Technical Architect in Newcastle upon Tyne

We’re hiring a Technical Architect to lead the design and delivery of scalable, secure embedded services across Sage’s platform. You’ll sit at the intersection of engineering, architecture, and strategy; working with product, platform, and partner teams to define solutions that are technically robust, cloud‑native, and aligned with our long‑term vision. You’ll be instrumental in helping Sage embed services into diverse ecosystems by championing API‑first thinking, cloud architecture best practices, and scalable service design. This is a hands‑on role ideal for someone who enjoys both deep system‑level work and strategic architectural leadership.

This is a hybrid role requiring 3 days per week in our Newcastle office.

• 30 days – Onboard with the team, familiarize yourself with our Embedded Services Platform, and review current architectures and design patterns.
• 60 days – Lead architectural design sessions and align technical direction with product goals. Begin contributing to design of new core components.
• 90 days – Take full ownership of architectural decisions in one or more service areas. Collaborate across teams to improve scalability, maintainability, and integration patterns.

You’ll report to a senior technology leader and work closely with solution designers, product managers, cloud infrastructure specialists, and full‑stack engineering teams (primarily working in C# and React). You’ll also engage with Sage Partners to ensure seamless third‑party integrations.

• Exposure to embedded services at enterprise level, used by external partners and internal teams
• Broader impact through mentorship, code review, and technical leadership
• Strategic engagement with senior stakeholders, balancing delivery and long‑term vision

You’ll design core components of the Embedded Services Platform, guide architecture decisions, write and review code (primarily in C#), and ensure implementation quality across development teams. You’ll lead discussions with product teams, participate in partner enablement, and champion architecture governance while keeping a hands‑on role.

• 5+ years of experience in a Technical Architecture role, designing large‑scale cloud‑native enterprise systems
• Proven ability to turn complex business needs into scalable technical solutions
• Hands-on experience with C#, Java or a similar backend language
• Strong background in designing REST APIs and data schemas at scale

• Excellent communication and stakeholder management skills, including influencing across tech and non‑tech teams
• Experience providing mentorship and architectural guidance in agile product delivery settings
