About Us  Air-tek is a Canadian-based software company redefining how airlines operate through intelligent automation and modern, scalable systems. Our suite of products has already captured a significant share of a massive global market - and we99re only in the early innings.
While our customers know our name, we intentionally operate in stealth mode as we continue to build, innovate, and scale globally.
We99re a team of  builders, problem-solvers, and innovators  passionate about making airline operations seamless, data-driven, and passenger-centric.

You
99ll play a key role in shaping the architecture, design, and development of core systems that touch some of the most complex processes in global aviation. Whether it99s scaling integrations, designing robust APIs, or optimizing performance across distributed systems, you
99ll have the opportunity to  own features end-to-end,  and ship work that matters.

Exposure to  databases  like MySQL or Mongo

DB, and comfort working with message brokers (e.g. Rabbit

MQ).
You think in systems - how things fit together, scale, and impact users.
You thrive in fast-moving environments, stay curious, and don
99t wait for direction.
Strong communicator and collaborator who enjoys solving problems as part of a team.
You take  pride in your work -  from the code you write to the value it delivers.
