Job description

At Kato, we’re not just building software, we're redefining how commercial property works. Our platform powers the UK’s top real estate firms, helping them manage deals faster, smarter, and with total clarity. Backed by leading VCs and real estate experts, Kato is already used in 80% of the UK commercial real estate market and we’re just getting started.

We’re growing fast, building new product lines and unlocking new market segments. This is your opportunity to join at the ground floor of something truly transformative and in a team that values curiosity, creativity, and fast learning.

About the Role:

We're looking for a Junior Product Engineer to join our tight-knit product engineering team and help us scale Kato into a global platform. You’ll build real features that deliver real value from dashboard insights to internal tooling, from AI-powered workflows to backend integrations.

This isn’t a role where you’ll sit in a corner coding tickets. You'll be in the room, ideating alongside our Product Manager and Designer, and building end-to-end features that impact thousands of users. You’ll learn fast, take ownership, and contribute to a product that’s genuinely changing the way deals get done.

What You’ll Be Doing:

• Build, Ship, Repeat: Develop end-to-end product features using React, TypeScript, and PHP (Laravel). Deliver well-tested, maintainable, and scalable code.
• Think Like a Product Owner: Go beyond the code and understand the "why" behind the features and help shape them.
• Learn & Apply AI: Work on intelligent workflows, automation, and applied AI and even if it’s your first time, you’ll be supported to grow in this area.
• Move Fast, Learn Fast: Work closely with senior engineers and get rapid feedback. Learn modern practices, tooling, and architecture patterns.
• Own Small Projects: Take responsibility for features or internal tools and you’ll have the space to lead and the support to succeed.

What Success Looks Like:

• You’re shipping real value quickly - new features are being released into the hands of users, and you're confident in contributing across the stack.
• You own small projects end-to-end - scoping, building, testing, and iterating on meaningful product functionality with support from senior engineers.
• You’re learning fast - gaining confidence in areas like API design, databases, AI integration, and modern dev workflows.
• You’re making things better - proposing ideas, improving the user experience, and helping us refine how we build.
• You feel part of the mission - understanding how your work connects to the company’s goals, and feeling excited to contribute to the future of the platform.
• The team sees you as reliable and impactful - you communicate clearly, meet your commitments, and actively raise the bar for quality.

What We’re Looking For:

• 1+ years of experience in a frontend, backend or fullstack role
• Hands-on with either React/TypeScript or PHP/Laravel - ideally both but not essential if you’ve been more focused on only one of the languages.
• Curious about product design, user experience, and how software solves real-world problems
• Interest in the future of AI and automation in product development
• Comfortable in a fast-paced environment and proactive in asking questions or offering ideas
• You’re not just a coder - you care about what you’re building and why it matters

Bonus Points For:

• Familiarity with modern web APIs, MySQL/PostgreSQL, CI/CD workflows
• Passion or experience within startups or scaleups especially in SaaS, PropTech, B2B tools
• Exposure to agile teams, GitHub, testing frameworks, or performance monitoring
• A side project or two that shows your passion for building things

What’s in It for You?

• Competitive salary + benefits – share in our growth
• Private healthcare – including dental, optical, and more
• 25 days holiday + birthday off + duvet days
• Hybrid work – 3 days in-office (Central London/Carnaby St), 2 day WFH
• Snacks, drinks, and team lunches in our dog-friendly Soho office
• The chance to work future AI-powered, product-first software at scale
