The Role
We’re looking for an ML Engineer who’s passionate about applied research and eager to work on the frontier of AI agent development. You’ll bridge research and production — exploring, prototyping, and deploying models that push the limits of what autonomous agents can do in real-world settings.
Key Responsibilities
- Conduct applied research to evaluate, fine-tune, and adapt large language models and other AI architectures for our use cases
- Prototype experimental models and pipelines, testing novel approaches to agent orchestration, prompt design, or retrieval-augmented generation (RAG)
- Design and run experiments, analyze results, and iterate rapidly to improve agent performance
- Build robust, reproducible pipelines for data collection, preprocessing, and training
- Collaborate with backend and product engineers to operationalize research prototypes into production services
Requirements
- 2–4 years of experience in applied ML research or an industry role with a strong R&D component
- Solid foundation in machine learning fundamentals and experience working with LLMs or NLP models
- Proficiency in Python and ML frameworks such as PyTorch or TensorFlow
- Hands-on experience designing experiments, evaluating models, and analyzing data
- Familiarity with literature reviews and an eagerness to stay up-to-date with emerging techniques
Nice to Haves
- Experience with vector databases, embeddings, or semantic search
- Familiarity with reinforcement learning from human feedback (RLHF)
- Familiarity with agent frameworks
- Contributions to open-source ML projects or published research papers
Why You Should Join
- Competitive equity & pay - get in early and own what you build.
- Work closely with experienced founders with a proven startup track record.
- Move fast, ship fast - no corporate bureaucracy.
- Shape the AI revolution in healthcare - massive market, untapped potential
