Hi! We're Bee Talents, an IT recruitment agency that has been helping clients from all around the world in building their technical teams since 2015. Today, we would like to invite you to participate in the recruitment process for one of our clients (currently on Stealth Mode).

Our client is a fast-growing AI-driven PropTech startup transforming the way homes are managed.

This AI agent will help clients with all things property-related - from finding an electrician or plumber to comparing home insurance quotes. Their platform will also digitise all information about a property to proactively manage maintenance and admin. The goal is to alleviate typical frustrations associated with property maintenance and repairs, thus improving marketplace efficiency and saving time and money.

Culture and the team: Team values bold thinking, end-to-end ownership, and transparent collaboration, where everyone is empowered to make an impact. The team is currently 9 people strong, including the CEO, CTO, CFO, UK Commercial Director, Head of Product, along with 3 founding engineers and a designer. With rapid growth ahead, they are actively expanding their team and looking for an engineering leader who will thrive in a startup environment.

Your tasks:
  • Own and drive the development of end-to-end features across React.js (web) and Python (FastAPI).
  • Ship high-quality, scalable, and performant solutions, ensuring seamless frontend-backend integration.
  • Work closely with Product and Design to turn ideas into polished, user-centric features.
  • Take full ownership of major features, driving them from ideation to launch, balancing speed and scalability.

  • Collaborate with fellow engineers (Frontend, Backend, and AI) to solve technical challenges and scale the platform.
  • Identify and remove bottlenecks in the development process to improve velocity.

    • What you’ll need:
  • 5+ years of experience in software engineering, including at least 1 year in a senior role, with expert-level proficiency in React.js and Python (FastAPI or similar framework).
  • Deep understanding of frontend performance optimization, API design, and scalable backend architectures.
  • Experience in fast-paced environments or startups, where rapid iteration and delivery are key.
  • Strong sense of ownership and a delivery-focused mindset—comfortable driving projects independently from start to finish.
  • Familiarity with best practices in testing, CI/CD, and cloud infrastructure.
  • Excellent problem-solving and communication skills, with a collaborative approach to working with Product, Design, and Engineering teams.
  • Fluent in English (B2+ minimum) for effective communication.
