Data Engineer

About Us

Manukai stands for Manu_facturing and Kai_zen, a Japanese methodology of continuous improvement that translates to "change for better." In ancient Greek, Kai_ros means "the opportune moment."

We are a spin-off from ETH Zürich, aiming to bridge the gap between metal part design and machining. Our AI-powered technology empowers manufacturers to prioritize their clients' needs and deliver high-quality products to the market. Our primary focus is making an immediate impact, with client satisfaction as our utmost priority.

The Role

You will own data reliability, scalability, and efficiency across Manukai's systems. You will accelerate data-driven decision making and lay the groundwork for machine learning by delivering high-quality data and quantitative reports. You will build automation to scrape, generate, visualize, and label data; design and manage data warehouses; and collaborate closely with machine learning engineers and the founding team to ensure data needs are met. We value proactive contributors who bring ideas that shape our product and company.

About You

You are a team player who enjoys technical challenges. You appreciate short decision paths and can drive your ideas autonomously from concept to production. You contribute thoughtfully to architecture, design, and code reviews. You remove hurdles, thrive in a dynamic environment with evolving requirements, and are eligible to work in Switzerland.
