We are looking for a remote, full-time AI Software Engineer to join our US client's team. You should have a minimum of 3+ years of experience developing and delivering commercial software, with a solid background in AI/ML, Python, TypeScript/JavaScript, and C#/ .NET. In this role, you will leverage deep expertise in NLP and ML to help build scalable, production-grade language technology systems. This position is ideal for someone passionate about transformer models, audio processing, large-scale data pipelines, and real-world ML deployments. You will have a high impact on shaping the future of language accessibility and global communication through sophisticated, scalable ML systems. If you're excited to build at the intersection of language, audio, and AI, and to do so in a real-world product used globally, we'd love to meet you. Our U.S. client is a fast-growing, mission-driven language technology company developing the next generation of interpretation and multilingual communication platforms. Their goal is to break down language barriers worldwide by leveraging cutting-edge speech and language AI to power solutions such as video remote interpretation (VRI), over-the-phone interpretation (OPI), interpreter scheduling, simultaneous interpretation, and more.
