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
