Perception Engineer at AI-powered physical security & robotics startup

This is a role that TechTree is recruiting for on behalf of one of our clients. TechTree is an AI-driven recruitment platform working with high-growth companies.

When you apply, our AI Agent matches you not just to this role , but to other relevant opportunities across our network, so one application can unlock multiple roles. Perception Engineer — Own perception for a multi-sensor security & robotics stack (Zurich) A founding team building the intelligent software that powers physical security in the real world — enabling robots and sensors to handle dangerous and critical tasks — is hiring a Perception Engineer to build and own their perception systems. This is a builder's role: start from the best available models and turn them into reliable, real-time systems that detect, track, and re-identify objects across cameras, running efficiently on edge hardware.

What You'll Work On → Cross-camera object re-identification (ReID) for people and vehicles across distributed camera networks

→ High-throughput object detection and multi-object tracking across many simultaneous video streams

→ Vision-language models (VLMs) for open-vocabulary detection and scene understanding

→ Video ingestion and streaming (RTSP, WebRTC) from camera to model

→ Edge deployment: TensorRT, quantization, pruning for real-time targets on Jetson and edge-class devices

What We're Looking For → 3+ years shipping computer vision or ML systems in production

→ Strong grasp of SOTA techniques for cross-camera ReID, detection, and tracking

→ Hands-on VLM experience

→ Experience deploying models to edge hardware (TensorRT, quantization, latency tuning)

→ Strong Python and PyTorch (or JAX)

→ Based in or willing to relocate to Zurich, Switzerland (remote considered for exceptional candidates)
