during definitions of target and transitional architectures
Follow governance processes agreed with CT Architecture Team - adherence to defined principles, policies, technology, information and process standards
Produce and maintain architecture documentation including Solution Architecture Document, Data Flow Diagram, Integrated Architecture diagram etc
Review solution individually with key non functional stakeholders e.g. Security, Privacy etc
Present solution in various forums (like Design Integrity Forum, Architecture Committee, Architecture Review Board) and with different teams like Security, Privacy.
Help project team to size & estimate project implementation and identify resources and skillset needed for delivery of solution
Ensure the proposed solution aligns with the business outcome
Ensures all solutions follow Corporate Technology and enterprise solution standards,
