Location: 1941 Robertson Rd, Nepean, ON K2H 5B7, Canada

Employment Type: Fulltime-Regular

Build bold. Deliver impact. Win together.

At General Dynamics Mission Systems Canada, we are not just engineering technology; we are shaping the future of defence and security. Our teams design and deliver advanced, mission‑critical solutions that enhance national security, strengthen communities, and protect the people we serve.

If you’re looking for meaningful work that contributes to a safer, more secure world, you’ll find purpose here. Every day, your skills will directly impact programs that matter.

We are seeking Junior Software Engineering Developers to support the design, development, integration, and testing of mission‑critical software and firmware used in land‑based defence systems. In this role, you will work within Agile, multidisciplinary teams on applied software engineering problems involving systems integration, embedded and firmware development, automated testing, and deployment in complex operational environments. You will contribute directly to production systems across the software development lifecycle, working alongside experienced engineers on real‑world capabilities.

This posting supports multiple junior software engineering opportunities beginning May 2026 and is well suited for recent or upcoming Engineering and Applied Science graduates.

In this role you may:

• Design, implement, integrate, and maintain software and firmware components and plugins for mission‑critical land defence systems.
• Develop software for embedded platforms, ARM processors, microprocessors, and Linux‑based systems.
• Design and implement user interfaces and features aligned with system requirements, including potential exposure to Android application development.
• Build and maintain automated tests (unit, integration, and system‑level) using Python and related frameworks; support lab and field verification.
• Configure, deploy, and maintain development, integration, and test environments (on‑premises, virtualized, or cloud‑based).
• Participate in Agile team ceremonies, including stand‑ups, sprint planning, reviews, and retrospectives.
• Collaborate with engineers across software, systems, hardware, test, and UX disciplines, as well as product owners and scrum masters, to deliver integrated solutions.
• Document code, design decisions, test plans, and integration workflows; participate in technical and code reviews.
• Analyze system behaviour, troubleshoot defects, and propose effective solutions.
• Identify opportunities for technical or process improvements and contribute to best practices.
• Explore and support integration of emerging technologies such as AI‑enabled tools, cloud platforms, and Dev Sec Ops  practices.
• Assist with system‑level testing, field trials, and integration activities; communicate updates and system behaviour to stakeholders.
• Build technical skills, expand domain knowledge, and actively contribute to team learning and knowledge‑sharing.

Required

• Bachelor’s degree in Software Engineering, Computer Science, Engineering Physics or a related discipline.
• Experience with at least one modern programming language (e.g., C#, Java, Kotlin, Python, or
  
  C).
• Strong problem‑solving and analytical skills.
• Excellent communication skills and ability to collaborate in a multidisciplinary team.
• Enthusiastic contributor, willing to learn new skills, and takes ownership of work.

Preferred

• Experience with Dev Ops or CI/CD tools and pipelines, including build and dependency‑management systems (e.g., Jenkins, Git Lab CI/CD, Maven, Gradle, Make, Docker, Kubernetes, Ansible, Terraform).
• Experience with automated testing frameworks and practices, including unit, integration, and system‑level testing (e.g., pytest, Robot Framework).
• Familiarity with software configuration management tools (e.g., Git, Git Lab, Rational Team Concert).
• Scripting and systems‑level development exposure, including Bash or Power Shell scripting, Linux command‑line usage, and embedded or firmware‑oriented environments.
• Experience with Android…
