Senior Full Stack Engineer (React)

Company Overview:

We’re on a mission to revolutionise homeownership by building an AI-powered PropTech platform that makes managing a home effortless.

Homeownership should be simple, but today it’s anything but. From handling maintenance and repairs to finding the right service providers and staying on top of admin, managing a home is fragmented, time-consuming and inefficient.

We believe there’s a better way.

Our platform combines automation, expert guidance and seamless access to trusted services. By leveraging AI and proprietary home data, we’re redefining how homes are managed. What was once a reactive process becomes proactive, intelligent and stress-free.

We’re VC-backed, launching in 2025, and building the foundation for a global, scalable, AI-native platform that will transform home management.

Position Overview:

We’re looking for a Senior Full Stack Engineer to join our founding team and play a key role in building our AI solution for millions of users and businesses. You’ll primarily work on the interactive web application (frontend), but you should be brave enough to jump across the stack from time to time to ship features end-to-end. You’ll be collaborating closely with Product, Design, and Engineering to deliver a world-class user experience, and shape the way people interact with AI.

This position is fully remote, though it requires periodic (e.g., quarterly) travel to London, alongside offsites in Poland. Ideal candidates will be proactive and eager to embrace challenges, possessing the autonomy to significantly influence product direction and oversee projects from inception through to launch.

You will:

• Develop core web applications for end-users (B2C) and businesses (B2B).

• Collaborate closely with the team to design the technical solution that transforms visionary ideas into tangible value for millions of users.

• Conduct thorough code reviews, engage in technical discussions as well as design sessions, and ensure adherence to best practices that uphold high standards of code quality and maintainability, co-creating a resilient platform.

• Take initiative in problem-solving, proactively identifying and addressing potential setbacks throughout the development lifecycle.

Requirements:

• Minimum of 8 years of experience in frontend development, with expert-level proficiency in React and Next.js, with a strong understanding of modern frontend architecture, design systems, E2E automated testing, and best practices for responsive and performant interfaces.

• Prior experience in the Python ecosystem is a strong plus.

• Experience building and scaling interactive web applications (in a B2B and/or B2C model), with a strong understanding of enterprise-grade UX patterns.

• Ability to reuse and extend existing component libraries efficiently to accelerate feature development while maintaining consistency and quality.

• Experience working in a fast-paced, startup environment where rapid prototyping and iterative development are paramount.

• Excellent problem-solving skills, with a strong sense of ownership and accountability.

• Outstanding communication and collaboration skills, with the ability to lead projects and interface directly with senior management.

• Fluent English at a minimum B2+ level, enabling effective communication in a professional setting.

Package:

• Starting base salary on B2B: 25,000 - 30,000 PLN monthly

• B2B Contract

• Holiday policy: 26 days + bank holidays + sick leave

• Equity in the company at ~0.2%

• Latest hardware

• Fast progression pathway and compensation review as the company grows

• Access to cutting edge AI technology for experimentation and boosting productivity
