Frontend Developer (Flutter)

About Zimble Systems

The banking and financial sector is ripe for disruption. For too long, innovation has been slowed by massive capital requirements and complex legacy systems. Zimble Systems is on a mission to change that. We are building a next-generation cards and payment processor from the ground up to redefine how financial institutions approach card issuance and processing.

We are introducing a unique model that allows our clients to modernize their infrastructure incrementally, reducing costs and unlocking powerful new revenue streams. By democratizing access to the payment ecosystem, we are accelerating innovation and breaking down the barriers that have held the industry back.

We are in stealth mode, seed-funded with a robust runway of over 2 years, and are now building our core engineering team. This is a rare opportunity to get in on the ground floor and have a direct, tangible impact on our product, culture, and success. You will be designing and building the foundational systems that will power the future of finance.
