Job description

About the Role

We are publishing on behalf of a client searching for a senior-level Chief Technology Officer (CTO) role focused on building, operating, and owning mission-critical transactional systems. The CTO is responsible not for writing code personally, but for ensuring that systems operate correctly, securely, and reliably at all times.

Key Responsibilities

• Design and launch transactional infrastructure (payments, bookings, statuses)

• Build and own state machine and event-driven architecture

• Implement idempotent operations to prevent double charges and inconsistent states

• Integrate payment providers (webhooks, retries, reconciliation)

• Ensure full auditability and traceability of all system operations

• Oversee system security, including access rights, roles, and secrets

• Organise and govern production support (SLAs, incidents, post-mortems)

• Provide architectural leadership and accountability for system outcomes

Skills

Experience

Transactions & Payments:

• Proven hands-on experience with payments, webhooks, idempotency, and reconciliation

• Clear understanding that a successful HTTP response does not necessarily equal a successful transaction

Architecture:

• Design and operation of state machines and event-driven systems

• Ability to clearly explain system states, recovery after failures, and handling of repeated or delayed events

Security & Control:

• Hands-on experience with role-based access control (RBAC), audit logs, and secrets management

• Experience working with legally or financially sensitive data

Production & Accountability:

• Experience running live production systems with defined SLAs

• Exposure to incidents and post-mortem processes

• Strong ownership mindset and responsibility for system
