- Collaborate directly with consultants and clients to translate business requirements into technical solutions that drive measurable value for global law firms.
The ideal candidate
- Proven experience in mathematical modeling, optimization, or operations research combined with strong production software engineering skills.
- Skilled in data engineering and comfortable working with messy, real-world datasets to build reliable, production-ready simulation models.
- Excellent communicator capable of structuring ambiguity and collaborating with non-technical stakeholders to deliver high-value technical outcomes.
