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 including Y Combinator and FirstMark, reflecting strong confidence in our vision and growth.
Our platform has garnered over 9,000 stars on GitHub, a testament to our active and growing developer community. Companies such as PayPal, CoreWeave, Synthesia and Mistral.ai 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 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.
We're looking for a Senior Product Engineer to help drive Lago's core product forward — someone who obsesses over what gets built and why. You'll work at the intersection of engineering, product and design, owning features end-to-end: from shaping requirements with customers to shipping and iterating in production. This is a high-ownership role for someone who doesn't want to wait for a spec — they want to write it, then build it.
Nice to have

No applications, no recruiter spam. Just the intro.
A few questions to make sure this role is the right shape for you. Two minutes.
I write the intro, send it to the founder, and handle the back-and-forth.
If they’re a yes, I book the chat. You show up — that’s the whole job-hunt.
