• Proficiency with our core stack (React, Node.js, TypeScript) is ideal, BUT if you’ve worked with similar tech, we’d still love to chat.
• Excitement about using AI as part of your workflow and keeping up with how fast it’s changing how we build software.
• Experience with MongoDB or other document-based databases.
• Solid understanding of data modeling, ETL concepts, and simplifying data architecture.
• Exceptional written and verbal communication skills with a knack for translating complex technical issues into clear business impacts.
• and you'll be a strong fit if you align with these qualities:

You optimize for impact over perfection, care more about shipping real customer value than polishing every edge, and improve things over time.
Comfort thriving in a fast-moving startup where requirements are ambiguous, shift quickly, and clarity isn’t handed to you, you create it.
We offer competitive compensation, including equity for all employees, health benefits from day one, a monthly health & lifestyle stipend to support your well-being, 20 days of PTO, and a $1,500 work-from-home stipend.
Remote-first with hybrid flexibility : We're a remote-first company with team members spanning Canada, the U.and beyond, but also have office spaces in 4 main hubs (Toronto, Montreal, Vancouver, and Porto) for optional hybrid work.
Motion has strong product-market fit, 2.5x YoY growth, second-time founders with deep industry knowledge, and $30M in Series B funding to fuel our momentum.
If you're excited about building, you’ll thrive here!
We're a low-ego, high-performing team that was just ranked #19 on G2's list of Best Canadian Software Companies for 2026.
Virtual: Day-to-day, we use Roam, an AI-powered virtual office platform that fosters spontaneous collaboration, drop into meetings or quick chats, and interact with colleagues for a simulated, "live" digital headquarters.
Outside of the option to go to one of our offices, our team gets together in-person for a week every two months, and we have a company retreat every summer.

We closed out 2024 with a $30M Series B raise and strong signals from our customers. In 2025, we built the foundational capabilities our customers rely on, setting the stage for what's to come. In 2026, we’re building forward from that foundation, taking what we learned to market in a deeply AI-native way. Motion is a fully remote company, but we’re looking for someone in or around one of our hub cities (Toronto, Montreal, or Porto, Portugal) who can work with significant overlap to ET working hours.
