Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Technical Architect - **Company:** IMServ Europe Ltd - **Location:** Milton Keynes, UK - **Contract:** Permanent contract - **Skills:** .NET Framework, Application Programming Interfaces (APIs), Artificial Intelligence, Microsoft Azure, C Sharp (Programming Language), Software as a Service, Command-Query Responsibility Segregation (Software Development), Customer Data Management, Data Architecture, Data Infrastructure, Middleware, Reference Data, Azure Machine Learning, Web Applications, Retrieval-Augmented Generation, Large Language Models, Event Driven Architecture, Microsoft Fabric, AngularJS, Data Management - **Published:** September 16, 2026 - **Apply:** https://www.totaljobs.com/job/technical-architect/imserv-europe-limited-job107984338 ## About the Role * Significant experience as a technical or solutions architect on customer-facing SaaS platforms, spanning web applications, API tiers and data platforms. * Direct experience of multi-tenant SaaS architecture, ideally including a single-tenant to multi-tenant migration. * An engineering background on or near our stack: C#/.NET, Angular and Azure. * Experience of event-driven architecture and workflow or rules tooling: orchestration engines (Azure Durable Functions, Temporal, Camunda or similar), decision tables (DMN), message backbones and CQRS-style read models. * Practical, current knowledge of AI: LLMs, retrieval-augmented generation, agent patterns, and what it takes to run them safely over commercial customer data. * Knowledge of the wider Microsoft estate, ideally including Microsoft Fabric; hands-on Azure AI services desirable. * Energy or utilities domain knowledge desirable: metering, half-hourly settlement, MHHS, carbon reporting. Skills * Data architecture depth for high-volume time-series and reference data. * Able to work pragmatically in a smaller or scaling organisation, where sequencing matters more than frameworks. * Able to explain a trade-off to a non-technical executive as clearly as to an engineering team. * Sound commercial judgement on build-versus-buy and technology selection. ## Description The role will own the architecture of the Astral platform, including the governed data foundation, orchestration, rules and entitlement engine, integration layer, API tier, portal and partner front ends, and the AI layer. The role will also act as the design authority for all significant technical decisions across the product squads and own the technical roadmap from the current estate to the target state, working closely with the Head of Development. A key focus of this roadmap will be the transition from a single-tenant to a multi-tenant architecture., * Keep the current and target architecture documented, validated and understood across the department. * Review and approve significant technical decisions: patterns, technology choices, integration approaches and third-party services. * Define the API strategy: portal, analytics and data-feed APIs treated as products, with entitlement (who sees what, down to meter point, site and channel) enforced once at the tier. * Design the multi-utility data architecture: how metering, consumption, carbon, asset and CRM data flows from replaceable source systems through the integration layer (Microsoft Fabric and middleware) and is productised for operational and commercial use. * Design the rules and orchestration layer: an event backbone, an orchestration engine for job lifecycles, a decision engine driven by business-editable decision tables, and read models served through the APIs. Adopt proven engines rather than building bespoke ones and run advisory-only before automating actions. * Design the AI layer: retrieval over the data foundation, guardrails, and model and service selection, respecting entitlement throughout. * Lead build-versus-buy evaluations on total cost, time to value and lock-in risk. ## Related Videos - [Reference Architecture of AI in the Cloud](https://www.wearedevelopers.com/videos/1613-reference-architecture-of-ai-in-the-cloud) - [Fault Tolerance and Consistency at Scale: Harnessing the Power of Distributed SQL Databases](https://www.wearedevelopers.com/videos/1520-fault-tolerance-and-consistency-at-scale-harnessing-the-power-of-distributed-sql-databases) - [How to Stop Choosing JavaScript Frameworks and Start Living](https://www.wearedevelopers.com/videos/118-how-to-stop-choosing-javascript-frameworks-and-start-living) - [Developer’s Perspective: Overview of the Tezos Blockchain Ecosystem](https://www.wearedevelopers.com/videos/237-developer-s-perspective-overview-of-the-tezos-blockchain-ecosystem) - [Why make use of an integration platform in today's software developments and infrastructure?](https://www.wearedevelopers.com/videos/758-why-make-use-of-an-integration-platform-in-today-s-software-developments-and-infrastructure) - [Enjoying SQL data pipelines with dbt](https://www.wearedevelopers.com/videos/823-enjoying-sql-data-pipelines-with-dbt) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers)
