Product Engineer

About Nous Nous is an AI-powered assistant that helps households manage their bills, saving them money and time. 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. Over 85% of households overpay on their bills. That’s the scale of the problem we’re here to solve and it’s hiding in plain sight. It’s also fiendishly complex. 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 backed by top-tier investors, led by a seasoned founding team and growing seriously quickly — more than 3,000% year-on-year. That makes Nous one of the UK’s fastest-scaling consumer start-ups. Since launch, we’ve helped hundreds of thousands of households get to grips with their bills - and we’re just getting going.

We’re immensely proud of what we’ve built so far. Our Net Promoter Score is consistently above +80, and our members (people like Lindsay , James and Vicky ) give us rave reviews. Now we’re scaling that experience to millions more people, making Nous feel less like another finance app and more like something that quietly sorts your life out in the background. The product might look like magic but making it work is anything but. Nous is intentionally lean, by design. We’re an AI-native company, not just an AI-native product.

Everyone here is expected to use AI to its full potential, whether that’s debugging a system, streamlining a workflow or improving how we serve customers. We don’t hire layers of middle management; we hire smart, high-agency people and give them real ownership. 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.

If you’re brilliant, ambitious and want to build something amazing that changes the world by improving people’s lives, get in touch.

The role We’re looking for a Product Engineer to join our team, who wants to weaponise their skills for good. We need you to help us build a world-class product that will be regularly used by millions of people across the UK. The product includes the web application that guides our users through the complex world of bills and household admin and acts as their interface to our management service, as well as all the behind the scenes capabilities needed to orchestrate and deliver that service - actually saving our users money and time.

As a product engineer, we empower you with context to enable fast iterations, 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. 

Although our stack is constantly evolving (and you can help shape that), here’s a current snapshot: Full-stack TypeScript (all the way from the database to the client), React, Postgres, and Temporal for long-running orchestration. Infra: AWS, Terraform, strong observability via Sentry and Datadog (full-stack, not just logs). Data: we lean heavily on Snowflake, Omni, dbt, Fivetran, Amplitude and Segment — and we’ve even built some of our own tooling to understand how well we’re helping our members. And we use Github, Linear, Graphite, and Blacksmith every day. We choose the best tool for the job, and don’t obsess around specific technologies.

You’ll report directly to the CTO, so you’ll be in the room for key architectural and product decisions. We’re deliberately light on layers of management: exceptional individual contributors shape direction by solving hard problems.

As part of our 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 environment. - Develop across the stack, building and operating both backend and frontend services, including resilient and robust integrations with third-party APIs.

About You If you read the following and feel a mix of “this is me” and “this would stretch me”, you’ll probably love being here.

- You’re here for the mission, not just the tech - You’re drawn to problems around fairness, money and complexity; and to making those things understandable and manageable for people around you. - You like seeing the impact of your work in real human outcomes: lower bills, less admin, fewer nasty surprises. - You’re picky about where you spend your time: if you’re going to work hard, you’d rather it be on something that genuinely helps people.

- You think like a PM, not “just” as an engineer - You’re happiest when you own a problem end-to-end: from a fuzzy user pain (“this renewal letter makes no sense”) through to a shipped solution and the numbers that show it worked. - You naturally ask “what’s the smallest thing we can ship to learn?” instead of waiting for a perfect spec. - You care about UX, copy and flow as much as correctness, because you’ve seen that a small wording change can make the difference between action and confusion.

- You’re a pragmatic full-stack builder - You’re comfortable working across the stack in modern Typescript, building robust backend services (Node/GraphQL/Prisma or similar) and polished UIs in React (or another modern framework). - You understand data flows and state management in web apps, and you’ve felt the pain when they’re not designed well. - You write clean, practical code that other people can understand and extend. - You know when to abstract, and when to keep it brutally simple to go fast.

- You bias to action and learn from reality - Ambiguity energises you. You can take a fuzzy problem, slice it into sensible bets and ship something real in days, not months. - You treat production as your ultimate feedback loop. Logs, dashboards and user behaviour are how you decide what to do next. - You’re happy to delete your own code when reality disagrees with your idea.

- You make the people around you better - You enjoy explaining complex ideas simply, pairing on gnarly problems and leaving things clearer than you found them. - You’re open, direct and kind: you can disagree without drama, and you care more about the right outcome than being right. - Over time, you want to grow your scope: shaping the stack, mentoring others and helping raise the bar for how we build product.

Nice to have (but not required) You don’t need to tick every box, but it’s a bonus if you have experience with the following: - Applying GenAI in very practical, user-facing ways, at the bleeding edge of the technology where you have to innovate rather than imitate existing solutions. - Orchestrating long-running workflows and complex integrations with third-party APIs. - Working with data pipelines and analytics to uncover new ways to save our members money and time.

Remuneration and benefits - Compelling packages, including share options with life-changing upside. We’ve raised enough money to pay real salaries. - We're building something great together and we all share in the upside. If we win, we win together.
