Middle Fullstack Engineer

Full Stack Engineer

Posted Date Feb 15, 2026 Employment Type Full-time Experience Level Mid-Senior level Location United Kingdom Annual Salary 187,450 GBP Category ** Programming ** Company **flatfair **

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.

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.

****What You’ll Do

• 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

**Our Tech Stack

** Our core web application is built in Python / Django, backed by Postgres, and powers the critical workflows used daily by tenants, landlords and agents across the UK. On the frontend, we use Vue.js to deliver responsive, intuitive experiences across both web and mobile, while our internal design system ensures consistency and maintainability as we scale.

Our infrastructure is hosted on AWS, using services such as Lambdas, SQS, SNS, S3 and Elastic Beanstalk to support a reliable, scalable production environment. We ship continuously via CircleCI and we take operational visibility seriously using Datadog / Sentry for performance monitoring, real-time error tracking and issue diagnosis.

From day one, you’ll be working on an actively used, revenue-generating platform supporting a growing and engaged user base. The features you build will run in a live production environment where reliability, performance and user experience genuinely matter. You’ll work on systems that people depend on to provide choice and transparency in the lettings industry.

We don’t expect deep experience in every technology listed but coverage across most of the listed systems or similar technologies is important for you to succeed.

**About You

**

• 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 Interested in remote work opportunities in Development & Programming? Discover Development & Programming Remote Jobs featuring exclusive positions from top companies that offer flexible work arrangements.
• 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.

**AI Engineering Culture

** We actively use AI as part of our development workflow, from code explanation, code generation and refactoring to test writing, debugging and architectural exploration.

We expect engineers to:

• Use AI tools to accelerate and enhance their output
• Critically evaluate AI-generated code
• Explore new AI-powered workflows that improve quality and velocity

We’re on an ongoing journey to raise our AI Software Engineering mastery so you will be given the scope to explore AI engineering tools and practices. This means you’ll also have the opportunity to help define how AI augments our engineering practices and shape how we use it in the product and across the company.

If you’re excited about gaining real AI development experience on real-world products and do this in a team that embraces AI rather than restricts it, this role is for you.

****Why This Role Is Interesting

******Real Product Ownership in a Small Team

** You’ll own meaningful features from conception to production. You’ll make architectural decisions, shape implementation, and see the direct impact of your work on real users. Time is critical for our business and we want to move quickly from idea to testing the market.

**Direct Impact on Business Outcomes

** The features you build have the potential to directly affect revenue, customer experience and operational efficiency. You’ll work closely with commercial and customer teams, understanding real-world problems and translating them into thoughtful technical solutions.

**Architecture Influence

** You’ll help evolve our architecture as we grow and expand with an exciting new set of products. We’ll need to consider how we scale to meet demand, extend our internal design system and improve performance and maintainability as the product grows in complexity. This is an opportunity to demonstrate genuine architectural influence.

**About Flatfair

** The lettings industry hasn’t evolved fast enough.

For tenants, it’s often opaque and financially restrictive. For agents and landlords, it can be complex, fragmented and inefficient. We believe renting should be built on transparency, choice and simplicity for everyone involved.

Flatfair is re-imagining how the rental ecosystem works. Since our beginning, we’ve built and scaled a product used by tens of thousands of tenants and partners across the UK, proving there’s a realistic choice for tenants. And one that protects landlords and reduces friction for all parties.

But we’re not a one-product company.

We’re now entering our next phase, expanding our platform and driving a new wave of innovative products, looking to add value at all stages of the lettings experience end-to-end. Our ambition is to become the technology layer that powers a fairer, smarter lettings industry.

In short, this is a pivotal moment for us.

We have strong foundations, a growing user base, and meaningful traction, but we’re still early in our journey. Engineers joining now will directly shape the direction of the platform, the architecture, and the products we take to market next.

If you’re excited about joining a company that’s building real momentum and bringing choice and transparency directly to the people, then this is that opportunity.
