In-office 5 days a week, on-site. We need an engineer who can own technical systems end-to-end and thrive in a fast-paced, high-stakes environment.
What we're building: Our starting point is selling to real estate agencies, where we're replacing manual workflows with AI employees that handle tenant engagement, landlord outreach, compliance, and maintenance autonomously. It runs on spreadsheets, missed calls, and manual processes that haven't changed in 30 years. Nobody has built the definitive AI agent layer for real estate yet.
As a Full-Stack Engineer, you'll:
- Own backend, frontend, infrastructure, and deployment.
- Ship features from concept to production in days, not weeks/months.
- Debug production issues at 2am without hesitation, then ship the fix by morning.
You'll touch every layer of what makes our AI agents actually useful in production:
- The Python / FastAPI backend that orchestrates our agents.
- API integrations with property management and CRM systems.
- JavaScript / TypeScript frontend that operators and customers actually use.
Required skills:
- Python: Backend systems, scripting, data processing.
- TypeScript / JavaScript: Modern frontend development.
- React: Frontend framework.
- PostgreSQL + Redis: Data modelling, query design, async patterns.
- GCP/AWS: Production infrastructure, deployments, observability.
Additional qualifications:
- Track record building products from 0 to 1 or scaling at an early-stage startup.
- Portfolio demonstrating end-to-end project ownership.
- Hands-on with LLMs in production (orchestration frameworks, vector databases, evals).
- DevOps / CI-CD pipeline experience.
- 1+ years at a top-tier tech company.
We operate with YC startup culture in London. If you're optimising for work-life balance, predictable hours, or a slow pace, this isn't for you. Six days a week in the office sounds exhausting rather than energising.
Salary: £75K-£110K base depending on experience, plus meaningful equity.
Benefits include:
- Front-row seat to building the AI agent layer for a $1T+ industry.
- Small, fast, building something that matters.
- Private health insurance.
- Uber home when you're working late.
- DoorDash dinners in the office.
- Monthly home clean.
- Brand new MacBook.
Process: Quick chat with our Founder’s Associate, followed by a Technical Chat (30 min). Top talent moves quickly. We won't waste your time.
