Why this job matters

At BT, our Solution Architects design secure, scalable infrastructure that underpins critical national services.

  • Producing clear, actionable documentation including proposals, scopes of work, and risk assessments
  • Collaborating with stakeholders to align solutions with strategic goals and product roadmaps
  • Driving innovation in architecture to solve complex challenges in secure environments

  • Shaping product and architecture roadmaps aligned with business strategy
  • Designing and integrating APIs and web services across complex platforms

  • Applying cybersecurity principles to infrastructure and application design
  • Collaborating directly with customers and stakeholders to shape and deliver technical solutions
  • Integrating systems using APIs, web services, and cloud-native technologies
