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. Our founders have built successful companies before, including alongside several of the people now at Motion. 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 Brief overview of the Motion product & Runneth from our Co-Founder & CEO, Reza Khadjavi.

About The Role

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. Engineering at Motion is roughly three teams: 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.

Our tech stack

React, Node.js with Express, TypeScript, GraphQL, PostgreSQL, MongoDB, and Azure.

What You'd Be Doing

- Owning features end to end:



understand the problem, make the calls, build it
- Working with the team to provide services and primitives that the Runneth user experience gets built on
- Keeping our systems rapid, 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.

Our ideal fit brings

- 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; why you built it instead of buying it, what you'd change, and what happened when it reached users.
- You are able to translate technical issues into clear business impacts, and prioritise accordingly.
- Any background: self-taught, bootcamp, degree, founder. We love talent from everywhere
- Bonus: you're comfortable with Linux and deep infra.
- and you'll be a strong fit if you align with these qualities:
- A strong sense of ownership
- A pragmatic mindset
- Able to prioritise for real customer value rather than polishing every e
