Join OneAdvanced
At OneAdvanced, we're building technology that powers the world of work.
We're looking for a technically curious, customer-focused Solutions Architect who is ready to take the next step in their career. Whether you're an experienced Solutions Architect looking to broaden your impact or an emerging Principal Architect wanting greater ownership, this is an opportunity to shape complex customer solutions whilst growing your architecture career.
You'll work alongside sales, product, engineering and delivery teams to solve real business challenges for organisations across sectors including healthcare, local government, education and commercial enterprises. Every customer is different, meaning you'll combine strategic thinking with hands-on solution design to create practical, scalable outcomes.
This isn't about selling software in isolation. It's about understanding how organisations operate, navigating legacy technology, integrating multiple platforms and designing solutions that genuinely improve the way people work. You'll also play a key role in bringing these solutions to life through the creation of clear infrastructure diagrams, technical documentation and customer-facing materials that help stakeholders understand the value and impact of the proposed architecture.
If you enjoy solving complex technical problems, influencing customers, and being trusted as the technical expert throughout the sales journey, we'd love to hear from you.
What You Will Do
As a Principal Solutions Architect, you'll become a trusted technical advisor to both customers and internal stakeholders, helping shape solution strategy from discovery through to successful handover.
You'll:
- Design end-to-end solution architectures that address customer business challenges.
- Lead technical discovery workshops to understand customer environments, priorities and long-term goals.
- Translate business requirements into practical, scalable solution designs.
- Create high-quality infrastructure diagrams, technical documentation and solution artefacts to communicate architecture designs clearly to customers and internal teams.
- Work closely with Sales, Product Management, Engineering and Professional Services to create winning customer outcomes.
- Advise customers on cloud architecture, integrations, APIs, data flows and solution best practice.
- Navigate complex existing technology landscapes, identifying opportunities to modernise and simplify.
- Support technical responses for bids, tenders and customer presentations.
- Stay current with emerging technologies and industry trends, bringing fresh ideas that strengthen our customer propositions.
- Mentor colleagues and contribute to architectural best practice across the wider Solutions function.
What You Will Have
We're less interested in titles and more interested in your ability to solve complex technical problems.
You'll likely bring:
- Experience working as a Solutions Architect, Technical Architect or similar customer-facing architecture role.
- A passion for designing scalable SaaS and cloud-based solutions.
- Strong understanding of enterprise application architecture and system integration.
- Experience working with REST APIs, JSON and modern integration patterns.
- Confidence communicating technical concepts to both technical and non-technical audiences.
- The ability to lead customer workshops and build credibility with senior stakeholders.
- A collaborative approach and enjoyment of working across multiple teams.
It would be great if you also have experience with:
- AWS or other public cloud platforms.
- Integration platforms and middleware technologies.
- Financial, ERP, procurement or business management software.
- Highly regulated sectors such as Healthcare, Public Sector or Education.
Most importantly, you'll be someone who enjoys learning, asks great questions, embraces new technology and wants to continue developing as an architect.
Please note, applicants must have the legal right to work in the UK at the time of application.
