Head of Engineering

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

Our platform has garnered over 8,000 stars on GitHub , a testament to our active and growing developer community. Next-gen companies such as Mistral.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" , we also expect you to learn fast : make mistakes, but don't make the same one twice.

If you're excited by challenges and want to grow alongside a high-performing, supportive team, this is the place for you.
