Shape the Future of AI Solutions at Lean FS
Join a team dedicated to bringing AI into the real world. We guide companies through their entire transformation — providing unique training on real data, strategic advisory, and hands-on development. We build both tailored client applications and our own proprietary products. From smart construction platforms to the global forefront of financial AI agents, we engineer software that turns ambitious ideas into running code.
Our Culture & Values
At Lean FS, we value pragmatism over politics and impact over busywork. We are builders, strategists, and problem-solvers who thrive on intellectual curiosity, operating exactly where advanced AI meets real-world business needs.
We believe the best results come from exceptional talent given the freedom to execute without bureaucratic hurdles. If you are looking for a high-trust environment where you can move fast and directly shape the future of our company and clients, you belong here.
Real Projects. Real Responsibility. From Day One.
You won't spend months watching from the sidelines. From your first week, you'll be embedded in live client projects — contributing to strategy sessions, writing production code, or shaping AI workflows that go straight into business operations.
We pair junior and senior team members on purpose. You'll get direct mentorship, honest feedback, and the freedom to propose ideas that can change the direction of a project. Growth here isn't a slide deck — it's built into every sprint.
