Back to Job SearchThe team you'll be working with:
We’re hiring experienced, pragmatic and collaborative Solution Architects to shape and deliver national-scale digital, data and technology services across UK government. You’ll work with multi-disciplinary agile teams, make smart architectural decisions, and help our customers deliver secure, reliable and user-centred services in the cloud.
While we work polyglot, this role leans .NET/C# to support upcoming programmes.
If you’ve delivered systems for organisations such as the Home Office, Ministry of Justice or Ministry of Defence, fantastic; we also welcome candidates with transferable experience from complex, regulated environments
What you'll be doing:
You may embed within an agile team or lead across several squads. You will:
- Provide hands-on technical leadership to design and deliver secure, resilient solutions.
- Shape the architecture for new products and programmes, selecting fit-for-purpose approaches and technologies.
- Lead solution design across domains (applications, data, integration, cloud, security), creating clear roadmaps and decision records.
- Balance user needs, value, cost and risk with product, delivery and engineering peers.
- Communicate complex topics clearly, from the C-suite to engineers, and build trusted relationships with senior stakeholders.
- Guide engineering practices (CI/CD, testability, operability, observability) to reduce risk and increase delivery velocity.
- Contribute to bids and estimates, aligning solutions to public sector standards and constraints.
- Champion governance and assurance aligned to GDS, NCSC guidance and the Technology Code of Practice (where applicable).
What experience you'll bring:
We care about your approach as much as your toolkit. You:
- Think in systems, design for change and make evidence-based trade-offs.
- Are comfortable moving between strategy and hands-on detail.
- Excel in stakeholder engagement and management across policy, operations and technology.
- Collaborate openly in multi-supplier environments.
- Keep users, security and operability front and centre, and write things down (standards, ADRs, risks, diagrams).
Skills & experience we value
You don’t need everything here; if you have most of it (or strong potential to learn), we’d love to hear from you.
National-scale public services
- Experience delivering national scale systems and services, ideally with departments such as the Home Office, MoJ or MoD.
- Broad expertise across integration and messaging, digital services, case management, data integration, with up-to-date awareness of emerging approaches.
Cloud & platform
- Strong knowledge of cloud-based services and cloud-native solutions on at least one major platform (Azure preferred; AWS/GCP also valued).
- Common services: containers/Kubernetes/OpenShift, serverless (e.g., Azure Functions), networking, identity, storage, and IaC; automation and cost optimisation.
Applications & integration (.NET-focused)
- Designing modern application architectures: microservices, event-driven and API-led.
- .NET/C#, ASP.NET Core, Web APIs, gRPC; API management; messaging/streaming (e.g., Kafka, Service Bus, Event Hubs); contracts and documentation (OpenAPI/Swagger).
- Familiarity with front-end integration patterns and modern SPAs (e.g., React) is a bonus.
Data & stores
- Selecting appropriate persistence: relational (e.g., SQL Server, PostgreSQL), NoSQL (e.g., Cosmos DB, DynamoDB), caching (e.g., Redis).
- Data integration, quality, lineage and privacy-by-design.
Engineering & DevOps
- CI/CD (Azure DevOps, GitHub Actions or GitLab), Git, automated testing, security scanning, containers and infrastructure as code.
- Observability: logging, metrics, tracing, SLO/SLA thinking; designing for operability and support.
Security & assurance
- Delivering solutions with strict security controls, including environments where external security assurance is mandated.
- Building security into designs (threat modelling, identity and access, secrets management, encryption in transit/at rest).
Methods & communication
- Clear modelling and communication (C4/UML), option analysis and trade-off records.
- Creating architecture roadmaps and contributing to business cases.
Nice to have
- Experience with GDS phases (Discovery to Live) and service assessments.
- Domain-driven design, event sourcing, legacy modernisation.
- Sustainability and FinOps in the cloud.
- Certifications (e.g., Azure/AWS/GCP Architect, TOGAF), helpful but not essential.
Qualifications & eligibility
- Significant experience designing and delivering complex, distributed systems (typically 5+ years in architecture or senior engineering).
- Strong understanding of the full software delivery lifecycle and agile methods.
- Must hold current SC or be SC-clearable (generally five years’ UK residency).
- A relevant degree is welcome but not required; equivalent professional experience is valued.
