The right kind of job description is extremely vital to attract the best of the talents to your organization. Especially if you are a multinational it is even more important as the MNCs have particular standards that they maintain while attracting the talent pool.
Now if you are writing a sample job description for a vacancy of a technician, it is important you mention the field of operation of your company. Also required is the mention of the kind of machinery you want the prospective employee to work on. This is important because not all technicians know how to work on all kind of machineries. Besides a technician for medical equipment might be different from the one that operates textile machinery and so on. Hence the most important thing to mention is the kind of machinery and their required skill set and experience with each of the machineries mentioned.
Now that you have already mentioned the required skill set, also mention the expected responsibilities in terms of extension in timings, extra work and overtime in the job description format. Also mention if the prospective employee is required to work on repairs and maintenance as he may not necessarily be a pro at it and may not consider repairs as his primary job responsibility.
Above all, mention if you require any references from his past employer as his working relationships may affect the overall work culture of your organization. Also check if he is affiliated to any unions and whether this may be harmful to your organization.
