Backed by world-class investors and advised by industry titans, we’re building category-defining products with the freedom to ship ambitiously and own outcomes.

🥳 Regular socials and company off-sites (last time was Southern France and next time is in October).
🚀 A huge opportunity for career growth as you'll help shape a market-defining product.
The famous last words
Working at Light means you're embarking on an exciting journey to reshape the future of multinational financial operations. Our cheat-code is that we've built something like this before - and are now doing it again, only better.
