VIEW JOBS 10/21/2020 10:34:17 AM 2021-01-19T10:34 In a space where it is hard to be unique, our client is a VERY DIFFERENT COMPANY.  The founders, former Intelligence Community technology executives, have built the kind of company they always wanted to be part of.  The most unusual aspect is that people move freely from project to project - in addition to their 20+ vehicles for DIA and CIA work and their commercial customers, the CEO often can literally pick up the phone, call the customer, and get added to new work that interests an employee.  They help their people change projects all the time: you don't get stuck in one role for years (unless you want to stay in it). And wouldn't it be nice to be somewhere where you don't have to worry about a layoff if a project ends?  The work itself is also amazing and as close to the mission as you will find - Data Science and Analytics work, counterterrorism, counterproliferation, targeting, virtual operations, exploits, HUMINT research and other missions.  <br /> <br /> They prime on several programs and also have a number of subcontracts, and they always need TS/SCI + FS Poly Data Scientists, Data Engineers, Data Analysts, Analytic / Big Data Software Engineers, Full Stack Developers, Cloud Engineers, and Systems Administrators in Reston, Chantilly, McLean, and other sites in Virginia. Salaries here are quite good, plus a 10% 401(k) contribution, 7 weeks of PTO, and excellent health/medical/dental coverage.  It's a unique combination of great work, great people, and great compensation - low bureaucracy, technology agnostic, massively mission-focused, and extremely well-funded.  And during your interview process, the CEO can meet you high-side to talk about the specifics of what they do.
