About Motion Motion is building the command center for creative strategists : an AI-native platform that bridges the gap between performance marketers and creative teams, so they can uncover what’s working, what’s not, and ship more winning ads across platforms like YouTube, LinkedIn, Meta, and TikTok.
We're at the forefront of AI as the foundation of our product. Motion now automatically analyzes and organizes creative at scale and surfaces competitor trends. And with Runneth - the AI brain for the 100x marketer - we're going further: a persistent creative strategy agent that lives where your team already works (Slack, Notion, Google Drive, your ad data) and turns a marketer's knowledge and instincts into cross-channel playbooks, automated workflows, and a system that gets smarter over time. Our bet isn't that AI replaces great marketers. It's that the best marketers will use AI to operate at a scale that wasn't previously possible.
Today, Motion is trusted by some of the world’s top e-commerce and direct-to-consumer brands and agencies (including Vuori, True Classic, The Farmer’s Dog, and HexClad) and has analyzed over $14B in media spend. When leading brands want to understand their creative performance, they turn to us.
A number of teammates chose to build again here — a reflection of the trust, culture, and conviction behind what we’re building.
The people building Motion are deeply embedded in where AI and our industry is heading, and obsessed with closing the gap between what's possible and what's actually shipping in product. We're a 75 person remote team backed by $65M+ in funding with a valuation that's nearly 3x'd in under two years. If you want to work on a hard problem, with people who've done it before, and a product that customers genuinely love - we'd love to connect!
This is a hybrid role in our Montreal office, three or four days a week. As a Software Engineer, you'll work on the core infrastructure behind Runneth:
the VM it runs on and the services that run inside it.
Platform (cloud infra, DBs, centralised services and APIs), Agent Runtime (the VM layer Runneth runs on, the applications inside it, our harness, and the primitives that the Runneth experience is built on), and Runneth itself (everything customer-facing). In Montreal you'll be sitting with a small tight-knit team of the engineers working on the Agent Runtime working AI-powered features that are core to the Runneth experience.
React, Node.js with Express, TypeScript, GraphQL, PostgreSQL, MongoDB, and Azure.

Working with the team to provide services and primitives that the Runneth user experience gets built on
Keeping our systems fast, reliable and secure: integrations, data at scale, performance, and the devex problems in-between.
Working on a small, high-ownership team that ships constantly.
AI coding as the default, while holding what the LLMs produce to the same standard as code you wrote by hand.
Lives in Montreal and wants to be in the office (close to Metro Mont-Royal) three or four days a week.
Product shipping experience, ideally in a small team where you owned the outcome
Interested in turning over stones, curious about stuff you’ve never done before.
Strong programming fundamentals and production experience in multiple languages. Agent Runtime runs on TypeScript, Node.js, and Rust. You’ve designed and shipped real systems and care about their architecture.
AI writes a lot of our code, so the job is engineering judgment, not output.
Exceptional communication skills, you can explain the architecture of something you shipped; You are able to translate technical issues into clear business impacts, and prioritise accordingly.
Bonus: you're comfortable with Linux and deep infra.
...and you'll be a strong fit if you align with these qualities:
Able to prioritise for real customer value rather than polishing every edge
Comfort thriving in a fast-moving startup where requirements are ambiguous, shift quickly, and clarity isn't handed to you, you create it.
You'd rather work remotely, or only come into the office now and then.
You're cautious or sceptical about AI, in general or as part of engineering. We're betting hard on agentic coding being the future; How AI fits into your day-to-day workflow
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.
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.
We closed out 2024 with a $30M Series B raise and solid 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, with fresh funding ($65M+ total capital raised), we’re building forward from that foundation, taking what we learned to market in a deeply AI-native way.
We use artificial intelligence (AI) in certain parts of our recruiting process at Motion, ranging from administrative and efficiency-focused support to, in some cases, conducting introductory interviews. Every AI interview is reviewed, and every hiring decision is made, by a (human) member of our team.
