Your role:

We are looking for a Buyer to build and own THEKER's purchasing function from the ground up.

THEKER builds physical robots. That means a continuous flow of electronic components, mechanical parts, sensors, cables, and custom hardware, often with tight timelines and no room for supply failure. Right now, purchasing is distributed across the engineering team. Your job is to change that.

You will create structure: qualify and manage suppliers, drive cost discipline, reduce lead times, and ensure the right components are available when the engineering and integration teams need them. You will work directly with Mechanical, Electronics, and Robotics Integration engineers on sourcing decisions, BOM management, and component availability, becoming the operational backbone of everything we build.

• Own the end-to-end procurement process: sourcing, RFQs, supplier selection, PO management, and delivery follow-up.

• Build and maintain a qualified supplier base for electronics, mechanical components, and custom hardware.

• Work with engineering teams on BOM management, component selection, and alternative sourcing when needed.

• Track pricing and lead times across suppliers, and act on what you find to cut cost and improve reliability.

• Monitor open POs and delivery timelines, and flag supply risks before they hit production or deployment.

• Manage inventory levels for recurring components, balancing availability against cash tied up in stock.

• Build procurement infrastructure from scratch: approval workflows, spend visibility, vendor evaluation criteria, documentation standards.

• Take on supplier negotiations directly as you grow into the role, with coaching from the team.
