About the Company:

My client is a UK sovereign AI company developing secure, mission-critical artificial intelligence and data platforms for defence, national security, and strategic industry partners.

Our systems operate at the intersection of real-time data, autonomous decision support, and cloud-native infrastructure, with a strong emphasis on security, integrity, and performance.

We're scaling rapidly and seeking a hands-on Development & Operations Manager to lead the delivery and uptime of our AI cloud systems across AWS.

I need a JSON/AWS/Lambda Developer to bridge software engineering, DevOps, and cloud operations, ensuring secure, compliant, and high-availability environments for our AI workloads.

• Manage incident response, uptime SLAs, and operational dashboards.
• Collaborate with software engineers, AI researchers, and data scientists to optimise cloud performance.
• Maintain documentation and enforce secure coding and deployment standards.

Leadership & Delivery

• Experience in defence, aerospace, or regulated sectors preferred.
• Strong communicator with ability to translate technical ops into business risk and vice versa.
