Senior ERP Specialist

We are looking for a Senior ERP Specialist to lead the integration of Microsoft Dynamics 365 Finance and Operations (F&O) across the company and build the ERP team. You will own the target process design, the implementation roadmap and the integration with production, procurement and finance, and you will build the ERP function as we scale from pilot plant to series production. This is a broad, high-ownership role. The ERP is the backbone that connects orders, materials, production and money. You will decide how that backbone is built, and you will be accountable for it working on day one of series production. About us We're a Germany-based rocketry startup currently in stealth mode, scaling up rapidly to meet the demand for high-performance, reliable, and scalable solid propulsion technologies for space and defense applications. We are building our first production facility in Steyerberg, Lower Saxony, and are applying our knowledge toward serial production of solid rocket motors. We are working hard to build something truly spectacular. To thrive here you will need to be comfortable working at pace, with the autonomy to make decisions and execute on them quickly. If you're excited by hard technical challenges and want a role where you will make a real difference each day to the future of the company, we may be the place for you. At our company, job titles and career progression are earned, not determined by years of experience alone. They reflect the responsibility you take on and the dedication you bring to each project. If you're ready to rise to the challenge, we'd love to hear from you.
