Job description

Swansea, United Kingdom | Posted on 22/09/2026

Scrumconnect Consulting is a UK-based digital transformation consultancy delivering secure, scalable, and user-centred solutions across government and enterprise organisations. We specialise in agile delivery, cloud platforms, data, and modern engineering practices, helping clients build reliable services that meet high operational and compliance standards.

Overview

We are looking for a Senior Solution Architect to lead the design of technical solutions for a major UK government client, helping them solve problems and deliver value for citizens and the public sector.

You will work with multidisciplinary agile teams within a large, complex technical estate where long-standing core systems sit alongside modern cloud services. The work is a mix of new build, change to existing national systems, and integration between the two, with delivery dates often set externally rather than by the programme.

This is a strategic technical role in a structured, governed environment where architecture decisions, security and long-term maintainability directly affect service outcomes for millions of users. It suits someone who enjoys staying close to delivery teams rather than designing at a distance from them.

Key responsibilities

• Own the solution design for a complex service, including its dependencies on legacy components
• Design pragmatic migration and integration approaches between established core systems and modern cloud services
• Design and assure payment journeys end to end, including integration with banking and payment providers
• Produce high-level designs and solution briefs, and document decisions so squads can build with confidence
• Work with engineering squads through design reviews, backlog shaping and sprint planning so designs are clear before development starts
• Build relationships with senior stakeholders across the engagement, including client architecture and security functions
• Shape patterns and reference architectures, and take designs through governance and design assurance
• Frame complex problems and set out options clearly so the right delivery approach can be chosen

Required skills and experience

• Hands-on architecture experience with payment systems, covering Open Banking and payments
• Practical understanding of reconciliation, idempotency, locking, webhook reliability, failure handling and data integrity in high-volume transactional services
• Demonstrable experience architecting in mixed estates, integrating established platforms with cloud-native services
• Strong solution architecture experience across the full delivery life cycle (discovery, alpha, beta, live)
• Confident making and communicating architectural decisions using ADRs and trade-off analysis
• Turning ambiguous business and policy needs into clear technical direction
• Hands-on with at least one major cloud platform and modern integration patterns
• Creating designs collaboratively and iteratively with delivery squads, not in isolation
• Information security, data protection and threat modelling fundamentals
• Strong communication with both technical and non-technical audiences
• Experience delivering digital services in UK central government or regulated environments
• TOGAF, or AWS, Azure or GCP architecture certifications
• Familiarity with the Technology Code of Practice and GOV.UK Service Standard
