Prototype Technician (Electronics Assembly & Prototyping – UAS Systems) (f/m/d)

As a Prototype Technician, you will play a critical role in bringing our UAS electronics from design to reality. You will be responsible for the precise assembly, rework, and validation of complex prototype PCBs used in flight-critical and mission-critical systems. Your craftsmanship and technical expertise will directly impact the reliability and performance of our airborne platforms.

This role requires exceptional hands-on skills in fine-pitch soldering, rework, and component-level troubleshooting, combined with a strong understanding of electronics assemblies. In addition to manual assembly, you will operate and further develop our in-house prototyping capabilities, including our pick-and-place (PnP) machine, to build small prototype and pre-series batches efficiently and with high quality. You will collaborate closely with hardware engineers during bring-up and validation phases, contributing practical feedback to improve design robustness and manufacturability. In our fast-paced development environment, you will be a key enabler of rapid iteration cycles and high-quality hardware releases.

What is your Day to Day Mission:

• Assemble complex prototype PCBs with exceptional precision and quality, including fine-pitch SMD components (e.g., QFN, BGA, 0402/0201)

• Perform high-quality soldering, rework, and component replacement on multilayer boards

• Professionally use hot air rework stations and related equipment for precise component removal and replacement

• Operate and program the in-house pick-and-place (PnP) machine for prototype and small pre-series builds

• Prepare stencils, apply solder paste, and manage reflow processes for high-reliability assemblies

• Inspect assembled boards using microscopes and measurement tools to ensure the highest quality standards

• Support hardware engineers during bring-up, debugging, and validation of prototypes

• Identify and resolve assembly-related issues, providing feedback to improve PCB design and manufacturability

• Maintain and organize component inventory for prototyping and small-batch production

• Contribute to the continuous improvement of in-house prototyping capabilities and workflows

What you bring to the team:

• Technical education in electronics (e.g., Electronics Technician, Mechatronics Technician) or comparable qualification

• Extensive hands-on experience in high-precision PCB assembly and rework

• Advanced soldering expertise for fine-pitch and high-density SMD components

• Proficiency in using hot air rework stations and professional soldering equipment

• Experience with reflow soldering, stencil printing, and PCB rework tools

• Interest in and ideally experience with pick-and-place machines and small-batch electronics manufacturing

• Strong understanding of electronic components, schematics, and PCB layouts

• IPC certification for PCB rework and repair (e.g., IPC-7711/7721) is a plus

• High level of attention to detail and commitment to quality

• Structured and reliable working style in a fast-paced prototyping environment

• Fluent in English; German is a plus
