Join us in the endeavor of accelerating the path to safe & useful clinical super intelligence by becoming part of our community of problem solvers, technologists, clinicians, and innovators.
The Role:
As a Staff Research Engineer at Ambience, you will push the boundaries of generative AI by translating cutting-edge research into working prototypes and experimental platforms. You27ll work closely with fellow researchers, engineers, and product leads to explore novel architectures, fine-tuning methods, evaluation paradigms, and data strategies26mdash;helping to define what27s possible with frontier AI models.
Our engineering roles are hybrid 26mdash; working onsite at our San Francisco office three days per week.
What You27ll Do:
- Prototype and Advance LLM Systems: Build and benchmark LLM-based systems and agents using open-source and proprietary models. Rapidly prototype new capabilities through fine-tuning, adapters, and reinforcement learning approaches.
- Drive Research-First Experimentation: Translate recent academic papers into reproducible experiments, focusing on fine-tuning (e.g., LoRA, QLoRA, DPO), model alignment, and hallucination mitigation techniques. Design clear experiment plans and share findings across the team.
- Build and Evolve Evaluation Pipelines: Define evaluation methodologies using human-in-the-loop feedback, synthetic benchmarks, and task-specific metrics. Implement continuous evaluation pipelines to track regressions and breakthroughs.
- Shape Data and Training Strategy: Curate datasets via synthetic generation, targeted scraping, and annotation pipelines. Establish practices for discovering failure cases and improving model robustness over time.
- Contribute to a Research-Driven Culture: Write research papers, internal memos, and blog posts. Foster a culture of experimentation, documentation, and knowledge-sharing across research and engineering teams.
