Intermediate Software Developer - Hybrid/Secret Cleared 90-110k
About the Opportunity
The Source Staffing is supporting a leading Canadian defence technology organization in hiring an Intermediate Software Developer / Engineer to join a mission-critical program supporting the Department of National Defence (DND).
This role is ideal for Secret cleared developers in the Ottawa region who are looking to apply their skills to operationally relevant systems used by the Canadian Armed Forces, specifically LC4ISR. You’ll be contributing directly to tactical command-and-control capabilities in a highly collaborative, Agile delivery environment.
Why This Role Stands Out
- Work on active DND programs with real operational impact
- Join an internal team deeply embedded in Canada’s defence and security ecosystem
- Stable, long-term program work (not short-term project churn)
- Collaborate with company colleagues; experienced engineers, CAF stakeholders, and system integrators
The Role
You will contribute to the design, development, and integration of tactical software applications, ensuring they meet the performance, reliability, and security requirements expected in defence environments.
This is a hands-on development role with exposure to system-level thinking, integration challenges, and real-world deployment considerations.
Key Responsibilities
- Design, develop, and enhance software systems within an LC4ISR framework
- Support system integration, verification, and validation activities
- Analyze and resolve system-level issues, including performance and interoperability challenges
- Collaborate with internal teams and external stakeholders to ensure system reliability and maintainability
- Conduct technical investigations into third-party software and integrations
- Review and contribute to technical documentation (interfaces, components, specifications)
- Support integration testing and evaluation activities in controlled environments
- Contribute within a SAFe Agile delivery model
Requirements
Required Qualifications
Must-Have
- Active SECRET security clearance (mandatory – must be valid and transferable)
- Minimum 5 years of software development experience

- Experience working in secure or regulated environments (defence, public sector, or similar)
- Solid understanding of software architecture, integration, and debugging
Assets
- Experience with Kotlin and/or Android development
- Working knowledge of C#
- Familiarity with MVVM architecture
- Front-end experience with Vue.js or similar frameworks
- Exposure to SQLite, Liquibase, or similar data tools
- Exposure to NATO standards or STANAG 4586
- Previous work on command-and-control (C2) systems or defence-related platforms
Education
- Degree in Computer Science, Engineering, IT, or related field
- Equivalent hands-on experience in defence or secure environments will be considered
Core Competencies
- Strong problem-solving and analytical thinking
- Ability to work effectively in cleared, multi-stakeholder environments
- Clear and professional communication skills
- Experience with automation, monitoring, and secure development practices
Work Environment
- Based in Kanata, ON, Hybrid, 4 days on-site (might be some flex here, maybe)
- Collaboration with internal colleagues, government, military, and contractor teams
- Business casual / casual
