• Design and implement robust, scalable APIs and backend services from the ground up.
• Develop core platform features such as authentication, authorisation, and role/permissions management, integrating tightly with our Agentic API layer that powers open-source AI workflows.
• Collaborate closely with the CTO and leadership team to shape the architecture and long-term technical strategy of our AI-native platform.
• Lead backend development initiatives, making key technical decisions and driving delivery of high-impact features.
• Take ownership of system performance, reliability, and maintainability — ensuring our backend can scale with the business.
• Stay close to emerging AI technologies and help assess how they can be incorporated into our stack.
• Contribute across the full stack where needed.
