Desirable * Experience architecting law-enforcement, intelligence, or regulatory case-management platforms. * Familiarity with WSO2 API Gateway/IdAM, ClamAV or similar security tooling. * Experience architecting data-science/ML tooling (SageMaker) or search/analytics platforms in an analytical-toolset context. * Relevant security clearance, or the ability to obtain one. * TOGAF, AWS Certified Solutions Architect (Professional), or an equivalent architecture certification., * Degree in Computer Science, Software Engineering or a related field, or equivalent demonstrable experience. * TOGAF (or an equivalent enterprise/solution architecture framework) certification is desirable; AWS Certified Solutions Architect is also desirable. ## Description Solution & Technical Architecture * Act as the technical design authority for the platform, producing and maintaining high-level and detailed solution designs across its core service domains. * Define target-state architecture for the platform's mixed .NET Core, Python and JavaScript/TypeScript (Vue.js, React) estate, ensuring new solutions are consistent with agreed patterns and standards. * Design integration patterns across the containerisation (Docker), reverse-Proxy/API layer (OpenResty, Nginx) and infrastructure-as-code (Terraform) tooling. * Design and govern integration with identity, authentication and security platforms (LinOTP, RADIUS, WSO2 IdAM, WSO2 API Gateway, ClamAV), ensuring solutions meet authentication, authorisation and malware-scanning requirements. * Produce architecture decision records (ADRs), solution diagrams and non-functional requirement (NFR) specifications for significant changes. Technology Modernisation & Target-State Roadmap * Own the target-state architecture and modernisation roadmap for the platform, identifying and sequencing remediation of end-of-life or unsupported components (for example, the current Terraform estate). * Assess the long-term viability of Legacy application components - including the .NET WPF desktop application and the dual Front End framework footprint (Vue.js and React) - and produce architecture recommendations on consolidation, retirement or re-platforming. * Evaluate and recommend use of managed AWS services (SQS, DynamoDB, SageMaker, OpenSearch, FSx, WorkSpaces, ECR) against in-house build, applying AWS Well-Architected principles. * Maintain a technology radar/roadmap for the estate, flagging obsolescence and security risk to programme governance. ## Related Videos - [Building Well-Architected applications](https://www.wearedevelopers.com/videos/691-building-well-architected-applications) - [Post-Quantum Cryptography: Preparing for Q-Day](https://www.wearedevelopers.com/videos/100179-post-quantum-cryptography-preparing-for-q-day) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) - [We (don't) need a software architect!?!](https://www.wearedevelopers.com/videos/663-we-don-t-need-a-software-architect) - [Streaming AI Responses in Real-Time with SSE in Next.js & NestJS](https://www.wearedevelopers.com/videos/1630-streaming-ai-responses-in-real-time-with-sse-in-next-js-nestjs) ## Related Articles - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london)
