The Role

We’re hiring a Forward Deployed Engineer to join our Product team.

This role is ideal for engineers who enjoy solving real-world customer challenges hands-on. You’ll work directly with users to support their implementation of Lago, guide them through architectural and product decisions, and build or adapt code that helps them succeed.

You’ll act as a bridge between the user and Lago’s internal teams — writing production-level code, improving onboarding assets, supporting complex integrations, and channeling user feedback directly into our product development cycle.

Responsibilities

  • Lead technical implementation efforts for strategic users — from initial architecture reviews to production deployment
  • Write scripts, integration templates, and lightweight services to support custom use cases
  • Contribute to Lago’s open-source SDKs, example repositories, and public documentation
  • Collaborate with users’ engineering teams to resolve complex integration challenges
  • Identify edge cases and implementation patterns, and feed them into product discussions
  • Build internal tooling and utilities that support faster and more robust deployments
  • Act as a hands-on technical advisor to both internal and external stakeholders

Requirements

  • 3+ years of experience as a Software Engineer or in a technical role working with external users
  • Strong backend skills, especially in Ruby on Rails
  • Comfortable with PostgreSQL, Docker, Sidekiq, Clickhouse and event-based or asynchronous processing
  • Familiarity with RESTful APIs, webhooks, authentication flows, and OpenAPI specifications
  • Experience working with background jobs, queuing systems, and production environments
  • Excellent debugging and communication skills
  • Based in or willing to relocate to Paris, with in-office presence at least 3 days a week
  • Bonus: experience in billing infrastructure, SaaS metering, or open-source development

Why Join Lago?

  • Work on a product loved by engineers and product teams
  • Join a lean and ambitious team building foundational infrastructure
  • Contribute to an open-source project with real-world impact
  • Competitive compensation and early equity in a fast-growing company
