Senior Software Developer
About The Position
We're looking for an experienced Senior Software Developer to join our growing team. The ideal candidate is a strong full-stack engineer who is comfortable working across modern front-end frameworks and .NET back-end technologies. This is a great opportunity to contribute to the architecture, design, and development of scalable, secure, and high-performing business solutions. At Leidos, we don't want someone who "fits the mold"-we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, "what's next?" before the dust settles on "what's now." If you're already scheming step 20 while everyone else is still debating step 2… good. You'll fit right in.
