Define and guide system architecture, balancing trade-offs between speed, scalability, maintainability, and security. Work actively with the architecture community to define processes, drive technology adoption, and share best practices. Ensure non-functional requirements, performance, reliability, scalability, and security are addressed in all solution designs. Champion accountability from design through production by ensuring systems are observable and meet agreed Service Level Objectives (SLOs). Lead Root Cause Analysis when issues occur. Lead estimation and feasibility assessments, making sure plans are realistic and aligned with team skills and capacity. Contribute to structured release planning and communication, ensuring phased rollouts deliver value early (MVP-first). Support post-release reviews and retrospectives. Uphold coding standards and promote automated testing while embedding a quality-first culture in the development process. Identify and prioritise maintenance and technical debt, making its impact visible by translating it into customer and business outcomes. Mentor and coach engineers through feedback, knowledge sharing, and motivation. Foster alignment and help the team galvanise around technical solutions and goals. Work closely with Product Managers, Engineering Managers, QA, Designers, and other Engineers and Tech Leads to align technical direction with product strategy. Communicate technical concepts clearly to both technical and non-technical stakeholders.
