About Us

E-finances is a B2B software publisher specializing in financial and treasury management solutions. Our solutions enable companies to optimize the management of their financial flows, improve their treasury visibility, and strengthen their financial performance.

We are in a full modernization phase: technical overhaul of our historical products, launch of new features, ramp-up of our stacks. This is the right time to join the adventure and leave a real mark on what we are building.

Why Join Us

• A true builder's role. You are not joining a frozen project: you actively participate in the redesign of our applications and in defining how they should evolve. Your ideas and initiative are expected, not just your code.
• Autonomy and Trust. You work in a small, close-knit team (one Tech Lead, three developers, one Product Owner), with the freedom to organize your work and propose your own technical solutions.
• Concrete career prospects. By joining a growing team on a strategic product, you have the opportunity to increase your technical responsibilities (architecture, mentoring, technology choices) over time.
• Flexibility. Flexible work organization and respected work-life balance, in an environment where performance is judged by results rather than presence.
• Meaningful challenges. Modernization of a real legacy (.NET Framework 3.5/4.8 to .NET 8), technical debt to reduce, new features to design from scratch: plenty to continuously expand your technical expertise.
• A quick and direct process. an initial discussion with our Tech Lead (via video call), then an in-person case study with the Director of E-finances.
