A senior design engineer is needed to solve complex product-design challenges directly in the medium that ships to users. You will shape problems, make visual and interaction decisions, implement them in production, evolve design systems, and improve product quality across business-critical software.
Highlights
Own complex design problems end to end, from defining the problem through implementation and production validation. Strong emphasis on design systems, product quality, and close collaboration between design and engineering.
Description
This is not a Frontend Engineer with a new job title, and it isn't a designer who prototypes in code.
A Design Engineer designs in the medium the product actually ships in.
You'll prefer making visual and interaction decisions in the platform they'll be built in, because designing for the web in Figma duplicates effort when you're comfortable implement it too.
Our users are not browsing.
They are installers, engineers and office staff running a business inside Payaca all day.
That's the design brief: repeat-use business critical software where a saved click compounds hundreds of times a day.
What you'll do
Take our hardest design problems end to end: shape the problem, decide the design, build it, ship it, and watch how it lands in productionGrow our design system, balancing consistency with expanding requirementsMature our design system, enabling agents and devs to work efficiently across the productRaise the floor on quality across the product - the flows that work but feel like hard workDesign for different usage patterns with varying constraints: back office staff on desktop web, their customers on mobile web, and field engineers on offline first mobilePair with product engineers on the screens they're building, so taste spreads rather than bottlenecks on youUse agents to do the volume work - variants, sweeps, migrations - so your own time goes on judgementSet the patterns and the bar, through review and through the work itself
What we're looking for
4+ years shipping production frontend, strong in TypeScript, React and CSSVisual design taste you can point at - work you designed and built yourself, in the hands of real usersA track record of owning interface work from a vague brief through to production, resolving most of the ambiguity yourself3+ months getting real work done with AI coding agents, delegating meaningful chunks rather than autocompletingEnough range to follow a change past the UI when it needs API or data-model shape to work properlyA high bar for quality, and the discipline to never merge code you can't stand behind, whether you or an agent wrote itA healthy curiosity about clean-energy installers and the businesses they run
This probably isn't for you if
You want to work on the design system full time, rather than on the product with the design system as a meansYou need research and sign-off before you can start buildingYou need it perfect before it shipsYou need someone else to break the work down and sequence it for you
