Mid-Level Backend Engineer - PropTech Start-up
Summary
Build and own core CRM and finance systems for a fast-growing PropTech group using Python and FastAPI, with agentic AI workflows in a high-autonomy, lean engineering team.
Hybrid/Remote: London office, flexible days (1-2 per week)
This PropTech business is building a group of strong, locally-led property management businesses; acquiring and backing established operators, then giving them shared tech and operations infrastructure while preserving what makes each one work.
If you have Python + FastAPI experience working as a backend engineer who thrives in fast-growth environments, can own services end-to-end, and use agentic development workflows to ship faster, then read on! This role will see you work on the core applications powering the business!
Genuine roll-up story, still early: you\'d be building the CRM and finance systems that hold the group together, not maintaining what\'s already there.
Small, high-ownership engineering team; no legacy bureaucracy, no over-engineering culture. If you want visible impact on systems people actually rely on, this is that role!
What you\'ll do:
- Build and own production services in Python/FastAPI — not patch someone else\'s
- Ship fast using agentic AI tools (think Claude Code, Cursor) as core to how you work, not a bolt-on
- Operate with real autonomy in a lean team, end-to-end ownership of what you build
What you bring:
- Production Python + FastAPI experience = non-negotiable
- Scaleup DNA: you\'ve lived through a Series A/B (or comparable) growth phase and know how to ship under ambiguity
- Agentic dev workflows are already part of your daily practice, not something you\'re "trying out"
- You own your own testing and quality, no separate QA safety net required
