Full Stack Developer

Montréal, QC Full time $100,000 to $120,000 CAD annually About Lasso Informatics Research data is wild. It pours in from brain scans, genome sequencing, EEG and eye-tracking, biospecimens and wearables that track sleep and movement, across dozens of sites and years of study. Lasso Informatics ropes it in: our platform pulls it all into one place so researchers around the world can stop fighting with their data and get to discoveries faster. That is where our name comes from. A lasso brings something wild under control, and that is the job. The people who do it are Wranglers, and we are quite choosy about who earns the title. Wranglers expect a lot of themselves, make everyone around them better, and never stop learning. We move fast, we have fun, and we keep the bar high. About The Role We are hiring a Full Stack Developer to design, build and maintain the applications and services behind the platform. You will work across the stack, from frontend components to backend APIs to the database layer, building software that is secure, fast and stable enough for our collaborators to trust with their research data.
