Which Bay Area companies are bringing s/w engineers back to the office?

FWIW, it says Uber opened already, but returning to office is voluntary at this point, there are capacity limits (IIRC 20%), and as far as I know, most people are still working from home.

Intentionally not mentioning company name. Ours will bring up to 60% back to the office by June/Aug timeframe. People can opt to work from remote part of the time with mgmt approval. Some people can work remote full time with VP approval.

Are there any companies that are already back in the office? Have any announced plans to return by the end of May?
