ABOUT NOUS Over 85% of households overpay on their bills. Our mission is to make people’s lives simpler and fairer, starting with the 30 million households here in the UK, and eventually, far beyond. Nous is the solution to this huge but often overlooked problem. We save our users serious money - Rob https://www.nous.co/blog/saving-stories-how-rob-saved-more-than-ps800-with-nous, saved £1,030/yr, Christian https://www.nous.co/blog/savings-story-how-christian-saved-ps950-on-his-bills-with-nous saved £950/yr, and we have thousands more just like them. They give us rave reviews and our Net Promoter Score is consistently in the high +80s. We’re frequently featured on TV https://www.youtube.com/watch?v=FcworaBwyvI and in print with our views on cost-of-living consumer issues. We’ve built Nous as an AI-powered assistant that helps households manage and delegate managing their bills, saving them money and time. What we’re building looks elegantly simple to the user, but under the bonnet it’s one of the most ambitious consumer AI systems in the UK. We’re not iterating on someone else’s playbook; we’re writing a new one. If you want to work on something obvious or easy, this isn’t it. We’re a well-funded start-up led by experienced entrepreneurs that’s growing extremely rapidly. We’ve helped over 150,000 people since the cost-of-living crisis started. We’re a B Corp, formally accredited for our commitment to exceptionally high standards of social and environmental performance, transparency and accountability. We’re proud of our social impact. Since launch mid-last year we’ve been rolling out our service through a variety of channels - direct to consumers and also via employers who want to help their teams hang on to more of their hard-earned cash by using Nous. We are now growing over 10x year-on-year (~30% month-on-month), and have saved our customers over a half-million pounds over the last few months alone! It’s not easy. We move fast, think deeply, and hold ourselves to high standards. We’re proudly office-first (based near Farringdon station) because we believe high-context collaboration helps us build better. The kitchen’s well-stocked, the coffee’s excellent, and so is the team. So if you are brilliant and want to build something amazing that changes the world, get in touch. THE ROLE Millions of households overpay on their bills every day – not by accident, but by design. At Nous, we’re using AI and deep market expertise to flip that system: taking the firepower big businesses have had for years and putting it in the hands of everyday households. We’re looking for a Product Engineer who wants to weaponise their skills for good. You still love to code, you think from a product-mindset, and you’re not satisfied until we’ve actually saved a family money and stress. This is not a role for someone who wants to sit quietly in a corner and complete tickets. We're looking for exceptional individual contributors who wants to raise the bar: excited by hard technical problems, but pragmatic enough to know when “simple and shipped” beats “perfect and late”; someone who instinctively spots risks before they blow up, and still gets a kick out of writing clean, scalable, well-tested code. We’re building one of the most ambitious consumer AI services in the UK. That means fast iteration, end-to-end ownership and lots of agency. You’ll be a hands-on technical leader on some of the highest-leverage areas of our codebase, from building out agentic capabilities to scaling our service logic. Within your first few months, you might: - Design and ship an agentic flow that takes a messy bundle of bills from a member, classifies them, extracts key terms and recommends a better set-up. - Build an internal tool that turns a 10-step Ops process into a 2-click workflow, saving the team hours every week and letting us scale to many more members without growing headcount linearly. - Lead a spike on a new integration with a major provider’s API, handling flaky responses and edge cases gracefully while keeping the member experience fast and simple. - Work with Product and Data to define a metric that actually captures “household peace of mind”, then ship experiments that move it, not just vanity engagement numbers. You’ll report directly to the CTO, so you’ll be in the room for key architectural and product decisions – not getting them handed to you after the fact. We’re deliberately light on layers of management: exceptional individual contributors shape direction by solving hard problems. As part of our passionate cross functional team, you will: - Take the lead on projects within a high-context engineering team. - Actively contribute to product strategy and wider company goals, not just implementation details. - Help shape how our engineering team grows and the technology we use. - Promote best practices and a collaborative, low-eg
