Senior Product Engineer – Design & Interaction
£100k–£130k + equity | London | 4 days per week in office
Neulinx have partnered with a 15-person, Series A technology company building highly interactive tools at the intersection of creative software, collaboration and AI.
They’re looking for a senior Product Engineer who sits unusually close to design – someone who cares as much about how a product feels and behaves as how it is engineered.
This is a senior individual contributor role working closely with the CEO and product engineering team, helping shape new products and experiences from their earliest stages.
You might currently call yourself a Product Engineer, UX Engineer, Creative Technologist or Design Engineer. The title matters less than your ability to move comfortably between product thinking, interaction design, prototyping and production code.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What you'll be doing
- Taking ambiguous product ideas from early concept through prototype to polished product
- Designing and building sophisticated, highly interactive user experiences
- Creating high-fidelity prototypes directly in code
- Working closely with the CEO on new product concepts and design direction
- Building production interfaces using React and TypeScript
- Developing interaction patterns, components and broader design language
- Exploring new interfaces involving AI, creative tooling and unconventional interactions
- Working directly with engineers to turn prototypes into robust production experiences
- Having significant influence over how new products look, behave and feel
What we're looking for
- You’ll likely have substantial experience building digital products and be operating at Senior or Staff-level IC.

React and TypeScript are essential, but this isn't a conventional frontend engineering role. We’re particularly interested in people with experience across product design, interaction design, rapid prototyping, Figma, design systems, motion, animation or creative coding.
- Experience with areas such as canvas, WebGL, Three.js, multiplayer, collaborative software, developer tools, SDKs, AI agents or spatial interfaces would be particularly interesting, but isn't required.
Most importantly, you should be able to show examples where you've personally influenced both the design and engineering of a product, rather than simply implementing designs produced by somebody else.
