Product Designer (UX/UI)

We’ve gone from 0 to 400+ customers in under 18 months, with strong signs of product–market fit and a big mission: to make heat pump installations faster, easier, and more scalable across the UK. Now we’re looking for a Product (UX/UI) Designer to join our team of 10 and drive the next phase of growth.

🌲 About Spruce

• Almost 20% of the UK’s carbon emissions comes from heating homes – there’s simply no way to make reach net zero without phasing out gas and oil boilers. Right now the only serious alternative is heat pumps, with their almost-magical ability to turn 1 kW of electricity into 3-5 kW of heat (🤯). But there’s a problem: the heat pump installation journey is slow, inefficient, and just so painful. This makes it really hard for existing installers to grow their businesses and puts off gas engineers from starting to do heat pumps. Perhaps most critically, it means you can’t currently offer a heat pump when someone’s boiler breaks.
• We’re fixing this. We’ve built a platform for heat pump installers to manage the whole installation journey from initial enquiry through to final compliance paperwork, freeing up their time to focus on what really matters: doing high-quality installations, providing great customer service, and scaling their business. Despite only getting started at the beginning of 2024, we’re having a massive impact on installation businesses, suppliers, and manufacturers across the UK: halving the time they spend on each job, doubling their sales conversion rates, and boosting their bottom line.
• Having now raised further investment, we’re in the process of scaling the team to massively grow our impact. We ultimately want to build an operating system for the whole home renewables supply chain. Picture a combination of ServiceTitan, Procore, and autoCAD and you might get a sense of where we’re headed…

Requirements

🥖 The Role

You’ll be central to our mission as we turn a historically slow and painful process into one that’s quick, intuitive and even enjoyable for installers. We’ve been design-led since the beginning ( see here ) but the challenge is only growing as our product becomes (necessarily) more complex. Day-to-day you’ll be:

• Making complex decisions feel effortless – Our platform handles everything from building physics calculations to fluid dynamics modelling to complicated compliance requirements, and we need it to feel effortless for all our customers.
• Designing across multiple touchpoints – You'll work on desktop design tools, homeowner-facing outputs, enquiry flows, and mobile survey apps (incl LiDAR), and collaborative workflows that work seamlessly across different user types (from 3-person local installers to national energy companies);
• Building systematic, scalable design systems – Creating robust, structured, and reusable components that work across platforms and for potentially low-tech users;
• Researching and validation - Partnering with product managers, customer success and sales to understand installer feedback, build quick prototypes to test and validate design decisions and uncover unexpected pain points;
• Collaborating closely with developers – Understanding data structures and technical constraints so your designs can be shipped quickly and work brilliantly from the get-go.

🫵 About You

We’re looking for a designer with 3+ years of product/UI design experience , ideally in a startup or fast-paced team. We'd love to speak with you if you are:

• A clear, systematic thinker who loves tackling complex flows;
• Comfortable with technical detail, even if it’s a new domain;
• User-obsessed; you enjoy solving real-world problems and making a tangible impact;
• Great with people and confident running research with customers;
• Proactive and self-organising, happy juggling multiple projects;

Bonus if you’ve worked on tools for field teams, low-tech users, or operational workflows.

Benefits

🌟 Our offer

• 💰 £50-90k salary, depending on experience.
• 🍰 Meaningful slice of equity (options) in the company.
• 🏖️ 33 days holiday and opportunity to work from abroad for another 30 days each year.
• 🏡 Hybrid working: 2–3 days in-person a week (London or Bristol), with full-team meetups every fortnight.
• 👨‍👩‍👧‍👦 Brilliant team to learn from and massive opportunity to grow.

🧑‍💻 Working at Spruce

• We’re currently a close-knit team of 10, split between London and Bristol. We spend 2-3 days each week working together in-person in both locations, and get everyone altogether every fortnight.
• You'll have genuine influence from day one. The best idea wins regardless of seniority. We expect you to challenge everything, ask "why?" multiple levels deep, and push back when something doesn't make sense.
• We want everyone to spend time with installers on-site, feel their pain points, then be able to rapidly suggest and implement solutions based on real feedback rather than assumptions. This is clearly particularly important for this role but you’ll be surrounded by a whole team who are also close to our customers.
• We move fast and ship imperfect things, learning from users rather than trying to perfect in isolation. When things break, we focus on how we fix it, what can we learn and never blame. You'll own your outcomes whilst knowing the team has your back.
• Feedback is constant, direct, and kind – we'll tell you when something isn't working and expect the same honesty (and empathy) back.
