Join Hero Labs, where our mission is to empower humans to consume water sustainably!
At the heart of our mission is Sonic, our innovative smart shut-off valve, designed to be the most advanced leak protection system available. Sonic intelligently monitors water flow in homes and offices, detecting issues like burst pipes and slow leaks, and even identifies appliance usage – helping you save water, money, and the planet.
As an ambitious startup with roots in Poland and the UK, we’re seeking a dynamic accountant to propel Sonic globally. This role offers you a spectrum of financial responsibilities, from handling investment projects and shareholder relations to dealing with S(EIS), EMI, and more, encompassing both UK and international compliance. You won’t just be part of our present – you’ll be shaping the future of smart water technology.


Are you ready to take the financial helm? Your official title is up to you – “Financial Maestro”, “Numbers Whisperer”, or the classic “Accountant”.
What truly matters to us isn’t your background, accent, or how your CV looks.
It’s your drive, your mindset, and your ability to deliver results that count.
Join us if you’re eager to craft a top-quality financial framework and grow with a team that values high performance and rewards it generously. Let’s build something extraordinary together.
