Lead Mobile Developer

BIMM is booming, so we’re looking for a Lead Mobile Developer with deep iOS and Android experience to join our team. 

As we observe a hybrid model, this role will require you to be in office 2 days per week. 

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. 

This is an existing vacancy, not a made-up role — this one’s already got a desk waiting. 

Who we’re looking for  

You are a team player who can fly solo when needed. Although you have the full support of your teammates, you are able to lead the research and solution of 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. This role will directly support our client Audi and have the opportunity to shape the development of their digital platform.    

“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?
