Integrations / Marketplace Engineer (F/M) - Paris/Lyon/Krakow

At LumApps and Beekeeper we connect over 7 million workers in more than 150 countries with the tools they need to do their best work. Our open Marketplace and modern extension points (APIs, webhooks, Embedded Apps, iPaaS connectors) let customers tailor our platform to any workflow, from shift scheduling to AI-powered language translation. Join a scale-up that still ships like a startup and invests heavily in developer experience.

If you would love to turn "Wouldn't it be cool if…?" ideas into Marketplace apps in days, not months then this is the role for you! We prototype and iterate directly with our partners and customers creating innovative solutions. If you love hackathons, API design, and the thrill of seeing something work and then go live in days this is the place for you.

As a Marketplace Engineer you will be in the heart of this iteration cycle with the opportunity to travel onsite to co-innovate with our customers in Europe and North America. Then work with our internal teams to turn these into valuable solutions available in our Marketplace.

This role is a rare opportunity to accelerate your engineering career working with senior leadership and opening the door towards difficult to land roles such as architect, product manager or tech lead.
