• Strong Software Development / R&D Experience: Hands-on experience developing innovative solutions in a modern language (e.g. Java, C ), preferably in both program and R&D settings.
  
  

At Leidos, the Principal Solution Architect is more than a technical role—it is a strategic partnership. You will sit at the intersection of mission strategy and technical execution, influencing how our government partners approach their most complex GEOINT challenges. We offer the stability of an industry leader combined with the autonomy to shape technical tradecraft. If you are seeking a role where your architectural vision directly translates into mission success and business growth, we invite you to lead the way with us.
