# **About Lago**

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**](https://www.synthesia.io/) and [**Mistral.ai**](http://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.

- **Improve monitoring and observability** , ensuring proactive detection and resolution of issues.

- **Enhance security practices** , from IAM policies to data protection strategies.

- **Collaborate with engineers** to improve deployment processes and DevOps best practices.

# **What We’re Looking For**

- **Strong experience in infrastructure engineering** , DevOps, or SRE roles: 5 year+

- Expertise in **Kubernetes, Pulumi, and cloud environments (AWS/GCP)**.

- Experience managing and scaling **PostgreSQL** in production.

- Proficiency in **Ruby, Go or Typescript** (or willingness to learn).

- Passion for **open-source** and infrastructure-as-code principles.

- Ability to work autonomously in a fast-moving startup environment.

- **AI Forward Engineers** that are comfortable leveraging modern technology to improve their impact.
