Job Description

About Us:

Fifth Dimension is bringing vibe working to document-heavy industries 🌈. Today we work with real estate businesses in the UK and US, automating complex tasks, extracting valuable insights from documents, and empowering professionals to focus on high-impact work. Our AI workspace transforms how large investment managers and developers handle leases, development documents, and investment decisions.

We're a London and New York based startup with an ample runway, backed by Tier 1 European and American investors. Our founders, Johnny Morris and Dr. Kate Jarvis bring a powerful blend of expertise (and spice 🌶️): Johnny has 17+ years applying data and analytics to Real Estate, while Kate holds a Stanford PhD and 12 years of executive experience across Silicon Valley and London startups.


At Fifth Dimension, we're demanding yet encouraging, valuing experimentation and kind challenges. Our company values, Own It, Ship It, and Don't Be Boring, drive us to deliver exceptional results while fostering a culture of innovation and continuous improvement.

The Challenge

It's Wednesday afternoon. You've just implemented a new React component that helps real estate investors instantly compare yield metrics across their portfolios. Using Cursor's AI-assisted coding and v0's rapid prototyping tools, you transformed complex financial data into an actionable, intuitive interface. A real estate investment director emails you: "This is exactly what we needed. I can now spot underperforming assets in seconds rather than hours." By Friday, you're sitting with another customer as they use your interface to make a multi-million dollar investment decision, watching them navigate effortlessly through data that previously required days of analysis spread across multiple spreadsheets.

At 5D, this isn't fantasy—it's how we transform complex document workflows into elegant digital experiences.

About You

You're a versatile developer who cares deeply about creating functional, intuitive interfaces that solve real problems. You understand that the best technical solutions prioritise usability and practical value over superficial aesthetics.

You've honed your frontend skills through practical experience with modern frameworks like React, and you have a talent for translating complex data into interfaces that make sense to non-technical users. On the backend, you can confidently write clean, maintainable code that powers these experiences.

You thrive in environments that encourage rapid experimentation and iterative development. You're comfortable with ambiguity and enjoy the process of quickly testing ideas, gathering feedback, and refining solutions. You're eager to learn new tools and techniques, constantly expanding your skillset to solve problems more effectively.

You're passionate about your personal growth as an engineer and see each project as an opportunity to develop new capabilities. You seek out challenges that push you beyond your comfort zone and value environments where you can learn from experienced colleagues.

You're not just a coder—you're a problem-solver who can translate customer needs into technical solutions that make their work easier and more productive, even without the guidance of dedicated UX or product teams.

Your Impact

As our Full-Stack Developer, you'll be essential in creating the interfaces and experiences that make our AI capabilities accessible and valuable to users. You'll work closely with our engineering team, solutions specialists, and commercial colleagues to build features that transform how real estate investors analyze documents, make decisions, and manage their portfolios. You'll own the complete lifecycle of features from initial customer conversations through design, implementation, deployment, and adoption.

Day to Day, You Will
  • Create usable, useful interfaces using React, leveraging component libraries like Shadcn UI to build practical tools that solve real customer problems

  • Focus on functional UX that makes complex data accessible and actionable for real estate professionals

  • Develop backend APIs and services in Python that power our frontend applications and process document data

  • Own end-to-end delivery from initial concept to production deployment and customer adoption

  • Collaborate with solutions and commercial teams to understand customer needs and translate them into technical solutions

  • Rapidly prototype and iterate on features, using tools like v0 and Cursor to quickly test ideas and refine based on direct customer feedback

  • Apply our engineering philosophy: intellectual honesty, effective time management, clear communication, and innovation

  • Participate in code reviews to maintain high quality standards and grow as a developer

  • Experiment fearlessly with new approaches and technologies, learning from both successes and failures

  • Invest in your own growth by taking on challenging projects and expanding your technical skillset

A Recent Success Story

One of our developers noticed real estate investors struggling to extract and compare key financial metrics from property documents. Using Cursor to leverage AI-assisted coding and v0 for rapid prototyping, they built an interactive dashboard in just four days. With Shadcn UI components and React, they created a visualisation that automatically extracts ROI, cap rates, and maintenance costs from hundreds of documents. Real estate investors can now instantly compare investment opportunities that previously took days to analyze manually. The feature went from concept to customer favourite within a single sprint, becoming a key selling point for our largest RE investment firm clients.

You'll create similar success stories that bridge technical capabilities with user needs.

What We're Looking For
  • Proven track record of shipping real products and features to customers

  • Strong frontend skills with React and component-based architecture

  • Experience with modern UI libraries (Shadcn UI, Tailwind CSS, or similar)

  • Solid foundation in JavaScript/TypeScript and CSS

  • Working knowledge of Python for backend development

  • Experience building and consuming RESTful APIs

  • Commitment to writing clean, maintainable, and well-tested code

  • Strong communication skills and ability to collaborate with cross-functional teams

  • Product-minded approach to development, with focus on user impact

Nice to Have (But Not Required)
  • Experience with state management solutions (Redux, Zustand, Context API)

  • Knowledge of GraphQL or WebSocket implementations

  • Background in data visualization libraries (D3.js, Chart.js, etc.)

  • Experience working in agile development environments

  • Familiarity with document processing or AI-enhanced applications

  • Experience in real estate, law, or finance industries

Our Values

We live by three core principles: Own it, Ship it, and Don't be boring. If you're excited about building intuitive interfaces that make complex document workflows simple and enjoyable, we want to hear from you!

Our Engineering Culture

At 5D, you'll join a team that values:


  • Product-Minded Engineering: Understanding the "why" behind features and using technical expertise to inform product decisions

  • Intellectual Honesty: Backing discussions with data and acknowledging knowledge gaps

  • Effective Time Management: Setting clear timeboxes and abandoning approaches that aren't working

  • Clear Communication: Writing self-documenting code and providing detailed explanations in technical discussions

  • Innovation Mindset: Forming well-reasoned opinions backed by data and continuously learning

  • Personal Growth: Supporting your development through challenging work, knowledge sharing, and opportunities to expand your skillset

What we offer you
  • £70,000-£110,000 salary per annum 💷
  • Meaningful equity (on a standard vesting schedule) 📈
  • A shiny new laptop and budget for other gear of your liking 💻
  • An opportunity to work with cutting edge technologies ⚠️
  • An opportunity to wear many hats, and grow with the business 🤠
  • Well being budget to promote your physical, mental, and emotional health ❣️

Interview Process


  • Submit your CV, along with answers to the handful of questions we ask of every candidate
  • A call with our CTO to explore the initial fit
  • A live task and competency interview
  • An in person culture fit interview with a range of people across the business, including the 2 founders

Job Description

Starling is the UK’s first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Starling is the UK’s first and leading digital bank on a mission to fix banking! We built a new kind of bank because we knew technology had the power to help people save, spend and manage their money in a new and transformative way.

We’re a fully licensed UK bank with the culture and spirit of a fast-moving, disruptive tech company. We’re a bank, but better: fairer, easier to use and designed to demystify money for everyone. We employ more than 3,000 people across our London, Southampton, Cardiff and Manchester offices.

Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do. Help is never far away in our open culture, you will find support in your team and from across the business, we are in this together!

The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person. We don't like to mandate how much you visit the office and work from home, that's to be agreed upon between you and your manager.

Our Data Environment

People with a broad ability to apply themselves to a multitude of problems and challenges, who can work across teams do great things here at Starling, to continue changing banking for good.

Requirements

We have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
  • Believe in clean coding, simple solutions, automated testing and continuous deployment.
  • Like to take ownership of a feature from the original idea through to live.
  • Think (like us) that a small number of empowered developers is the right way to deliver software.

Interview Process

Interviewing is a two way process and we want you to have the time and opportunity to get to know us, as much as we are getting to know you!
