• Excellent communication skills, both written and oral, along with effective teamwork abilities
• Superb focus and attention to detail, with remarkable work efficiency and accuracy
• Experience with soldering PCBAs, including soldering in tight spaces such as 0402 packages and high‑density ICs, installing jumpers, and performing dead‑bugging
• Expertise in manufacturing and repairing intricate testing systems
• Familiarity with Atlassian tools such as SVN, Confluence, and JIRA
• Basic comprehension of electronic principles and theory
• Skills in project management

Additional Requirements

• Must be willing to work extended hours and/or weekends as needed
