Career portals for companies on the 2026 Fortune 500 list.
OR-related employer
Employers selected for work involving optimization, simulation or operational decision systems. Relevant duties determine which jobs qualify. For example, a finance role at a solver company would not qualify simply because the company makes optimization software.
Technology employer
Selected technology companies with potential decision-system work, such as routing, scheduling, resource allocation or marketplace operations.
Y Combinator company
Selected companies listed in Y Combinator's company directory, with a recorded directory link.
Government or public research
Government agencies, public-sector employers and research laboratories with potential applied decision work. Academic positions remain outside scope.
Corporate group coverage
Separate subsidiary or business-unit career portals that extend coverage beyond a parent company's board, such as Kroger and 84.51°. Distinct boards are kept; duplicate links to the same board are removed.
