**About Us** We are on a mission to make looking after your home effortless, and to clean up an industry that has too often left its workforce in the shadows. Batgroup is the company behind **Batmaid**, our English-speaking brand, and **PFA / Putzfrau.ch**, our German-speaking brand: a portfolio spanning direct cleaning, recruitment, and fiduciary services that has made us Switzerland's number one home cleaning company, with more than 4,000 cleaning professionals and a growing footprint across Europe. Our purpose goes beyond business. It is about people. Every cleaner who works with us deserves declared, insured, and properly protected employment, on permanent contracts governed by the sector's Collective Bargaining Agreement, with real access to pensions, sickness cover, and paid leave. By taking on the multi-billion-franc cleaning black market, we level the playing field, bring fairness to a sector that badly needs it, and give customers professionals they can genuinely trust in their homes. That is our fight, and it is why we rally behind **#fightblackmarket.** Technology is how we win it. We build the platforms, apps, and services that let thousands of customers book a trusted cleaning in a few clicks, and that let thousands of cleaners work with dignity and security. That is where you come in. **The Role** We are looking for a skilled **PHP Developer** to join our engineering team in Warsaw (hybrid) and help build the platforms and backend services at the heart of Batmaid and PFA.
