Job Description:

We are looking to recruit a Technical Architect for a leading technology consultancy. The initial focus of this role will be on the evolution of a complex, business-critical software platform. They are looking for an experienced Technical Architect to review the current architecture, assess key technical uncertainties, define the next level of solution design, and provide hands-on architectural guidance to development teams. This role would suit a Technical Architect with strong experience across service-oriented architecture, Java-based systems, APIs, data flows, integration patterns, non-functional requirements and technical design documentation. You will need to be comfortable working closely with engineering teams, understanding complex existing systems, and turning architectural ambiguity into clear, actionable recommendations.

Job Responsibility:

Review and assess the existing high-level architecture, including key components, services, interfaces and deployment approach
Analyse the current service-oriented architecture and identify strengths, gaps, risks and areas of emerging technical debt
Assess alignment with strategic objectives and non-functional requirements, including reliability, determinism, maintainability, scalability and resilience
Evaluate integration options across a hybrid architecture, including how existing Java-based applications interact with newer services
Assess inter-service communication needs and provide recommendations on messaging, message bus patterns, protocols and associated trade-offs
Analyse and document system data flows, including real-time data, configuration data, core operational data, processed data and metadata
Evaluate whether a graph layer or alternative integration pattern would provide value as a primary interface between services
Define appropriate standards for APIs, messaging frameworks, data models, configuration management and service testing
Produce clear architectural documentation, including logical diagrams, high-level designs, service interaction models and data flow diagrams
Record key architectural decisions and rationale
Work closely with development teams to ensure a shared understanding of the architecture and support incremental delivery
Provide technical guidance, challenge and direction to help create a scalable, adaptable and operationally resilient architecture

Requirements:

Proven experience as a Technical Architect, Solution Architect or Software Architect on complex software systems
Strong understanding of service-oriented architecture, distributed systems and integration patterns
Experience working with Java-based applications or Java-heavy technical environments
Strong knowledge of APIs, messaging, data models, configuration management and service communication
Ability to analyse complex existing systems and produce clear architectural recommendations
Experience documenting data flows, system interactions, logical architecture and technical design decisions
Strong understanding of non-functional requirements such as reliability, scalability, maintainability, resilience and performance
Experience working closely with software engineering teams in an Agile or iterative delivery environment
Strong stakeholder communication skills, with the ability to explain complex technical concepts clearly
Ability to work onsite in Didcot 5 days per week
Eligible for BPSS clearance

Nice to have:

Experience with message bus technologies, event-driven architecture or asynchronous communication patterns
Experience evaluating or implementing graph-based interfaces, graph schemas or related integration approaches
Experience with scientific, engineering, research, data acquisition, instrumentation or highly technical software environments
Experience defining API standards, service boundaries and architectural governance
Experience assessing technical debt and creating pragmatic architecture roadmaps
Familiarity with DevOps, CI/CD, automated testing and service deployment practices
