## Description

As a Principal Mission Engineer (Full Stack) in the Mission Applications Group, you will develop and deploy software essential for a specific, real-world objective or "mission" in partnership with our customers. We are looking for engineers who are high ownership and have a track record of delivering high impact work.

You have: 1) expertise in developing and deploying software solutions in complex and high-security environments, 2) deep domain knowledge in the complex missions executed across the Department of Defense, and 3) expertise in modern frameworks, building full stack applications, and integrating APIs for deployment in high-security environments.

You will work as a leader of software teams to design, develop, and maintain software systems deployed in operational use. You have experience managing customer relationships while simultaneously leading engineering teams to ensure the delivered product meets the highest standards of quality, reliability, and performance. This role includes:

 * Build Prototype Capabilities: Break down use cases and user-defined problems, build an MVP, and rapidly evolve a solution into a cohesive application.

 * Rapidly Scale Applications: Continue accelerated development trajectory on existing applications by building new workflows, increasing scalability and making high impact improvements, and addressing additional customer pain points in the context of existing applications and workflows.

 * Develop and Enhance Features: Create high-performance, visually appealing frontend solutions that handle complex use cases effectively. Ensure the product is fast, smooth, and intuitive to use, even under heavy load.

 * System Integration: Leading cross functional engineering teams to design, build, and deploy a cohesive system. Integrate independent capabilities into existing solutions.

 * Customer Collaboration: Working closely with end-users and customers, who are typically military or Government operators, to understand their requirements and translate them into software features. You are experienced in product discovery best practices.

 * Deployment and Field Testing: Traveling to integration sites to deploy, test, and triage software in secure operational environments. On average, travel to customer sites should not exceed one week per month.

This role will take advantage of STR's flexible, hybrid environment - when the work does not require use of STR's or the customer's facilities, you are welcome to work remotely.
