• Create and support webhooks, event-driven pipelines, and synchronisation processes.
• Work directly with customer engineering teams on deployment, configuration, troubleshooting, and optimisation.
• Set up effective monitoring, logging, and error-handling for large-scale environments.
• Enhance internal tooling, automation, and observability to improve overall developer efficiency.
• Collaborate cross-functionally with engineering, product, and customer-facing teams across regions.

What They're Looking For

• Strong integration development experience (core requirement).
• Background in API or SDK development.
• Experience working with customers or in a technical consulting role.
• Good understanding of cybersecurity concepts and enterprise security tools.
• Someone who can lead integrations independently from design through to delivery.

• Highly Competitive base salary, flexible dependant on experience.
• Unlimited PTO
• Pension contribution
• Steer the direction of a soon to be multi-award-winning product worldwide
• Ownership and freedom to put your own stamp on the work you do
