Job Specifications

Mosaic Island are looking for an experienced Solution Architect to work on a client experienced in the Web Applications domain.

We require a Senior Solution Architect to take over architectural leadership of the customer-facing web application stream within the Fusion X platform. The role is not hands-on development, but a specialist, consultant-level SA with strong Front End web application architecture experience who can quickly pick up existing decisions and in-flight work, embed with delivery teams, and provide clear architectural direction.

The emphasis is on continuity, momentum, and confident architectural leadership in a complex, established environment, rather than defining a new greenfield solution.
Scope of Responsibilities:
Architectural Leadership
Own and drive the web app architectural approach.
Provide a coherent driving view for customer web applications.
Ensure continuity with existing architectural decisions and artefacts.
Delivery Engagement
Embed with delivery teams to influence and guide implementation.
Work closely with EPAM delivery to provide architectural direction and oversight.
Act as the primary architectural escalation and decision point for the web app stream.
Core Skills and Experience
Strong web application architecture experience, with a focus on customer-facing, Front End web apps.
Ability to operate credibly across architecture and engineering discussions.
Experience inheriting and progressing an existing architecture rather than resetting it.
Exclusions
Not a hands-on developer role.
Not a generic Solution Architect
This is an Inside IR35/Via Umbrella opportunity which is a hybrid role from home and some days in the Yeovil office per week.
