Jobs in Montpellier, France

At Lago, we’re on a mission to make billing simpler, more transparent, and more adaptable for SaaS companies.

As the leading open-source billing platform, we empower businesses to build flexible pricing models and scale with confidence.

We also raised over $22 million in funding from top-tier investors, reflecting strong investor confidence in our vision and growth.

Our platform has garnered over 7,000 stars on GitHub, a testament to our active and growing developer community.

Next-gen companies such as Mistral.ai, Together.ai, Groq, and Laravel chose Lago for their billing.

We’re a team of ambitious, focused individuals who work together to solve hard problems with excellence and accountability.

At Lago, we value reliability and proactivity—we trust each other to own tasks, drive them to completion, and adapt quickly. While we encourage you to try fast and “fail fast” (if needed), we also expect you to learn fast: make mistakes, but don’t make the same one twice.
