Senior Software Developer

Position Overview

We’re not looking for your typical behind-the-scenes developer.

At Calian, we're building MaestroEDE—a cloud-native, AI-powered exercise management platform used to improve the readiness of defence organizations—and we need a Senior Software Developer who’s as comfortable at the keyboard as they are in a conversation. If you’re a hands-on builder and a confident communicator who thrives in collaborative environments, this is your chance to shape a product that supports high-stakes training missions.

You’ll report directly to our Director of Emerging Technologies, work in a tight-knit team, and have real influence from day one. While this is a hybrid role based in Ottawa, we’re open to remote candidates across Canada who bring the right energy, skill, and presence.

🏆 Calian was recently recognized by TIME Magazine as one of Canada’s Best Companies (2025) and ranked #37 on Forbes’ list of Best Employers for Company Culture. This is a place where culture isn’t just a buzzword—it’s built daily by people who show up with integrity, creativity, and commitment.

Responsibilities

• Lead full-stack development with technologies like PHP, JavaScript (Node.js or modern frameworks), Python, and .NET
• Deploy and secure applications in Linux-based, containerized environments (Docker, Kubernetes)
• Build and optimize databases (MySQL, PostgreSQL, MongoDB)
• Own DevOps practices—CI/CD, observability, security, and automated testing
• Translate complex technical work into clear, engaging updates for stakeholders
• Collaborate with product managers, military SMEs, and internal teams to co-create solutions
• Prototype AI integrations using tools like OpenAI or Hugging Face
• Participate in meetings, give demos, and confidently represent development progress to varied audiences
• Support mentoring of junior developers and contribute to team best practices

Qualifications

• Post-secondary diploma or degree in computer science or related field
• 5+ years of experience in full-stack development
• Technical depth in Linux, PHP, JavaScript, Python, and/or .NET
• Proficient in cloud-native environments with Docker, Kubernetes, and major cloud platforms (AWS, Azure, or GCP)
• Strong communicator—able to explain ideas, host discussions, and connect with users
• Skilled in CI/CD tooling, Git workflows, and database performance optimization
• Comfortable taking initiative and balancing hands-on technical work with people-oriented collaboration
• Bonus: Experience with AI, defence applications, or user-facing product development

Additional Requirements

• Must be eligible to work in Canada
• Preference for candidates based in Ottawa or within commuting distance (hybrid)
• Remote work considered for the right candidate
• Travel may be required, including international travel
• A background check will be required, and the successful candidate must be eligible to obtain and maintain a Level II (Secret) security clearance

Who Thrives Here?
The best fit for this role is equal parts builder and bridge—someone who writes clean, scalable code but also leans into dialogue, demos, and user discovery. You’ll thrive here if you:

• Like working in a small, high-impact team
• Enjoy explaining “how it works” to non-devs
• Are curious about how your work connects to real-world outcomes
• Want to help define not just what gets built—but why

Let’s Build Something Bigger Than Code

At Calian, you’ll help shape a defence-grade, AI-enabled platform—and do it in a workplace recognized for exceptional culture, collaboration, and growth.

Apply now and help us reimagine how technology supports Canada’s mission-critical training.
