About this directory

We read the careers sites of the energy and commodities employers we track and list early-careers openings seen there in the last 8 days. An opening can close before we next check its site, so always confirm on the employer's page. We do not take applications or see who applies. Programme types and functions come from each posting's title. An entry-level job is one whose posting asks for two years of experience or less (and no more than three at the top of a range), or, where it states no years, whose title says junior or entry-level or which the job board it was listed on files as entry-level; senior, lead, manager and level II+ titles are left out. Postings that state nothing are not listed. For counts by country, function and pay disclosure, see the early-careers overview.

U.S. federal openings come from the USAJOBS API of the U.S. Office of Personnel Management (OPM). They were retrieved from USAJOBS in the last 8 days, and this directory was updated 30 October 2026. Each links to the official announcement on USAJOBS, where you apply by its instructions. Plutarch is not operated, sponsored, approved or endorsed by OPM or any federal agency.
