BIMM are hiring a Senior Full Stack Developer (Contract)

BIMM is booming, so we’re looking for an experienced Senior Full Stack Developer (on a 6-month contract) to join our team!

Who we are    

BIMM is a Toronto-based agency that lives at the intersection of data, technology, and creativity to provide clients with high-performing campaigns and digital products that shape connected customer experiences. We’ve helped our clients implement fully integrated CRM customer journeys, built robust digital experiences, and created national loyalty programs with decades of experience in sectors of automotive, financial, telco and retail.  

We are creative realists, which means our ideas and solutions are grounded in the realities of our clients’ business. We believe big ideas are nothing without big results (and flawless execution); high-performing agencies deliver high-performing campaigns, products, and experiences; and the best solutions happen when we collaborate with clients as partners. 

Our Technology department is a 50+ person distributed team of Developers, QA, and Architects delivering amazing digital products on a leading -edge technology stack. 

This currently is a pipelining opportunity - updated timeline will be provided during interview process.

Who we’re looking for  

You use modern tools and frameworks (REACT and Node.js) and can code up an application from scratch and spin up a cloud infrastructure to host it.

You design systems that empower autonomous agents to interact, make decisions, and execute tasks seamlessly building both the application logic and the underlying cloud infrastructure needed to support scalable, dynamic agent operations. You have a clear understanding of security and build it into any of your services. Although you have full support of your teammates, you can participate in the research and solution to complex problems. At the same time, you know when to ask for help and don’t let pride or ego get in the way, because after all, you are part of a team. 

“Initiative” is your middle name, and you don’t give us a chance to chase you. We are on the hunt for people who have an innovative mindset (you still dream of that moonshot project but are currently working on your side -gig)! Is this you?
