Architect

Skills

About the Role

You will own the system architecture for the Payments and OTC portfolio and create a clear, current map of systems, contracts, and domain models that teams use. You will author high-level designs for new capabilities, review and sign off technical designs from teams, and record key decisions with their rationale. You will partner closely with product, engineering, and commercial leaders to shape scope, sequence work, and act as a solution architect for bank, payment provider, and partner integrations. You will drive payment orchestration and settlement architecture, shape repeatable integration patterns, and guide the client-side architecture as payment experiences move to a Flutter-based mobile stack. You will build compliance, security, and data protection into designs from the start, use AI tooling to accelerate your own design work, and connect the portfolio to the wider architecture community.

Requirements

• Recent experience architecting consumer-facing, high-scale distributed systems, with leverage coming from design, writing, and influence

• Experience using AI tools with sound judgment and excitement about helping an organisation adopt them
• Ability to translate architecture for product, compliance, commercial, and executive audiences
• BSc in Computer Science or another technical discipline, or equivalent working experience
