About Nous

Nous is a household AI agent. It takes over the bills and admin people don't have time for and acts for them: switching energy, buying insurance, cancelling forgotten subscriptions, managing the family calendar. Nearly 250,000 UK households have signed up, and another joins every minute.

We think the real value of AI isn't writing amazing cover letters, it's doing useful things in the real world for real people. That's the hard part, and a brilliant product is only half of it. An energy switch takes weeks, so our agents run on long-running workflows, not a single chat turn. Cancelling a subscription means a browser agent handling the code Apple sends to your phone. Buying insurance meant getting our regulatory principal comfortable with an agent doing it end to end (a UK first), which comes down to knowing exactly when the LLM should hand over to rules because a mistake would cost someone real money.

We're about 30 people running one agent across energy, broadband, mobile, insurance, mortgages and subscriptions (with more being added), each with its own suppliers, rules and ways of going wrong. With far more problems than people, a person or small team owns each one end to end, from spotting it in the data or a customer conversation to shipping the fix. And because the agent acts, you find out quickly whether the fix worked.

Everyone builds here: a product engineer launched our subscription cancellation product within a couple of months of joining, and a PM rebuilt our WhatsApp agent.

And it's working. We're growing more than 20x year on year, with a market-leading NPS above +80, and we manage well over half a billion pounds of household spending. We've raised more than $30M from Heartcore, Mosaic and a who's who of entrepreneurs who founded Monzo, GoCardless, lastminute.com and Onfido. But the real draw is the team - ask anyone here why they joined and you'll get some version of "to do great work with really smart people".

The goal is household life that's simpler, cheaper and fairer, and most of that is still to build.

A note on product

 

There’s ‘product’ as in the web application that guides our users through the complex world of bills and household admin. It 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. Try it here: app.nous.co/signup (it’s free!)

 

Then there’s ‘product’ as experienced by our users - which is a service which makes life simple and fair. To deliver this we’ve built a set of powerful capabilities that let us run and improve the service efficiently at scale: agentic communication, multimodal data extraction, orchestration for long-running operational processes, recommendations, our own agentic harness, and more. We compose these into executable workflows that deliver real outcomes for members, like switching someone to a better energy deal without the hassle.

 

Behind the scenes, we’ve built the technology (we call it Blueprints) that acts as rails for us to quickly expand on the breadth and depth of our service lines.

 

The role

 

We already have strong Product Engineers who think own problems end-to-end.

 

Some examples of the types of problems product engineers solve here:

 

As a Staff Product Engineer, your job is to also multiply that: to pick and lead the big, often cross-team bets that change how well we help members; e.g., how quickly a new household goes from “I think I’m overpaying” to “Nous is handling it”, how many people actually get tangible value through Nous, and how little human effort it takes behind the scenes.

This is a hands-on individual contributor role, not a people-management role. You’ll spend most of your time in code, system design and product thinking - but at a scope that cuts across teams and directly shapes company direction. If you desire, there is also space and opportunity for growing into a people-management role down the line, as we grow.

 

How we build

 

We try to keep our stack simple & modern, while safe & boring in the right ways:

We ship to production daily, favour small, reversible changes, and keep a close eye on the user impact of what we ship.

 

What you’ll do

 

First and foremost, you're a Product Engineer (please review the description there). Beyond that, you will:

You’ll report directly to the CTO and work closely with Product, Ops, and rest of leadership. There aren’t many layers: how you frame problems and ship solutions will directly influence what the company does next.

 

What year one might feel like

In your first 6–12 months, you might:

Throughout, you’ll be shipping code regularly, not just writing docs or drawing diagrams.

 

How this role is different?

Compared with a Product Engineer, as Staff you:

If that step up in scope and leverage – while staying deeply hands-on – sounds like your sweet spot, you’ll probably enjoy this.

 

So, … is this you?

If this resonates and you can demonstrate it, we'd love to talk to you.

 

Remuneration and benefits

Compelling packages, including meaningful 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.

An environment where you can do your best work:

Nous has an office-first culture (i.e., at least 3 days a week, more context on it here). That means we encourage in-person working, and most people do work from the office in Farringdon most of the time. We do a lot of brainstorming, problem-solving and interaction within the team and presence makes this more effective. It also helps ensure people have good peripheral awareness and high context. But we are pragmatic not doctrinal about this, and recognise that some types of work can sometimes be done remotely.
