Charlie is building the future of banking for the coming wave of millions of tech-comfortable retirees who deserve a bank built from the ground up for their unique needs, a bank they don’t have to get in line for, a bank that comes to them.

We are seeking a highly skilled Backend Engineer to join our team. This role will be responsible for creating a simple, transparent, and delightful banking experience for tech-comfortable retirees. You will be collaborating with everyone in the tech and product team to architect and build new systems from the ground up as well as maintain existing systems.

You’d be joining a highly experienced group of founders including our CEO Kevin Nazemi, who served as the Co-Founder and Co-CEO of Oscar Health (NYSE: OSCR), and a company financially supported by some of the most respected FinTech Investors.

  • Experience working with heterogeneous databases and data stores (SQL, NoSQL, Redis, ElasticSearch, etc).
