<h1><strong>About Lago</strong></h1><p style="min-height:1.5em">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 <strong>$22 million in funding</strong> from top-tier investors including <strong>Y Combinator</strong> and <strong>FirstMark</strong>, reflecting strong confidence in our vision and growth. Our platform has garnered over <strong>9,000 stars on GitHub</strong>, a testament to our active and growing developer community. Companies such as <strong>PayPal</strong>, <strong>CoreWeave</strong>, <strong>Synthesia</strong> and <a target="_blank" rel="noopener noreferrer nofollow" href="http://Mistral.ai"><strong>Mistral.ai</strong></a> choose 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 <strong>reliability and proactivity</strong>—we trust each other to own tasks, drive them to completion, and adapt quickly. While we encourage you to <strong>try fast and "fail fast"</strong>, we also expect you to <strong>learn fast</strong>: 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.</p><p style="min-height:1.5em"></p><h1><strong>Overview</strong></h1><p style="min-height:1.5em">We're looking for a Senior Backend Ruby Engineer to contribute to Lago's core product and help scale our open-source billing infrastructure.
