Solution Architect

The Solution Architect is responsible for the end-to-end design, development, and implementation of robust, scalable, and secure technology solutions that directly support organisational objectives. Acting as a strategic conduit between business stakeholders and technical teams, this role ensures that architectural integrity is maintained throughout the entire software development lifecycle.

You will be tasked with delivering technical designs of moderate risk and complexity, ensuring they remain coherent and responsive to evolving requirements. By challenging assumptions and identifying strategic opportunities, you will play a pivotal role in translating a high-level vision into actionable roadmaps.

Architectural Design & Strategy
● Create and maintain technical blueprints that balance innovation with architectural coherence, ensuring all designs are optimized through iterative feedback loops.
● Interpret organisational roadmaps to develop solution strategies that align with long-term digital goals.
● Proactively challenge requirements and underlying assumptions to ensure the most efficient and effective technical path is selected.

Governance, Risk & Assurance
● Identify, document, and mitigate architectural risks that impact multiple teams or domains, specifically focusing on solutions of medium risk and complexity.
● Ensure all solutions adhere to Government Digital Service Standards and the Technology Code of Practice, maintaining readiness for formal Digital Service Assessments.
● Apply established architectural principles, patterns, and constraints to all decision-making processes. Contribute to the continuous improvement of internal architectural governance frameworks.

Collaboration & Delivery
● Work as a key member of a blended, multidisciplinary Agile team, participating in sprint planning, peer reviews, and retrospective sessions.
● Communicate complex technical concepts effectively to both senior leadership and external customers, fostering consensus on critical design decisions.
● Maintain rigorous documentation standards, ensuring all architectural outputs are captured within official repositories, including Navy Digital Confluence, SharePoint, and GitHub.

Top 3 requirements:

1. Ability to produce architectural representations that enable different teams to have a shared understanding of problems throughout the life cycle.
2. Strong communication skills as you will need to communicate complicated, complex or risky architecture topics with technical and non-technical stakeholders.
3. Experience with tracking emerging issues, strategies, roadmaps, patterns and technologies over time to assess opportunities and risks to your work.
