Builder - AI Native

We're looking for someone to help build Ember's product. You'll use AI heavily, ship software, and work across the full surface area of a fast-growing company. Your background is less important than your ability to learn, build and hold yourself to a high standard.

We're building the future of public transport — convenient, affordable, connected and zero-emission. Our goal is to make it easier and more enjoyable to get from A to B with Ember than it is with your own car.

Ember is a tech company, not a traditional bus operator. We've built a platform that coordinates our entire operation – everything from monitoring vehicles and controlling chargers to selling tickets and calculating ETAs. This allows us to use electric buses more intensively than anyone else in the world, leading to a massive reduction in emissions. It also helps us provide a much better passenger experience, with innovative features like demand-responsive stops.

We’re still tiny, with a handful of routes and 98 buses. The challenge is to scale this 50x whilst staying lean, increasing efficiency and delivering an even better product experience. We’ve recently raised a Series A from some of Europe’s leading climate VCs and are looking for mission-driven individuals who want to get on board and help take us to the next level.

This is a broad, high-impact role where you'll work directly with the CTO and co-founders. We're a team of 10 in tech. There are no product managers, no layers of process, and very few handoffs. If something needs building, we figure out what it should be, build it, ship it and make sure it works.

We're serious about AI as a product development multiplier. You'll have access to frontier models from Anthropic, OpenAI and others, with generous usage limits. A typical day might involve you orchestrating several AI agents on parallel work streams while you focus on the decisions, design and quality. We expect you to experiment with new tools and techniques as the landscape evolves.

Being AI-native isn't a substitute for being good. You're accountable for what ships. That means tests, observability, careful review, and the ability to debug when AI gets it wrong.

We don't need you to come from a specific background, although we expect you to be familiar with how software is built. You might be an engineer who's developed strong product instincts, a designer who's learned to code or an ex-founder looking for something new. You might come from a completely different field and have taught yourself to build software. What matters is that you're genuinely curious about all the elements that go into a great product — design, engineering, critical thinking — and willing to stretch into unfamiliar ones.

You’ll work on a mixture of greenfield and brownfield projects. That could include:

• Developing a self‑serve checkout for coach hire bookings, letting customers design and update their own journeys and stops.
• Building a platform to manage our stationary battery storage systems, making sure we have enough power for services while bidding on energy markets and optimising when we charge up the battery.
• Creating a brand new design system and component library, and migrating our existing website to it.

At Ember, we support diversity across our team and customers. We work to ensure every employee feels respected and able to give their best, whether temporary, part-time or full-time. We’re happy to offer flexible working patterns where they make sense, are compassionate when it comes to time off and we offer enhanced maternity and paternity leave.

You’ll receive a salary of £40,000–£100,000 per annum, depending on your experience and skills, plus share options. You'll also have access to frontier AI models with generous usage limits. You'll be expected to work from our office in central Edinburgh most days — we value in-person communication — but there's flexibility around the odd day from home.

You should have a desire to get involved early in Ember's growth story, with a real…
