Flex is building a finance super app for premium business owners — reimagining every single aspect of the financial workflow and financial services for any entrepreneur. The company has grown revenue 25x+ since publicly launching in September 2023 and is on track to achieve profitability by late 2025. Flex is focused on mid-market businesses ($3 - $100M revenue) that are largely overlooked by existing fintech solutions and reliant on slow and outdated regional banks. We are targeting a ~$1T revenue opportunity that is largely up for grabs.
Flex is a fully remote company and this role can be performed from anywhere.
The Role

As a senior software engineer you will have the opportunity to work across the entire stack with a focus on the back-end.

You should have a strong sense of ownership and enjoy taking projects from inception to release. As an early employee, you’ll be working with a nimble team of committed and talented engineers and having a large, long-term impact on technical design and engineering culture.
We are open to candidates from Canada, the United States, and Colombia.
