Don’t mistake us for a typical corporation. We are not looking for just a team member, we’re searching for someone to enrich our family. We will let you write the code and bring your ideas. We will believe in you and give you creative freedom to allow you to do the best work of your life. Sounds familiar? Perfect! We’ve got what it takes to keep you feeling challenged and empowered.

Here’s a little song we wrote about you: You have worked on large projects and your background is in Java or in any other object-oriented language (PHP or Python). You’re a natural-born problem-solver and always game to develop products that solve real-world problems for customers around the globe.

You enjoy learning things that you’ve never touched before. This is your chance to intimately collaborate with a small team, to take on big projects that greatly improve the product. We love critical thinkers who like to question why we do things this way and want to do better.

Change agents are everywhere at Lightspeed, are you one of them? That comes with taking ownership of the code you write, coupled with strong architectural skills. If you want to do the best work of your life while being surrounded by talented colleagues, we think we should talk.

Now we get to brag about us: Lightspeed provides retailers and restaurateurs the simplest way to build, manage, and grow their business while crafting a better customer experience. Lightspeed empowers small business owners with a complete overview of their business in one place - more than 50,000 businesses processing over $15 billion in transactions use.

Founded in 2005 with offices in Canada, USA, and Europe, Lightspeed is backed by Accel Partners, iNovia Capital, Caisse de dépôt et placement du Québec (CDPQ), and Investissement Québec (IQ).
