Who We’re Looking For
We are seeking an exceptional Lead Java/Fullstack Developer with a profound, product-first mindset. This isn't just a coding role, it's a leadership position where you will be the primary advocate for user experience and workflow excellence within our backoffice system.

You will set the technical and UX direction for our backoffice solution, ensuring it evolves into a truly intuitive, efficient, and scalable platform for non-technical users.
Champions the Internal User: You are deeply passionate (perhaps even obsessive) about workflow clarity and interface logic. You treat our internal (admin) users with the same care and respect a product designer shows external customers. You are compelled to build tools that people genuinely want to use.
Mentors and Elevates: As a Lead, you’re ready to guide, mentor, and set a high bar for technical quality and UX design for others working on the backoffice system. You take pride in simplifying complexity and enabling your teammates to deliver their best work.
If you thrive on full ownership, are energized by the challenge of solving complex business problems through elegant UX, and are ready to be the driving force behind a mission-critical platform, we want to talk to you. Come and help us define what a world-class backoffice system looks like.
