Job description:

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](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.

## Overview

We're hiring an Engineering Squad Lead to take full ownership of one of the focused domains here at Lago: shipping features, keeping production healthy, and coordinating the team around you.

This is a role that blends hands-on technical contribution with operational leadership. You'll stay close to the code while also being the person who keeps the squad moving: scoping work with Product, unblocking engineers, owning production incidents, and making sure the team is building with quality and velocity.

You won't be handed a fully-formed system to maintain. Lago is a fast-moving product in a complex domain, billing infrastructure where precision and reliability genuinely matter. You'll need to make sound architectural decisions quickly, communicate trade-offs clearly, and hold a high bar without slowing the team down.

## What you'll be doing

**Technology**

- Share technical authority with the Staff Engineer for your squad's domain: evaluate trade-offs together and drive architecture decisions

- Stay hands-on: code review, prototyping, contributing to critical paths

- Maintain code quality and review standards within the squad

- Own the code health of your domain

**Delivery**

- Own the squad's roadmap execution for the quarter

- Run sprint planning, keep work moving, and unblock engineers day-to-day

- Ensure the squad is prepared for biweekly product demos and decide who presents

- Act as the primary engineering point of contact for Product: scope features, communicate trade-offs, and align on priorities

**Production**

- Own production health for your squad's domain: monitor dashboards (Grafana, Sentry), respond to alerts, and resolve incidents

- Triage and resolve customer-reported issues within SLA targets, working in coordination with Customer Success

- Monitor and address CVEs and security vulnerabilities within your domain

**People**

- Coordinate a squad of up to 10 engineers

- Run operational 1:1s, give day-to-day feedback, and flag performance signals to the Head of Engineering

- Coordinate the onboarding of new team members into the squad

**Process**

- Define and adjust the squad's ways of working: balancing agility and discipline as the team and product evolve

- Drive engineering excellence: track DORA metrics, reduce cycle time, raise the quality bar

- Continuously improve how the squad works based on team feedback and results

## Who you are

- A credible technical leader who can collaborate closely with engineers because you're still in the work

- A clear communicator who can scope a feature with a PM, explain a production incident to a non-technical stakeholder, and give direct feedback to an engineer — all in the same week

- Operationally strong: you keep the trains running without needing a system to tell you what needs attention

- Someone who cares about team health as much as delivery — you notice when an engineer is stuck or disengaged and do something about it

- Comfortable holding a high quality bar in a fast-moving environment: you know when to move quickly and when to slow down and do it right

## Who you're not

- You're not someone who manages from a distance, you stay close to the work and the people doing it

- You're not a blocker — decisions get made, trade-offs get communicated, and the team keeps moving

- You're not indifferent to production — a customer incident or a flaky dashboard bothers you until it's resolved

- You're not a siloed thinker — you collaborate across squads, with Product, and with CS without needing to be asked

## Requirements

- 8+ years of software engineering experience (ideally 2/3+ in a Squad or Tech Lead position), with a strong command of backend systems and production environments

- Track record of shipping reliable, high-quality software in a fast-moving product company

- Comfortable working in a complex technical domain: distributed systems, APIs, data integrity, or similar

- Strong communication skills — written and verbal, with the ability to bridge engineering and product effectively

- Experience owning production: incident response, monitoring, on-call, SLA ownership

**Nice to have**

- Experience in billing, fintech, or usage-based pricing infrastructure

- Familiarity with DORA metrics and engineering effectiveness frameworks

- Background working in or contributing to open-source projects

- Experience working with Ruby on Rails or a similar backend stack

- Exposure to developer tooling or API-first product companies

## Why Join Lago?

- **Work with top-tier talent** : Join a team that values excellence, ambition, and accountability

- **Shape the future of fintech** : Be part of a fast-growing company building the best open-source billing platform

- **Hybrid work model** : Work from anywhere in Europe or join us in our Paris office

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

- **Make an impact** : Your squad's work will be building billing infrastructure for companies like PayPal, CoreWeave, Synthesia, and [Mistral.ai](http://Mistral.ai)
