  • Support HR, onboarding, finance, and office operations as needed.

  • Demonstrated experience or willingness to work with federal grant or contract administration (NSF, DOD, DOE, or similar agencies).
  • Strong organizational and time management skills; able to track multiple awards and deadlines simultaneously.
  • Strong written and verbal communication skills, including professional correspondence with government agencies and investors.
  • Proficiency with standard productivity tools (Google Workspace, Microsoft Office, or equivalent).
  • Ability to work on-site in Woburn, MA. Cambridge, MA office opening in August 2026.
Preferred qualifications
  • Direct experience with NSF SBIR/STTR or DOD/DOE SBIR programs.
  • Familiarity with SAM.gov, research.gov, grants.gov, or equivalent federal systems.
  • Familiarity with cost-reimbursable contract administration and invoicing.
  • Background in bookkeeping or financial tracking tools (Quick Books, Expensify, or similar).
  • Prior experience at a startup, university research office, or government contractor.
  • Genuine interest in deep technology, manufacturing, or science and engineering.
What we offer
  • Y Combinator and NSF-backed startup with real traction.
  • High-visibility role with direct access to and collaboration with the founding team.
  • Potential for equity incentive based on contributions and performance.
  • A low-bureaucracy, collaborative culture where your work has immediate and visible impact.

  • Flexible working arrangements and a culture that respects your time and autonomy.
