Senior software engineers must have strong communication skills, for socializing plans and potential options and working toward well-specified product behaviors.

    • U.S. Citizenship (position entails access to Controlled Unclassed Information).
  • Typical qualifications:
    • Bachelor’s or master’s degree.
    • 8+ years relevant industry experience
    • Able to obtain DoD security clearance.


Required Skills:

  • Exploring code repositories to understand how existing features have been implemented.
  • Updating code to address defects, or to create new capabilities.
  • Designing and implementing new features.
  • Writing documentation for users or maintainers.
  • Writing automated tests.
  • Learning new technologies.
  • Researching technologies for potential adoption.
  • Communicating clearly and efficiently around all of the above.
  • Collaborating productively with stakeholders and other engineers.


Preferred Skills:

  • Git
  • Python
  • Bash
  • Linux
  • Data visualization (e.g. matplotlib, plotly)
  • Docker
  • AWS 
  • Javascript/Typescript/Angular 


Physical Requirements/Working Conditions:

  • (Strongly preferred) Ability to travel to Groton HQ on short notice.


Travel Requirements (If Applicable):

  • Occasional travel for at-sea support or major client milestones.
