Spruce
Design Engineer
London, Remote. Posted 2 days ago
The role
You will own how Spruce's product looks, feels and behaves for installers, from first sketch to shipped feature. You will build and prototype flows, the component library, and hard-to-get-right tools such as the floor plan and system design canvas, the offline survey app and homeowner proposals.
What you will do
- Take flows from rough idea to production, prototyping quickly and testing with installers.
- Own the interaction layer: component library, motion, loading and empty states, touch targets.
- Build the canvas-based floor plan and system design tools, the offline survey app (incl. LiDAR), and the proposals homeowners see.
- Pair with and review the work of product designers and developers.
- Go out on site to watch how the product is used, then change it.
Required qualifications
- 3+ years designing and building product UI, ideally in a startup or fast-paced team.
- Shipped production UI you designed and built.
- Strong design craft and an appetite for code, with understanding of the code you ship.
- A prototyping instinct and comfort with imperfect work in front of users.
- Systems thinking, including component library structure.
- Curiosity about the domain: heating, solar and battery systems.
Nice to have
- React and TypeScript depth.
- Canvas/WebGL, animation, or complex state on mobile.
Benefits
- 33 days holiday (25 plus bank holidays).
- Opportunity to work from abroad for another 30 days each year.
- Private Medical Cover (Vitality).
- Workplace Nursery Benefit scheme (YellowNest).
- Enhanced Parental Leave.
- Cycle to Work scheme.
- Equity (options) in the company.
Before you apply
- The posting asks for five shared traits: curiosity, drive and work ethic, personal agency and ownership, humility and a growth mindset, and excellent craft.
