Original job description

Principal Mission Engineer (Full Stack) (Secret Clearance Required)

The Team:

Information processing and sense-making systems are the lifeblood of national security efforts, facilitating an understanding of the global situation, strategic planning, and tactical execution. The reliability, accessibility, and sophistication of these systems can determine the outcomes of conflicts before they begin. STR’s Analytics and Command & Control (AC2) Division focuses on developing actionable, advanced technology solutions to provide asymmetric advantages within the information domain.

The Mission Applications (MA) Group within the AC2 Division specializes in ensuring the technology that STR creates produces outsized mission impact. Staff within the MA group have a deep understanding of missions and technology needs for national security with skills targeting transition of technology to operational use, including product management, UX Product implementation, software integration & mission engineering, platform engineering, DevOps, and program management. MA staff combine with other science and engineering staff from the various STR research and development groups to form dedicated product teams focused on accelerating the operational transition of cutting-edge software technologies.

The Role:

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.

Who You Are:

Must be a U.S. citizen
Active US Security Clearance
BS in Computer Science or related technical field with at least 8 years of work experience
Experience deploying software for DoD or IC missions
High sense of ownership and a track record of delivering high impact work
A passion for crafting user-centric interfaces and a keen eye for design details
Demonstrated strong knowledge of modern technologies such as React, TypeScript, and Python
Knowledge of performance-focused tools and techniques for rendering large datasets and building responsive, smooth interfaces
A demonstrated ability to adopt new languages, libraries, and technologies
Organized, detail-oriented, and with an ability to work both independently and collaboratively
Demonstrated experience as an effective communicator to both technical and non-technical audiences

Even Better:

Active Security Clearance at the Top Secret level with SCI Eligibility
Advanced Degree in Computer Science, Information Technology, or related technical field
Prior US Military Service with experience in joint planning, large force battle monitoring, and fluidity with large force debrief best practices
