AI Research Scientist · Internship

What you'll do.

  • Conduct research on how large language models can support optimization and operations research tasks.
  • Explore LLM-based methods for mathematical modeling, problem formulation, algorithm design, solver selection, and decision-support workflows.
  • Develop and test workflows involving coding with LLMs in the loop.
  • Study how LLMs can generate, debug, verify, and improve optimization models and solver code.
  • Design evaluation methods and benchmarks for LLM-generated optimization formulations, code, and solutions.
  • Implement research prototypes and computational experiments.
  • Analyze failure cases and improve model reliability, correctness, and usefulness.

What we look for.

  • Candidates pursuing a PhD, Master's degree, or Bachelor's degree in relevant fields are welcomed.
  • Demonstrated research ability, strong technical depth, and experience in optimization, LLMs, AI agents, algorithms, or machine learning are highly valued.
  • Ability to work independently in a fast-paced startup environment with evolving priorities.
  • Excellent communication skills for discussing technical concepts with cross-functional teammates.

Technical expertise.

Optimization & Modeling

  • Experience with LP, MIP, NLP, or constraint programming.
  • Ability to translate business problems into mathematical models (variables, objectives, constraints).
  • Familiarity with solvers like Gurobi, CPLEX, SCIP, or OR-Tools.
  • Understanding of solver behavior, computational bottlenecks, and model debugging.
  • Experience with practical problems such as routing, scheduling, or resource allocation.

Engineering & AI

  • Expertise in code structure, testing, logging, and building reproducible experiment pipelines.
  • Ability to integrate AI components with external tools, APIs, and enterprise systems.
  • Strong judgment on system performance, scalability, and failure handling.
  • Knowledge of LLM workflows (prompting, retrieval, agents), machine learning evaluation, and structured code generation.
