About The Position

We are seeking a skilled and detail-oriented Repair Technician to join our growing team. In this role, you'll be responsible for diagnosing, repairing, and maintaining hashboards - the core PCBA components inside Bitcoin miners. The ideal candidate has a background in electronics troubleshooting, advanced-level soldering and rework skills, and the ability to work both independently and collaboratively

Requirements

Advanced experience in electronics or PCBA repair/rework.
Basic understanding of troubleshooting equipment, e.g. - multimeter, oscilloscope, power supply helpful but we're willing to train individuals with a desire to learn.
Comfortable working with small SMD components under a microscope.
Understanding BGA/QFN/LGA rework techniques and thermal management.
Strong attention to detail and problem-solving mindset.
Familiarity with IPC repair standards (IPC-7711/7721 certification NOT required but helpful) and ESD best practices.
Good written communication for documenting repairs and collaborating with the team
