Job description

Solution Architect

London | Hybrid | £80,000

We are looking for an ambitious Solution Architect to join the Technology function of a highly regarded organisation operating within the legal and professional services sector.

This is an excellent opportunity for someone who has developed their career from a strong software engineering or technical development background and has moved into Solution Architecture over the last few years.

You will work at the intersection of business and technology, helping to design practical, scalable and secure solutions across a complex enterprise application landscape. This is a hands-on architecture role where you will work closely with engineering, product, delivery and technology teams to turn business requirements into robust technical solutions.

The Role

As a Solution Architect, you will play a key role in designing and delivering technology solutions that meet business needs while aligning with wider architecture standards and principles.

You will work closely with Domain Architects, engineers, technical specialists and delivery teams, bridging the gap between high-level technology strategy and practical implementation.

This role would particularly suit someone with approximately 2-3 years' experience in Solution Architecture, Technical Architecture or a senior technical design role, supported by a previous career in software engineering or development.

Key Responsibilities

• Translate business requirements into clear and practical technical solution designs.
• Produce architecture documentation including High-Level Designs (HLDs), Low-Level Designs (LLDs), integration specifications and technical design documentation.
• Work closely with software engineering and delivery teams to guide implementation and resolve technical challenges.
• Design end-to-end integration solutions across a complex enterprise application landscape.
• Define API contracts, message schemas and integration patterns to enable reliable system connectivity.
• Design and document data flows, ensuring appropriate consideration of security, data protection and information classification.
• Participate in architecture reviews for projects and technology change.
• Evaluate technology options and contribute to build versus buy decisions.
• Support Proofs of Concept (POCs) and technical investigations to validate architectural approaches.
• Define and validate non-functional requirements, including performance, scalability, resilience, availability and security.
• Work collaboratively with Data, Platform, Security and Product specialists to ensure solutions are aligned across technology domains.
• Create and maintain architecture documentation, technical specifications and architectural decision records.
• Present solution designs and technical recommendations to relevant stakeholders and governance forums.
• Work with third-party technology vendors and partners to assess and integrate solutions.
• Share knowledge and support engineers and technical specialists in adopting good architecture and engineering practices.

Technology Environment

You will work across a modern enterprise technology landscape, with particular exposure to:

• Microsoft Azure
• Azure App Services
• Azure Functions
• Azure Service Bus
• Azure API Management (APIM)
• REST APIs and integration architecture
• Messaging and event-driven architectures
• SQL Server and relational databases
• Data integration and synchronisation patterns
• DevOps and CI/CD pipelines
• Enterprise applications and third-party SaaS platforms

Experience working with complex business applications, document management systems, CRM platforms, ERP systems or other enterprise applications would be beneficial.

Experience of applications used within the legal, professional services or other regulated industries would also be advantageous.

About You

We are keen to speak with candidates who have:

• Around 2-3 years' experience in Solution Architecture, Technical Architecture or a similar technical design role.
• A strong earlier background in software engineering, software development or technical delivery.
• Experience designing integrations across enterprise applications.
• Strong knowledge of API design, messaging patterns and system integration.
• Experience working with Microsoft Azure and cloud-native application services.
• A good understanding of security architecture principles and data protection.
• Experience with relational databases, ideally SQL Server.
• Knowledge of DevOps practices, CI/CD and modern software delivery approaches.
• A strong understanding of non-functional requirements including performance, scalability, resilience and security.
• Experience producing technical documentation and solution designs.
• The ability to communicate effectively with both technical and non-technical stakeholders.

Experience with enterprise architecture frameworks such as TOGAF, Agile delivery methodologies, or architecture tooling would be advantageous, but this is not a role that requires a long-established Enterprise Architect.

Why This Role?

This is a fantastic opportunity for an ambitious Solution Architect who wants to take the next step in their architecture career within a complex, technology-driven professional services environment.

You will gain exposure to a broad enterprise application landscape, work alongside experienced architects and technical specialists, and play a genuine role in shaping and delivering solutions across a growing and evolving technology function.

If you have a strong technical foundation, enjoy solving complex integration and architecture challenges, and are ready to build further on your Solution Architecture career, we'd love to hear from you.
