Principal Solution Architect

Join OneAdvanced

OneAdvanced serves customers who often have deeply embedded, on-premise or hosted systems that are integral to how they operate.

This is a senior, customer-facing architecture role that goes well beyond traditional pre-sales. You will act as the bridge between customer strategy, core business processes, technology design, and service delivery — working alongside sales teams to help organisations modernise their enterprise landscapes.

You will also play a meaningful role in how we approach this commercially — partnering with Revenue Enablement to shape the technical sales methodology we use across the business.

What You Will Do

Day to day

• Work closely with customers to understand their current-state systems, data flows, and key processes — and map these to the capabilities of our workflows/applications and platform services.
• Define integration and data flow strategies across internal and third-party systems, which may include ERP, HR, CRM, and risk and compliance platforms.
• Advise on master data management approaches with a platform-first mindset, reducing architectural complexity and technical debt.
• Assess customer data readiness for AI adoption — identifying quality, governance, and lineage gaps that need to be resolved before AI features can deliver meaningful value, and guiding customers through a pragmatic path to readiness.
• Help customers understand how AI and automation can be embedded within their workflows to improve decision-making and operational efficiency.
• Engage substantively with responsible AI and governance questions, particularly with buyers in regulated environments such as health, care, and government — covering explainability, auditability, bias, and data subject rights.
• Navigate sector-specific constraints — whether data residency and security requirements in health and care, procurement framework obligations in public sector, or operational integration demands in transport, logistics, and manufacturing — and design solutions that address these without compromising platform simplicity.
• Understand the outcome the customer is looking to achieve, and architect the solution to move them from their existing tech stack to IQ, the intelligent system of work for their given sector.
• Articulate how a move to OneAdvanced simplifies enterprise architecture — making the case clearly to both technical and non-technical stakeholders.
• Contribute to the development of our technical sales methodology in partnership with Revenue Enablement and the broader Solutions team.
• Subject matter expert for Bid responses around architecture, security and AI, working as part of a group of stakeholders to complete responses
• Partner closely with Sales, Product and Services to ensure proposed solutions are executable, scalable, and aligned to customer outcomes.
• Represent OneAdvanced at customer and industry events, sharing insight on data architecture, integration design, and digital transformation in enterprise software

What You Will Have

Please note, applicants must have the legal right to work in the UK at the time of application.

Technical depth

• Strong grounding in ERP architecture — data models, integration patterns, and business process dependencies. Comfortable with cloud platform design, multi-tenant SaaS, and modern security models.

Migration literacy

• Experience assessing legacy, on-premise, or hosted environments. Able to identify complexity, data integrity risk, and dependency chains — and translate these into a coherent transition approach.

Consultative instinct

• Skilled at discovery. Able to surface what is actually blocking a customer, not just what they say is blocking them. Confident challenging assumptions.

Commercial awareness

• Understands the deal context. Can build a compelling total cost of ownership case and recognise when technical risk is genuine versus when it is customer anxiety in disguise.

Methodology thinking

• Desirable - has contributed to or built technical sales playbooks — including qualification criteria and discovery documentation. Able to abstract patterns from deal experience and codify what good looks like.

Cross-functional influence

• Comfortable working laterally without authority. Influences sellers, enablement, and Solutions colleagues through credibility and clear reasoning rather than hierarchy.

Applied AI translation

• Able to move a customer from vague curiosity — or vague fear — about AI to a concrete, credible adoption roadmap. Understands how AI capabilities embed into existing workflows, not just what they are in theory. Conversant in responsible AI, data readiness, and governance requirements, particularly in regulated environments.

Sector expertise

• Desirable – experience working in the sectors we serve, and an understanding of some of the regulatory compliance our customer operate under.

Beyond the job spec

• You stay current on platform evolution, competitor positioning, and sector trends.
• You are methodical under pressure. You do not cut corners on rigour when a deal gets complex or a timeline compresses.
• You are honest with customers helping them to see where something is a genuine challenge, or help them overcome perceived challenges.
• You know that the biggest barrier to AI adoption in most organisations is not technology — it is data quality, governance, and trust. You can have that conversation without losing the room.

If you have spent your career sitting at the intersection of enterprise technology and the humans who rely on it — and you want a role where your architecture thinking directly shapes both customer outcomes and how a business sells — we would like to hear from you
