Does this mean that my processes need some synchronization primitive of their own to not to concurrent writes?

Afaik SQLite in WAL mode takes your writes but still serializes the commits, so no SQLite-specific synchronization primitives needed. You might run into SQLITE_BUSY, in which case you can play with the timeout https://www.sqlite.org/c3ref/busy_timeout.html
