# About Lago

At Lago, we're on a mission to make Monetization simpler for tech companies.

As the leading open-source billing platform, we help businesses 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**.

Our platform has garnered around **10K stars on GitHub** , a testament to our active and growing developer community. Companies such as **PayPal** , **CoreWeave** , **Synthesia** , and [**Mistral.ai**](http://Mistral.ai) choose Lago for their billing. And we have barely spent any money on Marketing or Ads so far.

We're a team of ambitious, focused individuals who 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 continuously improve them. 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.

## Overview

We are looking for a Growth Chief of Staff to take founder-defined priorities and turn them into shipped systems. Someone who can operate across GTM, ops, and growth without needing a playbook handed to them.

This is not a fixed-scope role. Priorities shift. New problems emerge. What does not change is the expectation: you see what needs doing, own it, ship it, and turn it into a self-improving system.

## What You'll Be Doing

Examples of projects:

- Build and own account outreach and nurturing motions from scratch

- Improve website conversion and CRM handoff processes

- Manage press, social, and brand projects around founder-led priorities

- Build dashboards, alerts, and operating cadences that keep the team moving, accountable, and improving

- Turn founder-led motions into campaigns, workflows, and repeatable playbooks

- Use AI tools and automation, while keeping humans in the loop when necessary

## Who You Are

- **You take the owner seat.** When a founder drops a half-formed idea, you do not wait for a follow-up. You turn it into a plan, identify what is missing, and own the _outcome_.

- **You thrive on shifting priorities.** This role will change shape as Lago grows. You're not looking for a rigid job spec. You're energized by being handed a new problem, figuring out the approach from scratch, and driving the impact.

- **You communicate before you're asked.** You share what you're working on, where things stand, and when something isn't working. Proactively, without needing a check-in to prompt you.

- **You're curious and hands-on about technical and AI products.** You don't need to be an engineer. But when you're evaluating a company, you read the docs, try the product, and build prototypes or workflows to understand it deeply. You understand what an API, a webhook, or an MCP is, or you can figure out a new technical concept quickly and explain why a customer would use it. That curiosity and builder-first mindset are non-negotiable.

- **You're ruthless about what actually matters.** You can look at five possible projects and correctly identify the one that moves the needle this week. You don't confuse activity with impact.

## Who You're Not

- Someone who arrives wanting to audit everything and start fresh. The priority is to double down on what already works.

- A strategist who produces decks. You produce shipped things.

- Someone focused on inputs. Outputs and impact are the north stars.

- Someone easily overwhelmed by things they have never done before or technical concepts. It has never been easier to learn new skills.

## Requirements

- 5+ years of experience in Growth Ops, GTM Ops, RevOps, BizOps, or a Founder's Office role with genuine GTM ownership

- Proven track record of building workflows, dashboards, and operating cadences, not just coordinating them

- Experience breaking down undefined problems: taking a business need and turning it into prioritized workstreams, aligned teams, clear steps, shipped outcomes, and feedback loops

- Comfortable with CRM, automation, and project management tooling, and curious enough to figure out what you haven't used before

- Enough marketing and business intuition to understand audience, timing, and messaging

**Nice to have**

- Experience in B2B SaaS, developer tools, or technical infrastructure environments

- Exposure to API-driven products, usage-based pricing, or billing business models

- French language skills

## Why Join Lago?

- **Work with top-tier international talent** : Join a team that values excellence, slope over intercept, and accountability. We have convinced top-tier investors and companies to trust us with mission-critical systems like billing. We have 12+ nationalities on the team and are building a global company with a global culture.

- **Shape the future of monetization and fintech** : The world is changing. Monetization systems are shifting with AI, and you will be at the forefront of this revolution.

- **Fully remote with frequent trips to the US** : Work from anywhere in Europe

- **Competitive package** : Competitive salary and stock options
