Original job description

Senior 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. Please note that while the need to apply is urgent, and initial confirmation may come within a week, the actual start date may likely be 3-5 weeks.

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 10 years of software development experience
Proficiency in Java and or C#
Experience working in secure or regulated environments (defence, public sector, or similar)
Solid understanding of software architecture, integration, and debugging

Assets

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, Science 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 (flexible)
Collaboration with internal colleagues, government, military, and contractor teams
Casual

How to Apply

If you are a SECRET-cleared software developer in the Ottawa area looking for meaningful, long-term work in the defence space, we encourage you to apply for this or for future consideration
