About Cinnamon
👋 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.
Our first AI hire is already live with agencies across the UK.
What you will do
- Develop and maintain critical integrations connecting Cinnamon to external systems using Python, TypeScript, and event-driven architectures.
- Take full ownership of technical customer issues, diagnosing bugs in production and shipping code fixes to resolve them permanently.
- Manage data modelling and query design across PostgreSQL and Redis while deploying services on GCP and AWS infrastructure.
Who this is a fit for
- Holds a Computer Science degree completed within the last two years and possesses at least one year of professional software engineering experience.
- Demonstrates proficiency in modern development tools like Python or JavaScript and is eager to master a full-stack, cloud-native environment.
- Communicates clearly with customers and colleagues, showing a strong desire to solve complex technical problems with a product-focused mindset.

Why this role is remarkable
- Get hands-on engineering experience across the entire stack, from Python and FastAPI backends to React and Next.js frontends, starting on day one.
- Work in a high-intensity, collaborative environment five days a week in a central London office alongside the founding team.
- Bridge the gap between product development and customer impact, gaining a deep understanding of how users interact with live systems.
