• Exposure to front end technologies and frameworks such as React or Angular.
• Practical experience crafting and scaling backend systems in cloud environments.
• Confirmed expertise across the stack, including backend development to deploying ML models in production environments.
• Familiarity with image or 3D object understanding, ideally within gaming or content creation industries.
• A “get stuff done” mentality with a readiness to solve challenges and take on tasks beyond your comfort zone to get results.
• A great foundation in computer vision, AI, or related fields.

You Are

• Experience with large-scale search systems, generative AI, or semantic content understanding.
