Software Engineer jobs in Canada

Air-tek is a Canadian-based software company with a powerful suite of unique products that have already achieved a significant share of a huge global market. Our product‑market fit is strong, and customers are lining up to buy. Although our global customers know us, we intentionally operate in stealth mode during this growth phase.

Our diverse team shares a passion for solving complex problems with a drive to innovate and a vision to reshape the passenger‑centric travel industry. Based in Toronto, our inclusive culture is built on trust, collaboration, delivering a great product, and continuous personal growth. We love what we do, and we support the team around us.

We’re looking for a Staff Software Developer who can own big technical decisions, build scalable systems, and help shape our engineering culture as we grow. You’ll work across the stack, solve complex problems, and turn ambiguity into clear direction. This is a high‑impact role with broad autonomy.

• Architect and build scalable, high‑performance systems for aviation operations
• Define technical problem spaces and set engineering direction in ambiguous areas
• Lead team‑based technical decisions, standards, and architecture
• Drive long‑term technical strategy and de‑risk major initiatives
• Partner closely with engineering managers, product and design to ship software
• Mentor engineers and elevate team quality and velocity
• Act as senior on‑call escalation and lead high‑severity incident response

• 10+ years building production systems in the cloud
• Strong experience with C# / .NET Core (or similar back‑end tech)
• Proficiency with JavaScript/TypeScript and modern front‑end frameworks (React, Vue, etc.)
• Experience with microservices, performance‑optimized distributed systems, APIs
• Familiarity with MySQL/MongoDB and message brokers (e.g., RabbitMQ)
• CI/CD experience (GitHub Actions, TFS)
• Developer tooling or automation contributions
• Strong systems thinking, communication, and leadership in fast‑paced environments

• Work on meaningful problems that power the backbone of the airline industry.
• Build production‑grade software that scales globally and impacts millions of passengers.
• Collaborate with brilliant engineers in a high‑trust, low‑ego environment.
• Operate with autonomy and ownership – your ideas will shape our products.
• Exposure to modern technologies, cloud environments, and complex system design.
• Competitive compensation and growth opportunities in a fast‑scaling company.

Please note that this role requires three days a week in our Toronto office which is located near Union Station.

If you love solving hard problems, thrive in ambiguity, and take pride in building software that matters – we want to hear from you.
