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
