Here's a personal anecdote: my father is an engineer at a small, 8-person company. He's 68. They use two languages: C and Java. The short story is, they created a system for telco companies in late 90s. Said system deals directly with specific Telco hardware and needs to run real-time fast. The system is over 20 years old and despite this or that patch over the years its core remains the same. So there's a C part, which is the engine and is really performant, and a Java part, admin tooling, testing and integration. So I guess if I had to find companies with C jobs I would try: - niche jobs/industries - small companies - decades old systems The problem is that those aren't usually on the mainstream channels for job searching, and they may take years to open a single position.
