You’ll take ownership of the architectural vision, ensuring scalability, maintainability, and long-term technical health. While you work closely with de-velopment teams, you operate outside the Scrum teams — setting the guardrails, not run-ning the sprints.
You’ll be the one connecting long-term technical vision with day-to-day implementation. The teams will look to you for clarity, consistency, and confidence in the system’s evolution. You won’t manage people — but your impact will be felt across everything they build.

• Define the overarching system architecture and guide its evolution over time.
• Make key decisions on technology stack, system design, and integration patterns.
• Collaborate with Scrum teams to translate architectural principles into actionable solutions.
• Provide technical leadership, mentoring, and sparring to senior developers.
• Challenge existing solutions and drive continuous improvement in code quality and engineering practices.
• Ensure that architectural choices align with business goals and product strategy.
• Stay hands-on with coding and prototyping — you lead by example, not Power-Point.
