Who we are

At Kato, we’re not just building software, we’re transforming how commercial property operates. Our all-in-one platform powers the UK’s top real estate firms, helping them work smarter, faster, and more transparently with rich industry data and AI-backed tools. Backed by top-tier VCs and already used in 80% of the UK commercial real estate market, we’re scaling quickly and we’re just getting started.

We’re now looking for a Mid-Level Laravel Developer to join our tight-knit engineering team. In this role, you’ll work across our Laravel + React stack to deliver new features, optimise performance, and help shape the foundations of a platform used daily by thousands of property professionals.

If you’re passionate about writing clean, scalable code, solving real-world problems, and want to grow your skills in a high-impact startup environment, you’ll thrive here.

The Role

We’re looking for a mid level Laravel Developer to join our small but mighty product team. You’ll be working across the stack to build new features, ship improvements, and make sure our platform is scalable, secure, and a joy to use.

This is a hands-on role where you’ll be coding daily, collaborating with product and design, and owning features end-to-end, from scoping, to building, to deploying to production. You won’t just be “a cog in the machine” , you'll have the freedom and responsibility to shape our product from an early stage.

What You’ll Be Doing

• Full-Stack Development
• Build and maintain core features of our platform using Laravel (backend) and React (frontend).
• Write clean, maintainable code that balances speed and scalability.

Collaboration

• Work closely with our Product Manager and Designer to scope projects and deliver features users love.
• Give input into technical decisions and suggest improvements to how we build.

Hands-On Problem Solving

• Debug tricky issues, optimise performance, and keep the platform fast and reliable.
• Integrate with third-party APIs and tools as we expand functionality.

Continuous Improvement

• Follow best practices (testing, security, clean code) while staying pragmatic in a startup environment.
• Help us evolve our stack and processes as the company scales.

Core Technical Skills

• Strong experience with Laravel (8.x or later) and its ecosystem (e.g. Passport, Horizon, Pint).
• Solid knowledge of React and modern JavaScript (ES6+).
• Experience working with relational databases (MySQL/PostgreSQL) and ORMs (Eloquent).
• Building and consuming RESTful APIs.
• Familiarity with Git and modern CI/CD workflows.
• Understanding of security best practices (CSRF, XSS, input validation, etc.).

Nice-to-Haves

• Experience with caching (Redis), queues, or performance optimisation.
• Familiarity with testing frameworks (PHPUnit, Jest, etc.)
• Exposure to event-driven architectures, microservices, or real-time features.
• Previous startup or early-stage product experience.

What Success Looks Like

• You’re consistently shipping features that improve the product and deliver value to customers.
• You’re comfortable working across the stack and jumping into backend or frontend as needed.
• The team trusts you to take a feature from idea to production with minimal hand-holding.
• You’re proactive in spotting improvements and contributing ideas to make the product better.

What’s In It for You

• Competitive salary + early startup equity potential.
• 25 days holiday + birthday off + duvet days.
• Flexible hybrid working (3 days in our Soho office, the rest WFH).
• Private healthcare.
• A chance to shape one of PropTech’s most data-rich platforms from the ground up.
• Snacks, drinks, and plenty of team socials in our central London office.

So if you’re a builder who loves Laravel and React, thrives in a fast-moving startup, and wants to have a big impact on a product that’s changing an industry we’d love to hear from you!
