Role
Who you are
- We’re looking for an experienced Full Stack Engineer with 3 – 5 years’ experience to play a key role in shaping and building our product
- Proven experience (approx 3 - 5 years) building production web applications, ideally using Vue.js as your front-end framework
- Experience working across the stack (with Python / Django REST Framework being a definite advantage)
- Good knowledge of unit and integration testing and tools like Cypress
- Exposure to AWS (especially serverless / Lambda) or similar cloud platforms
- Comfortable owning projects and making pragmatic technical decisions. You assess different architectural design choices and seek input from others, using diagrams appropriately
- Strong communicator who enjoys working cross-functionally. You enjoy direct feedback from stakeholders and doing demos to team / company
- You are constantly curious, looking to improve your craft and engage in team tools and processes to help us operate as a high-performing team
What the job involves
- Reporting to our Head of Product Engineering, you’ll work primarily on our Vue.js frontend while contributing across our full stack - delivering features used daily by tenants, landlords and agents managing their tenancies
- This is a high-ownership role in a small, ambitious team. You won’t just ship tickets - you’ll shape solutions, influence product direction, and help us level up how we build software
- Lead development of high-quality, performant frontend features in Vue.js
- Contribute across the stack (Python / Django, Node/TypeScript, AWS Lambda)
- Take ownership of projects end-to-end — from idea and design to delivery and iteration
- Collaborate closely with Product, Design, Commercial and Customer teams to build solutions with measurable business impact
- Improve our frontend architecture, design system, and engineering standards
- Actively improve our development processes, tooling and CI/CD practices
Salary benchmarks
Our take
The average rental deposit in the UK is over £1000, an amount that many tenants struggle to pay when moving home. Flatfair's answer to this is offering a non-refundable membership-fee equal to one-quarter the cost of a rental deposit, meaning renters don't have to take on credit card debt or borrow from family and friends to fund a deposit.
Other companies such as Goodlord and Movebubble have also tried to disrupt rentals, but it remains a hard space to crack. That said, Flatfair's approach, in which it becomes pivotal to both landlords and tenants, puts the company in a smart position to streamline processes and improve the experience, and certainly makes it an intriguing prospect in the space.
The company recently rolled out a tenant guarantor product across 1,000 Build-to-Rent homes in partnership with Heimstaden, combining it with its existing no-deposit solution to simplify tenant onboarding. As the UK rental market evolves and new regulations such as the Renters' Right Act approach, platforms that reduce friction for both renters and landlords could become increasingly important.
