As a AI Engineer, you will play a key role in building AI systems end-to-end. This is a fast-paced, hands-on role for engineers with high-agency and founder mindset. We’re looking for stellar engineers who take full ownership, thrive in uncertainty, and are willing to go the extra mile to achieve ambitious goals in a fast-paced startup environment.
If you are a passionate builder who thrives at the intersection of AI, ML, data engineering, and full-stack development - this is your opportunity to shape how users interact with AI.
What you will be working on
- Work across the full stack to build, deploy and optimize AI agents end-to-end
- Work with embeddings and fine-tune LLMs for classification and reranking
- Optimize algorithms for product search
- Apply RLHF & DPO to align LLMs with human feedback
- Build data pipelines to process large-scale unstructured data efficiently
- Make our backend scalable, stable and efficient
What we're looking for
