Senior Software Engineer

Tucows has been on the Internet since people unironically called it the Information Superhighway. 

Today, we’re the second largest domain wholesaler in the world with over 14,925405 domains under management (OpenSRS / Enom). We’re doing all kinds of interesting things, including running an MVNO cell phone service (Ting) and building fiber to the premises networks in towns and cities across the US (Ting Internet). We offer individual and small business domains and integration with various popular platforms (Hover/Ascio and many more).

We’re a team of over 600 serving tens of millions of customers around the world. Our growth has been incredible, smart and measured (NASDAQ: TCX, TSX: TC). Our success is built on a solid technology foundation, thanks to the people that work with Tucows.

We work in real-time on live systems… so it requires a steady hand and a cool head. Anything that can go wrong will go wrong (we’re optimists… but we’re also realists) and that needs to be accounted for. We work primarily in Ruby on Rails and JavaScript/DoneJS stack.

The opportunity:
