We are looking for an Indonesia payroll expert who can help us with domain, statutory/ compliances aspects such as Taxes, deductions, reliefs, Govt. claims and CPF etc. This person will be working closely with our implementation team and help in process and requirement study at a client site in Indonesia followed by required documentation. This person should have good exposure and experience in Indonesia Payroll and should be able to speak/understand English and preferably Bahasa (Indonesia) as well. Initial need is for about 3 weeks for requirements gathering and documentation. After that, we would need this person for 3-4 weeks to do functional testing of product based on requirements and knowledge transition to on-going team. Since, this is short term need, we are looking someone who can take this up with a per day or per week pricing model.
