- Develop robust backend systems to power real-time search, discovery, and powerful generative AI features.
- Blend innovation with practicality, applying the latest AI research to build impactful, production-ready solutions.
- Collaborate with engineers, product managers, and multi-functional teams to deliver bold technical projects.
You Have:
- 6+ years of strong programming skills in at least two languages (Python, C#, C++, Java) and a willingness to learn others as needed.
- 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.
