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 , 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.
