Full job description

Founded in 1998, Octasic is a privately held company headquartered in Montreal, Canada, with Research and Development facilities in Canada and India and a global sales support network. Octasic is a leading provider of SoCs (System on Chip), software and hardware integrated platforms for the global wireless and multimedia gateway markets. Our hardware and software platforms are the foundation for next-generation wireless systems for Defense, Law Enforcement and National Security Agencies.

We choose Octasic for:

A workplace at the cutting edge of technology to be in contact with wireless technology experts in a growing company;
Competitive compensation (salaries, benefits, gym membership discount, stock options purchase program, public transit reimbursement, shower on the premises and beverages and snacks free every day);
Work-life balance;
Friendly and collaborative work atmosphere and many social activities all year long;
Working for a company involved in its community;
Proximity to various public transportation services (Angus Shuttle, 10 min. walk from Prefontaine station).

About the role:

We are seeking a highly skilled and versatile Senior 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;
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 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:

Familiarity with JavaScript, TypeScript, and modern web frameworks (e.g., Vue.js, React);
Understanding of responsive and adaptive UI principles;
Experience contributing to front-end components or web-based tools used to interface with embedded systems.
