I'd suggest not using the shell script if you're installing as a system service as they typically run with root by default but you can set a user within the service file and setting a working directory under systemd.

So, within your service file:

[Service]
User=<username>
WorkingDirectory=<directory required>

It's also always worth checking journalctl for error reports on services.
