We are a heavy user of Postgres and we have several custom extensions primarily written in C. We'd like to expand our team of developers who can support and maintain these extensions as well as help us create more. Other responsibilities could include (based on your interest) deep-dive SQL optimization, schema design and/or review, and troubleshooting (e.g. coredump analysis).
Besides experience with C programming and a deep understanding of Postgres the only other strict requirement would be that you are located in, and authorized to work in, the United States. This would be a full-time position. We are located in Atlanta but are fine with a remote employee for this position.
Please let me know if you are interested and I can share more details about the company and the product.
