i modified it for you here: http://dpaste.com/775539/plain/

==================================
# network interfaces bindings

[Unit]
Description=Static Interface [%I]
StopWhenUnneeded=true
Wants=network.target
Before=network.target
BindTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device
After=basic.target

[Service]
Type=oneshot
TimeoutSec=0
Restart=always
RestartSec=30
RemainAfterExit=yes
ExecStart=-/usr/sbin/ip addr add 10.50.250.1/24 dev %I
ExecStart=/usr/sbin/ip link set %I up

[Install]
Alias=sys-subsystem-net-devices-eth0.device.wants/net.static at eth0.service
==================================

... then:

# wget -O /etc/systemd/system/net.static at .service
http://dpaste.com/775539/plain/
<<< modify the ExecStart as appropriate! >>>
# systemctl daemon-reload
# systemctl enable net.static at eth0.service

[maybe, first time only]
# systemctl start net.static at eth0.service

... and now whatever you put in the ExecStart(s) will execute every
time the device appears.
