Founding OR Engineer: Production Optimization

Haladir; San Francisco (CA); On-site; USD 180,000 - 240,000; Full time

Job summary

Haladir in San Francisco is seeking a quantitative engineer to design the optimization core of its products, including models for wave release, inventory allocation, routing in trucking networks, and labor planning for 3PL operations.

You will translate messy constraints into production-ready formulations, work closely with operators to understand decisions, and build scalable models that perform under real-world deadlines. This role offers autonomy and close collaboration with the founding team.

Qualifications

• Strong background in Operations Research, including MILP, constraint programming, heuristics, and local search.
• Research experience in Operations Research through publications, graduate work, or equivalent applied work.
• Able to implement production-grade models in Python using solver APIs such as Gurobi, CP-SAT, or HiGHS.
• Turn real-world constraints into mathematical models that can run in production.
• Strong judgment on solution quality, computational performance, and real-world operational constraints.
• Willingness to relocate to San Francisco and travel to potential customer sites.
• US work authorization.

Responsibilities

• Design optimization core for Haladir’s products, including models for wave release, inventory allocation, routing in trucking networks, and labor planning in 3PL.
• Turn messy operational constraints into production-ready formulations and systems.
• Work closely with operators to understand decisions and optimize what matters.
• Operate with greater autonomy and close collaboration with the founding team.
