We are looking for a Senior Solution Architect to act as the technical bridge between client and market requirements and our Development & Integration delivery teams.

Positioned at the heart of execution, you ensure that proposed solutions are architected, built, and integrated effectively, safeguarding quality, consistency, scalability, and long-term maintainability.

You provide technical credibility throughout the sales cycle and translate customer needs and commercial commitments into realistic, sustainable solutions that our delivery teams can successfully implement.

Key Responsibilities

Bid & Proposal Support: Lead technical responses to RFPs, RFIs, and tenders, including solution design, technical documentation, architecture diagrams, effort estimation, and risk identification. Ensure a clear and well-documented handover of won opportunities to the Development & Integration teams, preserving the technical intent and commitments made to the client.
Solution Definition: Take ownership of the solution architecture from bid handover through delivery, ensuring that the solution delivered remains aligned with agreed client requirements.
Feasibility & Estimation: Assess the technical feasibility of proposed solutions in collaboration with delivery teams, ensuring that scope, cost, timelines, and technical assumptions are realistic.
Solution Architecture: Design end-to-end solution architectures across applications, integrations, data, and infrastructure that are technically sound, cost-effective, scalable, and aligned with enterprise standards.
Integration Architecture: Design robust integration solutions using APIs, middleware, event-driven patterns, and data flows to connect client systems, internal platforms, and third-party services.
Delivery Governance: Define and promote architecture standards, design patterns, and technical guardrails across development and integration projects.
Technical Leadership: Guide development squads and integration teams on architecture decisions and facilitate design and architecture reviews throughout the project lifecycle.
Risk & Quality: Identify technical risks early, recommend mitigation strategies, and safeguard non-functional requirements including performance, security, scalability, and maintainability.
Vendor & Tooling: Contribute to the evaluation and selection of integration platforms, middleware, and development tooling in line with enterprise architecture standards.
Cross-Project Consistency: Promote architectural consistency, reusable patterns, and knowledge sharing across multiple development and integration projects.
Client Technical Relationship: Act as a trusted technical point of contact for clients during delivery, supporting discussions around architecture, scope, technical decisions, and change requests.
