Diversity matters
We are building a brand that represents the people of the world. It’s what you do that counts, and we are always looking to expand perspectives and voices to shape our future.
We see you, we celebrate you, we want you!
Who we are
You might know us as the inventors of the bath bomb, but there’s more to this great-smelling, partly employee-owned, family-run company than pioneering cosmetics. We believe our business should put more back into the world than it takes and demonstrate that capitalism can be a force for good.
The Living Wage Foundation’s statement 'a hard day's work deserves a fair day's pay' is one that we are proud to commit to in the UK. As an accredited Living Wage employer, we put our people first and fight cruel practices like animal testing, promote regeneration, and show that it is what’s inside that counts - whether that’s an ingredient in a product, or the minerals in a smartphone.
The role

In this role, you’ll focus on the engine under the hood—ensuring our APIs, databases, microservices, and server-side logic are fast, reliable, secure, and built to scale. You will work across product teams to validate approaches, catch complex edge cases early, drive automation, and ensure feature updates never compromise global stability.
