• Raise and manage change tickets through relevant governance and approval processes

• Coordinate third-party engineering teams and internal build teams throughout the integration lifecycle

• Manage operational handover of integrations into the support model

• Experience managing change processes, security reviews, and connectivity work within financial services environments

• Excellent stakeholder management skills, with the ability to operate as the single point of contact for external providers

• Strong written communication skills for designs, architecture artefacts, and approval documentation
