London | Full-Time | High-Impact AI SaaS
We're hiring a Lead AI/Python Engineer to join a fast-scaling AI SaaS company transforming property management across the UK.
This is a hands-on leadership role for someone who wants to architect systems, shape engineering standards, and build intelligent software used daily in a regulation-driven market.
The Company
A UK-focused AI platform automating compliance, maintenance, lettings, and tenant communications through an AI assistant capable of handling the majority of operational admin workflows.

- Lead code reviews and enforce engineering best practice
- Mentor engineers and raise overall technical standards
- Work closely with Product and Design to translate business needs into technical solutions
- Drive AI integration into production systems
- Ensure performance, security, and maintainability
This is not a maintenance role. It is system ownership.

- 7+ years commercial software engineering experience
- Deep Python expertise (FastAPI / Flask / Django)
- Strong system design and architecture capability
- Experience with cloud-native environments and Kubernetes
- Microservices and CI/CD exposure
- Proven experience leading projects or mentoring engineers
- Strong academic background (Computer Science or related discipline)
Nice to have:
- Production model deployment (HuggingFace / vLLM / Ollama)
- Model fine-tuning experience
- Open-source contributions
Why Join
- Competitive salary + equity
- Direct influence on product and engineering roadmap
- Work on applied AI solving real operational problems
- High ownership in a growing, product-led business
If you are a technically strong Python engineer who wants to lead from the front and build scalable AI systems in a real-world, commercially impactful environment, this is a strong platform to do it.
