How to Apply
Apply NowABOUT Inversion Limited
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. When large-scale events occur and insurers need additional backing, reinsurance systems step in — and the software behind those systems needs to be precise, reliable, and scalable.
We also work on projects in the AI and blockchain space, so there is no shortage of interesting technical challenges.
