Job description

Software Engineer (SWE-3) – Mission Application Development

Make an Impact Where It Matters Most

At Intelliforce, we build software that directly supports national security missions where reliability, speed, and precision matter. In this role, you will help design, evolve, and sustain a critical software ecosystem used in real-world operations. You will work on systems that are actively deployed, relied on every day, and expected to perform in demanding environments. This is a strong fit for an engineer who wants meaningful work, modern tooling, and a direct connection between what they build and how the mission moves.

What Makes This Opportunity Stand Out

This is not a role focused on abstract problems or software that never leaves the lab. You will work on real mission applications, including sustainment and enhancement of existing capabilities like DINO, while also helping build new services and integrations that keep the platform moving forward. One day might focus on troubleshooting production issues in Linux. Another might center on building Python or Rust services, integrating with RabbitMQ, or deploying workloads into Kubernetes. The work stays varied, hands‑on, and closely tied to systems people depend on.

At Intelliforce, you join a tight‑knit engineering team where your work is visible and your contributions matter. 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 software role. It is a chance to build and sustain software with real operational value.

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

• Design and build new software capabilities for mission applications
• Sustain and improve existing mission applications, including DINO
• Troubleshoot production issues in Linux environments
• Develop new Python or Rust services
• Integrate services with message brokers such as RabbitMQ
• Deploy containerized workloads into Kubernetes
• Collaborate with system engineers, mission partners, and developers to turn requirements into working solutions
• Participate in code reviews, testing, container builds, and CI/CD pipeline updates
• Support software integrated and deployed across mission systems that demand stability and performance

Minimum Qualifications

• Clearance: Top Secret Clearance with Polygraph, must be active. We do not have the ability to sponsor clearances
• Citizenship: Must be a U.S. Citizen. We cannot sponsor visas
• Master’s degree in Computer Science or a related field with 5 or more years of relevant software engineering experience
• Bachelor’s degree in Computer Science or a related field with 7 or more years of relevant experience
• Or 9 or more years of software engineering experience in lieu of a degree
• Experience must support programs of similar scope, complexity, and mission impact

Required Skills

• Strong experience working in Linux environments, including daily use of the CLI
• Hands‑on Python 3 development experience in production systems
• Familiarity with or willingness to learn Rust
• Experience working with NoSQL databases, particularly MongoDB
• Experience building and deploying containerized applications using Docker or containerd
• Familiarity with message brokers such as RabbitMQ
• Experience with CI/CD pipelines, including GitLab CI
• Understanding of Infrastructure‑as‑Code concepts using tools like Ansible
• Proficiency with Git for source control

Desired Skills

• Experience with SQL databases, especially PostgreSQL
• Familiarity with Atlassian tools such as Jira and Confluence
• Comfort working in agile, mission‑focused development environments

Compensation Range: $179,000.00 - $237,000.00
