Principal Software Engineer

Annapolis Junction, MD
Full Time
Experienced

Principal Feature Architect, Mission Software

Make an Impact Where It Matters Most

At Intelliforce, we build software that supports mission environments where clarity, scale, and reliability matter every day. In this role, you will serve as the technical anchor for a new feature or capability being added to an existing product. You will help shape the architecture, translate complex business needs into clean technical designs, and guide delivery from concept through deployment. This is a strong fit for an engineer who likes solving hard problems, influencing system direction, and building software that has to perform in real operational environments.

What Makes This Opportunity Stand Out

This role gives you the chance to own more than code. You will lead the technical vision for a new capability, define what done looks like, and work closely with an Integrated Feature Team to carry the work across the full lifecycle. The job blends architecture, design, coordination, mentorship, and quality leadership, so your impact shows up in the design, the execution, and the strength of the team around you.

At Intelliforce, your work is visible and your voice carries. Because we support prime programs, our teams stay close to meaningful mission work with real momentum. Because we are a small business, leadership is accessible, communication is direct, and strong engineering gets noticed. Add in long-term stability, strong benefits, and a people-first culture, and this becomes more than another senior engineering role. It is a chance to help shape a capability from the ground up and drive it to a high-quality finish.

Here’s What Your Day-to-Day Could Include

  • Lead the architecture and design of a new feature or capability from early concept through delivery
  • Break down complex business requirements and determine system impact across the product
  • Create robust technical designs using object-oriented principles and patterns that integrate cleanly into the existing platform
  • Act as the feature lead, owning definition of done and guiding work through development, testing, deployment, and sustainment
  • Serve as the technical liaison to Systems Engineering and other partner teams to align on constraints, dependencies, and approach
  • Decompose high-level designs into actionable work for the development team
  • Manage feature status, risks, and progress updates for leadership and stakeholders
  • Conduct rigorous merge request reviews to uphold code quality, security, and performance standards
  • Mentor junior and mid-level engineers and help strengthen engineering best practices across the team

Minimum Qualifications

  • Citizenship: Must be a U.S. Citizen. We cannot sponsor visas

  • An additional 4 years of Software Engineering experience may be substituted for the degree for a total of 16 years
  • 5 years of work experience in the SIGINT, IA, or IT domains

Required Skills

  • Expert-level Java experience, Java 17 or newer preferred
  • Deep understanding of SOLID principles and object-oriented design patterns
  • Strong experience with the Spring Boot ecosystem
  • Proficiency in REST interface standards and best practices
  • Ability to architect and design new features from complex business requirements
  • Ability to communicate and facilitate cross-team collaboration
  • Excellent oral and written communication skills, including the ability to clearly explain architecture and design concepts
  • Ability to write technical documentation including wiki pages, blogs, and XML or HTML content
  • Willingness to mentor junior and mid-level software development peers
  • Strong leadership, organization, and feature ownership skills across the software lifecycle

Your decision to complete the form and your answer will not harm you in any way.
