About Fuelius
Fuelius is a digital transformation consultancy and Elite HubSpot Partner, trusted by mid-market and enterprise businesses to lead some of the most complex CRM change programmes in the UK.
We specialise in helping organisations rip out legacy CRM platforms such as Salesforce and Dynamics, and replace fragmented, siloed tech stacks with scalable, connected systems. Our focus is on delivering commercial outcomes through operational clarity, RevOps strategy, and best-in-class CRM architecture.
As our engagements become more technically complex, we’re hiring a Solution Architect to lead the architecture and design of integrated solutions across multiple systems — ensuring the right blueprint is in place before delivery begins.
The Role
This is a permanent, full-time position for a senior Solution Architect with deep experience in post-sale system design, systems integration, and digital change. You’ll be responsible for leading discovery and defining the technical architecture for clients undergoing major commercial and platform transformation.
While our core delivery platform is HubSpot, every engagement involves designing integrations with a broader tech stack — including SaaS tools, proprietary systems, and legacy platforms. Your focus will be on mapping processes, defining data flows, and ensuring technical integrity across the end-to-end solution.
This role is primarily post-sale, but you’ll also support pre-sales scoping on complex projects — particularly where architecture, data migration, or integration work significantly shapes the scope.
This is not a product specialist or delivery role. It’s a consultative position for someone who thrives on leading technical conversations, translating ambiguity into architecture, and helping businesses move confidently through complex change.
Ideal candidates will come from a Salesforce partner, enterprise consultancy, or systems integrator background, with a strong understanding of what good architecture looks like across multi-system environments.
Key Responsibilities
* Lead post-sale discovery workshops with commercial and technical stakeholders
* Map data structures, integrations, and system interactions across CRM and the wider tech stack
* Define solution architecture for CRM and commercial transformation programmes
* Produce clear, actionable documentation that guides delivery teams and client decision-makers
* Translate business needs into technical requirements and system design
* Collaborate closely with delivery and consulting teams to ensure architectural fidelity
* Support pre-sales architecture scoping on larger or more complex deals
* Help shape Fuelius’ approach to system architecture and change management best practice
What We’re Looking For
* Strong experience in a Solution Architect or equivalent role, ideally from a Salesforce partner, enterprise consultancy, or integration-focused environment
* Demonstrated ability to design and document scalable, multi-system architecture across commercial and operational platforms
* CRM re-platforming experience is highly valued, but we’re equally open to candidates with background in adjacent systems such as ERP, finance, or operational tech, particularly where integration and change management were involved
* Skilled in system design concepts, including data modelling, APIs, middleware orchestration, synchronisation logic, and governance
* Comfortable producing clear artefacts and documentation using tools such as Lucidchart, Miro, or Draw.io
* Familiar with common SaaS ecosystems – not just CRM, but also tools in the marketing, operations, and finance space, and how they interconnect
* Confident leading discussions with senior stakeholders, with the ability to translate business needs into structured technical architecture
* A structured, consultative communicator, with strong commercial awareness and a delivery-conscious mindset
* You won’t be expected to execute the technical work directly, but you’ll be central to its success – working alongside a team of engineers, CRM consultants, data analysts, and project managers to ensure alignment, clarity, and technical integrity from day one
