• Sending and administrating contracts via DocuSign, including terminations and renewals,

• Maintaining sales tax exemption documentation and supporting audit and tax preparation processes

• Improving workflows, documentation, and finance processes to increase accuracy, speed, and control

Besides your own team, you will be supported by 80+ Tosi Team Members across the globe. Your accurate role in the team is tailored based on your skills and preferences. You will report directly to the Chief Financial Officer Jussi Posti, based in Finland, and work closely with US sales leadership locally.
