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

About the Senior Software Engineer role

As a Senior Software Engineer, you'll work across the stack: building features, designing and maintaining the APIs and services behind them, and increasingly building the AI-powered parts of the product.

Engineering at Motion is roughly three teams: Platform (cloud infra, DBs, centralised services and APIs), Harness (our agentic harness Runneth, the VM it runs on, and the primitives that the Runneth experience is built on), and Runneth itself (everything customer-facing). Where you land depends on what we need most when you start and where you’re able to contribute the most impact. What we do know: you'll be building AI-powered features across the product, and you'll own what you ship.

Our tech stack: React, Node.js with Express, TypeScript, GraphQL, PostgreSQL, MongoDB, and Azure.

and what it means for us to be building an AI product today.

What you'd be doing

- Scoping, designing, and shipping features end to end: understand the problem, make the calls, build it,own the outcome.
- Building AI features across the product, and the APIs and services that support them.
- Keeping our systems fast and reliable: 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 LLMsproduce to the same standard as code you wrote by hand.

Our ideal fit brings

- 7+ years of experience building and maintaining software with customer traction, and a track record of shipping things people use.
- Strong proficiency in a contemporary web stack. We run on React, TypeScript, and Node.js, but if you've shipped production code in something comparable, you'll pick ours up quickly.
- Real depth somewhere in the stack, you’re an expert at something. We'll ask you about an initiative or feature that you personally owned and built.
- Mastery of an AI-assisted development workflow - even if it’s going to change again next week.
- 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 contacted users.
- Exceptional communication skills, you are able to translate complex technical issues into clear business impacts.
- Any background: self-taught, bootcamp, degree, founder. We love talent from everywhere

...and you'll be a strong fit if you align with these qualities:

- A strong
