Lead Full-Stack Engineer Introduction We are the UK’s biggest technology platform connecting customers and cleaners in the £5 billion house cleaning market. We help customers find trusted, local cleaners and assist those cleaners by finding them dense local customer routes, maximising their earnings and saving travel costs. We have built a strong foundation in the first eight years. We're the UK market leader – 3x bigger than the nearest competitor – and have delivered 1.5 million cleans with a 4.8 average rating. We've reached substantial turnover, growing at 50% each year, and we're already profitable with substantial cash to invest. Our core market is house cleaning in London, and there's a clear opportunity to grow our 1-2% market share by 5-10x in the coming years, building a business with a £100M valuation. We haven't built this position by luck. We've delivered this by being smarter than anyone else, by building innovative tech and by making the right decisions on repeat. Why we need you Disrupting the home cleaning market throws up a lot of hard problems: real-time scheduling, job- allocation, routing and messaging to coordinate thousands of daily home visits. And all this complexity has to be presented to our cleaners, customers and operations staff with beautiful, intuitive user interfaces. Our ambitions are much bigger than winning in a single vertical. We've built a platform from which we can not only tackle the £5 billion home cleaning market, but from which we can also address the £10 billion commercial cleaning and £40 billion tradespeople markets. We have already made promising starts in each of these new markets, and we plan to scale up our tech team with the very best engineers to supercharge our growth.
