Job description

AboutUs

We arebuilding 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.
Our founders have built successful companies before, including alongside several of the people now here. A number of teammates chose to build again here — a reflection of the trust, culture, and conviction behind what we’re building.

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.

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
• A track record of shipping things people use.
• Strong proficiency in a modern web stack. We run on React, TypeScript, and Node.js and TS proficiency is a must. But if your core skill is in another language, we can still chat.
• 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
• Exceptional communication skills, you can explain the architecture of something you shipped, and what you'd change with hindsight.
• , You are able to translate complex technical issues into clear feature and prioritisation with business impact. .
• 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 sense of ownership: you make decisions, stand behind them, and fix things quickly when they're wrong.
• A pragmatic mindset. 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.
• You enjoy being a strong individual contributor and a supportive teammate. Engineering is a team sport here!

You're probably not the right fit if

• You do your best work with structure: a defined spec, a predictable calendar, 2 week sprint cycles
• You struggle to context switch: You can only handle one focus at a time, switching between live issues and your work is frustrating, you tend to ignore Slack.
• You want a steady, predictable pace: a roadmap that is set in advance and stays the course.
• You're looking for a leadership role or a specific title
• You're cautious or sceptical about AI, in general or as part of engineering. We're betting hard on agentic coding being the future; if that feels like a mandate rather than an unlock, it won't be a fit.
