Senior Full Stack Developer

We are seeking a highly skilled and versatile Senior Full Stack Developer with 10 years of professional experience. This role is ideal for someone who has evolved from embedded and systems-level programming into full-stack web development and enjoys working across the entire stack--from back-end architecture to intuitive, responsive user interfaces.

As a Senior Developer, you will work closely with product teams and customers to design, build, and maintain scalable, mission-critical software systems. You will contribute to both client-facing front ends and robust back-end infrastructure, with a strong emphasis on performance, maintainability, and reliability in embedded and web-based environments, while ensuring customer acceptance and satisfaction.

Your daily life :

Collaborate across teams to translate product and business requirements into robust technical implementations. Design, develop, and maintain mission-critical back-end systems, including low-level and embedded applications. Build and maintain responsive front-end applications using Vue.js, React, Tailwind, CSS. Write and maintain unit tests to ensure code correctness, prevent regressions, and support long-term maintainability. Participate in code reviews, system architecture discussions, and delivery processes. Assist in system validation, debugging, and troubleshooting of complex issues. Support and mentor junior developers while promoting best practices in both embedded and web contexts. Good customer interfacing skills and a professional demeanor when engaging with stakeholders.

Required qualifications :

Bachelor's or Master's degree in Computer Science, Software Engineering, Electrical Engineering, or a related field. 10+ 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 in Rust (experience in Rust is a plus, but not required). Deep understanding of JavaScript, TypeScript, HTML5, and CSS3. Experience with responsive web design, including mobile-first and adaptive UI principles. Proficiency with unit testing frameworks and methodologies for both front-end and back-end code. Solid understanding of embedded systems, real-time constraints, concurrency, and software architecture. Strong communication skills and ability to work independently or as part of a team. The selected candidate must be eligible to obtain a Canadian security clearance.
