Job Responsibilities

• Advance applied research across the LLM stack, including model training, adaptation, inference, and agentic systems.
• Design, build, and release foundation-model and agentic systems that support high-value business workflows from prototype to production.
• Develop methods to evaluate, verify, and monitor models and agents, including faithfulness, hallucination detection, and workflow verification.
• Enhance research capabilities in model explainability, reliability, and interpretability.
• Provide innovative research solutions to internal project teams.
• Collaborate with researchers to document findings in scientific papers and present at conferences.
• Contribute to intellectual property by pursuing necessary protections for generated IP.
• Work with cross-functional teams to integrate AI solutions into business processes.
• Present research outcomes to stakeholders and at industry conferences.
• Stay current with advancements in AI and machine learning.
• Foster a culture of innovation and continuous improvement within the team.

Required Qualifications, Capabilities, and Skills

• Ph.

D. in computer science, machine learning, or related fields, plus at least 2 years of experience (industry or postdoc), or a Master’s degree with equivalent applied research and engineering experience plus 4 years of industry experience.

• Ability to build and ship AI/ML systems, ideally involving LLMs.
• Proficiency in Python and modern ML frameworks such as Py Torch or JAX.
• Hands-on experience across the LLM lifecycle, including fine-tuning, prompting, serving, and evaluation.
• Experience in scientific technical writing.
• Strong communication skills and ability to present findings to a non-technical audience.
• Experience in model training and adaptation (e. g., supervised fine-tuning, RLHF, preference optimization, distillation, parameter-efficient methods).
• Experience in inference and serving (e. g., test-time compute, speculative decoding, quantization, KV-cache management).
• Experience in agentic systems (e. g., planning, tool and function calling, retrieval-augmented generation, orchestration).
• Experience in evaluation and faithfulness (e. g., benchmarks, LLM-as-judge, hallucination and groundedness detection, workflow verification).
• Experience in explainability and reliability (e. g., attribution and interpretability, uncertainty and calibration, monitoring for drift and failure).

Preferred Qualifications, Capabilities, and Skills

• Strong record of impact through shipped AI systems or publications at top venues (such as Neur IPS, ICML, ICLR, ACL, EMNLP).
• Experience with foundation models, including tabular foundation models.
• No prior familiarity with finance or financial use cases required.
