Your Tasks

As a Senior Computer Vision Engineer (f/m/d), you will play a leading role in the design and implementation of cutting-edge computer vision systems that power intelligent defense applications. Working in a dynamic cross-functional team of data scientists, ML engineers, and Site Reliability Engineers, you will drive the technical direction of AI-based perception solutions from concept to deployment.

• You design, develop, and optimize advanced deep learning models for computer vision, leveraging the cloud-native Sthenos platform.
• You lead experimentation with state-of-the-art vision architectures such as YOLO, Faster R-CNN, DETR, or transformer-based models, and evaluate their applicability to real-world defense scenarios.
• You mentor and guide junior engineers and data scientists, providing technical direction, code reviews, and best practices for model development and deployment.
• You take ownership of end-to-end model lifecycles — from data exploration and training to large-scale evaluation, integration, and performance monitoring in production environments.
• You collaborate with other ML engineers to define data collection, curation, and annotation strategies, ensuring datasets are optimized for training and validation.
• You explore reinforcement learning and simulation-based training methods to enhance visual perception and decision-making systems.
• You stay up to date with the latest advancements in computer vision, deep learning, and distributed AI, and actively contribute to shaping the AI strategy of the organization.
• You represent Sthenos in external conferences and meetups, sharing your team’s achievements and helping establish thought leadership in AI-driven defense systems.
