ABOUT INVERSION

At Inversion, we build software for interesting, high-impact international projects.


Founded in 2018, we’ve grown steadily by working with clients across the USA, UK, UAE, and Bermuda, while building a globally distributed engineering team.


We are a 100% remote company, with team members currently working from South Africa, Pakistan, Portugal, and the Netherlands.


A large part of our work is in the reinsurance and financial systems space — building systems that support complex, real-world risk and financial operations.


We also work on projects in the AI and blockchain space, so there is no shortage of interesting technical challenges.
