About the role:

We are seeking a highly skilled and versatile Software Developer with at least 10 years of professional experience. This role is ideal for someone with a strong background in embedded systems and mission-critical software, who enjoys working close to the hardware layer while contributing to robust back-end architectures.

As a Senior Developer, you will work closely with product teams and customers to design, build, and maintain scalable, reliable systems. Your focus will be on back-end and embedded software development, though experience with or interest in front-end technologies is considered an asset.

What you'll do:

• Collaborate across teams to translate product and business requirements into robust technical implementations;
• Design, develop, and maintain mission-critical back-end and embedded systems;
• Write and maintain unit tests to ensure code quality and prevent regressions;
• Participate in code reviews, architecture discussions, and delivery processes;
• Assist in system validation, debugging, and troubleshooting of complex issues;
• Mentor junior developers and promote best practices in software design and maintainability;
• Engage professionally with customers and stakeholders to ensure satisfaction.

Qualifications:

• Bachelor’s or Master’s degree in Computer Science, Software Engineering, Electrical Engineering, or a related field;
• 5+ years of experience in software development;
• Strong hands-on experience with C++, including work on embedded systems and mission-critical applications;
• Eagerness to learn and work with Rust (experience with Rust is a plus);
• Solid understanding of embedded systems, real-time constraints, concurrency, and software architecture;
• Proficiency with unit testing frameworks and methodologies;
• Strong communication skills and the ability to work independently or collaboratively;
• Eligible to obtain a Canadian security clearance;
• Willingness to participate occasionally in front-end development tasks, such as contributing to user interfaces that interact with embedded systems.

Nice to have:

• Understanding of responsive and adaptive UI principles;
• Experience contributing to front-end components or web-based tools used to interface with embedded systems.
