Lemon.io helps companies in the US and Europe hire experienced engineers, from funded startups to teams like Klarna, Retool, and Pinterest. We’ve been doing this since 2015, and more than 1,500 companies have hired engineers through us.

We are looking for a Forward Deployed Engineer for our client. They are building a long-term Forward Deployed Engineering team in Europe to support multiple clients and projects across energy, manufacturing, transportation, and other operational sectors.

This is a full-time, long-term role rather than a single-project engagement. Engineers should be based in Europe and prepared to travel or work onsite with clients across Europe. Locations may include France, Spain, or other European countries. The length and cadence of onsite work will depend on each project’s progress; some deployments may run for 12–18 months and require extended periods on the ground.

Onsite period: onsite stays may be long-term , and individual deployments may run 12–18 months.

Hiring model: long-term full-time employment; direct hire is preferred.
