Aldgate, London. In-office 5 days a week. Forward-deployed, with regular travel to customer branches across the UK.
We're hiring our Founding Implementation Engineer.
Every agency we sign runs on a different setup. Different CRM, phone system, lead sources and way of working. You'll be the engineer who connects cinnamon to all of it and gets each customer live on the date we promised.
You'll own the path from signed contract to launch day, and you'll be the first person customers turn to when something technical needs fixing. That gives our product engineers the space to build, and it makes you the reason customers go live fast and stay live.
What we're building
Property is one of the most important parts of people's lives. It's where you raise your kids. It's most people's biggest financial decision. And the experience of buying, selling, or renting one is still shockingly bad.
We live in a world where you can send money across borders in three seconds, hail a car with a tap, and have your entire medical record on your phone.
But when it comes to property? You're waiting for a call back from a branch that closes at 5:30. Your offer is being managed in a spreadsheet. Your tenancy renewal is stuck because someone forgot to send an email.
The infrastructure that powers how people find homes, move between them, and manage their biggest asset has barely changed in 30 years.
Nobody has built the definitive AI agent layer for real estate yet. That's what we're doing.
cinnamon.io is a platform of AI employees that handle the property transaction end to end.
- Backed by Entrepreneurs First and top-tier VCs (our first investor was an early investor in Canva)
- Live with agencies across the UK with early US traction
- Based in Aldgate, London
What you'll do
- Own every rollout. You'll handle the technical side of each new customer, usually a few at once.
- Build integrations. Connect cinnamon to the tools agencies run on: CRMs, lead sources, phone systems and messaging.
- Keep launches on track. Get what you need from customers and their vendors, from API access to user lists.
- Handle technical support. Find the root cause and fix it. Only pass real product bugs to engineering, with a clear repro.
- Make it faster every time. Turn repeat work into scripts, tools and docs.
- Close the loop. Feed what you learn in the field back into the product.
You'll be a great fit if
- You're a strong engineer. 2+ years shipping production code. Comfortable with [TypeScript/Python], APIs and webhooks.
- You love scaling problems. How do we onboard customers twice as fast? No, three times. No, 10x.
- You automate the manual. You turn operations processes into systems that take a quarter of the time.
- You're good with people. You can explain a technical issue to a branch manager in plain English.
- You're organised. You can run several launches at once without dropping anything.
- You're AI-native. You use tools like Claude and Cursor to move quickly.
- You take ownership. If a launch is at risk, you flag it early and fix it.
- Solutions, forward deployed or implementation engineering background
- Early-stage startup experience
- Customer or operational experience
This role isn't for you if
- You want to focus purely on core product. Our product team does that, and this role exists so they can.
- You don't want to work directly with customers.
- You need a perfect spec before you get started.
- You optimise for predictable hours or work-life balance.
How we work
We work hard. Five days a week in person. We're rebuilding a $1T+ industry and we don't think that happens on a 9-to-5.
We're also having fun. The team is sharp, ambitious, and enjoys the work. If this sounds exhausting rather than energising, this isn't the role for you.
What we offer
- Private health insurance
- Wellhub gym and wellness plan
- Dinners in the office
- Brand new MacBook
The real offer is ownership. You'll build how cinnamon gets deployed, from the first customer to the hundredth, and you'll shape the team that does it as we grow.
