Job description

Make an Impact Where It Matters Most

At Intelliforce, we build and sustain mission software that has to operate as part of a much larger ecosystem. In this role, you will support Application Integration efforts by helping ensure applications, services, and data flows continue working together as platforms evolve.

What Makes This Opportunity Stand Out

This role puts you at the point where software development meets real-world mission integration. You will not be working on an isolated application. You will help determine how capabilities interact with other systems, how data moves through the environment, and what needs to change as mission platforms modernize.

A major part of the work involves sustaining what already matters while improving it for what comes next. You will refactor software for stronger interoperability, support system integration and testing, maintain policy compliance, and help deliver capabilities to external partners.

At Intelliforce, your work is visible and your technical judgment matters. Because we support prime programs, our engineers stay close to meaningful mission work and the teams relying on what they build. 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 is an opportunity to have real influence across the full lifecycle of a mission capability.

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

• Provide software engineering, systems engineering, Information Assurance, and testing support for mission efforts
• Sustain existing mission software and integrated capabilities
• Maintain interoperability with upstream and downstream systems
• Analyze and troubleshoot system data flows across interconnected environments
• Develop and refactor software to improve interoperability within the platform
• Support build, integration, testing, and deployment activities
• Support external mission partners integrating with or operating supported capabilities
• Maintain standards and policy compliance across supported systems
• Investigate software and integration issues and implement technical solutions
• Modify existing software to improve performance, compatibility, or functionality
• Participate in software testing, integration testing, and operational validation
• Develop and maintain technical and system documentation
• Work with systems engineers, software engineers, security teams, testers, and mission stakeholders to resolve technical issues
• Evaluate system behavior, data movement, interfaces, and operational dependencies as capabilities evolve

Minimum Qualifications

• Clearance: Top Secret Clearance with Full Scope Polygraph, must be active. We do not have the ability to sponsor clearances
• Citizenship: Must be a U.S. Citizen. We cannot sponsor visas
• 20 years of Software Engineering experience on programs and contracts of similar scope, type, and complexity
• Bachelor’s degree in Computer Science or a related discipline from an accredited college or university
• Four additional years of Software Engineering experience on projects with similar software processes may be substituted for the bachelor’s degree
• Five years of demonstrated cloud experience supporting distributed scalable data technologies and related processing environments

Required Skills

• Experience developing, maintaining, and enhancing complex software systems
• Experience integrating software into new or modified systems and operating environments
• Experience troubleshooting software, integration, and interoperability issues
• Experience maintaining interfaces and data flows between upstream and downstream systems
• Experience refactoring software to improve interoperability, maintainability, or performance
• Experience supporting software build, integration, testing, and deployment activities
• Experience working in environments with defined security, IA, and policy requirements
• Experience analyzing user and system requirements to derive software design and performance requirements
• Ability to debug existing software and correct defects
• Experience developing or implementing algorithms that meet functional and performance requirements
• Experience developing and executing software test procedures
• Ability to write and review software and system documentation
• Experience analyzing systems flow, data usage, work processes, and problem areas
• Experience working with complex data repositories and interfaces
• Strong collaboration skills across software, systems, security, testing, and operational teams

Desired Skills

• Experience supporting Analytical Application Integration or similar enterprise integration environments
• Experience with software modernization or application refactoring effortsExperience integrating software into converged or shared mission platforms
• Experience supporting deployed or expeditionary mission systems
• Experience working directly with external mission partners
• Experience sustaining operational software throughout its lifecycle

• Experience serving as a technical lead on software development or integration efforts
• Experience recommending new technologies and processes for complex software projects
• Experience overseeing software quality and technical implementation across development teams
