As a Senior Backend Engineer in the Conversions Tech team, you will enable our meal brands to meet ambitious growth objectives by creating a high-performing conversion funnel. This role is part of the Growth Alliance initiative, which drives the HelloFresh group forward through marketing powered by advanced MarTech capabilities and innovative product development.

We seek engineers who can think systemically, work autonomously, and elevate the standard for reliability in our tech solutions.
