Formance is on a mission to redefine how developers interact with money as a first-class primitive and compose with finance.

Hidden through permissioned, vendor-locked infrastructure, money needs to rewire itself to empower product-first companies with the ability to create innovative financial applications. With the Formance Platform, we're putting agnostic primitives in the hands of engineers and their team. These primitives are available as open-source packages, and can be wired to the financial partner of your choice.

Formance is global native and serving enterprise companies around the globe, around the clock, to build and scale their financial applications. If this all sounds pretty exciting and you're looking for a place where you can play your best game and make a difference, we'd love to hear about you!

Start date: from August 2025

Who we are

Formance is on a mission to unlock the next generation of financial applications by solving today’s hardest problems in the space — with full flexibility and programmability to build unique and sophisticated financial products, with the most effective financial services providers. Our platform was built with a distinctive angle from the ground up, focusing on the flow of funds first to help businesses realize their product visions on a solid financial foundation.

Starting with an Open Source Ledger (i.e. a database for financial transactions), we’re building a comprehensive suite of modern financial backend modules, including native and automated reconciliation, workflow engines, and connectors with various financial services providers - e.g. Stripe, Adyen, Modulr, Wise, Atlar. This unique approach has made us the trusted financial backend for leading SaaS companies and financial institutions like Booksy, Doctolib, and Liberis, along with many others worldwide. Our success stems from the trust in our open-source foundation, the high level of programmability of our solutions, and our software-first approach, moving beyond traditional payment business models.

Formance’s team previously built Selency’s home-grown financial backend, which processes over €50M in GMV annually, and created Alsid, a cybersecurity company, from inception to acquisition.

Why join Formance now?

We’re at a pivotal stage of our growth, doubling down on sales and enterprise expansion worldwide. The market is currently untapped, with financial backends traditionally built in-house by companies like Square, Airbnb, Qonto, and Uber. With a global market valued at over $10bn and projected to reach $300bn+ in 2030 for SaaS and platforms only, you'll join us at the perfect time to capture this potential!

As part of our expansion, we're hiring an Implementation Engineer to oversee the post-sales phase with the founders and tech team including product implementation, day-to-day operations, and potential account expansion.

We're a team of 25, growing to 35+ soon. We're all about customer experience, product, and strong expertise. Becoming the financial backend for major SaaS platforms is about trust and proving our product's value in mission-critical environments.
