Description
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.
What you'll be doing
Taking ambiguous product ideas from early concept through prototype to polished productDesigning and building sophisticated, highly interactive user experiencesCreating high-fidelity prototypes directly in codeWorking closely with the CEO on new product concepts and design directionBuilding production interfaces using React and TypeScriptDeveloping interaction patterns, components and broader design languageExploring new interfaces involving AI, creative tooling and unconventional interactionsWorking directly with engineers to turn prototypes into robust production experiencesHaving 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.
