Senior software engineers are reluctant to leave their safe FTE jobs to go contract because they don't want to do sales, chase payments, manage a business, etc. We help contractors with that. Once a contractor goes full-time contract through Facet, we try to keep them always busy with as much work as they want. So yeah, it's hard to hire those types of devs on a single contract. It's also hard to find them on sites like Toptal or Upwork because they get priced out of the market.
