We are scientists, engineers, economists, activists and everyday people who develop and advocate for innovative, practical solutions to some of our planet’s most pressing problems—from combating global warming and developing sustainable ways to feed, power, and transport ourselves, to fighting misinformation, advancing racial equity, and reducing the threat of nuclear war.

This is a permanent position open to candidates who will have completed their Ph.D. or other advanced degree in a relevant field, or those with equivalent experience.

  • In coordination with the GSP research director and other GSP staff, create a research plan that supports advancing GSP’s short- and long-term policy goals and UCS’ commitment to racial justice. Review and support other analysts’ work and solicit review and input from other team members.
  • Represent UCS as spokesperson with the media, the scientific and arms control community, government officials, coalition partners, and other stakeholders.
  • Contribute to a collegial and respectful work culture and participate in program and organization processes to advance an equitable and just workplace and to help UCS to become an anti-racist organization.
  • Maintains awareness of role as representative of UCS; ensures activities and statements enhance organizations reputation and credentials among press, public, and private sectors; promotes UCS, advances organizational objectives, and enhances funding opportunities.
