Depends. 1) Do you know how they work internally and maintain them (devops job). Can you build them (ex: http://www.scylladb.com/career-post/software-developer/ http://www.scylladb.com/career-post/software-developer/ ) ? 2) Build a nosql or contribute to an open-source one. See scylladb, seastar-project, seastar-pedis for examples. See https://github.com/phaistos-networks/Trinity https://github.com/phaistos-networks/Trinity and try to make it distributed (by including it in vespa.ai for example ). Create modules for redis. Contribute to citus-db. Or look at stack overflow jobs site with distributed systems. See their requirements and start building a resume with those. Makes sense ?
