To create a systemd (systemctl) job, put your service description file in:
/lib/systemd/system/name.service
or
/etc/systemd/system/name.service
Then to enable it do: sudo systemctl enable name
Everytime, you edit the service definition file, you have to reload the daemon:
sudo systemctl daemon-reload
To control the service:
sudo systemctl {start,stop,restart,status} name
To lively monitor the logs, in another terminal do:
sudo journalctl -u name.service -f
