Our platform is already protecting sensitive sites for private and government agencies, and we’re just getting started.

The Impact You’ll Make As a Senior Backend Engineer at Conntour, you’ll be one of the first engineers shaping the foundation of our platform. You’ll design and build high-scale, performance-critical backend systems that power real-time video and AI-driven workflows in high-stakes environments. Your work will directly influence our architecture, infrastructure, deployment strategy, and engineering standards from the ground up. This is a hands-on role for someone who loves building robust systems, optimizing performance, owning infrastructure, and solving hard problems where reliability and speed matter.

What We’re Looking For

• 4 + years backend or systems engineering in production environments.
• Deep knowledge of distributed systems, networking, and databases.
• Production proficiency with Docker, Kubernetes, CI/CD, and observability stacks.
• Comfort with pub/sub architectures (Kafka, MQTT).
• Experience designing and operating AI inference services at scale (Triton, TensorRT, ONNX Runtime) across distributed GPU clusters.
• Experience with computer-vision/AI model serving, on-prem/edge deployments, or security-sensitive/government environments.
