We’re Kingfisher, a team made up of over 74,000 passionate people who bring Kingfisher - and all our other brands: Castorama, B&Q, Screwfix, Brico Dépôt and Koçtaş - to life. That’s right, we’re big, but we have ambitions to become even bigger and even better. We want to become the leading home improvement company and grow the largest community of home improvers in the world. And that’s where you come in.
At Kingfisher, our customers come from all walks of life, and so do we. We want to ensure that all colleagues, future colleagues, and applicants to Kingfisher are treated equally regardless of age, gender, marital or civil partnership status, colour, ethnic or national origin, culture, religious belief, philosophical belief, political opinion, disability, gender identity, gender expression or sexual orientation.
We are open to flexible and agile working. Therefore, we offer colleagues a blend of working from home and our office, located in Kraków. Talk to us about how we can best support you!
At Kingfisher, we value the perspectives that any new team members bring, and we want to hear from you. We encourage you to apply for one of our roles, even if you do not feel you meet 100% of the requirements.
In return, we offer an inclusive environment, where what you can achieve is limited only by your imagination! We encourage new ideas, actively support experimentation, and strive to build an environment where everyone can be their best self. Interested? Great, apply now and help us to Power the Possible.
About the role
As part of Kingfisher’s Engineering Centre in Krakow, we are expanding our teams dedicated to Castorama Polska – one of the country’s most recognized DIY retail brands. These teams will be shaping the future of retail by building and evolving Castorama’s mobile app, e-commerce platform, and the back-office systems that power store operations across Poland. If you join us, you will not just be writing code – you will be directly influencing how millions of customers shop, browse, and interact with their local Castorama stores. From launching a new generation of mobile apps to streamlining in-store tech, your work will have a real, visible impact in your own backyard.
As a Lead Software Engineer within our frontend domain, you will play a pivotal role as both an expert individual contributor and a technical multiplier. You will be responsible for guiding your squad through complex and often ambiguous challenges, ensuring the delivery of high-quality, scalable solutions that align with long-term business goals.
You will provide technical leadership, coach and mentor engineers, and drive engineering excellence across the team. Working closely with Engineering Leads, Principal Engineers and Architects, you will shape technical direction, influence strategic decisions, and foster a strong culture of collaboration, innovation, and continuous improvement. With a passion for frontend technologies and a holistic mindset, you will help elevate both the technical capabilities and the impact of your squad.
