Senior Solution Architect Architecture

Hybrid Working (minimum 6 days per month onsite)

Farringdon, London

Role purpose:

TCEU is investing in the evolution of connected vehicle data capabilities into secure, scalable and commercially valuable products and services for customers, partners and Toyota. As Senior Solution Architect, you will help define how these capabilities create value, how they should be productised, and how they can evolve from early concepts into reliable, governed and sustainable services.

This is a strategic role within the Architecture Practice, requiring a broad view across business capability, product strategy and technology architecture. You will own the architecture direction for a defined business domain while partnering closely with product, business and engineering leaders. The role requires enough technical depth to evaluate architectural trade-offs and guide solution direction, while keeping the primary focus on customer value, commercial outcomes and long‑term business capability.

• Shape the architecture and evolution of API‑enabled data products and commercial platforms, ensuring they support customer value, business outcomes, regulatory needs and long‑term scalability.
• Partner with product and business leaders to evaluate new commercial propositions, identify the capabilities required and define pragmatic paths from idea to operational service.
• Develop target‑state architectures, capability roadmaps and transition plans across business process, data, systems and operating model considerations.
• Help teams make difficult decisions where customer needs, commercial opportunity, regulation, cost, delivery complexity and technical constraints pull in different directions.
• Create and maintain business architecture models and views, including capability maps, value streams, customer journeys, operating models, commercial flows and information flows, using them to evaluate business scenarios, assess options and guide strategic and operational decision‑making.
• Record the reasoning behind important architecture decisions so that trade‑offs are visible, reusable and easy for other teams to understand.
• Support architecture and business governance forums with balanced recommendations, clear options and practical risk assessments.
• Work closely with product owners, engineers, business stakeholders, Toyota entities and external partners to move ideas from concept through design, delivery and operation.
• Maintain strong domain knowledge in data products, API monetisation, product catalogue, order management, subscription management, order orchestration, marketplaces or similar commercial platform domains.

• Proven experience as a Senior Solution Architect, Enterprise Architect, Business Architect or Domain Architect working on complex digital platforms, data products or commercial services.
• Strong business acumen, with the ability to connect architecture decisions to customer value, commercial outcomes, regulatory obligations and long‑term business capability development.
• Experience in at least one relevant commercial platform domain, such as API monetisation, data products, product catalogue, order management, subscription management, order orchestration, marketplaces, finance, telecoms or eCommerce.
• Experience defining strategy, operating models, capability roadmaps or commercial architecture for a product, platform or business domain, not only producing implementation‑level solution designs.
• Experience using business architecture techniques such as capability modelling, value streams, customer journeys or operating‑model analysis to connect strategy with technology change.
• Enough technical depth to work…
