How's the candidate supply for Network, Database engineers?

I'm working on couple job descriptions for a Database Engineer and Network Engineer, both senior or staff level (8+ yoe). I know the candidate pool is flooded with pure CS folks but was wondering how it was for those with some hardware exp, i'm actually worried it'll be hard to fill the role?

Here's a brief description of skillset:

**DB Engineer:**

\-manage high amount of db data (TB+ possibly PB of hardware telemetry data)

\-python and SQL to gather data from hardware (such as switches, DSP) and put them into db (ETL)

Nice to have:

\-some backend/API development

\-understand FEC, SNR, temp, and link health etc data

**Network Engineer:**

\-understanding of data center network architectures (types of switches, servers, cables/pluggables like OSFP)

\-switch OS such as sonic

\-OSI layer 1/2/3 knowledge, pref cisco certified

\-understand FEC, SNR, temp, and link health etc data

Nice to have:

\-python scripting for SDKs and NMS

Degree: EECS > EE or CS

Myself - i'm a front end dev and product owner so these roles will work with me directly.
